Welche Konsequenzen hat Storfers Konzept einer antihistoristischen Schreibweise, sein Postulat der "Erschütterung der bequemen chronologischen Erklärungsweise", wie er schreibt, für seine Geschichte der Wörter? Welches sind die Voraussetzungen und Prinzipien seines Projekts einer "Wortforschung" als "Kulturgeschichtsforschung"? Storfer nähert sich seinem Gegenstand von zwei Seiten her. Zum einen unterstreicht er die Sprachlichkeit des Quellenmaterials, auf das sich, so betont er, "jede Geschichtsforschung" stützt. Zum anderen fragt er danach, in welchem Sinn sich Geschichte in der Sprache ablagert.
The studies of Cyclops O.F. Müller, 1776 have more than two centuries of tradition in Fenno- Scandinavia, yet, basic taxonomic questions remain unresolved and the limits of the distributional area are very poorly understood in the majority of the taxa (11+) occurring in the region. Based on the types and other materials we redescribe two species, C. lacustris G.O. Sars, 1863 and C. bohater Koźmiński, 1933, the latter being reported here for the first time from Fenno-Scandinavia; lectotypes of both species have been designated herein. Setulation characters of the antennal coxobasis- and maxillulary palp setae and P1 medial spine, as well as the spine formula of the terminal exopodal segments of the swimming legs (3433) in the adult female distinguish C. lacustris and C. bohater from their congeners. An identification key is provided to the Cyclops species of Fenno-Scandinavia, including information about both the female and male morphology. Although the limited material does not allow us to define the species range limits, our data nevertheless support a Northern European distribution in C. lacustris, and Northern and Central European distribution in C. bohater, while the records from the southern Palearctic need further verification.
Bothriomyrmex enigmaticus sp. nov. is described from the island of Hispañola based on one nest collection. This is the first collection of the genus Bothriomyrmex (Emery, 1869) from the Caribbean region, and the second species to be described from the Americas. While sharing several characters with B. paradoxus (Dubovikoff & Longino, 2004) from Costa Rica and Honduras, B. enigmaticus sp. nov. diverges in several key characters, including palp formula. However, a morphometric comparison to Palearctic species of the tribe Bothriomyrmecini suggests affinities to B. paradoxus, Chronoxenus wroughtoni (Forel, 1895) of the eastern Palearctic, and to a lesser extent an undescribed species of Arnoldius (Dubovikoff, 2005) from Australia and B. corsicus (Santschi,1923) of the western Palearctic.
Käte Hamburger nimmt im Folgenden mehr Raum ein, weil der Weg ihrer Theoriebildung vor dem Hintergrund der anderssprachlichen Exilerfahrung ein ungleich verwickelterer ist. Ihr Denkstil potenziert sich - anders als bei Susman, die ins Exil nach Zürich ging und den Verlust dialogischer Denk- und Schreibformen zeitlebens zu kompensieren suchte - im Gang durch die Fremdsprache auf der Folie der eigenen Sprache und Grammatik und erweist sich als konsequent monologischer. Einer Einführung zu den für die Theoriebildung symptomatischen Aspekten anhand einer kurzen biografischen Skizze Hamburgers folgt der Abschnitt "Wer spricht?", der die begriffliche Trennungsleistung Susmans und die Verwerfungsgeste Hamburgers als eine literaturwissenschaftliche Arbeit am Ich beleuchtet. Ein weiteres Kapitel konstelliert ungeschriebene und umgeschriebene Arbeiten der Autorinnen angesichts einer abgerissenen und von Hamburger als 'tot' bezeichneten Wissenschaftstradition. Der letzte Teil schließlich bündelt und ergänzt die Beobachtungen und bezieht sich zurück auf den Ausgangspunkt - die Auflösung von Denkräumen.
"Auflösung des Judentums" : zu einem literaturwissenschaftlichen Großprojekt Friedrich Gundolfs
(2015)
Von seiner jüdischen Herkunft trägt das wissenschaftliche Werk Gundolfs keine merklichen Spuren. Im Gegenteil hat er solche Spuren systematisch verwischt. Völlig unkenntlich sind sie damit allerdings nicht geworden. Zwischen den Zeilen prägt just sein 'abgelegtes' Judentum wesentliche Teile von Gundolfs Wissenschaftskonzeption, so auch deren sprachliche Verfasstheit und den Zuschnitt ihrer wichtigsten Gegenstände. Auf der Grundlage dieser Annahme will ich im Folgenden ein paar Schlaglichter auf einige wenige, sehr wohl aber repräsentative Gundolf'sche Texte werfen. In Augenschein zu nehmen sind dabei zwei Themenkomplexe: Erstens Gundolfs Vorstellungen von Literatur, Heldentum und Geschichtsphilosophie, die einen zutiefst apolitischen Geschichtsbegriff zu erkennen geben, der ein Phänomen wie die deutsch-jüdische Geschichte nicht mehr erzählbar macht, der v. a. aber die Huldigung eines Kunstideals impliziert, das als heidnisch-christliche Symbiose imaginiert wird. In diesem Kontext wird durchgehend auch die Frage nach den Implikationen einer Wissenschaftsprosa virulent, die sich als performative Umsetzung eines Heldenkultes und säkularen Gottesdienstes begreift und die das Judentum religiös, historisch und kulturell gleichermaßen zur Leerstelle macht. Zweitens Gundolfs Konzeption des 'deutschen Geistes', wie sie prominent bereits im Titel seiner bekannten Habilitationsschrift 'Shakespeare und der deutsche Geist' aus dem Jahr 1911 auftaucht. Es ist in erster Linie die dezidiert transnationale Anlage des 'Deutschtums', die es hier zu analysieren gilt.
Mit Moritz Veit (1808−1864) ist dieser Beitrag einem Intellektuellen und Verleger gewidmet, dem die deutsche Sprachkultur des 19. Jahrhunderts wesentliche Impulse verdankt. In der Geschichte der politischen Emanzipation und der gesellschaftlichen Integration der deutschsprachigen Juden haben seine politische und verlegerische Tätigkeit eine nachhaltige Rolle gespielt. Dazu werden zunächst in einem Überblick Leben und Werk Veits in Erinnerung gerufen, das nicht nur aufs Engste mit der deutschsprachigen Wissenschaft des Judentums des 19. Jahrhunderts verbunden war, sondern auch mit der Entwicklung der Philologie als wissenschaftliche Disziplin. Am Wirken von Moritz Veit - so die These des Beitrags - werden nicht nur zeitgenössische Vorstellungen von Wissenspopularisierung sichtbar, sondern auch, dass für ihn das Zugleich von politischer Anteilnahme, literarischem Schaffen und Verlagsarbeit ebenfalls die Teilhabe an der deutschsprachigen Kultur bedeuteten. Vor diesem Horizont soll auch das literarische und publizistische Programm des Verlags Veit & Comp. vorgestellt werden. Zudem wird auf Moritz Veits Einsatz für die Interessen der preußischen Juden und seine politische Arbeit sowie die Rolle im Börsenverein der Deutschen Buchhändler eingegangen.
Die rebellische Geste wie die intellektuelle Programmatik der Wende des jungen Scholem wird durch eine besondere Aufmerksamkeit auf die 'Sprache' im Allgemeinen und die 'deutsche' wie die 'hebräische' Sprache im Besonderen begleitet. Das Problem der Sprache stellte sich Scholem auf zwei Ebenen: auf derjenigen der 'parole', der Sprachpraxis, sowie auf derjenigen der 'langue', der Sprachtheorie. Im Fokus stehen hier primär zwei sprachpraktische Ebenen: erstens eine 'kulturpolitische', die von der Konkurrenz zwischen der bestehenden deutsch-jüdischen und einer entstehenden neuhebräischen Sprachkultur geleitet ist; zweitens eine 'historisch-philologische', die zunächst vom Problem des Übersetzens des Hebräischen ins Deutsche ausgeht und letztlich auf die Begründung eines neuen Begriffs der Philologie zielte. Darüber hinaus verhandelte Scholem die Sprache auch auf zwei theoretischen Ebenen: einer 'mathematisch-philosophischen', die die Wahrheitsfunktion der Sprache umfasst, sowie einer 'theologischen' und 'mystischen' bzw. 'kabbalistischen' und somit einer spekulativen Metaphysik der Sprache. Diese theoretisch-spekulativen Ebenen von Scholems Sprachreflexion begründen zwar auch seine Vorstellung der Sprachkultur der Juden, können hier aber im Hintergrund stehen.
Skizzenhaft soll im Folgenden die von Mauthner entwickelte, spezifische Form politischer Sprachkritik im Lichte von Reflexionen seiner jüdischen Zugehörigkeit betrachtet werden. Mauthners Sprachkritik erweist sich in dieser Perspektive als eine eigenständige Form von 'Sprachpolitik', die mit den zeitgleich von Ferdinand de Saussure entwickelten Anfängen einer linguistischen Sprachwissenschaft ebenso wenig gemein hat wie mit der vergleichenden Sprachforschung des 19. Jahrhunderts. Gegen einen 'Fetischismus mit Worten' in den Wissenschaften setzt der stupend belesene Sprachphilosoph einen aufgewerteten Dilettantismus, pointierte Bonmots und parodistische Verfahren.
Diplura C.L. Koch, 1850 is a mygalomorph genus with putative records from Central and South America. The type-species Diplura macrura (C.L. Koch, 1841), originally described from West Indies, is poorly known and represented only by its holotype. Most of the 20 species currently included in the genus lack modern taxonomic descriptions, as D. lineata (Lucas, 1857), from Rio de Janeiro state, Brazil. Males and females of Diplura macrura and D. lineata are herein redescribed. New junior synonyms of D. macrura are identified (Linothele bicolor (Simon, 1889), Diplura uniformis Mello- Leitão, 1923, and the two junior synonyms of the latter species, Thalerothele minensis Mello-Leitão, 1926 and T. aurantiaca Mello-Leitão, 1943). Also, two junior synonyms are established for D. lineata: Diplura fasciata (Bertkau, 1880) and Diplura nigridorsi (Mello-Leitão, 1924). The type-locality of D. macrura is corrected to São João del Rei, Minas Gerais state, Brazil. D. macrura is restricted to the state of Minas Gerais and D. lineata to the state of Rio de Janeiro. The type-locality of D. parallela (Mello-Leitão, 1923) is also corrected from Argentina to Paraná state, Brazil. The distribution of Diplura is now restricted from south Panama to north Argentina, excluding previous erroneous records for Cuba and West Indies. The six synonymies herein established help to clarify the genus composition, which includes now 17 valid species.
Eight species of the genus Notosemus Förster, 1869 (Hymenoptera: Ichneumonidae) are reported, three of which are new to science: N. albimaculatus Sheng & Sun, sp. nov. and N. planus Sheng & Sun, sp. nov., both collected from Xizang Autonomous Region, SW China, and N. wugongicus Sheng & Sun, sp. nov., collected from Jiangxi Province, S China. One new record for China, N. bohemani (Wesmael, 1855), was reared from Zeiraphera griseana (Hübner, 1789) (Lepidoptera, Tortricidae), a leaf pest of Larix principis-rupprechtii Mayr. (Pinaceae) in Ningxia Hui Autonomous Region, NW China. A key to the species of the genus Notosemus is provided.
Phylogenetic analyses of the highly diverse (non-marine aquatic) gastropod family Hydrobiidae Stimpson, 1865 have revealed seven main lineages, most of which represent subfamilies. The subfamily Pseudamnicolinae Radoman, 1977, and specifically the genus Pseudamnicola Paulucci, 1878 (mainly inhabiting western and central Mediterranean regions), contributes substantially to this hydrobiid richness. Most of its congeners have been described in terms of their shell and penis features, which are of limited diagnostic value. Hence, the taxonomic status of some Pseudamnicola species needs to be revised, particularly of those inhabiting marginal regions, such as the Ponto-Caspian domain, largely occupied by the subfamily Pyrgulinae Brusina, 1882. Here we present a molecular phylogeny including species of both subfamilies along with extended morphological descriptions to confirm assignments of the Iranian species Pseudamnicola zagrosensis Glöer & Pešić, 2009; Sarkia kermanshahensis Glöer & Pešić, 2009 (originally within Pseudamnicola) and P. saboori Glöer & Pešić, 2009. Our COI-based tree rejects these assignments suggesting a new potential lineage, sister to the pyrgulinid species, and comprising three genera: Shadinia Akramowski, 1976, Intermaria gen. nov. and Persipyrgula gen. nov. These genera differ molecularly by 3.6%–8.5%, and are diagnosable by penis, female genitalia and radula features. Our findings evidence the high morphological variability of pyrgulinid species and provide insight into the origins and evolution of the freshwater Ponto-Caspian fauna.
A new cheilostome bryozoan genus, Powellitheca gen. nov., is erected here for three species from New Zealand, one of which has been previously assigned to Emballotheca Levinsen, 1909, but which differ significantly from the Australian type species of Emballotheca, E. quadrata (MacGillivray, 1880). Notably, whereas Emballotheca has a cormidial orifice (i.e., formed by numerous neighbouring zooids), and lepralielliform ooecia, the orifice of Powellitheca gen. nov. is formed by single zooids and ooecia are of the microporelliform type. The introduction of a new family, Powellithecidae fam. nov., becomes necessary because of the nonconformity of Powellitheca gen. nov. with other known families having microporelliform ooecia. In addition to the Recent type species Powellitheca terranovae gen. et sp. nov., one other new Recent species, P. labiosa gen. et sp. nov., and a Plio-Pleistocene fossil species, Monoporella waipukurensis Waters, 1887, are assigned to the new genus.
The New World Clistopyga chaconi species group is revised. Eleven species are described as new: C. amazonica sp. nov., C. cinnamoptera sp. nov., C. cuscoensis sp. nov., C. hayesiana sp. nov., C. melanoptera sp. nov., C. misionensis sp. nov., C. mocaguae sp. nov., C. orellanae sp. nov., C. porteri sp. nov., C. rondoniae sp. nov. and C. yabuquensis sp. nov. Additional morphological data are provided for the previously known species, C. caramba Castillo & Sääksjärvi and C. chaconi Gauld. An illustrated identification key to all species of the group is provided. The Clistopyga chaconi species group appears to be most diverse at the Andean and Amazonian interface in western South America.
A new troglobitic species of the previously monotypic genus Biokoviella Mršić, 1992, B. mosorensis Antić & Dražina sp. nov., is described from caves on Mt. Mosor, Croatia. In addition to this, B. mauriesi Mršić, 1992, is partially re-described, and the taxonomic status of the family Biokoviellidae is re-considered. The genus Biokoviella is placed in the subfamily Biokoviellinae Mršić, 1992 stat. nov. within the family Anthogonidae Ribaut, 1913. The relationship of the genus Biokoviella with other anthogonids is briefly discussed, and a distribution map of the genus is presented. Notes on ecology and coinhabitants of the genus Biokoviella, and new data on some Balkan anthogonids are also included in the paper.
F.T. Kützing introduced Cocconeis molesta with only an uninformative description and a poor illustration: C. molesta has small, oblong valves and is an epiphyte. Another species, Cocconeis diaphana, described by William Smith, is said to have larger valves than C. molesta, with frustules that are relatively oblong. Smith described two forms: one with a distinct fascia on its raphe valve (var. β), the other without this feature. A third species, Cocconeis dirupta was described by Gregory, who expressed doubts that it differed from C. diaphana. Finally, Cocconeis molesta var. crucifera Grunow was first introduced in Van Heurck’s Atlas but was subsequently treated by Van Heurck as a synonym of C. molesta. No previous account has examined the type material of these species. In this paper, we undertake that task and examine type slides and raw material in order to discriminate these different taxa. We conclude by recognizing three species: Cocconeis molesta Kütz., C. diaphana W.Sm. and C. dirupta W.Greg. Cocconeis diaphana var. β is considered to be a synonym of C. dirupta and C. molesta var. crucifera is considered to be a synonym of C. molesta. Lectotypes are designated for C. diaphana and C. dirupta.
Diversity and distribution of adeonid bryozoans (Cheilostomata: Adeonidae) in Japanese waters
(2016)
Adeonid bryozoans construct antler-like erect colonies and are common in bryozoan assemblages along the Japanese Pacific coast. The taxonomy of Japanese adeonid species, however, has not been studied since their original descriptions more than 100 years ago. In the present study, adeonid specimens from historical collections and material recently collected along the Japanese coast are examined. Eight adeonid species in two genera were detected, of which Adeonella jahanai sp. nov., Adeonellopsis parvirostrum sp. nov., and Adeonellopsis toyoshioae sp. nov. are described as new species based on the branch width, size and morphology of frontal or suboral avicularia, shape and size of areolar pores, and size of the spiramen. Adeonellopsis arculifera (Canu & Bassler, 1929) is a new record for Japan. Lectotypes for Adeonellopsis japonica (Ortmann, 1890) and Adeonella sparassis (Ortmann, 1890) were selected among Ortmann’s syntypes. Most species of Adeonellopsis around Japan have a southern distribution from Sagami Bay to Okinawa, while A. japonica shows a more northern distribution from Kouchi to Otsuchi. In contrast, Adeonellopsis arculifera was collected only from southwestern Japan. A key to Japanese adeonid species is provided.
A survey of the camerobiid mites living on epiphytic bromeliads and the forest floor of a Mexican tropical dry forest was carried out. We found three new species of the genus Neophyllobius, which are described in this paper; the first two, namely N. cibyci sp. nov. and N. tepoztlanensis sp. nov., were both found inhabiting bromeliads (Tillandsia spp.) and living on two tree species (Quercus obtusata and Sapium macrocarpum); the third, N. tescalicola sp. nov., was found in soil and litter under Q. obtusata. These three new species can be differentiated from other species in the genus by a combination of morphological characters in adult females, mainly those setae on femora and genua I. The idiosoma and leg setal ontogeny of a camerobiid mite is presented for the first time in this paper, illustrating chaetotaxic notations and their relative positions in N. cibyci sp. nov. larva, protonymph and adults (female and male), and establishing setal homologies among instars. Setal homology with other species in the cohort Raphignathina is briefly discussed. Additionally, a compilation and an identification key to all known species of camerobiid mites in Mexico is provided.
Two new species of Tetrastigma from Thailand, T. calcicola Kochaiph. & Trias-Blasi sp. nov. and T. jaichagunii C.L.Li ex Kochaiph. & Trias-Blasi sp. nov. are described and illustrated. Tetrastigma calcicola sp. nov. is a slender climber restricted to the open areas on limestone mountains at high elevation in the northern part of Thailand. The other species, T. jaichagunii sp. nov., is similar to T. harmandii Planch., but differs from it by having more densely verrucose young branches, broader leaflets, 4-lobed thick discs, bigger globose berries and oblongoid seeds. This species occurs along streams or in forest margins in evergreen forest and it is widely distributed in several parts of Thailand.
This dissertation discusses the mutual influence between leaders and followers on perception, emotion and behavior, using an attachment theory perspective. Some individuals are more likely to be seen as leaders than others. On the one hand this is determined by the characteristics or attributes as well as skills of the person in question. However, on the other hand, followers’ perception and expectations play a big role as well, in particular which expectations of an ideal leader can be fulfilled by followers’ current leader. Although attachment theory and – styles have only recently entered the organizational psychology literature, this dissertation advances that literature by looking at the role of attachment orientations between leaders and followers. In doing so, this dissertation answers several recent research calls on this topic. The three main subsequent chapters discuss the predictive role of attachment orientations with regard to leader preferences, the transference of behavioural expectations from one leader to another, and the perception of leader prototypicality in groups. The first chapter discusses the connection between implicit leader preferences and attachment orientations as predictors. Results show that avoidant attached individuals prefer a more autonomous and independent leadership style, whereas anxious attached individuals prefer a supportive and team-oriented leadership style. In the second chapter I study the transference of behavioural expectations from one leader to another. Results show that avoidant attached individuals are more likely to engage in this transference process. In addition, I discuss and empirically test the influence of culture with regard to leader transference. In the final chapter, I examine the behavioural influence of attachment orientations on how likely someone is perceived to be a leader in groups. Based on 57 project groups, I find that team members actually perceive avoidant attached individuals to be the most leader-like. Put differently, given certain environmental conditions, insecure attachment orientations can be perceived as leaders. These results show that it is even more important that leaders somewhat adapt to their followers’ preferences and not commit to merely one particular leadership style.
Cells within a tissue form highly complex, cellular interactions. This architecture is lost in two-dimensional (2D) cell cultures. To close the gap between 2D cell cultures and in vivo tissues, three-dimensional (3D) cell cultures such as spheroids or embryoid bodies were developed. To fully take advantage of the third dimension, imaging techniques are essential. The emerging field of "image-based systems biology" exploits the information in images and builds a connection between experimental and theoretical investigation of biological processes. Such interdisciplinary approaches strongly depend on the development of protocols to establish 3D cell cultures, innovations in sample preparation, well-suited imaging techniques and quantitative segmentation methods.
Although 3D cell cultures and image-based systems biology provide a great potential, 2D methods are still not completely replaced by 3D methods. This is mainly due to methodical and technical hurdles. Therefore, this thesis provides a significant contribution to overcome these hurdles and to further develop 3D cell cultures. I established computational and experimental methods related to 3D aggregates and investigated fundamental, cellular processes such as adhesion, growth and differentiation.
The automatic segmentation method "PAS" and "LoS" were developed in the context of this thesis. They extract essential biological properties such as the projected area or features of cell nuclei from 2D or 3D images of 3D aggregates. Both algorithms show their accuracy robustly over image data from different samples and different microscopes. In addition, the superior performance of PAS and LoS was proven in a comparison with state-of-the-art methods.
The PAS approach served as an essential basis for investigating cellular processes such as adhesion and growth which are tightly regulated to contribute to tissue integrity. These processes are involved in the formation of spheroids. The temporally resolved data of spheroid formation of three mammary epithelial cell lines revealed differences in their formation dynamics as well as in the onset of spheroid formation phases (aggregation, compaction and growth). Despite these differences, adhesion- and growth-associated proteins such as E-cadherin, actin, microtubules, and the focal adhesion kinase show similar importance in a particular phase. Notably, certain proteins (e.g. E-Cadherin) contribute differently to spheroid formation of cells from different cell types in terms of cell adhesion and growth. Overall, analyses of the individual phases of spheroid formation revealed the temporal coordination of fundamental tissue-specific processes. The results contribute to a better understanding of the maintenance and disruption of tissue integrity.
An important but yet unknown process is how cells accomplish to arrange themselves against the gravitational force to form a spheroid. Live imaging with light sheet-based microscopy provides the best solution for a temporally and in particular spatially resolved investigation of spheroid formation. Although the imaging possibilities increase with this particular microscopy technique, available sample preparation methods are rare. Therefore, I have significantly optimized "agarose beaker" as preparation method for 3D long-term imaging of spheroid formation. The data show that upward movement of the cells takes place early. This movement is initiated in the centre of the initially flat cell layer. Subsequently, the cells move from the periphery of the cell layer toward the centre. Cells rearrange within the spheroid which is followed by growth. It is very likely that 3D aggregates form by adopting an energetically favoured, spherical shape by increasing cell-cell or cell-matrix contacts.
Besides the knowledge gained from the examination of the self-assembly process in different contexts, fully formed cellular aggregates can serve as basis to investigate differentiation processes. Differentiation guide cell fate specification during early embryonic development (i.e. preimplantation) and is not fully understood yet. Due to the lack of an in vitro system for preimplantation, I have developed "blastoids". These are 3D multicellular aggregates of mouse embryonic stem cells which represent important phases of preimplantation and beyond. In qualitative and quantitative analyses, a strong similarity was proven between blastoids and the inner cell mass of in vivo mouse embryos. Further results strongly suggest that both, the cell number and the trophectoderm play a subordinate role for cell fate decision during preimplantation. Furthermore, 3D neighbourhood analyses have shown that both, blastoids and mouse embryos, do not show a random "salt-and-pepper" pattern during differentiation. Instead, they show a yet unknown local clustering of cells with identical fates, suggesting local cell interactions that influence cell fate decision. Furthermore, the data indicate that the maturation of the epiblast in the later stages of preimplantation is initiated by an interaction between cells of the epiblast and the primitive endoderm.
Using image-based systems biology, I have investigated fundamental cellular processes such as adhesion, growth and differentiation in the context of tissue integrity and early embryonic development using 3D cellular aggregates. This highly interdisciplinary work is a major contribution to 3D cell biology and demonstrates how cells bind and interact within a complex system. The main methods developed in this thesis as well as the biological findings can be used not only in further biological but also in medical and pharmacological studies. They have the potential to advance our understanding of complex biological systems and to provide new opportunities for practical applications.
New leaf- and litter-dwelling species of the genus Pholcus from Southeast Asia (Araneae, Pholcidae)
(2016)
We describe eight new species of the genus Pholcus, and document their microhabitats. Four species are assigned to the previously described Pholcus ethagala group: P. tanahrata Huber sp. nov., P. uludong Huber sp. nov., and P. bukittimah Huber sp. nov. from the Malay Peninsula, and P. barisan Huber sp. nov. from Sumatra. These species are all litter-dwellers that build domed sheet webs on the undersides of large dead leaves on the ground. The other four species are assigned to newly created species groups: the P. tambunan group with two species from northern Borneo: P. tambunan Huber sp. nov. and P. bario Huber sp. nov.; and the P. domingo group with two species from the Philippines, Mindanao: P. domingo Huber sp. nov. and P. matutum Huber sp. nov. These latter four species are leafdwellers that build barely visible silk platforms tightly attached to the undersides of live leaves. The main rationale for this paper is to provide part of the taxonomic and natural history background for upcoming phylogenetic and evolutionary (microhabitat shifts) analyses.
The Thyropygus opinatus subgroup (Diplopoda: Harpagophoridae) of the T. allevatus group in Thailand is revised. Based on a phylogenetic analysis of mtDNA sequence data, it is merged with the T. bifurcus subgroup to form an extended T. opinatus subgroup. Nine new species are described: Thyropygus cimi sp. nov. and T. forceps sp. nov. from Nakhonsrithammarat Province, T. culter sp. nov., T. planispina sp. nov., T. undulatus sp. nov. and T. ursus sp. nov. from Krabi Province, T. mesocristatus sp. nov. from Songkhla Province, T. navychula sp. nov. from Phang-Nga Province and T. sutchariti sp. nov. from Phetchaburi Province.
The new subgenus Maculergithus subgen. nov. is established to accommodate two new species of the genus Gergithus Stål, 1870 (Issinae, Hemisphaeriini): G. (Maculergithus) tamdao subgen. et sp. nov. and G. (Maculergithus) luteomaculatus subgen. et sp. nov. from Tam Dao National Park in North Vietnam. Two more species from Hainan, China, G. multipunctatus Che, Zhang & Wang, 2007 and G. nonomaculatus Meng & Wang, 2012 are also placed in Maculergithus subgen. nov. A fifth species from Hainan, yet undescribed and erroneously identified as G. multipunctatus in recent papers also belongs to this new subgenus. Illustrations of habitus, morphological details and male genitalia together with a distribution map and an identification key to the species of Maculergithus subgen. nov. are provided. Four species of the genus Gergithus are now recorded in Vietnam. A rectificative note on the misinterpretation of G. multipunctatus in recent publications on Issidae is also provided.
Two new species of the genus Chrysotus Meigen, 1824 are described: Ch. masunagai Negrobov, Kumazawa, Tago sp. nov and Ch. saigusai Negrobov, Kumazawa & Tago sp. nov. Chrysotus parilis Parent, 1926 is recorded from Japan for the first time. An identification key to all known species of the genus Chrysotus of Japan is presented together with a tree diagram showing relationships among them.
Brooksia lacromae sp. nov. is described from zooplankton material collected at a marine monitoring station in the South Adriatic in the autumn of 2014. The description of both solitary and aggregate forms is given along with 18S rRNA and mitochondrial cox1 sequence data that provides strong evidence that both forms belong to the same species. The described species is morphologically markedly different from B. rostrata (Traustedt, 1893) and B. berneri van Soest, 1975, previously the only two species in the genus Brooksia. Genetic analysis based on 18S rRNA gene confirmed distinctness of B. lacromae sp. nov. from B. rostrata (1.5% uncorrected pairwise distance). The appendicularian Fritillaria helenae Bückmann, 1924, so far known from the Atlantic only, was found in the same samples as B. lacromae sp. nov. Co-occurrence of B. lacromae sp. nov. with an Atlantic appendicularian suggests an Atlantic or Western Mediterranean origin for this new taxon.
Chlorine monoxide (ClO) plays a key role in stratospheric ozone loss processes at midlatitudes. We present two balloon-borne in situ measurements of ClO conducted in northern hemisphere midlatitudes during the period of the maximum of total inorganic chlorine loading in the atmosphere. Both ClO measurements were conducted on board the TRIPLE balloon payload, launched in November 1996 in León, Spain, and in May 1999 in Aire sur l'Adour, France. For both flights a ClO daylight and night-time vertical profile was derived over an altitude range of approximately 15-35 km. ClO mixing ratios are compared to model simulations performed with the photochemical box model version of the Chemical Lagrangian Model of the Stratosphere (CLaMS). Simulations along 24-hour backward trajectories were performed to study the diurnal variation of ClO in the midlatitude lower stratosphere. Model simulations for the flight launched in Aire sur l'Adour 1999 show an excellent agreement with the ClO measurements. For the flight launched in León 1996, an overall good agreement is found, whereas the flight is characterized by a more complex dynamical situation due to a possible mixture of vortex and non-vortex air. We note that for both flights at solar zenith angles greater than 86°-87° simulated ClO mixing ratios are higher than observed ClO mixing ratios. However, the present findings indicate that no substantial uncertainties exist in midlatitude chlorine chemistry of the stratosphere.
Acute myeloid leukemia (AML) is a clonal malignancy of hematopoietic stem cells (HSCs) characterized by expansion of myeloid blasts in the bone marrow. It has been shown that autophagy is a degradative process, which delivers cytoplasmic components to lysosomes to prevent malignant transformation by maintaining HSC integrity. Besides its function as a bulk degradation machinery to recycle cytoplasmic components during limited energy supply, autophagy also serves as an intracellular quality control mechanism. Selective autophagy requires autophagy receptors such as p62 to specifically bridge the targeted cargos into autophagosomes. p62 is known as a central signaling hub involved in pro-oncogenic signaling pathways and autophagic degradation pathways. However, little is known about the role of p62 as a selective autophagy receptor in AML. This study aims to elucidate the precise function of p62 as an autophagy receptor in leukemia development and maintenance.
In silico analysis revealed that high p62 expression was significantly associated with poor overall survival of adult patients with de novo AML, suggesting that p62 may promote leukemia maintenance. To address the functional role of p62 in leukemia, genome editing by CRISPR/Cas9 was used to knockout p62 in four human AML cell lines. Importantly, p62 loss reduced cell proliferation in all four cell lines. This observation could be transferred to a murine leukemia cell model in which leukemic transformation of lineage-depleted bone marrow (ldMBM) cells was induced by overexpression of the human transcriptional coactivator MN1. Knockdown of p62 by shRNA in MN1-driven leukemia cells impaired proliferation and decreased colony forming ability without altering apoptosis. This indicates that p62 is crucial for leukemia proliferation in vitro. To further characterize the role of p62 in leukemia development and maintenance a murine AML transplantation model was established. Therefore, ldMBM cells isolated from WT and p62-/- mice were transduced with MN1 and transplanted into lethally irradiated mice. As expected, all mice developed fatal myeloid proliferation. Notably, p62 loss in MN1-driven leukemia significantly prolonged survival in mice and caused a more immature phenotype. Consistent with the in vitro results, ex vivo analysis of p62-/- leukemic cells displayed decreased colony-forming ability, although p62 loss did not affect composition and function of HSCs. Moreover, re-transplantation of primary MN1-driven leukemia cells attenuated leukemia progression upon p62 loss. These findings support a decisive role of p62 in leukemia development and maintenance.
To gain molecular insight into the function of p62 during myeloid transformation an interactome analysis of murine MN1-driven leukemia cells was performed. This revealed first that p62 predominantly interacts with mitochondrial proteins and second that inhibition of autophagic degradation causes accumulation of p62-bound mitochondria. This leads to the first assumption that loss of p62 may provoke mitochondrial accumulation with increasing mitochondrial damage and second that p62 may mediate degradation of mitochondria by mitophagy. Indeed, in the absence of p62, accumulation of dysfunctional mitochondria was detected by morphological changes of the mitochondria, increased mitochondrial ROS and impaired mitochondrial respiration capacity. Furthermore, induction of PINK1/Parkin-independent mitophagy revealed that loss of p62 caused impaired degradation of mitochondrial proteins and reduced translocation of damaged mitochondria into autophagosomes. Taken together, p62 is required for effective degradation of dysfunctional mitochondria by mitophagy in AML.
Due to the fact that p62 is a multifunctional protein, rescue experiments with different mutants of p62 were performed to clarify if p62-mediated mitophagy contributes to leukemia proliferation. Notably, the autophagy-deficient mutant (disabled to bind autophagosomes) reduced cell growth and colony-forming ability to the same extent as knockdown of p62, as the clustering-deficient mutant (disabled to form aggregates) displayed an intermediate phenotype. Strikingly, only the autophagy-deficient mutant failed to rescue mitophagy.
In conclusion, this study demonstrates the prominent role of p62 as a selective autophagy receptor for mitochondrial quality control which contributes to leukemia development and maintenance. Therefore, targeting selective autophagy opens new venues in the treatment of AML.
Funktionsverbgefüge im Deutschen und Türkischen : eine Analyse in ausgewählten Zeitungstexten
(2017)
Der vorliegende Artikel beschäftigt sich mit der Untersuchung von Funktionsverbgefügen (FVG) in deutschen und türkischen Zeitungstexten im Rahmen der kontrastiven Linguistik. Die FVG, welche aus einem Funktionsverb und einem Substantiv bestehen, werden im Deutschen als eine grammatische Kategorie abgehandelt. Die für deutsche Sprache entwickelten Kriterien werden ins Türkische adaptiert. Es wurde festgestellt, dass FVG bzw. die Substantiv-Verb Verbindungen in beiden Sprachen hinsichtlich der morphologischen, syntaktischen und semantischen Kriterien über gemeinsame Merkmale verfügen. Da diese Strukturen meistens in der Schriftsprache verwendet werden, werden sie in dieser Arbeit in Zeitungstexten untersucht. Am Ende dieser Untersuchung wurde festgestellt, dass die betreffende Struktur in beiden Sprachen Anwendung findet und ähnliche Merkmale hat. Auch stellte sich heraus, dass die präpositionalen Strukturen im Deutschen mehr Anwendung finden, während im Türkischen Substantiv im Akkusativ mehr gebraucht wird.
Kasseler Apoll und Dresdener Schauspielerrelief : Margarete Bieber und die Gießener Antikensammlung
(2007)
Vor 100 Jahren wurde Margarete Bieber 1907 in Bonn mit einer Arbeit über "Das Dresdner Schauspielerrelief" im Fach Klassische Archäologie promoviert. Besaß dieser Schritt als Frau an den preußischen Universitäten zu dieser Zeit noch eine hohe Seltenheit (und hatte erheblicher Anstrengungen bedurft), so war ihre Habilitation 1919 an der Landesuniversität in Gießen eine Sensation; Margarete Biebers Rolle für die Geschichte des Frauenstudiums und ihre Vorreiterrolle in der Klassischen Archäologie, aber auch ihre Bedeutung für die Universität Gießen ist daher in jüngerer Zeit auch vielfach gewürdigt worden. ...
Als Schenkung des im September 2006 in den Ruhestand getretenen Archäologen und vormaligen Gießener Lehrstuhlinhabers, Professor Dr. Wolfram Martini, ist eine kleine, figürlich bemalte Scherbe in die Antikensammlung der Justus Liebig-Universität gelangt, die auf den ersten Blick unbedeutend und wenig interessant zu sein scheint, sich bei näherer Betrachtung aber als sehr instruktiv erweist und den bisherigen Bestand antiker Keramik trotz ihrer geringen Größe und Erhaltung unter verschiedenen Aspekten vortrefflich ergänzt, weshalb sie im Folgenden ausführlicher vorgestellt werden soll. ...
Im Rahmen eines museumsdidaktischen Seminars unter Leitung von Dr. Matthias Recke wurde im Sommersemester 2005 die Ausstellung der Antikensammlung im Wallenfels’schen Haus neu konzipiert. Dabei wurde neben einer didaktisch durchdachten Aufstellung, die den Besucher eine geographische Rundreise um das Mittelmeer erleben lässt und die von Ägypten über die Levante, Zypern und Kleinasien bis nach Griechenland und Italien führt, vor allem auf eine korrekte und prägnante Beschriftung der ausgestellten Objekte Wert gelegt. ...
Im Berichtsjahr fanden vier Sonderausstellungen in der Antikensammlung statt. Verbunden mit der Vorstellung der Neuerwerbungen wurde am 28. Oktober 2009 die Ausstellung "PAN-tastisch! HAP Grieshaber und die Antike" eröffnet. Obwohl Grieshaber (1909-1981), der zu den bedeutendsten deutschen Künstler der Nachkriegszeit zählt, anlässlich seines 100. Geburtstages im Jahre 2009 mit einer Vielzahl von Werkschauen geehrt wurde, nahm die Veranstaltung in Gießen eine herausragende Stellung ein. Erstmals wurde das Verhältnis von Grieshaber zur Antike thematisiert und in einer eigenständigen Publikation umfassend gewürdigt. In der Gegenüberstellung mit Kunstwerken der Antikensammlung wurden diese Bezüge besonders deutlich. ...
Fractional release factors of long-lived halogenated organic compounds in the tropical stratosphere
(2009)
Fractional release factors (FRFs) of organic trace gases are time-independent quantities that influence the calculation of Global Warming Potentials and Ozone Depletion Potentials. We present the first set of vertically resolved FRFs for 15 long-lived halo carbons in the tropical stratosphere up to 34 km altitude. They were calculated from measurements on air samples collected on board balloons and a high altitude aircraft. We compare the derived dependencies of FRFs on the mean stratospheric transit times (the so-called mean ages of air) with similarly derived FRFs originating from measurements at higher latitudes and find significant differences. Moreover a comparison with averaged FRFs currently used by the World Meteorological Organisation revealed the latter to be imprecise measures due to their observed vertical and latitudinal variability. The presented data set could thus be used to improve future ozone level and climate projections.
The Indochinese to southern Chinese millipede genus Tylopus currently comprises 62 species, including eight new ones: T. flavolineatus sp. nov., T. hongkhraiensis sp. nov. from central and northern Thailand, respectively, T. moniliformis sp. nov., T. retusus sp. nov., T. acuminatus sp. nov., T. dorsalis sp. nov., T. thunghaihin sp. nov., all from Laos, and T. punctus sp. nov. from northern Myanmar. A new record of T. baenzigeri Golovatch & Enghoff, 1993, from northern Thailand is given. All these species are richly illustrated, and a modified key to all known species of the genus is also provided.
When based on phylogenetic proposals, biogeographic historic narratives have a great interest for hypothesizing paths of origin of the current biodiversity. Among the many questions that remain unsolved about psocids, the distribution of Thyrsophorini represents still a remarkable enigma. This tribe had been considered as exclusively Neotropical, until the description of Thyrsopsocopsis thorntoni Mockford, 2004, from Vietnam. Three hypotheses have been proposed to explain this atypical distribution, recurring to dispersal, vicariance and morphological parallelism between lineages, but the lack of evidence has not allowed a unique support. Here, we describe a new Neotropical species of Thyrsopsocopsis, and also attempt to test the three biogeographical hypotheses in a phylogenetic context. In our analyses, the position of Cycetes (Cycetini) and Thyrsopsocopsis among Thyrsophorini psocids is well resolved, suggesting a dispersal event from the Neotropics for both genera.
The variability of the reticulum pattern, ornamentation and outline of the Urocythereis populations of the La Strea Bay is analysed. The results show that the shell features of the form U. distinguenda (Neviani, 1928) (= U. oblonga Brady, 1866) have to be included within the high variability range of U. margaritifera (G.W. Müller, 1894). Consequently, it is suggested that in the upper infralittoral waters of the inlet two (and not three, as stated in previous investigations) species of the genus Urocythereis presently live. A second form, displaying a relatively low variability, is described as a new species, U. ilariae sp. nov.
Three new species of Monepidosis Mamaev, 1966, a Holarctic genus of Porricondylinae (Diptera, Cecidomyiidae), are described: M. heterocera sp. nov. from Sweden and Germany, M. scepteroides sp. nov. from Sweden, and M. shikokuensis sp. nov. from Japan. A new porricondyline genus, Antipodosis gen. nov., is introduced for eight new species from New Zealand, named A. australis gen. et sp. nov., A. elongata gen. et sp. nov., A. granvillensis gen. et sp. nov., A. pureora gen. et sp. nov., A. rakiura gen. et sp. nov., A. rotoiti gen. et sp. nov., A. rotoroa gen. et sp. nov., and A. waipapa gen. et sp. nov. Male genitalic morphology indicates that Monepidosis and Antipodosis gen. nov. are closely related, together forming the Monepidosis group of genera, which stands out from the other Porricondylini. Monepidosis spatulata Spungis, 2006, a species originally described from Latvia and Lithuania, is for the first time reported to occur in Sweden.
Generally, “ophrys-related” scuticociliates belong to a specialised group of ciliated protozoa that may act as commensals or pathogens of fishes and crustaceans. In the present study, four “ophrystaxa” scuticociliates, i.e., Paramesanophrys typica gen. et sp. nov., Mesanophrys carcini (Grolière & Léglise, 1977) Small & Lynn in Aescht, 2001, Metanophrys sinensis Song & Wilbert, 2000, and Metanophrys similis Song et al., 2002, were collected from Chinese coastal waters or mariculture ponds and investigated. Paramesanophrys gen. nov. is assigned to the family Orchitophryidae and differs from its other genera mainly by the position of the paroral membrane relative to membranelle 1–3, i.e., the membrane extends anteriorly to the posterior end of membranelle 3. The type species P. typica gen. et sp. nov., is defined by an elongated body with the posterior end depressed where the caudal cilium is located; 20 or 21 somatic kineties; double-rowed membranelle 1 with eight to ten basal bodies in each kinety; irregularly multi-rowed membranelle 2 and membranelle 3; scutica comprising c. seven or eight kinetosome pairs; a single macronuclear nodule; and marine habitat. The redescription of the three previously known species can be summarized as follows: 1) improved diagnosis is provided for Metanophrys sinensis Song & Wilbert, 2000 based on the original description and the present study; 2) some population-dependent characteristics of our new Mesanophrys carcini isolate are presented; 3) Metanophrys similis, collected from the South China Sea, resembles the original Qingdao population.
The Southeast Asian Pholcus halabala species group is revised and re-delimited, based mainly on field observations (life color pattern, web design, position of egg-sac when carried by female, microhabitat) and ultrastructure (silk spigots, modifications of male cheliceral apophyses). The core group includes six leafdwelling species that have distinctive color patterns in life specimens (black and white or yellowish abdominal marks, dark pattern on posterior half of carapace) and build round to oval silk platforms on the undersides of leaves. Seven further species are tentatively assigned to the group pending further study. Several species originally assigned to the Pholcus halabala group are transferred to three newly proposed species groups, the Ph. krabi, Ph. buatong, and Ph. andulau groups. Nine species are newly described, four in the Ph. halabala group (Ph. khaolek Huber, sp. nov.; Ph. kuhapimuk Huber, sp. nov.; Ph. lintang Huber, sp. nov.; Ph. ubin Huber, sp. nov.); three in the Ph. krabi group (Ph. kipungit Huber, sp. nov.; Ph. krabi Huber, sp. nov.; Ph. narathiwat Huber, sp. nov.); one in the Ph. buatong group (Ph. buatong Huber, sp. nov.); and one in the Ph. andulau group (Ph. lambir Huber, sp. nov.). The females of Ph. satun Huber, 2011 and Ph. schwendingeri Huber, 2011 (both members of the buatong group) are newly described.
A new genus and species of bostrichid beetle, Octomeristes gen. nov. and Octomeristes pusillus gen. et sp. nov., in the tribe Xyloperthini is described from litchi (Litchi chinensis Sonn.) wood in Thailand. The genus is compared to Octodesmus Lesne, 1901, the only other xyloperthine genus with eight-segmented antennae, and to the xyloperthine genera, Xylion Lesne, 1901, Xylionulus Lesne, 1901 and Xylobosca Lesne, 1901. A new combination, Octomeristes minutissimus (Lesne, 1932) comb. nov., is transferred from Octodesmus Lesne, 1901. A lectotype is designated for Octodesmus episternalis Lesne, 1901, the type species of Octodesmus. Octodesmus kamoli Chûjô, 1964 is designated a new synonym of Paraxylion bifer (Lesne, 1932). A key is provided to the species of Octodesmus and Octomeristes gen. nov.
Two new alcyonacean-associated species, Hamodactylus paraqabai sp. nov. from Papua New Guinea and the Great Barrier Reef and H. pseudaqabai sp. nov. from Indonesia and Malaysia, are described and illustrated. To evaluate the status of the new species and their relationship within the genus Hamodactylus Holthuis, 1952, we combined morphology and phylogenetic analyses based on the cytochrome c oxidase subunit I (COI) mitochondrial gene. Both new species are closely related, with their mutual genetic divergence reaching 3-4%. They are further most related to Hamodactylus aqabai Bruce & Svoboda, 1983, originally described from the Red Sea. Both new species are distinguished from all other congeners by the presence of multiple teeth distally on the cutting edges of the fingers of the first pereiopods, and, in the case of H. paraqabai sp. nov., by a full reduction of the fixed finger on the second pereiopod chela. In H. pseudaqabai sp. nov. the finger is greatly reduced to a small but distinct stub, and the telson bears only a single pair of dorsal spines, as in H. aqabai. A key for the identification of all six currently known species is proposed.
The nine British and Irish species of Enicospilus are revised, mapped and an identification key provided. One species, Enicospilus myricae sp. nov., is described as new; Enicospilus merdarius (Gravenhorst, 1829) is a senior synonym of E. tournieri (Vollenhoven, 1879) syn. nov.; the only available name for E. merdarius auctt. is Enicospilus adustus (Haller, 1885) stat. rev., and a neotype is designated for Ophion adustus Haller, 1885. Enicospilus cerebrator Aubert, 1969 and E. repentinus (Holmgren, 1860) are newly recorded from Britain. Some host data are available for eight of the nine species.
Two small, ground and litter-dwelling pholcid species from northern Borneo are described as representatives of a new genus, Hantu gen. nov.: H. kapit gen. et sp. nov. and H. niah gen. et sp. nov. Previous cladistic analyses suggested a closer relationship with the genera Savarna Huber, 2005 and Khorata Huber, 2005 (mainland Southeast Asia) than with the geographically closer genus Aetana Huber, 2005 (Borneo and Philippines to Fiji). Since the two species do not share any of the synapomorphies of Khorata and Savarna while having several synapomorphies on their own (ventral apophysis on male palpal coxa; male palpal trochanter apophysis with small teeth or scales; spines on male femora 1; high density of vertical hairs on male femora; presence of scape on epigynum), they are here proposed as representing a new genus.
Taxonomic updates and descriptions of four new species from Yunnan, China are provided: three new species in the genus Pitambara Distant, 1906: P. triremiprocta Wang & Soulier-Perkins, sp. nov., P. impudica Wang & Bourgoin, sp. nov., P. tricorne Wang & Wang, sp. nov., and one new species in the genus Serida Walker, 1857: Serida parenthesisflexuosa Wang & Soulier-Perkins, sp. nov. A new identification key to Pitambara species is provided, as well as to the species of the genus Lacusa Stål, 1862. Lacusa yunnanensis Chou & Huang, 1985 stat. rev. is not considered as a synonym of the species L. fuscofasciata (Stål, 1854) anymore and Lacusa orientalis (Liang, 2000) is transferred to the genus Acothrura Melichar, 1915 as Acothrura orientalis (Liang, 2000) comb. nov.
We revise the Panjange nigrifrons group in Borneo and document an unexpected diversity in western Sarawak forests. Five species occur within 80 km from Kuching, each species being known from its type locality only. Further species occur east until Niah, but the genus seems to be absent from Sabah. We contrast this with another pholcid genus (Aetana Huber, 2005), which is diverse in Sabah and westward until Niah, but does not seem to occur in central and western Sarawak. Five species are newly described: Panjange kapit Huber, sp. nov., Panjange kubah Huber, sp. nov., Panjange niah Huber, sp. nov., Panjange pueh Huber, sp. nov., Panjange seowi Huber, sp. nov.; Panjange tahai (Huber, 2011) comb. nov. is transferred from Pholcus.
An updated classification of Polyalthia in Peninsular Malaysia is presented. A synopsis (listing of species with synonymy and typification, and keys to species) is presented for the genera Huberantha, Maasia, Monoon and Polyalthia sensu stricto. One new species (Polyalthia pakdin I.M.Turner & Utteridge sp. nov.) is described and a conservation assessment presented for it. Monoon xanthopetalum Merr. represents a new record for Peninsular Malaysia. Six new lectotypes are designated.
Two new species of potamonautid freshwater crabs are described from the Imatong Mountains and Mount Moroto in northern Uganda, East Africa, and a third highland species, Potamonautes amalerensis (Rathbun, 1935) stat. rev. from Mount Kadam is re-diagnosed based on examination of the holotype. All three species are endemic to a different mountain range and their collection localities indicate a distinct preference for higher altitudes. Diagnoses, illustrations and distribution maps are provided for these taxa, and they are compared to similar species from the region. The conservation status of all three species is discussed.
A new genus in the tribe Issini (Hemiptera: Fulgoromorpha: Issidae) is described from South China: Orbita Meng & Wang, gen. nov., its type species Orbita parallelodroma Meng & Wang, gen. et sp. nov. (China: Fujian) is described and illustrated. In addition, one new species of Neokodaiana Yang, N. minensis sp. nov. is described and illustrated from the same locality as the new genus. A key to the genera of Issini from China and neighbouring countries is provided.
Epigraphic documents attest that the two neighbouring, inland sites, Idalion and Tamassos, were kingdoms during the Cypro-Archaic period, and that-within an interval of nearly a century - they were both incorporated by the kingdom of Kition during the Cypro-Classical period, thereby losing their independent status. The geographical position of Idalion and Tamassos must have been both a blessing and a curse: while the two polities could thrive on the exploitation of the nearby copper mines, they also had to withstand the economic interest of other Cypriote polities in these natural resources. In addition, we may assume that, because of their inland position, Idalion and Tamassos were forced to seek economic collaboration with polities that had direct access to the sea for the export and exchange of commodities beyond the island. We may further expect that the control of ore-mining and forestry activities must have been a potential source of territorial strife between the two inland kingdoms. Therefore, the geo-economic reality likely induced Idalion and Tamassos to a dualistic relationship of being both allies and competitors. ...
Bees of the family Halictidae Thomson, 1869 from Dominica, Lesser Antilles (Hymenoptera: Apoidea)
(2016)
The bees of the family Halictidae Thomson, 1869 from Dominica are reviewed. Seven new species are described and illustrated: Lasioglossum (Dialictus) kalinago sp. nov., L. (D.) dominicense sp. nov., L. (D.) kilpatrickae sp. nov., L. (Habralictellus) roseauense sp. nov., Sphecodes diablotinus sp. nov., S. albifacies sp. nov. and Habralictus antillarus sp. nov. A description and images of the previously unknown female of Microsphecodes dominicanus (Stage, 1972) are provided. In total, eleven species are recognized: eight nest-building species and three kleptoparasites. All halictid species from Dominica are currently known only from the island. A key to halictid bees from Dominica is provided.
Der vorliegende Beitrag versucht, einen Überblick über die aktuelle Zypern-Archäologie in Deutschland zu geben. Neben einer Zusammenfassung der Ausgrabungen und Feldforschungen, insbesondere seit dem 2. Weltkrieg, wird der Schwerpunkt auf den deutschen Sammlungen und Museen liegen, die zyprische Antiken beherbergen. Sie können an dieser Stelle nicht im Detail vorgestellt werden, doch soll durch die wichtigsten Eckdaten ihrer Entstehung und Zusammensetzung nicht nur ein Bild der Kypriaka in öffentlichem Besitz, sondern auch ein Baustein zu einer Geschichte des Sammelns zyprischer Altertümer in Deutschland geliefert werden. Eine Zusammenstellung von zypern-relevanten Ausstellungen sowie von universitären Promotions- und Forschungsprojekten rundet die Übersicht ab.
The present work provides the first record of the genus Dinotrema Foerster, 1862 in the Neotropical region. Four new Neotropical species are described and illustrated: D. multiareolatum Peris-Felipo sp. nov., D. plaumanni Peris-Felipo sp. nov., D. subbidentatum Peris-Felipo sp. nov., and D. teutoniaense Peris-Felipo sp. nov. The following new combinations are suggested for Nearctic species: Dinotrema angusticornis (Fischer, 1969) comb. nov., D. armillariae (Fischer, 1969) comb. nov., D. bucculatricis (Fischer, 1969) comb. nov., D. caudatulum (Fischer, 1969) comb. nov., D. clayensis (Fischer, 1969) comb. nov., D. communis (Fischer, 1969) comb. nov., D. disstriae (Fischer,1969) comb. nov., D. pauperum (Fischer, 1969) comb. nov., D. saileri (Fischer, 1969) comb. nov., D. shannoni (Fischer, 1969) comb. nov. and D. sylvaticae (Fischer, 1969) comb. nov. An identifi cation key of the all New World Dinotrema species is provided.
In this study we analyze the calcarean sponge diversity of the Adriatic Sea, the type locality of some of the first described species of calcarean sponges. Morphological and molecular approaches are combined for the taxonomic identification. Our results reveal six species new to science and provisionally endemic to the Adriatic Sea (Ascandra spalatensis sp. nov., Borojevia croatica sp. nov., Leucandra falakra sp. nov., L. spinifera sp. nov., Paraleucilla dalmatica sp. nov., and Sycon ancora sp. nov.), one species previously known only from the Southwestern Atlantic (Clathrina conifera), and three already known from the Adriatic Sea (Ascaltis reticulum, Borojevia cerebrum, and Clathrina primordialis). We confirm the presence of the alien species Paraleucilla magna in the Adriatic and again record Clathrina blanca, C. clathrus, and C. rubra. We emend the description of the genus Ascaltis, propose a lectotype for Borojevia cerebrum and synonymise B. decipiens with B. cerebrum. A checklist of all calcarean species previously and currently known from the Adriatic Sea (39 species) is given. The Central Adriatic is indicated as the richest calcarean sponge fauna sector; however, the biodiversity of this class is underestimated in the whole Adriatic Sea and new systematic surveys are desirable.
The new genus Geotypodon gen. nov. is described. It includes two species from the Udzungwa Mountains: G. millemanus gen. et sp. nov. (type species) and G. submontanus gen. et sp. nov., one species from nearby Iringa: G. iringensis gen. et sp. nov., and 18 previously described species hitherto incorrectly assigned to Odontopyge Brandt, 1841.
Two species of Tomoceridae were found near Dalat, southern Vietnam. Tomocerus ocreatus Denis, 1948 is redescribed based on a neotype specimen. Previous records of Tomocerus ocreatus in non-type localities are reevaluated. A new species Tomocerina annamitica sp. nov. is described. The new species is mainly characterized by its small body size, pointed tenent hair, compound dental spines and the absence of intermediate teeth on mucro.
Two new species from South Africa, Dactylonotus nigricorpus sp. nov. and Dactylonotus tsitsikamma sp. nov., are described and illustrated. D. nigricorpus sp. nov. differs from all other species of the genus in the black body, the smaller size and the shorter antenna. D. tsitsikamma sp. nov. is peculiar in the genus in bearing a flag of long setae on the fifth segment of the fore tarsus. An identification key to 6 Afrotropical species of the genus is provided.
A new species of Fidelia Friese, 1899 is described from southern Africa: Fidelia (Fideliopsis) whiteheadi Litman & Kuhlmann sp. nov. Diagnostic characters are provided to distinguish this species from others in the genus, particularly from the closely related F. hessei; an updated description for Fidelia hessei is also given. The host plant preferences and seasonal activity of F. whiteheadi Litman & Kuhlmann sp. nov. and F. hessei are discussed. Finally, a revised, illustrated key to species of the genus Fidelia is presented.
The genus Profundiconus Kuroda, 1956 is reviewed. The morphological characters of the shell, radular tooth and internal anatomy of species in Profundiconus are discussed. In particular, we studied Profundiconus material collected by dredging in deep water during different scientific campaigns carried out in the Solomon Islands, Madagascar, Papua New Guinea and New Caledonia. We reconstructed a phylogeny of 55 individuals based on partial mitochondrial cox1 gene sequences. The phylogeny shows several clades containing individuals that do not match any of the known species of Profundiconus based on their shell and radular morphologies, and are introduced here as five new species: Profundiconus maribelae sp. nov. from the Solomon Islands; P. virginiae sp. nov. from Chesterfield Plateau (New Caledonia); P. barazeri sp. nov. from Chesterfield Plateau and the Grand Passage area (New Caledonia); P. puillandrei sp. nov. from Norfolk Ridge (New Caledonia), Kermadec Ridge (New Zealand) and possibly Balut Island (Philippines); and P. neocaledonicus sp. nov. from New Caledonia. Furthermore, Profundiconus teramachii forma neotorquatus (da Motta, 1984) is raised to specific status as P. neotorquatus (da Motta, 1984).
New species of “giant” plume moths of the genus Platyptilia (Lepidoptera, Pterophoridae) from Uganda
(2016)
This paper describes two new species of plume moths from the group of the so-called “giant” Platyptilia Hubner, 1825: Platyptilia fletcheri Ustjuzhanin & Kovtunovich sp. nov. and P. stanleyi Ustjuzhanin & Kovtunovich sp. nov. Both species were collected in the Rwenzori Mountains in Uganda and Rwanda, respectively. Platyptilia stanleyi Ustjuzhanin & Kovtunovich sp. nov. exceeds all the known African species of Pterophoridae in its wingspan of 49 mm.
Two new species of the genus Sectonema from natural habitats of northern Vietnam are studied. This paper includes their descriptions, measurements, line illustrations, and light microscope (LM) and scanning electron microscope (SEM) pictures. Sectonema tropicum sp. nov. is characterized by a 2.56– 3.24 mm long body, 19–21 μm broad lip region, odontostyle 20–21 μm long at its ventral side, 730– 834 μm long neck, pharyngeal expansion occupying 52–59% of total neck length, uterus a simple tube-like structure 150–242 μm long or 1.2–2.5 times the body diameter, pars refringens vaginae present, V = 48–52, short (31–40 μm, c = 70–91, c’ = 0.5–0.6) and rounded tail, 91–97 μm long spicules, and only one weakly developed ventromedian supplement. Sectonema vietnamense sp. nov. is characterized by its slender (a = 33–49) and 2.71–4.25 mm long body, 14–16 μm broad lip region, odontostyle 8–9 μm long at its ventral side, 716–918 μm long neck, pharyngeal expansion occupying 63–67% of total neck length, uterus simple and 209–242 μm long or 2.5–2.9 times the corresponding body diameter, pars refringens vaginae absent, V = 54, short (34–39 μm, c = 70–115, c’ = 0.6–0.8) and rounded tail, 59–75 μm long spicules, and three or four irregularly spaced ventromedian supplements bearing hiatus. Both species are also characterized by their nearly continuous lip region, an atypical feature in this genus. Molecular analysis of S. tropicum sp. nov. confirms that Sectonema is a natural (monophyletic) taxon, very close to Metaporcelaimus.
The pyrrolobenzodiazepine tilivalline (1) was originally identified in the human gut pathobiont Klebsiella oxytoca, the causative agent of antibiotic-associated hemorrhagic colitis. Here we show the identification of tilivalline and analogs thereof in the entomopathogenic bacterium Xenorhabdus eapokensis as well as the identification of its biosynthesis gene cluster encoding a bimodular non-ribosomal peptide synthetase. Heterologous expression of both genes in E. coli resulted in the production of 1 and from mutasynthesis and precursor directed biosynthesis 11 new tilivalline analogs were identified in X. eapokensis. These results allowed the prediction of the tilivalline biosynthesis being similar to that in K. oxytoca.
The Lycocerus hanatanii species group is revised, with the addition of seven taxa: L. araticollis (Fairmaire, 1897), L. nigripennis (Pic, 1938), L. griseopubens (Pic, 1928), L. yitingi Hsiao & Okushima sp. nov., L. aurantiacus Hsiao & Okushima sp. nov., L. evangelium Hsiao & Okushima sp. nov. and L. kintaroi Hsiao & Okushima sp. nov. Supplementary descriptions of the males of L. araticollis and L. griseopubens are provided. Lycocerus nigripennis (Pic, 1938) and L. pictus (Wittmer, 1983) are redescribed in detail. Each species is provided with photos or illustrations of genitalia of both sexes and abdominal ventrite VII of the female if available. Distribution maps and a key to the species of the L. hanatanii species group are presented. In addition, the monophyly of the L. hanatanii species group is supported based on a morphological phylogenetic analysis.
We describe several new species of the previously monotypic Panjange lanthana species group from the Philippines and document their extraordinary morphology. Some species show strong male genital asymmetry, a phenomenon that seems to be exceedingly rare in spiders. Males of most species have eye stalks, and in two species these eye stalks are among the longest ever recorded in spiders. Some species show a tendency for male genital (pedipalp) elongation, and one species has the longest and thinnest palps ever recorded in Pholcidae. A cladistic analysis is performed including all described and several undescribed species of Panjange (except for one “problem species”), supporting the lanthana group and its close relationship with members of the possibly paraphyletic cavicola group. The following eight new species are described: Panjange malagos Huber sp. nov.; Pa. casaroro Huber sp. nov.; Pa. camiguin Huber sp. nov.; Pa. hamiguitan Huber sp. nov.; Pa. isarog Huber sp. nov.; Pa. dinagat Huber sp. nov.; Pa. marilog Huber sp. nov.; Pa. bukidnon Huber sp. nov.
This study deals with the biodiversity and distribution of cavernicolous Amphipoda in caves of the Arabika massif (Western Caucasus). The Sarma, Trojka and Orlinoe Gnezdo caves were explored during speleological expeditions over the years 2011–12. Two new species of Amphipoda were found: a sub-surface dweller Zenkevitchia sandroruffoi sp. nov. is reported from the Sarma, Trojka and Orlinoe Gnezdo caves at depths from -30 m to -350 m; the second one, a deep dweller Adaugammarus pilosus gen. et sp. nov. is reported from the Sarma Cave at depths of -1270 to -1700 m. Adaugammarus gen. nov. shares similarities with Typhlogammarus Schäferna, 1907 and Zenkevitchia Birstein, 1940. The species Anopogammarus birsteini Derzhavin, 1945 is also re-described herein based on new samples that suggest close affinity of this species with the family Gammaridae. The original taxonomic combination is resurrected for Zenkevitchia revazi Birstein & Ljovuschkin, 1970, comb. resurr. (from Anopogammarus Derzhavin, 1945). To accommodate morphologically different species in the genus Zenkevitchia, two new groups are proposed. These are the admirabilis-group (Z. admirabilis Birstein, 1940 and Z. yakovi Sidorov, 2015) and the sandroruffoi-group (Z. sandroruffoi sp. nov. and Z. revazi). An updated molecular (mt-cox1) phylogeny, an identification key to the genera and a distribution map for the typhlogammarid amphipod species of Transcaucasia are provided.
Fifteen new species of Begonia L. from Sumatra are described and illustrated, in Begonia sect. Bracteibegonia (B. beludruvenea M.Hughes sp. nov. and B. jackiana M.Hughes sp. nov.), B. sect. Petermannia (B. harauensis Girm. sp. nov.), B. sect. Platycentrum (B. leuserensis M.Hughes sp. nov.), B. sect. Reichenheimia (B. fl uvialis M.Hughes sp. nov., B. halabanensis M.Hughes sp. nov., B. karangputihensis Girm. sp. nov., B. kemumuensis M.Hughes sp. nov., B. korthalsiana Miq. ex M.Hughes sp. nov., B. kudoensis Girm. sp. nov., B. lilliputana M.Hughes sp. nov., B. olivacea Ardi sp. nov., B. raoensis M.Hughes sp. nov., B. simolapensis Ardi sp. nov.) and B. sect. Sphenanthera (B. pseudoscottii Girm. sp. nov.). Using the International Union for the Conservation of Nature criteria, 6 are considered to be Least Concern, 5 Vulnerable and 4 Data Deficient. A key to 58 of the 63 currently accepted Begonia species in Sumatra is provided.
The taxonomy of the deep-water homolid crabs Moloha grandperrini Guinot & Richer de Forges, 1995 and M. alisae Guinot & Richer de Forges, 1995 is re-examined, and the types redescribed and figured. Moloha alisae is reported from South Africa for the first time. A new species with an inflated carapace, M. tumida sp. nov., is also described from southern India and compared with its closest congeners.
Following ICZN (1999) Article 79 Chapter 17 (http://www.nhm.ac.uk/hosted-sites/iczn/code/), we, with the full support of the international community of rotifer researchers as expressed during subsequent international Rotifera symposia, developed a Candidate Part of the List of Available Names for species and genera of Rotifera from the start of zoological nomenclature to the year 2000.
Niphargus dancaui sp. nov., previously referred to as Niphargus cf. stygius, was sampled from various groundwater sites in and near the town of Mangalia (SE Romania) and described with Movile Cave (a sulfidic, chemoautotrophically based ecosystem) as type locality. A short comparison with Niphargus stygius specimens from Slovenia was made, together with a morphological analysis of interpopulational variability. Males of N. dancaui sp. nov. were relatively large (17 mm), with long antennae, pereiopods and uropod III. Females were slightly smaller, with shorter antennae, pereiopods and uropod III. Interpopulational variability was noticed in the chaetotaxy of the telson lobes and uropod III. N. dancaui sp. nov. is morphologically very close to N. lessiniensis and N. tridentinus, two species present in northern Italy, but distinct genetically from them based on 28S rRNA sequences. Instead, the closest relative of N. dancaui sp. nov. sequenced so far for this marker is N. montanarius, which inhabits a sulfidic cave system in central Italy. The work presented here contributes to our knowledge of groundwater crustacean biodiversity in general and of the systematics of the genus Niphargus in particular.
Ballomma, a new Afrotropical genus in the Cryptothelinae (Araneae, Zodariidae): eyes on the run
(2015)
Ballomma gen. nov. is described in the zodariid subfamily Cryptothelinae. It is characterized by the pairs of adjacent anterior median eyes and anterior lateral eyes and triangular palpal tarsus in the female, the concave tegulum with thin embolus in the male. Apart from the type species B. erasmus gen. et sp. nov. (♂♀), the genus contains B. haddadi gen. et sp. nov. (♂♀), B. neethlingi gen. et sp. nov. (♂♀), and B. legala gen. et sp. nov. (♀). A key to the species is provided. The restricted distribution of the genus is discussed.
The previously poorly known Southeast Asian spider genus Aetana Huber, 2005 is revised. Fifteen species are newly described, and the first SEM data and a first phylogenetic analysis of the genus are presented. Four species groups are well supported, one restricted to Borneo, two restricted to the Philippines, and one ranging from the Philippines to Fiji. The cladistic analysis and field observations suggest that the ancestor of Aetana built its web close to the ground, in confined spaces among and under rocks and logs. In at least two cases, evolutionary shifts of microhabitat resulted in species being adapted to life in higher forest strata, with correlated morphological and behavioral changes (lighter coloration; longer abdomen; additional sheet in web or more strongly domed web). The following species are newly described: A. abadae Huber, sp. nov., A. baganihan Huber, sp. nov., A. banahaw Huber, sp. nov., A. kiukoki Huber, sp. nov., A. libjo Huber, sp. nov., A. loboc Huber, sp. nov., A. lozadae Huber, sp. nov., A. manansalai Huber, sp. nov., A. ocampoi Huber, sp. nov., A. paragua Huber, sp. nov. and A. pasambai Huber, sp. nov. from the Philippines; A. gaya Huber, sp. nov., A. indah Huber, sp. nov., A. lambir Huber, sp. nov. and A. poring Huber, sp. nov. from northern Borneo. The female of A. kinabalu Huber, 2005 is newly described. A potential case of female genital dimorphism is documented in A. ocampoi Huber, sp. nov.
The study of subterranean Oniscidea in Portugal has been neglected for nearly 70 years, but recent investigations have revealed high diversity. All the terrestrial isopods known from caves of mainland Portugal, including data from the literature and new material, are listed, revealing new biodiversity patterns. Twenty-seven species, belonging to 15 genera and six families, are known, of which 16 species are considered to be exclusively from subterranean ecosystems, i.e., troglobionts. Trichoniscidae is the most diverse family. Seven species in the family Trichoniscidae and one species in the family Styloniscidae are described as new (all with Reboleira & Taiti as authors): Trichoniscoides bellesi sp. nov. from the Montejunto Massif; T. sicoensis sp. nov. from the Sicó Massif; Metatrichoniscoides salirensis sp. nov. from the typhonic valley of Caldas da Rainha; Troglonethes olissipoensis sp. nov. from the Lisbon Peninsula; T. arrabidaensis sp. nov. from the Arrábida Massif; Miktoniscus longispina sp. nov. from the Sicó Massif and Cesaredas Plateau; Moserius inexpectatus sp. nov. from the Estremenho Massif; and Cordioniscus lusitanicus sp. nov. from Alentejo and Algarve, the southernmost provinces of Portugal. The subgenus Trogleluma Vandel, 1946 (Armadillidiidae) is raised to genus level. In this geographic region terrestrial isopods are the richest group of cave-adapted animals.
The genus Savarna Huber, 2005 was previously one of the most poorly known Pholcinae genera. Less than 20 specimens (representing four nominal species) were available worldwide; nothing was known about ultrastructure, natural history, or relationships. We present the first SEM data, supporting the position of the genus in Pholcinae outside the Pholcus group of genera and weakly suggesting a closer relationship with the genera Khorata Huber, 2005, Spermophorides Wunderlich, 1992, and two undescribed species of unknown affinity from Borneo. We provide the first data about microhabitat, web structure, and reaction to disturbance. We clarify the type locality of Savarna tessellata (Simon, 1901) (“Jalor, Biserat”) and describe topotypical material. We describe the previously unknown male of Spermophora miser Bristowe, 1952 and transfer the species (that was previously considered incertae sedis) to Savarna as Savarna miser (Bristowe, 1952) comb. nov. Savarna baso (Roewer, 1963) is newly synonymized with S. miser. We describe the most northern species in the genus, Savarna kaeo sp. nov., and provide amendments to the descriptions of all previously described species.
A new monospecific genus, Pseudostegopterus gen. nov., endemic to the northwestern region of South Africa, is erected. The type species is described as Pseudospegopterus melonthinoides sp. nov. and is currently known only from male specimens. A provisional dichotomic key of the African Trichiina genera is also provided, in order to facilitate the identification of male specimens to the genus level.
Three new species of the order Monhysterida are described based on specimens obtained at depths of 8081 and 9177 m in the Kermadec Trench. Thelonema clarki sp. nov. is characterised by a large body size (3230–4461 μm), short cylindrical buccal cavity, gubernaculum without apophyses, and long conico-cylindrical tail. This is the first record of the genus since its original description over two decades ago from the Peru Basin. Metasphaerolaimus constrictus sp. nov. is characterised by a relatively long body (1232–1623 μm), slightly arcuate spicules without gubernaculum, and conico-cylindrical tail with inner cuticle conspicuously thickened immediately anterior to cylindrical portion. Monhystrella kermadecensis sp. nov. is characterised by a circle of papillose outer labial sensillae slightly anterior to the four short cephalic setae, gubernaculum with caudal apophyses, the presence of distinct cuticularised piece along anterior vaginal wall, and a relatively short conical (males) or conico-cylindrical tail (females) with conical, ventrally-curved spinneret. M. kermadecensis sp. nov. can be differentiated from all other species of the genus, and, indeed, the entire family, based on the variable position of the anterior gonad relative to the intestine. The new species is classified within the Monhysteridae, and not the closely-related Xyalidae, based on the small body size, a smooth cuticle, and the presence of six outer labial papillae and only one testis. Further work is required to clarify the placement of M. kermadecensis sp. nov. relative to other monhysterid genera. A tabular key to all ten valid Metasphaerolaimus species is presented.
Redescription of some species of Bryozoa described by J. Jullien and L. Calvet in the NE Atlantic
(2015)
Five species described by Jullien and/or Calvet from the NE Atlantic are redescribed and stabilized by typification: Hippothoa amoena, Schizoporella confusa, S. jullieni, S. ovum and Smittia guernei. Three new synonymies are established: Schizoporella jullieni with Hippothoa amoena, S. ovum with Escharina alderi, and Escharella pseudopunctata with Smittia guernei. A new trypostegid genus, Pulpeirina gen. nov., is erected for H. amoena. Three new combinations are introduced.
Metal ions as novel polarizing agents for dynamic nuclear polarization enhanced NMR spectroscopy
(2017)
High-spin complexes of Gd(III) and Mn(II) were introduced as polarizing agents (PAs) for solid-state dynamic nuclear polarization (DNP) in 2011. This dissertation was undertaken in 2013, with the intention of exploring these PAs further. Major goals of this work were to understand their DNP mechanism(s) and explore their application in biomolecular research. This cumulative thesis details the methods, advantages, and practical implications of using high-spin PAs for MAS DNP. Data from electron paramagnetic resonance (EPR) and NMR spectroscopy are discussed for a complete understanding of DNP mechanisms.
Out of the two main mechanisms − solid effect (SE) and cross effect (CE − active under experimental conditions of solid-state DNP, commonly used nitroxide PAs evoke CE owing to their broad EPR spectra. On the other hand, DNP mechanisms evoked by high-spin metal ions seem non-trivial due to additional features (originating from spin-orbit coupling or zero field splitting) in their EPR spectra. The features of the EPR signal generally influence the shape of enhancement profiles. Therefore, the metal ion with a simpler EPR signal i.e., Gd(III) , is chosen as the starting point for the investigation of DNP mechanisms. Varying concentrations (2, 10, 20 mM) of a water-soluble and stable complex Gd-DOTA was dissolved as the PA in a glycerol-water solution of 13C,15N - urea. Field profiles of DNP enhancement on each nuclear type (1H, 13C, and 15N) establishes SE as the active DNP mechanism at the smallest PA concentration (2 mM). This confirms the theoretical predictions that narrow line width of the Gd(III) EPR signal arising from the central transition (CT, ms = -1/2 +1/2) allows for resolved SE DNP. However, that is no longer the case at higher PA concentrations of 10 and 20 mM. At higher Gd(III) concentrations, the CE mechanism contributes significantly and varies with nuclear Larmor frequency (ωn) of the concerned nuclei. The enhancement maxima shifts towards the EPR resonance as the contribution from CE increases. This shift is evident in the field profiles of 15N and 13C, whereas that of 1H is least influenced. This observation can be explained by combining theoretical estimates with the experimental data; the CE is evoked by increased dipolar coupling (Dee) – a prerequisite for CE – between neighboring Gd(III) spins as the statistical inter-spin distance shortens at elevated concentrations. This finding is important because the knowledge of active DNP mechanisms is essential for accurate interpretation of results from DNP experiments.
From the experiments on Gd-DOTA it becomes clear that concentration, inter-spin distances, and hence induced Dee are intertwined. In order to explicitly address the influence of inter-spin distances on DNP mechanisms we started a collaboration with the group of Adelheid Godt (Bielefeld). In this collaborative project, bis-complexes of the type Gd(III)-spacer-Gd(III) with variable spacer lengths were investigated. These PAs provided an excellent model system where the influence of only inter-spin distances can be determined for a fixed Gd(III) concentration. A small PA concentration of 4 mM is used to ensure absence of significant inter-molecular dipolar interactions. A mono-Gd complex of similar geometry and chemistry is taken as a reference for SE DNP.
The mono-Gd complex yields enhancements arising from SE as expected from negligible inter-molecular Dee. The contribution of CE increases as the inter-spin distances between Gd(III) ions become shorter going from 3.4 nm 2.1 nm 1.4 nm 1.2 nm due to corresponding increase in Dee. The extent of CE on ωn follows the same trend as for Gd-DOTA. Highest CE contribution is observed on nuclei with the smallest ωn 15N because smaller ωn approaches the width of the EPR signal, this is an additional requirement for CE DNP.
The field position for maximum DNP enhancement corresponding to Gd-DOTA, is used for DNP experiments on Ubiquitin with an attached Gd-tag as PA. The success of DNP on this sample illustrates the possibility of site-directed DNP with metal ions tags as PAs. As a perspective Gd-tags can be used to examine change in conformation of a protein that would give higher enhancements due to CE if two Gd(III) labeled domains are closer in space. In a separate project, Mn(II) (s=5/2) bound to the divalent site of a hammerhead ribozyme was used as a PA which resulted in the first demonstration of intra-complex DNP using an intrinsically bound metal ion PA.
The collection of deep-sea pebble crabs (Leucosioidea) during the BIOPAPUA Expedition, comprising 8 species, including a species new to science, is significant because although the previously described species had not been recorded from the Bismarck and western Solomon Seas, they occurred in at least one nearby location (New Caledonia, Vanuatu, Solomon Is). Praebebalia fungifera sp. nov. is described and illustrated. It differs from its closest congener, P. septemspinosa Sakai, 1983, in bearing fungiform granules dorsally on carapace, shorter chelipeds, the relatively stout male first gonopod with a preapical row of setae and the beak-like tip, as compared to the rounded granules dorsally on the carapace, greatly elongate chelipeds and the slim, elongate, distally curved gonopod of P. septemspinosa, preapically set with very long setae and a hook-like tip.
Amage imajimai sp. nov., a new species of Ampharetidae (Annelida: Polychaeta) from Japanese waters
(2015)
A new polychaete species of the family Ampharetidae, Amage imajimai sp. nov., is described from deep waters of Sagami Bay, Japan. It is characterized by the possession of four pairs of branchiae, twelve thoracic uncinigers, eleven abdominal uncinigers, and the lack of thoracic notopodial cirri. The new species is named in honor of the renowned Japanese polychaetologist Minoru Imajima. An identification key for all Amage species from Japanese waters is provided.
Molecular phylogenetic analysis has demonstrated that the genus Gallinula is not monophyletic and comprises four major lineages. A review of the nomenclature of Gallinula shows that generic names are available for three lineages but that a fourth is as yet unnamed. A new monotypic genus, Paragallinula gen. nov., is described for Lesser Moorhen (Gallinula angulata Sundevall, 1850).
The new genus Palindroma gen. nov. is described in the Cryptothelinae, Zodariidae. Apart from the type species, P. morogorom gen. et sp. nov. (♂♀), the genus contains P. aleykyela gen. et sp. nov. (♂), P. avonova gen. et sp. nov. (♂♀), P. sinis gen. et sp. nov. (♂) and the somewhat aberrant species P. obmoimiombo gen. et sp. nov. (♂). The four typical representatives of the genus are characterized by the profile of the carapace with a slight dip, the absence of precoxal sclerites and the characters of the male palp with enlarged tibia, large subtegulum and tegular retrolateral knob. The genus occurs in miombo-woodland and coastal forest in East and Central Africa and this peculiar distribution is discussed. A key to the males of the Palindroma species is provided. Specimens of Palindroma have a particularly well-developed tibial process fitting in a shallow metatarsal pouch on all legs in both sexes. Although less conspicuous in some derived taxa, the feature appears to be present in all representatives of the Zodariidae, but not in possible sister-group taxa and is thus an autapomorphy of the family.
Two new junior synonyms, Pseudomesitius Duchaussoy, 1916 syn. nov. and Triglenus Marshall, 1905 syn. nov., for the genus Bradepyris Kieffer, 1905 are proposed and a new diagnosis for the genus is given. Two new species (based on males) from the Saharo-Arabian region are here described: Bradepyris jordanicus, sp. nov. and B. baleariensis, sp. nov. A brief revision, with a key to the males and females of all species of this genus, and the first male genitalia descriptions are also provided.
The genus Aquattuor Frederiksen, 2013 is revised. A. denticulatus Frederiksen, 2013 (type species) from the East Usambara Mts, Tanzania, is redescribed, and six new species are described: A. claudiahempae sp. nov. from Mt. Kilimanjaro, Tanzania, and five species from the Udzungwa Mts, Tanzania: A. longipala Enghoff sp. nov., A. major Enghoff sp. nov., A. stereosathe Enghoff sp. nov., A. submajor Enghoff sp. nov., and A. udzungwensis Enghoff sp. nov.
Twenty-three species of cheilostome bryozoans are described from the Malaysian islands of Penang and Langkawi based on a brief reconnaisance survey of shore localities. These are the first bryozoans to be formally described from either island and they demonstrate the potential for further research on these neglected suspension feeders. Of the 23 species recorded, 12 are anascans, half of which are malacostegines, and 11 are ascophorans. The new combinations Acanthodesia falsitenuis (Liu, 1992), A. perambulata (Louis & Menon, 2009) and A. irregulata (Liu, 1992) are introduced. Most of the species recorded are widespread in the Indo-Pacific, and some are apparently globally distributed in the tropics and subtropics, including the invasive fouling species Bugula neritina, Hippoporina indica and Schizoporella japonica, as well as the coral reef associates Cranosina coronata and Hippopodina feegeensis. Plastic debris and glass bottles were encrusted by Jellyella eburnea, a coloniser of floating biological and man-made objects that is becoming widespread in the tropics and subtropics of the world’s oceans.
Three new species of Eburiini are described: Beraba hovorei sp. nov. from Ecuador, Eburella migueli sp. nov from Colombia and Susuacanga marcelae sp. nov. from Mexico. A new combination, Quiacaua vespertina (Monné & Martins, 1973) comb. nov., and the transfer of Eburia (Eburia) stroheckeri Knull, 1949 to Eburia (Eleutho) Thomson, 1864 are proposed. A key to species of Beraba Martins, 1997, Eburella Monné & Martins, 1973 and Quiacaua Martins, 1997 is provided. Moreover, the geographical distribution for 15 species of Eburiini is expanded. A lectotype and a paralectotype for Volxemia dianella Lameere, 1884 are designated.
Four new species of the genus Caccothryptus (Coleoptera: Limnichidae) are described: C. taiwanus from Taiwan; C. orion from Okinawa; C. tibetanus and C. chayuensis from Tibet. All the species belong to the testudo species group (sensu Hernando & Ribera 2014). Additional specimen data and an updated species list are also given, and C. testudo Champion, 1923 is newly recorded from Thailand.
Chiraziulus is a highly disjunct, hitherto monotypic genus of cambalid millipedes, geographically isolated in Iran by more than 7000 km from its presumed closest relatives in East Asia and North America. Recent fieldwork in caves of Iran has provided several specimens of this genus, allowing the description of Chiraziulus troglopersicus sp. nov. The intraspecific variability of the type species, C. kaiseri Mauriès, 1983, is illustrated with scanning electron micrographs. Chiraziulus is characterized by exceedingly long microtrichose gonopod flagella which from their insertion points on the posterior face of the anterior gonopod coxites first point distad instead of basad or basad-posteriad as in most other flagelliferous Cambalidea (and Julida), then traverse a groove on the mesal surface of the anterior gonopod coxites, making a full (360°) loop. The same feature is also illustrated for the first time in the genus Cambala. The patterns and prevalence of the infection with a species of ectoparasitic fungus of the genus Rickia (order Laboulbeniales) in the type material of C. kaiseri is described. An updated review of the cave-adapted fauna of Iran is given.
Keys and diagnoses of North European aphids (Hemiptera, Aphidoidea) associated with mosses, horsetails and ferns are given, based on fresh and freeze-dried material. Numerous externally visible and thus informative characters, that are absent in cleared, slide-mounted specimens, such as body shape colours, wax coating and pattern etc., are utilized. Most of the species are illustrated by photographs of live specimens and drawings. Root-feeding species living in the moss layer or otherwise often present in moss samples are also included, even if their hosts were spermatophytes. The combination of colour images and diagnoses, utilizing easily observed characters, allows the identification of a large number of species already in the field, and many more at home with the aid of a stereo microscope. Host plant relationships and association with ants are summarised, including new records. Brief accounts on aphid life cycles, freeze-drying preparation techniques, etc. are also given to support the use of the keys.
A new sepioline species, Sepiola boletzkyi sp. nov. (Cephalopoda: Sepiolidae), is described based on two specimens from the Aegean Sea (eastern Mediterranean). The type specimens are lodged in the Ege University Faculty of Fisheries Museum of Izmir (Turkey). The new species belongs to the Sepiola atlantica group sensu Naef, hence it is compared with the species in this group, namely Sepiola affinis, Sepiola atlantica, Sepiola bursadhaesa, Sepiola intermedia, Sepiola robusta, Sepiola rondeletii, Sepiola steenstrupiana and Sepiola tridens. The male of S. boletzkyi sp. nov. differs from all the others in having the combination of homomorphous ventral arm tips, eight enlarged suckers, subdivided into two groups, in the dorsal row of the distal part of the hectocotylus and a dorsal lobe complementing the copulatory apparatus. In females of S. boletzkyi sp. nov. the bursa copulatrix is large and, unlike all other species in the genus, has a large fungiform process towards the mantle wall. The discovery of S. boletzkyi sp. nov. increases to 12 the number of NE Atlantic- Mediterranean species of Sepiola.
Two new species of Leptanilloides are described: L. copalinga Delsinne & Donoso sp. nov. and L. prometea Delsinne & Donoso sp. nov., based on workers collected in the leaf litter and soil of the Andes of southern Ecuador. Both species belong to the L. biconstricta species-group (formally diagnosed here). The metatibial gland, considered a synapomorphy for Dorylinae, is observed in L. prometea sp. nov. but seems absent in L. copalinga sp. nov. We provide a COI DNA barcode for both species and a revised key for the worker caste of all known species in the genus. We also describe a single male identified as a potential new Leptanilloides species on the basis of morphology. Furthermore, its mitochondrial COI gene sequence does not match any previously barcoded species. However, we refrain from giving it a specific name because of our lack of knowledge about the worker caste. So far, half of the 14 Leptanilloides species have been discovered above 1500 m in the mountain forests or páramos of the Ecuadorian Andes, confirming, if needed, the biological significance of these threatened habitats.
Sharon gen. nov. is here described to include Asaphes? amoenus Philippi, 1861 comb. nov. from Chile. A redescription of the species is based on the female holotype and material from different geographic locations. Candèze (1891) placed Asaphes amoenus and Parasaphes elegans in the suprageneric group Asaphites. We discuss differences between Sharon gen. nov. and Hemicrepidius Germar, 1839, where Asaphes amoenus was later placed by Blackwelder (1944). Based on morphological characters, Sharon gen. nov. appears to be related to Parasaphes Candèze, 1881, Wynarka Calder, 1986, and Tasmanelater Calder, 1996, all from Australia, suggesting Gondwanan relationships.
Im Kindes- und Jugendalter gehoert das Rhabdomyosarkom zu den haeufigsten Weichteilsarkomen. Bisher belaeuft sich das Therapieverfahren auf chirurgische Entfernung, gefolgt von Chemotherapie, bzw. bei nicht-operablen Faellen auf Radiotherapie und Chemotherapie, jedoch haben sich die Ueberlebenschancen fuer Patienten mit einer Erkrankung in metastasiertem oder rezidiviertem Stadium trotz intensiver Forschung ueber mehrere Jahrzehnte hinweg kaum gebessert und bleiben bei unter 30%. Neue therapeutische Strategien versuchen das Immunsystem des Patienten zu modulieren und dieses gezielter oder aggressiver gegen Tumorzellen zu machen. Nebst direkter Injektion von Zytokinen oder Antikoerpern bietet die adoptive Immunzelltherapie einen vielversprechenden Ansatz. In der vorliegenden Arbeit lag der Fokus auf Natuerlichen Killer- (NK) Zellen, da diese ein hohes zytotoxisches Potential gegenueber Tumorzellen aufweisen. Eine der groessten Herausforderungen der NK-Zellforschung ist die Breitstellung ausreichender Mengen an NK-Zellen mit optimaler antitumoraler Funktion fuer den klinischen Einsatz. Viele aktuell erprobte NK-Zellexpansionsstrategien basieren auf der Verwendung von Hilfs- oder Feeder-Zellen (Versorgerzellen), die jedoch vor der Applikation in Patienten aus dem finalen Produkt entfernt werden muessen. In der vorliegenden Arbeit sollten Feeder-zellfreie NK-Zellexpansionsprotokolle unter Verwendung von Gammakettenzytokinen getestet werden.
Interleukin (IL-) 15 erwies sich dabei vor allem fuer die Vermehrung der NK-Zellen als besonders foerderlich. Im Vergleich dazu fielen die Expansionsraten mit IL-2 oder IL-21 geringer aus. Interessanterweise wurde der expansionsfoerdernde Effekt von IL-15 durch dauerhafte Anwesenheit von IL-21 im Kulturmedium gehemmt. Ein kurzer, dreitaegiger IL-21-Boost am Ende der Expansionsphase wirkte sich wiederum positiv auf die NK-Zellexpansionsraten aus. Zudem zeigte sich durch IL-21 ein vermehrtes Auftreten von NK-Zellen des reiferen CD16posCD56dim Phaenotyps, der die zytotoxische Funktion vermittelt. Bei Degranulationsuntersuchungen wurden eine IL-21-induzierte Exozytoseaktivitaet und die vermehrte Ausschuettung von Perforin und Granzym B, welche Apoptose in den Zielzellen ausloesen, beobachtet. Vor allem der dreitaegige Boost mit IL-21 bewirkte eine gesteigerte Zytotoxizitaet gegenueber Tumorzellen, insbesondere gegenueber Rhabdomyosarkomzellen.
Auf dieser Grundlage bot es sich an fuer die NK-Zellexpansion ein Zwei-Phasen-Protokoll anzuwenden, bestehend aus einer initialen Proliferationsphase mit IL-15 und einem anschliessendem IL-21-Boost, durch den die antitumorale Funktionalitaet der NK-Zellen gesteigert wurde. Dieses IL-15+21boost-Protokoll wurde mit anderen Kombinationen aus den Gammakettenzytokinen IL-2, IL-15 und IL-21 verglichen und stellte sich hinsichtlich der NK-Zellexpansionsraten, der Degranulationskapazitaet und der damit verbundenen Zytotoxizitaet als den anderen Protokollen ueberlegen heraus.
Zytokinexpandierte NK-Zellen zeigten eine hoehere Rezeptorexpression an ihren Oberflaechen als unstimulierte Zellen. Die Expansion mit dem IL-15+21boost-Protokoll bewirkte die hoechste Dichte des Todesrezeptors TRAIL, jedoch auch der inhibitorischen KIR2D-Rezeptorfamilie. Fuer andere Oberflaechenmarker ergab sich jeweils eine mittlere Expressionsdichte verglichen mit dem IL-15- bzw. dem IL-15+21-Expansionsprotokoll. Die Sekretion von proinflammatorischen Zytokinen wie Interferon-gamma (IFN-g) und Tumor-Nekrose-Faktor-alpha (TNF-a) wurde zudem verstaerkt durch IL-21 angeregt, aber ebenso die Sekretion des immunsupprimierenden IL-10.
Weiter wurden die zytoinexpandierten NK-Zellen zur UEberpruefung ihrer in vivo Funktionalitaet anhand eines praeklinischen Xenograftmodells unter Verwendung von NOD SCID IL-2-Rgamma-/- (NSG) Maeusen und der Technologie der in-vivo-Biolumineszenzbildgebung getestet. Dabei konnte beobachtet werden, dass die NK-Zellen das Wachstum luciferaseexprimierender humaner Rhabdomyosarkome verlangsamten. Die Wirksamkeit der IL-15+21boost-expandierten NK-Zellen zeigte sich vor allem in einem kombinierten Ansatz, bei dem die Tumore zunaechst mit ionisierender Strahlung behandelt wurden und residuale Rhabdomyosarkomzellen anschliessend durch den adoptiven Transfer von humanen NK-Zellen in ihrem Wachstum gehemmt waren, solange die NK-Zelltherapie andauerte. Somit stellte sich die Kombination aus Bestrahlung und NK-Zelltransfer als wirksamer im Einsatz gegen Rhabdomyosarkome heraus als die alleinige Behandlung der Tumore durch Radiotherapie.
Zusammengefasst konnte in dieser Arbeit ein NK-Zellexpansionsprotokoll entwickelt werden, dass durch den ausschliesslichen Einsatz von Gammakettenzytokinen zu einem funktionalen NK-Zellprodukt fuehrte, welches auch in vivo lytische Aktivitaet gegenueber Rhabdomyosarkomzellen aufwies.
The Earwig Collection (Dermaptera) of the Manchester Museum, UK, with a complete type catalogue
(2015)
This paper presents a description of the worldwide Dermaptera collection of the Manchester Museum, UK. In total, the collection contains over 16,700 specimens and represents 835 species and subspecies (approximately 44% of the Dermaptera world fauna). The composition of the collection is described and a brief account is given of its history and those instrumental in its development, notably W.D. Hincks (1906–1961) and A. Brindle (1915–2001). Correspondence held at the museum relating to their work on Dermaptera is listed and examples relating to Labidura herculeana (Fabricius, 1798) and some of the parasitic earwigs in the collection are explored. Finally, a complete type catalogue of the Manchester Museum’s Dermaptera is presented; it is arranged alphabetically by species name as originally described, with photographs of all holotypes and their corresponding data labels. The collection contains 40 holotypes and 694 secondary types (allotypes, syntypes or paratypes), representing 283 species and subspecies, an estimated 15% of the Dermaptera world fauna.
Actaea grimaldii, a new species of reef crab from Papua New Guinea (Crustacea, Brachyura, Xanthidae)
(2015)
A new species of xanthid crab, Actaea grimaldii, is described from the coral reefs of Papua New Guinea. This species has a distinctive red and white coloration and is closest to Actaea spinosissima Borradaile, 1902, from the Indian Ocean. However, the new species can be distinguished by the arrangement of spines on the carapace, chelipeds and ambulatory legs, and the structure of the male gonopods. Actaea grimaldii sp. nov. has also been confused with A. polyacantha (Heller, 1861), but differs markedly in the carapace armature.
A new genus, Campodesmoides gen. nov., is described to only encompass C. corniger sp. nov., from Cameroon. This genus and species is distinguished from the few known species of the small western African family Campodesmidae, all currently in Campodesmus, by the much longer antennae and legs, the normal pore formula with ozopores borne on porosteles, and the suberect and distally twisted gonopod, coupled with peculiar horns on a few anterior postcollum segments. A new Campodesmus is also described, C. alobatus sp. nov., from Ivory Coast, which differs from congeners primarily in the lack of a dorsal/lateral lobe on the otherwise usual and strongly subcircular gonopod telopodite, albeit the latter is not directed mesad, but held subparallel to the main body axis.
A new species of Rhaphiostylis, R. minima sp. nov. from Liberia and Ivory Coast, is described and illustrated here. It is characterised by its comparatively small size, an ovate to lanceolate leaf blade with long drip tip and a partly glabrous ovary that is in shape in between those of R. elegans Engl. and R. preussii Engl. Rhaphiostylis elegans is lectotypified and illustrated here.
Three species of the genus Pseudocandona Kaufmann, 1900 and one of the genus Undulacandona Smith, 2011, collected from freshwater habitats in Japan, are described. The Pseudocandona species, Pseudocandona becca sp. nov., Pseudocandona atmeta sp. nov. and Pseudocandona falcula sp. nov., all belong to the rostrata-group. Previous reports of Pseudocandona rostrata (Brady & Norman, 1889) and Pseudocandona sarsi (Hartwig, 1899) from Japan are reassessed and are subsequently synonymized with Pseudocandona tenuirostris Hiruta & Mawatari, 2013 and Pseudocandona falcula sp. nov. respectively. Undulacandona colymba sp. nov. is only the second to be described in this genus. Like the type species of the genus, it is a stygobiont, collected from groundwater in Shiga Prefecture. Additional records of Candona candida (O.F. Müller, 1776), are presented herein; so far, Japanese records of this species are restricted to the eastern part of Hokkaido.
