Warum in der Politik so viel von »Architektur« gesprochen wird und warum Architektur an sich nicht demokratisch sein kann, darüber hat sich der Architekturhistoriker Carsten Ruhl Gedanken gemacht
Globalisierung, Migration, neue Geschlechterverhältnisse, Bildungsexpansion: Dies alles verändert unsere sozialen Strukturen. Wie wirkt sich dieser Wandel auf Gesellschaft und Individuum aus? Diesen Fragen geht die DFG-Forschungsgruppe RISS (»Reconfiguration and Internalization of Social Structure«) nach.
Wie funktioniert die Verneinung in der Sprache? Und wie hängen die sprachlichen Strukturen hierfür mit der Wahrnehmung im Gehirn zusammen? Solchen Fragen widmet sich der neue Sonderforschungsbereich 1629 »Negation: Ein sprachliches und außersprachliches Phänomen« (NegLaB) an der Goethe-Universität. Bereits in die dritte Förderphase geht ein SFB aus der Biochemie, der sich mit der selektiven Autophagie befasst, einem natürlichen Vorgang, mit dem Zellen fehlerhafte oder überflüssige Bestandteile gezielt entsorgen können.
The Åland Islands archipelago enjoys a special international status sui generis, which essentially encompasses demilitarisation, neutralisation, and autonomy. This status is guaranteed under international law by the agreements of 1921, 1940, and 1947, which are still in force. Furthermore, there are convincing reasons to assume that the Åland Islands regime has grown into European customary law. By virtue of her international (treaty) obligations, Finland cannot unilaterally change this status under the present conditions, irrespective of domestic (constitutional) decisions. While integration into NATO’s collective defence system and the EU’s Common Security and Defence Policy structures is compatible with the special status of the Åland Islands, care must be taken by Finland and her partners to ensure that the obligations arising from these developments are fulfilled in accordance with the demilitarised and neutralised status of the archipelago. This includes that the use by Finnish troops for preventive defence, beyond the exceptions laid down in the 1921 Åland Agreement, is only permitted in the case (of threat) of an immediate and clearly identifiable attack.
The autonomous character of the Åland Islands was established under a League of Nations dispute settlement and implemented, inter alia, in Finnish legislation. Its essence even grew into customary law. The arrangements of 1921, however, do not constitute a bilateral treaty between Finland and Sweden. The UN assumes that the international mechanism to protect Åland’s autonomy did not become obsolete with the demise of the League of Nations, but was only “suspended until such time as an express decision has been taken by the United Nations to put it back into force”. A corresponding proposal could be submitted, in any case, both by Finland and/or Sweden or possibly even by any other UN member state, for discussion in the Sixth Committee. However, the final decision to re-activate this special mechanism would have to be adopted by the UN General Assembly.
EU Law applies to the Åland Islands in principle; however, Finland’s Accession Treaty to the EU to which Protocol No. 2 on the Åland Islands was annexed, established a number of specific rules which are still in force today. This, most notably, results in the limited application of value added tax and excise duties in the Åland Islands. Therefore, the rules on customs procedures apply with respect to the movement of goods to and from the Åland Islands. In addition, other provisions of Union law, in particular those relating to fundamental freedoms and European state aid law, may be relevant in view of the special fiscal status of the Åland Islands. However, assessing individual cases would require further information and in-depth studies. Irrespective of the requirements set out in the said Protocol, the EU is obliged to respect the national identity of Member States pursuant to Article 4 para. 2 TEU; this obligation includes respect for the special status of the Åland Islands under both international and Finnish constitutional law.
Previous phylogenetic analyses of the grass-specialist leafhopper tribe Chiasmini have resolved relationships among genera but have included few representatives of individual genera. Here the phylogeny of 20 Chinese species belonging to 8 chiasmine genera was investigated by combining DNA sequence data from two mitochondrial genes (COI, 16S) and two nuclear genes (H3, 28S). In both maximum likelihood (ML) and Bayesian inference (BI) analyses, relationships among genera were largely consistent with prior analyses, with most members of the tribe placed into two sister clades: (Exitianus + Nephotettix) and the remaining five sampled genera. To examine morphology-based species definitions in the taxonomically difficult genus Exitianus Ball, 1929, one mitochondrial gene (COI) and one nuclear gene (ITS2) were used to infer the phylogenetic relationships and status of two common and widespread species and compare the performance of different molecular species-delimitation methods. These analyses divide the included populations into two well-supported clades corresponding to current morphological species concepts but some inconsistencies occurred under the jMOTU, ABGD and bPTP methods depending on the which gene and analytical parameter values were selected. Considering the variable results yielded by methods employing single loci, the BPP method, which combines data from multiple loci, may be more reliable in Exitianus.
The Cladonematidae are a family of hydrozoans with a worldwide distribution and morphological adaptations for a benthic mode of life. Species of this family are characterized by high morphological variability, which has caused many taxonomical debates, mainly for the species of the genera Eleutheria Quatrefages, 1842 and Staurocladia Hartlaub, 1917. Herein, we describe Staurocladia dzilamensis sp. nov., a new species of crawling hydromedusa from the southern Gulf of Mexico. This finding also constitutes the first record of the genus Staurocladia for the Gulf of Mexico. The presence of additional nematocyst clusters, supplementing the apical one on the upper branch of the tentacles, places it within Staurocladia. The presence of exumbrellar buds, a conspicuous marginal ring of nematocysts, 6–11 bifid tentacles with lower branches longer than their upper counterpart, the cnidome with stenoteles of two size classes, and two nematocyst clusters on the upper branch supplementing the apical one, opposite placed alternately on its aboral and oral sides permits to differentiate S. dzilamensis from its congeners. A taxonomic key for the species of Staurocladia is provided.
Eine finalisierte Fassung des Beitrags wird 2024 in einem von Burchard/Schmitt-Leonardy/Singelnstein/Zabel herausgegebenen Sammelband („Alternativen zum Strafrecht“) erscheinen.
Im Zentrum des Beitrags steht jedoch nicht der Versuch, positiv Alternativen zum oder im Strafrecht zu formulieren. Vielmehr ist der Begriff der Alternativlosigkeit erkenntnisleitend, konkret die Identifizierung gesellschaftlich-politischer Wirkmächte und innerstrafrechtlicher Deutungsmuster, die eine (auch) strafrechtliche Bewältigung der durch den menschengemachten Klimawandel aufgeworfenen Konflikte alternativlos erscheinen lassen können.
Dazu wird die jüngst aufgekommene Debatte um ein Klimaschutzstrafrecht aus einer zukunftssoziologischen und strafrechtswissenschaftlichen Perspektive analysiert. Im Zentrum des Beitrags steht die These, dass sich gerade die Verbindung von katastrophischen Zukunftsvorstellungen – hier erschlossen über den zukunftssoziologischen Schlüsselbegriff der Imagination und deskriptiv-analytisch als „Klimakatastrophismus“ bezeichnet – und Exzeptionalisierungen des Strafrechts als Treiber in die imaginative Sackgasse der Alternativlosigkeit erweist.
Die verdichtete Imagination, das die Zukunfts eine Katastrophe sei („Klimakatastrophismus“), befördert als ein an Boden gewinnendes kollektives Deutungsmuster eine intensivierte Sozialkontrolle und Punitivität.
Der kriminalpolitisch expansive Kurs einer mit radikalisierten Selbsterhaltungsfragen konfrontierten Gesellschaft scheint in gesellschaftlich wie dogmatisch tief verankerten Exzeptionalisierungen des Strafrechts – wie der Zuschreibung, (nur) strafwürdige Sozialschädlichkeit adressieren zu dürfen, dies aufgrund einer regulativen und expressiven Ausnahmestellung aber auch in besonderer Weise zu können (oder zu müssen) – durchaus Widerhall zu finden. Dadurch entsteht ein strafrechtsexpansives (weil rechtfertigendes) Momentum, das der ohnehin in der Herausbildung begriffenen Legalisierung eines Klimaschutzstrafrechts Vorschub leistet.
Es entspricht den vornehmen Aufgaben der Strafrechtswissenschaft, diesen Entwicklungen prospektiv vorauszugreifen, sie aufzuklären und kritisch zu wenden – gerade im Hinblick auf die Gegenläufigkeit und Brüchigkeit gesellschaftlicher Entwicklungen oder die Kontingenz eines als politisch gelesenen Strafrechts. Eine kritische Strafrechtswissenschaft darf sich dabei nicht allein, allemal nicht unreflektiert auf tradierte Formen der Strafrechtsbegrenzung zurückziehen.
Die Verfassungsgeschichte der Bundesrepublik Deutschland beginnt in Frankfurt: Am 1. Juli vor 75 Jahren haben die Militärgouverneure der drei Westmächte im Eisenhower-Saal des I.G. Farben-Haus (heute Campus Westend) drei Urkunden übergeben. Diese »Frankfurter Dokumente« enthielten den Auftrag, eine Verfassung für das künftige Deutschland zu erarbeiten.
Um schnelleres Handeln in Sachen Klimaschutz zu erzwingen, kleben sich Aktivisten der »Letzten Generation« auf der Straße fest, werfen Suppe auf Kunstwerke und versuchen, ihre Ziele durch einen Hungerstreik zu erzwingen. Wie weit darf »ziviler Ungehorsam« gehen, ohne die Rechtsordnung zu gefährden? Darüber sprach Dirk Frank mit Samira Akbarian und Uwe Volkmann, die beide zum
Öffentlichen Recht forschen.
Although initially described as a subgenus of Copris Geoffroy, 1762, Homocopris had long been treated as a junior synonym of Dichotomius Hope, 1838 (Martínez 1951) until it was reclassified as a distinct genus (Vaz-de-Mello et al. 2010). Herein, we revisit the taxonomy of Homocopris. In doing so: we describe two new species previously considered to represent the Brazilian population of Homocopris torulosus (Eschscholtz, 1822); revalidate Pinotus punctatissimus from synonymy under Homocopris torulosus and place it in Homocopris as had previously been done only informally (González et al. 2015; Rebolledo et al. 2017); recognize two new synonymies; and describe a new genus, Andinocopris gen. nov., which includes two former members of Homocopris. Presently, Homocopris includes four species: H. torulosus, H. punctatissimus (Curtis, 1845) comb. nov., H. grossiorum sp. nov. and H. williami sp. nov. Andinocopris includes A. achamas (Harold, 1867) gen. et comb. nov. and A. buckleyi (Waterhouse, 1891) gen. et comb. nov. Pinotus simulator Luederwaldt, 1936 is here considered a new junior synonym of Andinocopris buckleyi. An identification key to members of both genera is provided as well as images of diagnostic characters for all species. Finally, we discuss the placement of Andinocopris and Homocopris within Scarabaeinae and propose a new tribe, Homocoprini tribe nov., to include both genera.
The genus Neocranaus Roewer, 1913 is revisited, its composition is expanded from two to five species and a new generic diagnosis is presented. Neocranaus albiconspersus Roewer, 1913, type species of the genus, is redescribed. The genus Tolimaius Roewer, 1915 syn. nov. is considered as a junior subjective synonym of Neocranaus, its sole member being transferred to Neocranaus – N. pectinitibialis (Roewer, 1915) comb. nov. – and redescribed here. The new combination Neocranaus laevifrons (Roewer, 1917) comb. nov. is proposed for Holocranaus laevifrons Roewer, 1917. The new species Neocranaus gladius Villarreal & Kury sp. nov. is described, from P.N.N. Yariguíes, Santander Department, Colombia. For the first time, the genital structure of this genus is illustrated. A key to the identification of the males of Neocranaus and some considerations about the reproductive biology of N. albiconspersus and N. pectinitibialis are presented.
Empty shells (thanatocoenoses) have been reviewed of species in the genus Granulina (Gastropoda: Granulinidae) from the lower shelf and upper bathyal zones off Mauritania and Western Sahara. We encountered nine species of which four were already known from off Mauritania. Four new species are proposed herein: Granulina reginae sp. nov., G. ronaldi sp. nov., G. sandrae sp. nov. and G. sigridae sp. nov. These four sympatric new species lack labial denticles and they probably form a phyletic clade with a common ancestor. Most hitherto known species in Granulina from the NE Atlantic Ocean and the Mediterranean possess labial denticles. One additional new species with denticles was left in open nomenclature because the material available was considered inadequate. Species in Granulina from Mauritania and Western Sahara have not been found off NW Morocco or the Canary Islands, and the species known from NW Morocco and the Canary Islands have not been found off Mauritania and Western Sahara. The southern extents of the distributions of the Mauritanian species are currently uncertain as additional sampling would be required off Senegal or further South. A key to Mauritanian species in Granulina is given.
A comprehensive review of the enigmatic genus Masona van Achterberg is provided. Two new species are described from the USA: Masona neon Dal Pos & Martens sp. nov. from Puerto Rico, and Masona wow Dal Pos & Martens sp. nov. from California. A key to the world species of Masona is presented, together with a discussion of the morphology of the genus and an annotated catalogue of the species. [Masona] timpaynei Quicke, 2019, is excluded from Braconidae and placed as incertae sedis in the Ichneumonidae, subfamily Neorhacodinae.
The vetigastropod material collected on Walters Shoal during Cruise MD208 of the Tropical Deep-Sea Benthos programme is documented. In total, 50 species were obtained, 30 of which are new and apparently endemic to the seamount. Of the other 20 species, eight are regionally endemic to the south-western Indian Ocean, 11 are more widely distributed in the Indo-West Pacific and one is possibly of deep-water Atlantic origin. The primary affinities of the fauna are with warm temperate South Africa and the tropical western Indian Ocean, but one species is potentially a seamount endemic of southern affinity. A new pseudococculinid genus living on decomposing bird feathers is described, a biogenic substrate association previously unknown in the Mollusca. The following new genera are described: Imbricoscelis gen. nov. and Pterodacna gen. nov. The following new species are described: Akritogyra crenulata sp. nov., Bathymophila williamsae sp. nov., Benthobrookula araneum sp. nov., Be. galeneae sp. nov., Be. laticostata sp. nov., Be. scalaroides sp. nov., Be. semisculpta sp. nov., Bruceina areneformis sp. nov., Calliostoma pantopunctatum sp. nov., Cantrainea herosae sp. nov., Carinastele achrosta sp. nov., Cornisepta marshalli sp. nov., Emarginula lentiginosa sp. nov., E. nodulicostata sp. nov., E. retrogyra sp. nov., E. salebrosa sp. nov., Fluxinella dufresneae sp. nov., Gibbula roseosticta sp. nov., Hadroconus scobina sp. nov., Kaiparathina monticola sp. nov., Lissotesta wareni sp. nov., Microcollonia miniata sp. nov., Mikro crassus sp. nov., Parviturbo cicatricosus sp. nov., Phragmomphalina candida sp. nov., Pterodacna boucheti gen. et sp. nov., Solariella asaphea sp. nov., Spinicalliotropis lepidota sp. nov., Stomatella multilirata sp. nov. and Trenchia mcleani sp. nov. The following new combinations are proposed: Brookula coronis Barnard, 1963 is transferred to Imbricoscelis gen. nov., Cantharidus nolfi Poppe, Tagaro & H. Dekker, 2006 is transferred to Kaiparathina Laws, 1941 and Solariella incisura Melvill, 1909 is transferred to Phragmomphalina Herbert & Williams, 2020. The following new synonyms are proposed: Carinastele wareni Vilvens, 2014 is a synonym of Bruceina cognata (Marshall, 1988); Fluxinella stellaris Bozzetti, 2008 is a synonym of Agagus stellamaris Herbert, 1991.
Twenty-one species of the genus Lecithocera Herrich-Schäffer, 1853 from China are described as new: L. angustifolia sp. nov., L. asticta sp. nov., L. balteiformis sp. nov., L. bicornuta sp. nov., L. bigeminata sp. nov., L. duplicispinea sp. nov., L. flavalba sp. nov., L. flavistriata sp. nov., L. furvibasis sp. nov., L. laticuculla sp. nov., L. ligulacea sp. nov., L. margirecta sp. nov., L. medogensis sp. nov., L. nullisigna sp. nov., L. parviflava sp. nov., L. parvispinea sp. nov., L. serratiloba sp. nov., L. sichuanensis sp. nov., L. tenuextrema sp. nov., L. tumicuculla sp. nov. and L. yunnanensis sp. nov.

The females of four species are described for the first time: L. alpina, L. haviensis, L. neosticta and L. orbiculata. Six new combinations are proposed: Lecithocera platomona (Wu, 1997) comb. nov. and L. stimulata (Wu, 1994) comb. nov. transferred from the genus Quassitagma; L. frisilina (Gozmány, 1978) comb. nov. transferred from the genus Recontracta; L. baliocata (Wu, 1994) comb. nov., L. sarmenta (Wu, 1994) comb. nov. and L. stictata (Wu, 1994) comb. nov. transferred from the genus Galoxestis. Images of adults and genitalia for all treated species are given, along with a checklist of all Chinese species of Lecithocera.
Sipuncula are marine unsegmented worms that can be found in benthic habitats, from shallow to deep-sea waters. In Mexico these worms have been scarcely studied. Among nine studies in the entire Mexican Pacific coasts, seven are from the central and northwestern Mexican Pacific. For over 80 years, only 24 species have been recorded. To improve the knowledge of the sipunculans from the central and northwestern Mexican Pacific, 501 specimens from three scientific collections of Mexico were revised. The specimens were collected by diverse methods from intertidal, subtidal, and bathyal depths (~1000 m), from 27 locations along the central and northwestern Mexican Pacific. Sixteen taxa belonging to nine genera and five families were identified. One species is recorded for the first time in the Mexican Pacific and five new species are described, one from intertidal and shallow subtidal depths: Phascolosoma (Phascolosoma) azteca sp. nov.; two from subtidal depths: Phascolion (Lesenka) salgadoi sp. nov. and Sipunculus (Sipunculus) bastidai sp. nov.; and two from bathyal depths: Apionsoma (Apionsoma) silviae sp. nov. and Apionsoma (Edmondsius) hendrickxi sp. nov.

Dorylaimellus attenuatus sp. nov. has a 0.73–0.84 mm long body; lip region rounded, offset; odontostyle attenuated with indistinct lumen, odontophore 9–10 µm long; expanded part of pharynx 39–48% of neck length; female genital system amphidelphic and tail long filiform. Dorylaimellus cylindricaudatus sp. nov. has a 1.0–1.15 mm long body; lip region rounded, offset; odontostyle 4 µm long, odontophore 11–12 µm long; expanded part of pharynx 47–56% of neck length; female genital system amphidelphic, and tail elongate-cylindrical with rounded terminus. Dorylaimellus karnatakensis sp. nov. has a 1.2–1.3 mm long body; lip region rounded, offset; odontostyle 5 µm long, odontophore 12–13 µm long; expanded part of pharynx 45–53% of neck length; female genital system amphidelphic; spicules 22 µm long, ventromedian supplements four, and tail elongate-conoid dorsally convex. Dorylaimellus kasplateauensis sp. nov. has a 0.68–0.83 mm long body, lip region with a weak perioral disc; odontostyle 6–7 µm long, odontophore 11–14 µm long; expanded part of pharynx 38–43% of neck length; female genital system amphidelphic, and tail elongate arcuate conoid. Dorylaimellus tropicus sp. nov. has a 0.6–0.7 mm long body; lip region rounded, offset; odontostyle 4–5 µm long, odontophore 8–10 µm long; hemizonid present; expanded part of pharynx 43–52% of neck length; female genital system amphidelphic and tail elongate-filiform, sudden tapering, ending with rounded tip. Dorylaimellus andrassyi, D. discocephalus, D. belondirelloides, D. chakpilus are redescribed based on the specimens collected from several localities of the Western Ghats.
Sarinda sombraluminosa Hagopián, Laborda & Simó sp. nov. and Sarinda contraluz Hagopián & Bustamante sp. nov. are described from Uruguay based on males and females. New records of Parafluda banksi Chickering, 1946 and Sarinda marcosi Piza, 1937 for the country are provided. Illustrations and electron micrographs of sexual characters, photographs of alive specimens, natural history data and a distribution map of species of Sarandini from Uruguay are provided.
Oceanic islands harbor a unique and distinct fauna and flora, usually isolated by distance and the deep sea, making them fascinating environments to study. Despite their importance, taxonomic accounts from Brazilian oceanic islands have only recently begun to focus on important groups such as the Syllidae family. In this article, we present detailed descriptions and illustrations of two new species, Brevicirrosyllis paulolanai sp. nov. from Trindade Islands, and Westheidesyllis splendida sp. nov. from Rocas Atoll. These two species belong to genera currently of uncertain affinities within the family, in both cases previously included in the Eusyllinae subfamily. Moreover, we provide updated identification keys for both genera to facilitate their future identification.
The genus Armillipora Quate is recorded for the first time in Ecuador, with a new geographical record for Armillipora selvica Quate, 1996 and the descriptions of two new species, namely Armillipora muyu sp. nov. and Armillipora imitata sp. nov., doubling the total number of species in the genus. In addition, we make available the first DNA barcodes for the genus, providing a sequence of the 5´-end of the cytochrome c oxidase subunit I (COI) gene for A. imitata, A. muyu, and, A. selvica. Moreover, we describe the second known female of the genus and we provide a taxonomical key for the known males of the world. Finally, we build Species Distribution Models and discuss the potential distribution of the genus in the Neotropical region.
The erasipterid Sinoerasipteron xiaheyanensis Nel & Huang gen. et sp. nov. from the Moscovian Tupo Formation in Xiaheyan locality (China), is described and illustrated. It is the sixth species of the odonatopteran griffenflies from this locality. This new discovery confirms the high diversity of these flying predators in the insect assemblage.
Six new species of the genus Rhaphidophora Serville, 1838 are described from China: R. hexagoniproctalis Wang, Di & He sp. nov., R. heterodentis Shen, Wang & He sp. nov., R. imbricofurca Shen, Wang & He sp. nov., R. glenoides Qin, Wang & He sp. nov., R. impressa Wang, Qin & He sp. nov., R. stenoterminata Zhang, Wang & He sp. nov. A key with previously described species from China is provided.
A contribution to the taxonomy of the genus Pelecium Kirby (Coleoptera: Carabidae: Peleciini)
(2024)
Pelecium Kirby, 1817 is a neotropical genus of flightless carabid beetles comprising 34 species, distributed from Panama to middle Argentina. Most species of Pelecium are known from short series and few localities, in some cases only from the holotype. Male and female abdominal terminalia are not described for the majority of the species, a situation that makes it difficult to describe new species or to study intraspecific variation. Here, we describe nine new species based on individuals from Brazil: Pelecium buckupi sp. nov., P. fistulosus sp. nov. and P. zaguryi sp. nov. from the Centre-West region, P. belloi sp. nov., P. chrissquirei sp. nov., P. straneoi sp. nov. and P. zophos sp. nov. from the Southeast region, and P. balli sp. nov. and P. grossii sp. nov. from the South region. We also provide new distributional records and descriptions of abdominal terminalia for twelve species: Pelecium atroviolaceum Straneo & Ball, 1989, P. bolivianum Straneo & Ball, 1989, P. cyanipes Kirby, 1817, P. helenae Straneo & Ball, 1989, P. laeve Chaudoir, 1854, P. negrei Straneo, 1962, P. drakei Quedenfeldt, 1890, P. punctatostriatum Straneo, 1970, P. purpureum Straneo, 1955, P. rotundipenne Schaum, 1860, P. striatum Straneo, 1955 and P. violaceum Brullé, 1838.
During exploratory surveys of the fungal diversity in Margalla Hills National Park, Islamabad, we collected a new species of the genus Hymenopellis R.H.Petersen. This is the second report of any species of this genus from Pakistan. Hymenopellis areolata F.Razzaq & Khalid sp. nov. is characterized by an areolate pileus, small basidiospores, and transitional pileipellis (hymeniderm and epithelium) with small pileocystidia. Molecular phylogenetic analyses of the nucleotide sequences of nrITS and nrLSU regions, and morphological data support the description of this new species. A comparison with other closely related species confirmed that the newly described species is distinct from others.
Unser Zusammenleben basiert auf normativen Ordnungen. Auch die Demokratie ist eine solche Ordnung. Ihre Regeln sind nicht statisch, sie können verändert, angepasst werden. Doch was, wenn die Menschen der Demokratie nicht mehr vertrauen? Darüber sprach »Forschung Frankfurt« mit Rainer Forst, Professor für politische Philosophie an der Goethe-Universität.
This paper reviews little-known species of the dysderid spider genera Dysdera Latreille, 1804, and Dysderella Dunin, 1992 based on specimens collected in the Caucasus, Middle East, and Central Asia. After combining molecular phylogeny of five mitochondrial and three nuclear genes with morphological evidence, Dysderella is proposed as a junior synonym of Dysdera. In addition, three species are described as new to science: D. jaegeri Bellvert & Dimitrov sp. nov., D. naouelae Bellvert & Dimitrov sp. nov., and D. kourosh Bellvert, Zamani & Dimitrov sp. nov. Four combinations are proposed: Dysdera caspica Dunin, 1990 comb. rev., Dysdera transcaspica Dunin & Fet, 1985 comb. rev., Dysdera elburzica (Zamani, Marusik & Szűts, 2023) comb. nov. and Dysdera sancticedri (Brignoli, 1978) comb. nov. (ex. Dasumia Thorell, 1875). Furthermore, we report a first record of D. festai Caporiacco, 1929 in Turkey and its male cheliceral polymorphism. Our results illustrate the deficiencies that undermine the current taxonomy of this genus. For example, many species are described based on only one or few specimens or limited locality data. The advancements in DNA sequencing technologies applied to museum specimens reduce the need for fieldwork collection and export of fresh specimens. This highlights the significance of museum collections for improving research in this field.

We present new and atypical host records for 78 species, subspecies, species-groups, and variants of spider wasps (Hymenoptera: Pompilidae) from North America and South America. The records are listed in modified taxonomic order following the Catalog of Hymenoptera in America North of Mexico, Volume 2, Apocrita (Aculeata) (Krombein 1979).

We propose several nomenclatural changes for taxa in the subfamily Cladodinae and the lampyrid tribes Cratomorphini, Lamprocerini, Lampyrini, Photinini, and Pleotomini in the subfamily Lampyrinae (Coleoptera: Lampyridae). We present evidence for the correct year of description of Calotrachelum flavolineatum Pic, 1941, Diaphanes lateapicalis breveapicalis Pic, 1954, Photinus conradti Pic, 1940, and all species described by Charles Émile Blanchard. Spellings are corrected for Diaphanes lateapicalis breveapicalis Pic, 1954, Diaphanes latipennis dartevillei Pic, 1952, Diaphanes longecarinatus Pic, 1955, Diaphanes moultoni latemarginatus Pic, 1938, Lampyris olivieriana von Heyden, 1890, and Photinus reductemarginalis Pic, 1941. We propose Lucidota puertoestrellaensis Keller and Martin nomen novum to replace Lucidota boliviana Pic, 1927, and Photinus laticollis brasiliensis Keller and Martin nomen novum for Photinus laticollis latior Pic, 1941. Seventy taxa described as variations or aberrations in the tribes Cratomorphini, Lamprocerini, Lampyrini, Photinini, and Pleotomini in the subfamily Lampyrinae by McDermott (1966), are evaluated to subspecies with their availability determined based on ICZN (1999: Article 45.6). Photinus motschulskyi Zaragoza-Caballero, Zurita-Garcia, and Ramírez-Ponce, 2023 is synonymized under Photinus intercalatus Gemminger, 1870. Lastly, we correct the type species of the genus Lucidina Gorham, 1833, and address the dates of publication for fireflies described by Blanchard.

The genus Lichnanthe Burmeister (Coleoptera: Scarabaeoidea: Glaphyridae) has been comprised of eight Nearctic species and contains the only New World members of their family. Here, two new species of arenicolous bumblebee scarabs are described from the central United States. The recent discovery of an undescribed Wyoming species led to the reevaluation of a dubious 134-year-old Nebraska Lichnanthe specimen, indicating that it also was an undescribed species. These two species, Lichnanthe brusti new species from central Wyoming and L. bruneri new species from central Nebraska are immediately distinguishable from all existing species of the genus by their square mandibles.

Anthrenus (Anthrenus) muehlei, a new species (Coleoptera: Dermestidae: Megatominae) from Iran
(2024)
A new species, Anthrenus muehlei Holloway and Herrmann (Coleoptera: Dermestidae: Megatominae), from Iran is described. Images of internal and external features are presented. Only female specimens were found and described, but the bursa copulatrix contains obvious sclerites enabling easy differentiation from all other known species from the Palaearctic A. pimpinellae complex. The possible function and taxonomic implication of the sclerites is mentioned.

Residual connections have been proposed as an architecture-based inductive bias to mitigate the problem of exploding and vanishing gradients and increased task performance in both feed-forward and recurrent networks (RNNs) when trained with the backpropagation algorithm. Yet, little is known about how residual connections in RNNs influence their dynamics and fading memory properties. Here, we introduce weakly coupled residual recurrent networks (WCRNNs) in which residual connections result in well-defined Lyapunov exponents and allow for studying properties of fading memory. We investigate how the residual connections of WCRNNs influence their performance, network dynamics, and memory properties on a set of benchmark tasks. We show that several distinct forms of residual connections yield effective inductive biases that result in increased network expressivity. In particular, those are residual connections that (i) result in network dynamics at the proximity of the edge of chaos, (ii) allow networks to capitalize on characteristic spectral properties of the data, and (iii) result in heterogeneous memory properties. In addition, we demonstrate how our results can be extended to non-linear residuals and introduce a weakly coupled residual initialization scheme that can be used for Elman RNNs.
Brecht zufolge birgt die Frage nach den Verpflichtungen der Kunst eine unauflösbare Dialektik: Kunst und politischer Zweck sind einander nicht äußerlich, ihre Beziehung ist nicht durch Konflikt oder gegenseitigen Ausschluss gekennzeichnet, sondern vielmehr durch das Versprechen schöpferischer Reibung und gegenseitiger Bereicherung. Dies entspricht nicht der Art und Weise, in der die Literaturwissenschaft traditionell über die Beziehung der Literatur zur Sphäre der Politik nachgedacht hat. Sie hat vielmehr dazu geneigt, den Versuch, Kunst als politische Arbeit zu begreifen, als Kategorienfehler zubetrachten - als eine von außen herangetragene Zumutung, die beiden schadet: der Kunst und der Politik. [...] Wenn wir verschüttete literaturgeschichtliche Genealogien wiederherstellen, um der theoretischen Untersuchung alternative Wege aufzuzeigen, orientieren wir uns an neueren Bemühungen, ausgewählte Episoden politisierten Schreibens nicht als literaturgeschichtliche Anomalien zu betrachten, sondern als Schlüsselmomente in der Konfiguration der Beziehung zwischen Literatur und Politik - als einflussreiche Epizentren interventionistischer Kunst, von denen aus Debatten über Literaturpolitik und Praktiken engagierten Schreibens in neue und global ausgedehnte Kontexte ausstrahlen können. Die von uns vorgeschlagene Periodisierung verbindet experimentell drei Perioden intensiv politisierter und aktivistischer Kunst und Schriftstellerei: die Zwischenkriegszeit, die langen 1960er Jahre und die Gegenwart. Damit sollen alternative Traditionen sichtbar gemacht werden, die Raymond Williams zufolge oft an den Rändern des Jahrhunderts zurückgelassen wurden. Diese Periodisierung verzichtet auch bewusst darauf, eine einzige oder eindeutige Geschichte politisierter Literatur nachzuzeichnen.
Let's call it Nachbarschaft
(2024)
Im Sommer 2023 zogen das ZfL, das ZAS und die gemeinsame Verwaltung der Geisteswissenschaftlichen Zentren Berlin aus der Schützenstraße in Berlin-Mitte nach Wilmersdorf. In dem an der Pariser Str. 1, Ecke Meierottostr. 8 neu errichteten Gebäude ACHTUNDEINS von Eike Becker_Architekten bespielen die Zentren nun insgesamt drei Etagen. Im Erdgeschoss befinden sich, von außen einsehbar, die Forschungsbibliotheken von ZfL und ZAS sowie der Eberhard-Lämmert-Saal. Während des Neujahrsempfangs, mit dem sich ZfL, ZAS und die GWZ am 11. Januar 2024 der unmittelbaren Nachbarschaft vorstellten, entstand die Idee zu dieser Glosse.
In a similar way to dramatic performances and plays, song lyrics establish a complex discourse structure whereby listeners are placed in a position to overhear ‘the pretence of a conversation constructed to convey the performer’s meaning’ (Nahajec 2019: 25; see also Short 1996: 169). In Taylor Swift’s songwriting, listeners are positioned not only to eavesdrop on the narratives presented but are also invited to conceptualise and enact particular roles and scenarios in the discourse. This paper offers a stylistic analysis of songwriting and narrative structure across Swift’s oeuvre to identify how disnarration strategies are used to build stories in her two sister albums written and produced during the Covid-19 pandemic, folklore (2020) and evermore (2020). Specifically, this study examines how disnarration characterises the albums’ narrators, establishes narrator-narratee relationships and invites listeners to adopt a participatory role in the meaning-making process. Through close analysis of four songs across the two albums, this paper builds on developing studies of the stylistics of songwriting (see West 2019) and argues that disnarration strategies foreground particular themes within the discourse, such as nostalgia, wistfulness and regret, and contribute to the fictionalisation and self-aware storytelling characteristic of these albums’ storyworlds.
The Federal Reserve has been publishing federal funds rate prescriptions from Taylor rules in its Monetary Policy Report since 2017. The signals from the rules aligned with Fed action on many occasions, but in some cases the Fed opted for a different route. This paper reviews the implications of the rules during the coronavirus pandemic and the subsequent inflation surge and derives projections for the future.
In 2020, the Fed took the negative prescribed rates, which were far below the effective lower bound on the nominal interest rate, as support for extensive and long-lasting quantitative easing. Yet, the calculations overstate the extent of the constraint, because they neglect the supply side effects of the pandemic.
The paper proposes a simple model-based adjustment to the resource gap used by the rules for 2020. In 2021, the rules clearly signaled the need for tightening because of the rise of inflation, yet the Fed waited until spring 2022 to raise the federal funds rate. With the decline of inflation over the course of 2023, the rules’ prescriptions have also come down. They fall below the actual federal funds rate target range in 2024. Several caveats concerning the projections of the interest rate prescriptions are discussed.
Although iron-based catalysts are regarded as a promising alternative to precious metal catalysts, their precise electronic structures during catalysis still pose challenges for computational descriptions. A particularly urgent question is the influence of the environment on the electronic structure, and how to describe this properly with computational methods. Here, we study an iron porphyrin chloride complex adsorbed on a graphene sheet using density functional theory calculations to detail how much the electronic structure is influenced by the presence of a graphene layer. Our results indicate that weak interactions due to van der Waals forces dominate between the porphyrin complex and graphene, and only a small amount of charge is transferred between the two entities. Furthermore, the interplay of the ligand field environment, strong p − d hybridization, and correlation effects within the complex are strongly involved in determining the spin state of the iron ion. By bridging molecular chemistry and solid state physics, this study provides first steps towards a joint analysis of the properties of iron-based catalysts from first principles.
Determining the structure and mechanisms of all individual functional modules of cells at high molecular detail has often been seen as equal to understanding how cells work. Recent technical advances have led to a flush of high-resolution structures of various macromolecular machines, but despite this wealth of detailed information, our understanding of cellular function remains incomplete. Here, we discuss present-day limitations of structural biology and highlight novel technologies that may enable us to analyze molecular functions directly inside cells. We predict that the progression toward structural cell biology will involve a shift toward conceptualizing a 4D virtual reality of cells using digital twins. These will capture cellular segments in a highly enriched molecular detail, include dynamic changes, and facilitate simulations of molecular processes, leading to novel and experimentally testable predictions. Transferring biological questions into algorithms that learn from the existing wealth of data and explore novel solutions may ultimately unveil how cells work.

Abstract
The European Commission's current efforts to launch the largest proposal to restrict per- and polyfluoroalkyl substances (PFAS) in history reflect the dire global plight of PFAS accumulation in the environment and their health impacts. While there are existing studies on PFAS research, there is a lack of comprehensive analysis that both covers the entire research period and provides deep insights into global research patterns, incentives, and barriers based on various parameters. We have been able to demonstrate the increasing interest in PFAS research, although citation numbers are declining prematurely. Policy regulations based on proving and establishing the toxicity of PFASs have stimulated research in developed countries and vice versa, with increasing emphasis on ecological aspects. China, in particular, is investing increasingly in PFAS research, but without defining or implementing regulations - with devastating effects. The separation of industrial and environmental research interests is clear, with little involvement of developing countries, even though their exposure to PFAS is devastating. It, therefore, requires increased globally networked and multidisciplinary approaches to address PFAS contamination challenges.
Motivated by the question of the impact of selective advantage in populations with skewed reproduction mechanisms, we study a Moran model with selection. We assume that there are two types of individuals, where the reproductive success of one type is larger than the other. The higher reproductive success may stem from either more frequent reproduction, or from larger numbers of offspring, and is encoded in a measure Λ for each of the two types. Λ-reproduction here means that a whole fraction of the population is replaced at a reproductive event. Our approach consists of constructing a Λ-asymmetric Moran model in which individuals of the two populations compete, rather than considering a Moran model for each population. Provided the measure are ordered stochastically, we can couple them. This allows us to construct the central object of this paper, the Λ−asymmetric ancestral selection graph, leading to a pathwise duality of the forward in time Λ-asymmetric Moran model with its ancestral process. We apply the ancestral selection graph in order to obtain scaling limits of the forward and backward processes, and note that the frequency process converges to the solution of an SDE with discontinuous paths. Finally, we derive a Griffiths representation for the generator of the SDE and use it to find a semi-explicit formula for the probability of fixation of the less beneficial of the two types.
IHMCIF: an extension of the PDBx/mmCIF data standard for integrative structure determination methods
(2024)
IHMCIF (github.com/ihmwg/IHMCIF) is a data information framework that supports archiving and disseminating macromolecular structures determined by integrative or hybrid modeling (IHM), and making them Findable, Accessible, Interoperable, and Reusable (FAIR). IHMCIF is an extension of the Protein Data Bank Exchange/macromolecular Crystallographic Information Framework (PDBx/mmCIF) that serves as the framework for the Protein Data Bank (PDB) to archive experimentally determined atomic structures of biological macromolecules and their complexes with one another and small molecule ligands (e.g., enzyme cofactors and drugs). IHMCIF serves as the foundational data standard for the PDB-Dev prototype system, developed for archiving and disseminating integrative structures. It utilizes a flexible data representation to describe integrative structures that span multiple spatiotemporal scales and structural states with definitions for restraints from a variety of experimental methods contributing to integrative structural biology. The IHMCIF extension was created with the benefit of considerable community input and recommendations gathered by the Worldwide Protein Data Bank (wwPDB) Task Force for Integrative or Hybrid Methods (wwpdb.org/task/hybrid). Herein, we describe the development of IHMCIF to support evolving methodologies and ongoing advancements in integrative structural biology. Ultimately, IHMCIF will facilitate the unification of PDB-Dev data and tools with the PDB archive so that integrative structures can be archived and disseminated through PDB.
The Russian invasion of Ukraine illustrates the increasingly judicialized nature of international relations and geopolitics. By viewing aspects of the invasion as illegal – in particular through the identification of war crimes and crimes against humanity – the international response draws attention to the political geographies of international criminal investigation. Human rights groups, academics, journalists, and open-source forensic investigations have joined forces to collect, evaluate and analyze the violent nature of war crimes. While similar shifts in evidence gathering have been observed in the case of the Bosnia-Herzegovina war and the Assad regime's violence against Syrian citizens, the use of evidence-gathering technologies and evidence-securing institutions in the case of Ukraine is distinctive. In this scholarly intervention we seek to illustrate the intimate geopolitics of evidence gathering by zooming in on two different elements that shape evidential procedures in Ukraine: i) the blurring of civilian/military boundaries; and ii) the challenges of access. By evaluating what is new and what is similar to previous war sites, we suggest that these two areas reflect a geopolitics of evidence gathering, highlighting its global-local intimacies. Both these areas are well positioned to foster new research on the (geo)legal nature of war crimes in political geography and beyond.
Studying the neural basis of human dynamic visual perception requires extensive experimental data to evaluate the large swathes of functionally diverse brain neural networks driven by perceiving visual events. Here, we introduce the BOLD Moments Dataset (BMD), a repository of whole-brain fMRI responses to over 1,000 short (3s) naturalistic video clips of visual events across ten human subjects. We use the videos’ extensive metadata to show how the brain represents word- and sentence-level descriptions of visual events and identify correlates of video memorability scores extending into the parietal cortex. Furthermore, we reveal a match in hierarchical processing between cortical regions of interest and video-computable deep neural networks, and we showcase that BMD successfully captures temporal dynamics of visual events at second resolution. With its rich metadata, BMD offers new perspectives and accelerates research on the human brain basis of visual event perception.
The ubiquitin (Ub) code denotes the complex Ub architectures, including Ub chains of different length, linkage-type and linkage combinations, which enable ubiquitination to control a wide range of protein fates. Although many linkage-specific interactors have been described, how interactors are able to decode more complex architectures is not fully understood. We conducted a Ub interactor screen, in humans and yeast, using Ub chains of varying length, as well as, homotypic and heterotypic branched chains of the two most abundant linkage types – K48- and K63-linked Ub. We identified some of the first K48/K63 branch-specific Ub interactors, including histone ADP-ribosyltransferase PARP10/ARTD10, E3 ligase UBR4 and huntingtin-interacting protein HIP1. Furthermore, we revealed the importance of chain length by identifying interactors with a preference for Ub3 over Ub2 chains, including Ub-directed endoprotease DDI2, autophagy receptor CCDC50 and p97-adaptor FAF1. Crucially, we compared datasets collected using two common DUB inhibitors – Chloroacetamide and N-ethylmaleimide. This revealed inhibitor-dependent interactors, highlighting the importance of inhibitor consideration during pulldown studies. This dataset is a key resource for understanding how the Ub code is read.
Zinc finger (ZnF) domains appear in a pool of structural contexts and despite their small size achieve varying target specificities, covering single-stranded and double-stranded DNA and RNA as well as proteins. Combined with other RNA-binding domains, ZnFs enhance affinity and specificity of RNA-binding proteins (RBPs). The ZnF-containing immunoregulatory RBP Roquin initiates mRNA decay, thereby controlling the adaptive immune system. Its unique ROQ domain shape-specifically recognizes stem-looped cis-elements in mRNA 3’-untranslated regions (UTR). The N-terminus of Roquin contains a RING domain for protein-protein interactions and a ZnF, which was suggested to play an essential role in RNA decay by Roquin. The ZnF domain boundaries, its RNA motif preference and its interplay with the ROQ domain have remained elusive, also driven by the lack of high-resolution data of the challenging protein. We provide the solution structure of the Roquin-1 ZnF and use an RBNS-NMR pipeline to show that the ZnF recognizes AU-rich elements (ARE). We systematically refine the contributions of adenines in a poly(U)-background to specific complex formation. With the simultaneous binding of ROQ and ZnF to a natural target transcript of Roquin, our study for the first time suggests how Roquin integrates RNA shape and sequence specificity through the ROQ-ZnF tandem.
G protein-coupled receptors (GPCRs) play a crucial role in modulating physiological responses and serve as the main drug target. Specifically, salmeterol and salbutamol which are used for the treatment of pulmonary diseases, exert their effects by activating the GPCR β2-adrenergic receptor (β2AR). In our study, we employed coarse-grained molecular dynamics simulations with the Martini 3 force field to investigate the dynamics of drug molecules in membranes in presence and absence of β2AR. Our simulations reveal that in more than 50% of the flip-flop events the drug molecules use the β2AR surface to permeate the membrane. The pathway along the GPCR surface is significantly more energetically favorable for the drug molecules, which was revealed by umbrella sampling simulations along spontaneous flip-flop pathways. Furthermore, we assessed the behavior of drugs with intracellular targets, such as kinase inhibitors, whose therapeutic efficacy could benefit from this observation. In summary, our results show that β2AR surface interactions can significantly enhance membrane permeation of drugs, emphasizing their potential for consideration in future drug development strategies.
Motivated by the question of the impact of selective advantage in populations with skewed reproduction mechanims, we study a Moran model with selection. We assume that there are two types of individuals, where the reproductive success of one type is larger than the other. The higher reproductive success may stem from either more frequent reproduction, or from larger numbers of offspring, and is encoded in a measure Λ for each of the two types. Our approach consists of constructing a Λ-asymmetric Moran model in which individuals of the two populations compete, rather than considering a Moran model for each population. Under certain conditions, that we call the "partial order of adaptation", we can couple these measures. This allows us to construct the central object of this paper, the Λ−asymmetric ancestral selection graph, leading to a pathwise duality of the forward in time Λ-asymmetric Moran model with its ancestral process. Interestingly, the construction also provides a connection to the theory of optimal transport. We apply the ancestral selection graph in order to obtain scaling limits of the forward and backward processes, and note that the frequency process converges to the solution of an SDE with discontinous paths. Finally, we derive a Griffiths representation for the generator of the SDE and use it to find a semi-explicit formula for the probability of fixation of the less beneficial of the two types.
The chenopodium aphid, Hayhurstia atriplicis (Linnaeus, 1761) (Hemiptera: Aphididae), is reported for the first time in Colombia. The aphid was found on the aerial parts of the quinoa plant, Chenopodium quinoa Willd. (Amaranthaceae), especially on the leaves, in five municipalities in the department of Cauca, Colombia. Brief information on its natural enemies, distribution and biology is provided. This is the only aphid in Colombia known to cause malformations on the leaves of quinoa plants. In South America, this aphid has been found previously only in Ecuador, where it was reported for the first time in 2023 based on specimens collected from 2019 to 2021. However, we report that H. atriplicis was likely introduced to Ecuador in the 2000s or earlier, based on a collection dated 2006 found in the United States National Museum of Natural History.

Three species of false click beetles (Coleoptera: Eucnemidae) are added to the Nearctic fauna. One new species, Isorhipis bicolor, is described from a small series collected in Florida, U.S.A. Eighteen specimens collected from Georgia were identified as Dyscharachthis amplicollis (Fleutiaux), new U.S.A. records for a species previously taken from Japan and Southeast Asia. Examination of a series of eucnemids collected by Kyle Schnepp in Florida allowed me to revisit the Deltometopus fauna in eastern North America. Antennal structures present in a series of male specimens in the loan and past examined specimens are definitive enough to resurrect Deltometopus ereptus Bonvouloir, status restored, from synonymy with Deltometopus amoenicornis (Say). Species identification keys are provided for Deltometopus Bonvouloir and Isorhipis Boisduval and Lacordaire in the Nearctic region. Diagnostic differences are briefly noted for each of the three newly added species found in the United States. Images of three species and the related D. amoenicornis are provided.

Im November durfte er seinen 77. Geburtstag feiern, von Ruhestand ist aber noch keine Spur. Gerade bereitet er sich in seinem Büro über der Neuen Mensa am alten Campus in Bockenheim mit großem Elan auf die nächste Seminarsitzung vor. »Die Lehre an der Universität wie an Fachhochschulen war mir nie eine Last. Ich habe versucht, die Studierenden zu motivieren oder bei Bedarf gar zu provozieren, um zu kommunizieren, weil wir alle viel mehr von gegenseitigem Austausch haben«, sagt Ludwig Salgo. Zahlreiche Studierende der Sozialen Arbeit, aus der Rechtswissenschaft, aber auch aus der Erziehungswissenschaft haben seine Veranstaltungen besucht; etliche Juristinnen und Juristen haben bei ihm promoviert, sich für die pädagogische oder juristische Laufbahn qualifiziert. Sein zentrales Thema in Forschung und Lehre: das Verhältnis Eltern-Kind-Staat. Anfang 2012 ging er in den Ruhestand, doch die Lehre blieb vorerst seine große Passion. Jetzt beendet er seine Seniorprofessur an der Goethe-Universität zum Semesterende nach zehn Jahren: »Nun ist es genug«, sagt er. In der Fortbildung für Jugendämter, Verfahrensbeistände und Juristen, auch in Stiftungen und Verbänden, hier vor allem im Kinderschutzbund in Frankfurt, möchte er weiterhin aktiv bleiben, auch um für das Thema Kindeswohl zu sensibilisieren. Dass er dann mehr Zeit für seine große Leidenschaft haben wird, freut ihn: »Ich leide an der Melomanie«, sagt der passionierte Freund klassischer Musik. »Wie Nietzsche treffenderweise einmal bemerkt hat, wäre das Leben ohne Musik ein Irrtum.«
We describe a new species of karst-dwelling pitviper from Chumphon Province of Peninsular Thailand, in the Isthmus of Kra, based on morphological and molecular data (2427 bp from cyt b, ND4 and 16S rRNA mitochondrial DNA genes). Morphologically, Trimeresurus kraensis sp. nov. is distinguished from other congeners by the following combination of morphological characters: a dark/bottle-green dorsum with reddish-brown or purple crossbands; pale green venter lacking dark dots; stripes present on the lateral sides of the ventrals; internasals generally in contact; one large supraocular scale on each side of the head; iris pale copper; tail brown with dark purplish-brown crossbars; dorsal scales in 21–21–15 rows; ventral scales 167 in a single male, 169–171 in females; subcaudal scales 62 in a single male, 52–54 in females, all paired. White vertebral spots present in males, located on approximately every two or four dorsal scales; dark brown spots forming discontinuous pattern present on 1–3 lateral dorsal scale rows; males with reddish-brown postocular stripe with jagged edges. The new species differs from the morphologically similar species Trimeresurus venustus s. str. by a notable divergence in cytochrome b mitochondrial DNA gene sequences (p = 5.9%).
In the vast abyssal plains northwest of Iceland, white glass sponges of the genus Caulophacus Schulze, 1886 were inhabited by reddish Bythocaris G.O. Sars, 1870 shrimps and pinkish amphipods. After in situ observations at 3700 m depth, in -1°C waters by a remotely operated vehicle, members of this assemblage were collected and preserved for molecular studies. Based on integrative taxonomic analyses, the amphipods were identified as a new species of the genus Halirages Boeck, 1871 – Halirages spongiae sp. nov. Lörz, Nack & Tandberg –, as described in detail below. Part of our integrative approach was to establish reference DNA barcodes for known species of Halirages. However, our investigation of material of Calliopiidae G.O. Sars, 1895 collected around Iceland and Norway revealed slight morphological discrepancies in all the described species of Halirages. Except for Halirages fulvocinctus (M. Sars, 1858), none of the encountered specimens of Calliopiidae fully matched a current species description. We illuminate the morphological characteristics of nine operational taxonomic units, which also represented clades in COI and 28S. We set the Icelandic samples in the context of Halirages from Canada and Norway. A key to the world species of Halirages is provided.
Highlights
• Seed size mediates seedling recruitment in tropical forests and pastures.
• Large-seeded species recruited better than small-seeded species in the forest.
• Recruitment of large-seeded species in pastures was limited by surface temperature.
• Large-seeded species should be protected against drought in regenerating pastures.
Abstract
Seedling recruitment is a key process of plant regeneration that often depends on plant functional traits, such as seed size. To optimize forest restoration efforts, we need to better understand how seedling recruitment of different seed sizes varies along environmental gradients with strong variation in abiotic and biotic factors. To understand these interacting effects, we conducted a sowing experiment with different-sized seeds in forests and pastures in the tropical mountains of southern Ecuador. We quantified seedling recruitment in relation to temperature, soil moisture and biotic pressures. We sowed seeds of five tree species of varying seed size at three elevations (1000, 2000 and 3000 m a.s.l.) in primary forest and pastures. We tested (1) how habitat type influences the recruitment of seedlings belonging to three small- and two large-seeded species, and (2) how abiotic and biotic factors limit seedling recruitment of species with different seed sizes. We found that seedlings of the two large-seeded species recruited better than seedlings of the three small-seeded species, but only in the forest habitat. Seedling recruitment of large seeds was primarily limited by high surface temperature, which explains lower recruitment of large seeds in pastures compared to forests. Our study shows that seed size can be a key trait mediating variability in seedling recruitment in tropical ecosystems. We conclude that restoration measures should aim to mitigate extreme temperatures in tropical pastures to aid the natural regeneration of large-seeded tree species.

Abstract
This paper presents and compares Newton-based methods from the applied mathematics literature for solving the matrix quadratic that underlies the recursive solution of linear DSGE models. The methods are compared using nearly 100 different models from the Macroeconomic Model Data Base (MMB) and different parameterizations of the monetary policy rule in the medium-scale New Keynesian model of Smets and Wouters (2007) iteratively. We find that Newton-based methods compare favorably in solving DSGE models, providing higher accuracy as measured by the forward error of the solution at a comparable computation burden. The methods, however, suffer from their inability to guarantee convergence to a particular, e.g. unique stable, solution, but their iterative procedures lend themselves to refining solutions either from different methods or parameterizations.
The hierarchical feature regression (HFR) is a novel graph-based regularized regression estimator, which mobilizes insights from the domains of machine learning and graph theory to estimate robust parameters for a linear regression. The estimator constructs a supervised feature graph that decomposes parameters along its edges, adjusting first for common variation and successively incorporating idiosyncratic patterns into the fitting process. The graph structure has the effect of shrinking parameters towards group targets, where the extent of shrinkage is governed by a hyperparameter, and group compositions as well as shrinkage targets are determined endogenously. The method offers rich resources for the visual exploration of the latent effect structure in the data, and demonstrates good predictive accuracy and versatility when compared to a panel of commonly used regularization techniques across a range of empirical and simulated regression tasks.

The ALICE Collaboration reports a differential measurement of inclusive jet suppression using pp and Pb−Pb collision data at a center-of-mass energy per nucleon-nucleon collision sNN−−−√=5.02 TeV. Charged-particle jets are reconstructed using the anti-kT algorithm with resolution parameters R= 0.2, 0.3, 0.4, 0.5, and 0.6 in pp collisions and R= 0.2, 0.4, 0.6 in central (0−10%), semi-central (30−50%), and peripheral (60−80%) Pb−Pb collisions. A novel approach based on machine learning is employed to mitigate the influence of jet background. This enables measurements of inclusive jet suppression in new regions of phase space, including down to the lowest jet pT≥40 GeV/c at R=0.6 in central Pb−Pb collisions. This is an important step for discriminating different models of jet quenching in the quark-gluon plasma. The transverse momentum spectra, nuclear modification factors, derived cross section, and nuclear modification factor ratios for different jet resolution parameters of charged-particle jets are presented and compared to model predictions. A mild dependence of the nuclear modification factor ratios on collision centrality and resolution parameter is observed. The results are compared to a variety of jet-quenching models with varying levels of agreement.
We document the individual willingness to act against climate change and study the role of social norms in a large sample of US adults. Individual beliefs about social norms positively predict pro-climate donations, comparable in strength to universal moral values and economic preferences such as patience and reciprocity. However, we document systematic misperceptions of social norms. Respondents vastly underestimate the prevalence of climate-friendly behaviors and norms. Correcting these misperceptions in an experiment causally raises individual willingness to act against climate change as well as individual support for climate policies. The effects are strongest for individuals who are skeptical about the existence and threat of global warming.

Pseudococcus longispinus (Targioni-Tozzetti) (Hemiptera: Pseudococcidae) is a widely-distributed pest that feeds on many economically important hosts, particularly tropical fruits and ornamentals. The potential distribution of this mealybug pest in South Korea remains a primary concern because of its high incidence of interceptions screened during inspection. Hence, this species prompted a modelling effort to assess its potential risk of introduction. Potential risk maps were developed for this pest with a CLIMEX model based on occurrence records under environmental data. The potential distribution of these pests in South Korea in the 2020s, 2050s and 2090s was projected based on the RCP 8.5 climate change scenario. Results showed that P. longispinus has little potential for invasion in the outdoor environment of South Korea due to high cold stress in the 2020s. However, some locations in Jejudo were predicted to be marginally suitable under future climate factors. In that respect, the results of this model prediction could be used to prepare a risk-based surveying program that improves the probability of detecting early P. longispinus populations.

• High resolution profile of C. pipiens' sugar diet has been obtained using UHPLC-MS.
• Artificial feeding using ornamental plants provides similar sugar profiles as observed in field collected mosquitoes.
• Metabolomic profiling found secondary metabolites and pollutants of anthropogenic use.
Abstract: Culex pipiens (Linnaeus, 1758) mosquitoes search plant sources of sugars to cope with the energetic demand of various physiological processes. The crop as part of the digestive system is devoted to the storage of sugar-based meal obtained from various nectars sources. The profiling of sugars and metabolites in the Culex pipiens’ crop is scarce, and only few studies used Liquid Chromatography – Mass Spectrometry (LC-MS), which provides broad detection for biomonitoring environmental substances and even contaminants in the sugar diet of mosquitoes populations.
Therefore, sugar and metabolite profiling were performed on crops obtained from mosquitoes exposed to plant nectar under laboratory or natural conditions by Ultra High-Performance LC-MS (UHPLC-MS). This method allowed us a precise quantitative and qualitative identification of sugar diet and associated environmental compounds in the crop of the mosquito C. pipiens. Under laboratory condition, mosquitoes were allowed to feed on either glucose solution, commercially-available flowers or field collected flowers. In addition, we collected mosquitoes from the field to compare those crop metabolomes with metabolome patterns occurring after nectar feeding in the lab.
The sugar quantities and quality obtained from the crops of mosquitoes collected in the field were similar to those crops obtained from mosquitoes that fed on commercially-available flowers and from field collected flowers with a limit of detection of 10 μg/L for sucrose, glucose and sucrose. Next to sugar compounds, we identified 2 types of amino acids, 12 natural products, and 9 pesticides.
Next to the diversity of sugar compounds, we could confirm that secondary metabolites and environmental pollutants are typically up taken from floral nectar sources by C. pipiens. The in-depth knowledge on mosquito–plant interactions may inspire the development and further optimization of mosquito trap systems and arboviral surveillance systems.

Members of the genus Centris Fabricius (Hymenoptera: Apoidea: Anthophila) constitute a significant component of the Neotropical (including insular) bee fauna, exhibiting high species richness, a moderate to large body size, and extensive interactions with various important plant groups. Females of most species possess specialized morphology adapted for collecting oils from flowers. This study documents the presence of the genus in Cuba, recognizing six species: C. aethiops Cresson, C. cornuta Cresson, C. fulviventris Cresson, C. poecila Lepeletier, C. taina Genaro and Breto new species, and C. tarsata F. Smith. Detailed information is provided for each species, encompassing a diagnosis, natural history, floral associations, seasonal occurrence, and distribution. Centris taina new species is described from Cuba, based on both sexes, which were previously misidentified as C. versicolor (Fabr.) for females and C. fasciatus F. Smith for males due to sexual dimorphism. Centris tarsata is reported as a new national record for Cuba, possibly introduced by humans from South America and now established and widely distributed across the entire island. A key to differentiate the Cuban species of Centris is presented.

The two-particle momentum correlation functions between charm mesons (D∗± and D±) and charged light-flavor mesons (π± and K±) in all charge-combinations are measured for the first time by the ALICE Collaboration in high-multiplicity proton-proton collisions at a center-of-mass energy of s√=13 TeV. For DK and D∗K pairs, the experimental results are in agreement with theoretical predictions of the residual strong interaction based on quantum chromodynamics calculations on the lattice and chiral effective field theory. In the case of Dπ and D∗π pairs, tension between the calculations including strong interactions and the measurement is observed. For all particle pairs, the data can be adequately described by Coulomb interaction only, indicating a shallow interaction between charm and light-flavor mesons. Finally, the scattering lengths governing the residual strong interaction of the Dπ and D∗π systems are determined by fitting the experimental correlation functions with a model that employs a Gaussian potential. The extracted values are small and compatible with zero.
