Recently, the first part of the morphological revision of the Southeast Asian water monitor lizards of the Varanus salvator (Laurenti, 1768) species group provided a taxonomic overview over the members of this successful and widespread species complex (Koch et al. 2007). There, the Philippine taxa marmoratus, nuchalis and cumingi were reelevated to species status due to diagnostic morphological characteristics, e.g. significantly enlarged scales on the neck region. In this second part of the ongoing revision, these three species are re-investigated using additional voucher specimens and advanced statistical techniques including canonical variates analysis and principal component analysis. Our new investigations indicate that V. marmoratus represents a composite species, comprising at least three distinct taxa. Hence, the populations of the Sulu Archipelago (Tawi-Tawi Island) and those of the Palawan region are described as new species, viz. Varanus rasmusseni sp. nov. and V. palawanensis sp. nov., respectively. The allopatric island populations of V. cumingi inhabiting Samar, Leyte, and Bohol (the East Visayan subregion) show characteristic and geographically correlated colour patterns distinct from the type locality Mindanao (the second subregion of Greater Mindanao), warranting subspecific partition of this species. The new subspecies is named V. cumingi samarensis ssp. nov. In contrast, the taxonomic status of V. nuchalis remained unchanged, although this species shows some considerable variation in colour pattern. The systematic chapters are supplemented with notes about biology and conservation status. The hitherto underestimated diversity and zoogeography of Philippine water monitors is discussed in the light of Pleistocene sea level fluctuations. Finally, we introduce a scenario for the evolution and spread of Southeast Asian water monitor lizards and provide an identification key for the Philippine members of the V. salvatoI' complex.
The re-emergence of tuberculosis in its present-day manifestations - single, multiple and extensive drug-resistant forms and as HIV-TB coinfections - has resulted in renewed research on fundamental questions such as the nature of the organism itself, Mycobacterium tuberculosis, the molecular basis of its pathogenesis, definition of the immunological response in animal models and humans, and development of new intervention strategies such as vaccines and drugs. Foremost among these developments has been the precise chemical definition of the complex and distinctive cell wall of M. tuberculosis, elucidation of the relevant pathways and underlying genetics responsible for the synthesis of the hallmark moieties of the tubercle bacillus such as the mycolic acid-arabinogalactan-peptidoglycan complex, the phthiocerol- and trehalose-containing effector lipids, the phosphatidylinositol-containing mannosides, lipomannosides and lipoarabinomannosides, major immunomodulators, and others. In this review, the laboratory personnel who have been the focal point of some to these developments review recent progress towards a comprehensive understanding of the basic physiology and functions of the cell wall of M. tuberculosis.
An annotated checklist and bibliography of 197 species (representing 78 genera and 26 families) of non-marine polychaetes of the world is presented, including synonymies, information on ecology, distribution, habitat, and references to the taxonomic and biological literature. Over half (57%) of the checklist species are represented by just three families as follows: Nereididae (61 species including Namanereis, Namalycastis, Neanthes and Hediste), Aeolosomatidae (27 species, mostly Aeolosoma) and Sabellidae (24 species including Caobangia and Manayunkia). Other well-represented taxa are the epizoic histriobdel1id Stratiodrilus (11 species), the inland-sea-specialist ampharetid Hypania and related genera (5 species), and the freshwater-tolerant spionid Marenzelleria (5 species). One new combination is proposed for the nereidid Nereis tenuipalpa Pflugfelder, 1933, viz. Paraleonnates tenuipalpa n. comb.
The Invertebrate section of the Museum of Zoology QCAZ at the Pontifical Catholic University of Ecuador in Quito maintains nearly two million curated specimens, and comprises Ecuador's largest collection of native taxa. We review 1902 type specimens from 6 subspecies and 320 species in 121 genera and 42 families, currently kept in the Museum. The list includes 116 holotypes, 10 allotypes, 1774 paratypes and 2 neoparatypes. The collection of type specimens is particularly strong in the Coleoptera (family Carabidae and Staphylinidae) and Hymenoptera. However, other insect orders such as Diptera and Lepidoptera and non-insect arthropods such as Acari, Aranea and Scorpiones, are moderately represented in the collection. This report provides original data from labels of every type specimen record. An analysis of the geographic distribution of type localities showed that collection sites are clustered geographically with most of them found. towards the northern region of Ecuador, in Pichincha, Cotopaxi and Napo provinces. Sites are mainly located in highly accessible areas near highways and towns. Localities with a high number of type species include the cloud forest reserve Bosque Integral Otonga and Parque Nacional Yasunf in the Amazon rainforest near PUCE's Yasuni Scientific Station. Type localities are not well represented in the Ecuadorian National System of Protected Areas. Future fieldwork Sllould include. localities in the southern region of Ecuador but also target less accessible areas not located near highways or towns. We discuss the value of the collection as a source of information for conservation and biodiversity policies in Ecuador.
Arthropods use fluid medium motion-sensing filiform hairs on their exoskeleton to detect aerodynamic or hydrodynamic stimuli in their surroundings that affect their behaviour. The hairs, often of different lengths and organized in groups or arrays, respond to particular fluid motion amplitudes and frequencies produced by prey, predators, or conspecifics, even in the presence of background noise peculiar to the environment. While long known to biologists and experimentally investigated by them, it is only relatively recently that comprehensive physical-mathematical models have emerged offering an alternative methodology for investigating the biomechanics of filiform hair motion. These models have been developed and applied to quantitatively predict the performance characteristics of filiform hairs in air and water as a function of the relevant parameters that affect their physical behaviour. They even allow the exploration of possible biological evolutionary paths for filiform hair changes resulting from physical selection pressures. In this chapter we review the state of knowledge of filiform hair biomechanics and discuss two physical-mathematical models to predict hair dynamical behaviour. One modelling approach is analytically exact, serving for quantitative purposes, while the other, derived from it, is approximate, serving for qualitative guidance concerning the parameter dependencies of hair motion. Using these models we look in turn at the influence of these parameters and the fluid media physical properties on hair motion, including the possibility of medium-facilitated viscous coupling between hairs. The models point to areas where data is currently lacking and future research could be focused. In addition, new results are presented pertaining to transient tlows. We qualitatively explore the possibility of an overlapping water-air niches adaptation potential that may explain how, over many generations, the filiform hairs of an arthropod living in water could have evolved to function in air. Because flow-sensing hairs have served to inspire corresponding artificial medium motion microsensors, we discuss recent advances in this area. Significant challenges remain to be overcome, especially with respect to the materials and fabrication techniques used. In spite of the impressive technological advances made, nature still remains unrivalled.
Die Gattung Phormictopuswurde im Jahre 1901 von POCOCK aufgestellt. In seine neue Gattung nahm er als Typusart Mygale cancerides LATREILLE, 1806 von der Insel Hispaniola auf, dazu kam Lasiodora cautus AUSSERER, 1875, eine Art, die ohne Angabe des locus typicus beschrieben worden war. Bisher waren 14 Arten und 2 Unterarten bekannt, von denen 5 aus Südamerika stammen. Die vorliegende Arbeit reduziert die Artenzahl auf 12, wobei 5 neue Arten beschrieben und 4 synonymisiert, 3 zu nomina dubia (Typus verschollen), und 3 "incertae sedis" (in andere Gattungen gehörig) erklärt werden.
The taxonomy, diversity, and distribution of the aquatic insect order Trichoptera, caddisflies, are reviewed. The order is among the most important and diverse of all aquatic taxa. Larvae are vital participants in aquatic food webs and their presence and relative abundance are used in the biological assessment and monitoring of water quality. The species described by Linnaeus are listed. The morphology of all life history stages (adults, larvae, and pupae) is diagnosed and major features of the anatomy are illustrated. Major components of life history and biology are summarized. A discussion of phylogenetic studies within the order is presented, including higher classification of the suborders and superfamilies, based on recent literature. Synopses of each of 45 families are presented, including the taxonomic history of the family, a list of all known genera in each family, their general distribution and relative species diversity, and a short overview of family-level biological features. The order contains 600 genera, and approximately 13,000 species.
Lepidoptera phylogeny and systematics : the state of inventorying moth and butterfly diversity
(2007)
The currently recognized robust support for the monophyly of the Lepidoptera (and the superorder Amphiesmenoptera comprising Lepidoptera + Trichoptera) is outlined, and the phylogeny of the principal lineages within the order is reviewed succinctly. The state of the taxonomic inventory of Lepidoptera is discussed separately for ‘micro-moths’, ‘macro-moths’ and butterflies, three assemblages on which work has followed historically somewhat different paths. While currently there are about 160,000 described species of Lepidoptera, the total number of extant species is estimated to be around half a million. On average, just over one thousand new species of Lepidoptera have been described annually in recent years. Allowing for the new synonyms simultaneously established, the net increase in species numbers still exceeds 800/year. Most of the additions are foreseeable in the micro-moth grade, but even for butterflies ca 100 species are added annually. Examples of particularly interesting new high-rank taxa that have been described (or whose significance has become realized) since the middle of the 20th century include the non-glossatan lineages represented by Agathiphaga and Heterobathmia and the heteroneuran families Andesianidae, Palaephatidae, Hedylidae and Micronoctuidae. Some thoughts on how present and future systematic lepidopterology might be prioritised are presented.
High-performance liquid chromatography (HPLC) has proved extremely versatile over the past 25 yr for the isolation and punfication of peptides varying widely in their sources, quantity and complexity. This article covers the major modes of HPLC utilized for peptides (size-exclusion, ion-exchange, and reversed-phase), as well as demonstrating the potential of a novel mixed-mode hydrophilic interaction/cation-exchange approach developed in this laboratory. In addition to the value of these HPLC modes for peptide separations, the value of various HPLC techniques for structural characterization of peptides and proteins will be addressed, e.g., assessment of oligomerization state of peptideslproteins by sizeexclusion chromatography and monitoring the hydrophilicitykydrophobicity of amphipathic cr-helical peptides, a vital precursor Tor the development of novel antimicrobial peptides. The value of capillary electrophoresis for peptide separations is also demonstrated. Preparative reversed-phase chromatography purification protocols for sample loads of up to 200 mg on analytical columns and instrumentation are introduced for both peptides and recombinant proteins. Key Words: Peptides; proteins; size-exclusion chromatography (SEC); anion-exchange chromatography (AEX); cation-exchange chromatography (CEX); mixed-mode hydrophilic interaction chromatography (HIL1C)/cation-exchange chromatography (CEX); reversed-phase high-performance liquid chromatography (RP-HPLC); preparative RP-HPLC of peptides and proteins; amino acid side-chain hydrophilicitylhydrophobicity coefficients; amino acid U-helical propensity values; amino acid side-chain stability coefficients
Schlüssel zur Bestiminung europäischer Boletales mit Röhren werden vorgestellt. Der Artenschlüssel ist großteils nir Bestimmung von Frischmaterial angelegt. Die Schlüssel zu den Familien und Gattungen sowie die Gattungsdiagnosen sind auf Europa bezogen und müßten in weltweiter Sicht noch erweitert werden. Im Schlüssel wurden einige in den letzten Jahren vorgcnoinmenen Neukombinationen und Synonymisierungen nicht übernommen. Für die nunmehr in Xerocomus integrierte Gattung Phylloporus wird die Schaffung einer Untergattung vorgeschlagen. Auch eine neue Sektion, eine neue Art und einige neue Kombinationen werden vorgeschlagen.
A systematic revision of the genus Dichaeu (Orchidaceae) in Costa Rica is presented. The taxonomic history of the genus and its phylogenetic position are discussed, with emphasis on infragenenc grouping. Characters of vegetative and floral morphology are treated, and their taxonoiilic significance is discussed. Twenty-nine Dichnea taxa are recognized for the flora of Costa Rica, and a key to species is provided. Each taxon is described on the basis of Costa Rican material, illustrated in a composite plate, and its distribution in the country is assessed. Distribution maps for all the taxa are given. Overall distribution, derivation of name, notes on species ecology, and diagnostic features are presented for each taxon. Lectotypes are selectcd for D. acostae Schltr., D. acroblephara Schltr., D. amparoana Schltr., D. costaricensis Schltr., D. dammeriana Kraenzl., D. lycopodioides Rchb. f. ex Kraenzl., D. poicillantha Schltr., D. selaginella Schltr., D. tuercklheimii Schltr., Epidendrum echinocarpon Sw., and E. trichocarpon Sw. A new species, D. gomez-lauritoi, is described and illustrated from the wet Caribbean plains of central Costa Rica.
Techniques for collecting, handling, preparing, storing and examining small molluscan specimens
(2007)
Micromolluscs are small-sized molluscs (< 5 mm), and include the great majority of undescribed molluscan taxa. Such species require special collecting, sorting and handling techniques and different storage requirements to those routinely used for larger specimens. Similarly, the preparation of shells, opercula, radulae and animals poses some challenges for scanning electron microscopy (SEM). An overview of experiences with various techniques is presented, both positive and negative. Issues discussed include those relating to storage of dry specimens and interaction of specimens with glass, gelatine and paper products, handling techniques and storage in various fluids. Techniques for cleaning shells for SEM are described and compared, as well as those for radular extraction. The interactions of chemicals used for the dissolution of tissue with calcareous micromolluscs are described. Methods for handling and mounting small radulae for SEM are detailed and brief guides to SEM and light photography are given. An appendix listing details of frequently-used chemicals is provided.
The former and current distribution of the quokka, Setortix brachyurus, was mapped from published and all available unpublished records. At the time of European settlement the quokka was widespread and abundant and its distribution encompassed an area of approximatelyThe former and current distribution of the quokka, Setortix brachyurus, was mapped from published and all available unpublished records. At the time of European settlement the quokka was widespread and abundant and its distribution encompassed an area of approximately 41 200 km2 of south-west Western Australia inclusive of two offshore islands, Bald Island and Rottnest Island. Historical reports indicated an extensive population decline occurred in the 1930s. The decline continued, with a previously undocumented decline apparent in the period from 1980 to 1992. However, this decline may be an artefact of the time scales used for mapping and may well equate with a previously reported decline lor a suite of south -west mammals in the 1970s. By 1992 the quokka´s distribution had been reduced to an area of approximately 17800 km2. An increased awareness of the presence of the quokka on the mainland has resulted in numerous reportings of quokka presence since 1992, has confimled the existence of several populations at the northern extent of the quokka´´s known geographic range and indicated the cmrent, 2005, distribution to be similar to that in 1992. However, survey and population estimates at six of these mainland locations from the northem jarrah forest indicated low abundance. There have been no population estimates elsewhere on the mainland. Two populations have been reported tiom the Swan Coastal Plain, but neither has been confirmed extant. Predation by the introduced fox, Vulpes vulpes, is implicated as a major cause of the quokka´s initial decline, while ongoing predation, habitat destruction and modification through altered tire regimes have contributed to the continued decline. Specific conservation management actions are recommended, namely: (i) Implementing an active adaptive management program in the northern jarrah forest to determine quokka population response to habitat manipulation through the use of fIre, fox baiting and pig control; (ii) Surveying the Stirling fumge and Green Range populations with emphasis placed on determining population size and population genetic structure; (iii) Surveying the reported occurrences from the Swan Coastal Plain, with emphasis on unambiguously determining presence. If confirmed, priority should he directed to assessing population size and determining the management requirements to ensure persistence of the population; (iv) Surveying southem forest and south coast populations to assess quokka population size, the extent of movement between sllbpopulations and assessment of the range of habitat types used by quokkas. The latter should be combined with spatial analyses of known extant populations and suitable and potentially suitable habitat; (v) Determining the role of tire in establishing and maintaining preferred habitat of southern forest and south coast populations; and (vi) Establishing a program to assess the potential effects from management operations.
Presented herein is the first morphological analysis of turtle relationships to examine the monophyly of many turtle groups by using only single species as terminals and by integrating a large number of primitive fossil taxa. The data matrix consists of 136 osteological parsimony informative characters with 169 derived character states for 45 fossil and 22 living species of the clade TESTUDINATA. The results corroborate the monophyly of a large number of previously hypothesized clades, but refute the accepted hypothesis regarding the basal split of living turtles. In particular, the primitive turdes Proterochersis robusta, Kayentachelys aprix, Mongolochelys efremovi, Meiolania platyceps, and Kallokibotion bajazidi are removed from their current position as crown turtles and placed along the phylogenetic stem of this clade. The age of the turtle crown is thereby adjusted from the Late Triassic to the Late Jurassic, which is relevant to testing molecular clock hypotheses. This revised topology has important implications for the evolution of several character complexes, because it implies that the common ancestor of all living turtles must have had a partially braced brain case and a primitive trochlear mechanism. Other noteworthy conclusions include the tentative exclusion of protostegids from CHELONIOIDEA, the placement of Platysternon megacephalum outside of CHELYDRIDAE, and the tentative interpretation of Sandownia harrisi as a basal eucryptodire.
Die 4. Fassung der Roten Liste der Brutvögel Deutschlands wurde durch das "Nationale Gremium Rote Liste Vögel" erarbeitet, in dem die wissenschaftlichen Institutionen der Ornithologie und Avifaunistik in Deutschland vertreten sind. Die Rote Liste ersetzt die 3. Fassung aus dem Jahr 2002 (BAUER et al. 2002); sie wurde erstmalig nach dem für alle Tier- und Pflanzenartengruppen sowie den Pilzen in Deutschland entwickelten Kriterienschema (5. LUDWIG et al. 2007) erarbeitet. Somit wird ein direkter Vergleich der Gefährdungssituation zwischen diesen Gruppen ermöglicht. Bestandsgröße, kurzfristiger (25 Jahre) und langfristiger (50-150 Jahre) Bestandstrend sind die wichtigsten Parameter zur Gefahrdungseinstufung der einzelnen Arten. Zusätzlich wurde jeweils die Wirksamkeit von Risikofaktoren artspezifisch identifiziert und berücksichtigt. Alle Einstufungen werden transparent vorgenommen und in der Anhangsliste publiziert. Der Dachverband Deutscher Avifaunisten (DDA) hat zur Erstellung der Datengrundlagen mit Stand 2005 für die Gefahrdungseinstufung ein neues Abfrageschema entwickelt, in dem die relevanten Informationen aus den nationalen Vogelmonitoring-Programmen aufgearbeitet und als Hintergrunddaten für die Einschätzungen von Bestandstrend und -größe auf Landesebene bereitgestellt wurden. Dadurch gewinnen die Einstufungen an Verlässlichkeit und Nachvollziehbarkeit. Der langfristige Trend wurde vom "Nationalen Gremium Rote Liste Vogel" ermittelt. Vor der Einstufung der Brutvogelarten wurde je Art eine Statuszuordnung vorgenommen, von denen nur die regelmäßig brütenden einheimischen Arten den weiteren Weg der Rote Liste-Erstellung durchlaufen. In der Roten Liste 2007 werden insgesamt 260 regelmäßige einheimische Brutvogelarten in Deutschland berücksichtigt, 25 weitere Arten brüteten nur unregelmäßig ('vermehrungsgäste': Status II), zudem wurden 29 Neozoen-Arten ermittelt (Status III), von denen 20 regelmäßig brüten. Dies ergibt zusammen 314 Arten, die höchste Zahl an Brutvogelarten, die je für eine Rote Liste zu Grunde gelegt wurde. Insgesamt befinden sich 110 regelmäßige Brutvogelarten in den Kategorien der Roten Liste 2007 (0 = ausgestorben, 1 = vom Aussterben bedroht, 2 :: stark gefährdet, 3 :: gefährdet und R = extrem selten), das entspricht 42,3 % der Arten, was einer minimal geringeren Gefahrdungsquote gegenüber der Vorgängerliste entspricht. Erfreulich ist, dass mit dem Bruchwasserläufer und dem Steinrötel zwei ehemals in Deutschland ausgestorbene Arten zwischen 2000 und 2005 wieder regelmäßig gebrütet haben. Dem entgegen ist mit der Blauracke eine weitere Art ausgestorben. Schwarzstorch, Wanderfalke, Seeadler und Uhu sind hier erstmals seit der ersten deutschen Roten Liste 1971 nicht mehr aufgeführt - ein Erfolg jahrzehntelanger direkter Schutzmaßnahmen der ehrenamtlichen und amtlichen Vogelschützer und gleichzeitig ein Beweis, dass sich Vogelschutz bei stark gefährdeten Arten lohnen kann. Andererseits sind mit Schreiadler, Zwergseeschwalbe oder Großem Brachvogel Alien in die höchste Gefährdungskategorie eingestuft worden, die zwar auch im Fokus des Vogelschutzes standen und stehen, bei denen aber bislang Maßnahmen nicht ausreichend erfolgreich umgesetzt werden konnten. Gerade die Kategorie "vom Aussterben bedroht" umfasst mit nunmehr 30 Arten den höchsten Wert seit Erscheinen der gesamtdeutschen Roten Liste. Der Analyse der aktuellen deutschen Brutvogelfauna zufolge sind die Boden brütenden Vogelarten, Großinsektenfresser und Langstreckenzieher am stärksten von Gefährdungen betroffen. Vogelgruppen mit einem hohen Anteil gefährdeter Arten sind demzufolge Hühnervögel, Rallen, Limikolen und Würger, während Eulen und Schnäpperverwandte derzeit vergleichsweise wenig gefährdet sind. Zudem erfolgt deutschlandweit ein weiteres Ausdünnen der typischen Vögel in der Normallandschaft, was sich vor allem in den Trendanalysen manifestiert, aber in der Roten Liste noch nicht sehr stark zum Ausdruck kommt. Die Nutzungsintensivierungen von Land- und Forstwirtschaft in jüngster Zeit geben hier großen Anlass zur Sorge in diesen Großlebensräumen. Diese Rote Liste stellt erneut ein kritisches Zeugnis über den Zustand der deutschen Vogelwelt aus. Aufgrund der in jüngster Zeit stark ausgeweiteten Monitoringprogramme wird es in Deutschland zukünftig noch besser möglich sein, die Gefahrdung aufzuzeigen. Um den dauerhaften Rückgang der Vogelbestände zu stoppen oder wenigstens zu verlangsamen, müssen die wirksamen Gefahrdungsfaktoren reduziert und minimiert werden. Dem gezielten Vogelartenschutz stellen sich dabei folgende vordringliche Aufgaben: Erhaltung der offenen Kulturlandschaft, Erhaltung strukturreicher Walder, Erhaltung nährstoffarmer Lebensräume, Sicherung der Schutzgebiete - insbesondere Natura 2000, Stärkung der internationalen Zusammenarbeit im Vogelschutz, Reduktion der Populationsverluste durch Unfälle und menschliche Verfolgung sowie Förderung des vogelkundlichen Nachwuchses.
Glyptostrobus Endlicher is well represented in early Early Cretaceous to Pleistocene deposits in the middle to high latitudes of North America and Eurasia. Although the taxonomy and nomenclature of the genus is complicated, the fossil record indicates Glyptostrobus was represented by a small number of species. The genus first appears in Aptian age deposits from western Canada and Greenland, and achieved a wide distribution early in its evolutionary history. Exchange of Glyptostrobus between Asia and North America occurred across the Spitsbergen and Beringian corridors, which were functional about 110 and 100 million years ago, respectively The Late Cretaceous fossil record of Glyptostrobus shows that the genus had spread into Russia, China and the shores of the Turgai Strait. By the early Tertiary, Glyptostrobus was a prominent constituent of the polar broad-leaved deciduous forests. Paleocene age deposits across western Canada and the United States indicate the genus was present in great abundance in the lowland warm temperate and subtropical forests east of the Rocky Mountains. The broad distribution in North America and Russia during the Paleocene and Eocene indicates that Glyptostrobus grew and reproduced under a diverse range of climatic and environmental conditions, including the cold and unique lighting conditions of the polar latitudes. The presence of Glyptostrobus in Europe indicates the North Atlantic land bridges that extended between North America and Eurasia (Fennoscandia) and Europe during the early Tertiary were used. In Europe, extensive Glyptostrobus dominated swan1ps occupied the Central European Depression during the late Tertiary. Increasing global aridity and cooling, as well as landscape stabilization together with increasing competition for resources and habitat by representatives of the Pinaceae, seem to have forced the genus out of North America, Europe and most of Asia during the Miocene and Pliocene. In Japan, Glyptostrobus persisted until the early Pleistocene. After the early Pleistocene extinction in Japan, Glyptostrobus reappeared in southeastern China. Details of the taxonomic and biogeographic history of Glyptostrobus are examined.
The impact of naval sonar on beaked whales is of increasing concern. In recent years the presence of gas and fat embolism consistent with decompression sickness (DCS) has been reported through postmortem analyses on beaked whales that stranded in connection with naval sonar exercises. In the present study, we use basic principles of diving physiology to model nitrogen tension and bubble growth in several tissue compartments during normal div ng behavior and for several hypothetical dive profiles to assess the risk of DCS. Assuming that normal diving does not cause nitrogen tensions in excess of those shown to be safe for odontocetes, the modeling indicates that repetitive shallow dives, perhaps as a consequence of an extended avoidance reaction to sonar sound, can indeed pose a risk for DCS and that this risk should increase with the duration of the response. If the model is correct, then limiting the duration of sonar exposure to minimize the duration of any avoidance reaction therefore has the potential to reduce the risk of DCS.
The following new species are described from the Maghreb: Tapinocyba algirica n. sp. and Walckenaeria heimbergi n. sp. The unknown male of Minicia elegans and the unknown females of Alioranus pauper, Cherserigone graciipes and Entelecara truncatifrons are described. Tmeticus hipponense is transfered to the genus Gongylidiellum and HybocoptliS ericicola is removed from synonymy with H. corrugis and revalidated. The Maghrebian species of the genera Alioranus, Brachycerasphora, Cherserigone, Didectoprocnemis, Entelecara, Eperigone, Erigone, Gnathonarium, Gonatium, Gongylidiellum, Hybocoptus, Lessertia, Maso, Mierargus, Microetenonyx, Minicia, Monocephalus, Nematogmus, Ostearius, Prinerigone, Styloetetor, Tapinocyba, Triehoncoides and Trichoncus are all revised. As a final paper in a series on the Linyphiidae of the Maghreb, all the remaining genera are reviewed. A total of 169 species of Linyphiidae has currently been recorded in the Maghreb.
This review lists Agama smithii Boulenger 1896 as a synonym of Agama agama (Linnaeus 1758), Agama trachypleura Peters 1982 as a synonym of Acanthocercus phillipsii (Boulenger 1895) and describes for the first time Acanthocercus guentherpetersi n. sp. Without more convincing evidence, Chamaeleon ruspolii Boettger 1893 cannot be accepted as specifically distinct from Chamaeleo dilepis Leach 1819, nor Chamaeleo calcaricarens Böhme 1985 from C. africanus Laurenti 1768. Consequently, 101 species of lizard are currently recognised in Ethiopia, of which some 40% appear to be denizens of the Somali-arid zone. This significant proportion is attributable in part to the importance of the Horn of Africa as a centre for reptilian diversification and endemicity, in part to the fact that this lowland fauna was rather extensively sampled during the 1930s, but also to the conspicuous neglect of lizards in other regions of the country. Mountain and forested habitats are widespread in Ethiopia, so it seems extraordinary to record only five saurian species which are believed to be endemic in such environments. The inference that there are many more still to be discovered has important implications for conservation, because montane forest is known to be among the most threatened of Ethiopian biomes and there is clearly an urgent need for its herpetofauna to be more thoroughly researched and documented.
The Japanese micropterigid moths are revised. Seventeen species in five genera are recognized from Japan, described or redescribed with the male and female genital figures. Of these, two genera, Issikiomartyria HASHIMOTO and Kurolkopteryx HASHIMOTO, and seven species, Issikiomartyria akemiae HASHIMOTO, Issikiomartylia plicata HASHIMOTO, Issihiomartyria distincta HASHIMOTO, Issihiomartyria bisegmentata HASHIMOTO, Kurokopteryx dolichocerata HASHIMOTO, Neomicropteryx hiwana HASHIMOTO, and Neomicropteryx redacta HASHIMOTO, are new to science. A new combination is given: Issikiomartyria nudata (Issuu). Biology and immature structures of the Japanese species are also described together with the keys to genera and to species provided on the basis of the adult characters. Phylogenetic relationships among the Northern Hemisphere genera are analyzed by the cladistic analysis using PAUP* (SWOFFORD, 2002) based on the morphological characters of adults. A monophyly of the Northern Hemisphere genera except for Micropterix is supported by nine apomorphies, but their immediate sister taxon remains unresolved.
"Neobiota" ist ein biologischer Begriff zur Bezeichnung von nicht-einheimischen Arten, welche infolge direkter oder indirekter menschlicher Einwirkungen in neue geografische Gebiete eindringen. Biologische Invasionen durch neue gebietsfremde Lebewesen (Neobiota), die sowohl Tierarten (Neozoa) als auch Pftanzenarten (Neophyta) betreffen, wurden in den letzten Jahren zunehmend von Interesse, da ihre Anzahl und Ausbreitung ständig zunimmt. Solche Fremdlinge (Aliens) verändern oft ihre neue Umwelt, die einheimischen bodenständigen Planzen- und Tierarten müssen sich an diese ungewohnte Umgebung anpassen. Insbesondere invasive fremde Arten werden als eine der Hauptursachen für Verluste an Biodiversität erachtet. In der vorliegenden Arbeit werden für Südtirol einige markante Beispiele rezent einschleppter Tier- und Pflanzenarten erörtert. Es wird der bestehende Trend einer rezenten Zunahme von Neobiota aufgezeigt, als Folge einer Zunahme von Verkehr und Warenaustausch, und auf die Notwenigkeit hingewiesen, die Einschleppungswege und Zeiträume genau zu verfolgen und zu registrieren. Insgesamt werden hier 44 Tierarten behandelt: davon 40 Invertebraten und 4 Vertebrata, sowie 5 Pflanzenarten. Davon sind einige Arten auch Neumeldungen für Südtirol: Diptera: Rhagoletis alternata, Rhagoletis completa; Heteroptera: Leptoglossus occidentalis; Pisces: Rhodeus amarus, Pseudorasbora parva; Crustacea: Procambarus klarkii; Araneae: Atea triguttata und Araniella displicata (beides heimische Arten), Tegenaria atrica (adventiv).
Echinococcosis/hydatidosis, caused by Echinococcus granulosus, is a chronic and debilitating zoonotic larval cestode infection in humans, which is principally transmitted between dogs and domestic livestock, particularly sheep. Human hydatid disease occurs in almost all pastoral communities and rangeland areas of the underdeveloped and developed world. Control programmes against hydatidosis have been implemented in several endemic countries, states, provinces, districts or regions to reduce or eliminate cystic echinococcosis (CE) as a public health problem. This review assesses the impact of 13 of the hydatid control programmes implemented, since the first was introduced in Iceland in 1863. Five island-based control programmes (Iceland, New Zealand, Tasmania, Falklands and Cyprus) resulted, over various intervention periods (from < 15 to > 50 years), in successful control of transmission as evidenced by major reduction in incidence rates of human CE, and prevalence levels in sheep and dogs. By 2002, two countries, Iceland and New Zealand, and one island-state, Tasmania, had already declared that hydatid disease had been eliminated from their territories. Other hydatid programmes implemented in South America (Argentina, Chile, Uruguay), in Europe (mid-Wales, Sardinia) and in East Africa (northwest Kenya), showed varying degrees of success, but some were considered as having failed. Reasons for the eventual success of certain hydatid control programmes and the problems encountered in others are analysed and discussed, and recommendations for likely optimal approaches considered. The application of new control tools, including use of a hydatid vaccine, are also considered.
The first key is completed for the Palaearctic Pristiphora Latereille, 1810 species. Pristiphora araratensis sp. n. is descdbed. Pristiphora kamtchatica Malaise, 1931, Pristiphora mesatlantica Lacourt, 1976 and Pristiphora amelanchieris (Takeuchi, 1922) are new synonyms of Pristiphora insularis Rohwer, 1910.
Results from a comparative anatomical study of the mesosomal skeleton of Chalcidoidea are presented. External and internal features are described and illustrated for 39 chalcidoid taxa, representing 16 families and 29 subfamilies. This is the most comprehensive morphological study ever conducted for the superfamily. The mesosoma was dissected, macerated and investigated using scanning electron microscopy. The mesothorax and metathorax contributed most of the phylogenetically relevant information. The metafurca is highly variable within Chalcidoidea but seems to be relatively constant at the subfamily level. One hundred and fifty-four morphological characters were scored and analysed cladistically. Outgroup species were chosen from six apocritan superfamilies: Stephanoidea, Ceraphronoidea, Cynipoidea, Platygastroidea, Proctotrupoidea and Mymarommatoidea. Some previously suggested chalcidoid relationships were retrieved: (1) Pteromalidae: Pteromalinae + Miscogasterinae + Panstenoninae; (2) Perilampidae + Eucharitidae; (3) Chalcididae + Leucospidae + Eurytomidae; (4) Eulophidae: Eulophinae + Tetrastichinae + Entedoninae; and (5) Eupelmidae + Encyrtidae, Mymarommatoidea renders Chalcidoidea paraphyletic in our analyses; however, the taxon sample is too restricted to provide a robust hypothesis. Three previously unreported putative autapomorphies of Chalcidoidea were revealed: (1) presence of an exposed, triangular or diamond-shaped prosternum; (2) presence of a percurrent mesopleural sulcus anteriorly terminating in the acropleuron; and (3) presence of paired metapectal plates lateral to the metafurca.
In this paper eight tribes (Gyrophaenini, Placusini, Homalotini, Diestotini, Falagriini, Athetini, Lomechusini, and Oxypodini), 19 genera and 42 species are recognized. Four genera (Brachyglyptaglossa n. gen. [Homalotini], Trisporusa n. gen., Daccordiusa n. gen. [Lomechusini], and Antistydatusa n. gen. [Oxypodini]) and 37 species are described as new. Each new genus and species is illustrated. Placusa fauveli Pasnik, 2001, from Sydney, is placed in synonymy with Placusa tridens Fauvel, 1878, from Sydney. A new combination to Spallioda for Calodera carissima Oliff is proposed.
In dieser Arbeit werden vorwiegend taxonomische und nomenklatorische Angaben zu Cryptini und in einem Fall auch zu Phygadeuontini gemacht. Aus der Westpaläarktis sind derzeit etwa 35 Gattungen von Cryptini bekannt. Einige davon wurden in den letzten Jahrzehnten bereits revidiert (z.B. HORSTMANN 1984, 1987, 1990a, VAN ROSSEM 1966, 1969a, 1969b, 1971, SCHWARZ 1988, 1989, 1990a, 1990b, 1997). Inzwischen konnte weiteres Material untersucht werden, wodurch in einigen Fällen neue Erkenntnisse gewonnen werden konnten. In dieser Arbeit werden vor allem Ergänzungen von Revisionen westpaläarktischer Cryptini gemacht. In einigen Fällen erstrecken sich die Angaben auch auf andere Gebiete (Ostpaläarktis, Orientalis, Äthiopis), Zusätzlich werden Ergebnisse von Typenuntersuchungen angeführt. Bei den untersuchten Typen werden wahlweise die genauen Angaben auf den Etiketten wiedergegeben oder, wenn diese in anderen neueren Publikationen erwähnt sind, weggelassen. Nach den Angaben zum Typus bzw. zu den Funddaten bei zusätzlichem Material wird jeweils der Aufbewahrungsort angegeben. Die Reihung der hier behandelten Gattungen und Arten erfolgt alphabetisch. Bei der Auflistung des untersuchten Materials werden entweder die genauen Funddaten, besonders bei Material außerhalb von Europa, oder nur die Länder aufgelistet. Inseln werden, da tiergeografisch besonders interessant, gesondert angeführt.
Taxonomic diversity of European Cottus : with description of eight new species (Teleostei: Cottidae)
(2005)
The taxonomy of European species of Coitus (Cottidae) is revised. Results of molecular studies are summarised and the variability of morphological characters is reviewed. Molecular and morphological data support the recognition of 15 diagnosable species in Europe. A neotype is designated for C. gobio; the type locality is in the lower Elbe drainage. Coitus gobio, C. hispaniolensis, C. koshewnikowi, C. microstomus, C. petiti, and C. poecilopus are re-diagnosed. Eight new species are described. Three of them are restricted to France: C. aturi to the Adam drainage, C. duranii to the upper Dordogne, upper Lot and upper Loire drainages, and C. rondeleti to the Herault drainage. Two new species are described from the Atlantic and North Sea basins: C. perifretum from Great Britain, and the ScheIdt, Rhine, Seine, lower Loire and lower Garonne drainages, and C. rhenanus from the Meuse and lower and middle Rhine drainages. Coitus scatul'igo is described from a single spring in northeastern Italy. In the Danube drainage, C. mctae front the upper Save and C. transsilvaniae from the upper Arges are distinguished from the widespread C. gobio. Lectotypes are designated for C. ferrugineus and C. pellegrini. Coitus kosllewnikowi Gratzianow, 1907 is declared nomel1 protectum and C. gobio microcephalus Kessler, 1868 is declared nomen oblitum. The original spelling of C. milvensis is discussed.
A synthesis of the Carabid fauna of the Central and Eastern Alps and Pre-Alps, from a biogeographical point of view, is presented. Only the Italian side of the Alpine chain is considered, from the basin of the Toce river to the Trieste and Gorizia Karst. Main features of the landscape are: 1. an ancient orogenetic history and evolution, that made this area available to the colonization by carabids, of both gondwanaland and laurasian lineages, since the lower Tertiary; 2. a marked geological and geo-morphological complexity, with highest elevation at Pizzo Bernina m 4.049; 3. the presence of a very developed, dolomitic-calcareous and markedly carsified prealpine belt, rich of deep and large hypogean systems (also at high altitude), which makes this area highly different, from the geo-morphological point of view, from the Western Alps; 4. the geographic position, as a mountain chain of some 750 kms between central Europe and the Padanian plain, connected with the Caravanche and the Dinaric chain and close to the Adriatic sea in me Eastern part; 5. finally, a puzzled climate situation, that includes xero-thermic areas (500-700 mm of rain per year, also in some intra-alpine sectors), close to highly rainy areas - more than 2.500 mm per year - in the westernmost and easternmost parts of the chain. Thus, like in the Western Alps, sub-mediterranean vegetation types, dose to cool-moist forests, coexist with high-altitude environments above the timber line. These facts explain the heterogeneity, the richness, the variety, and the interest of the carabid fauna of the area: the highest number of species (658) ascertained so far, i.e. 112 of the whole Italian carabid fauna and about 115 of the carabid fauna cited so far for the Europe in politic sense, fi·om me Canary islands to the Urals; the high number of euri- or stenoendemites (204, i.e. abour 31 % of the species, 3/5 of which concentrated in the pre-alpine belt), and the complex origins and/or affinities of different taxa. A large number of species (174, i.e. 26%) belongs to European chorotypes (European, South-European or typically Alpine), and even more (255, i.e. 38%) to Holarctic (Holarctic, Palaearccic, West-Palaearctic, Asiatic-European, Siberian-European, Central-Asiatic-European, Central-Asiatic-European-Mediterrancan, Turanic-European, Turanic-EuropeanMediterranean, European-Mediterranean) chorotypes. This darum confirms the well known role, both of connection and separation, that the Alps as a whole played between Europe and the Mediterranean area. Furthermore, it is to be recalled the presence, in some localities of the Eastern Alps, of micro thermophilous, boreal species, like Miscodera arctica, now widespread in Northern regions of the Holarctic Region. Many orophilous, forest-dwelling, riparian and hygrophilolls species, are of northern, north-eastern, ruranic or dinaric-balkanian origin. A very small, bur interesting group of thermophilous elements (mostly Harpalini), originally from the Mediterranean area or temperate steppes, during the hypsothermic periods of the Pleistocene and Olocene, reached the Central and Eastern Alps and Pre-Alps, and persist in xerothermlc biotopes. Some of these could increase their range of distribution as a consequence human activities in agricultural use overgrazing and deforestation. Some others, like Carabus montivagus and Laemostenus algerinus, seem to be present owing to very recent anthropogenic introduction. From the biogeograpic point of view, however the most important group of species is represented by the impressive number of endemics (204, of which 116 species restricted to politic Italy), either eurendemics to Central and Eastern Alps and Pre-Alps, or stenoendemics to single sectors of the area or to very small biotopes (caves, isolated montane massifs): among these, we may cite some large-sized species like Cychrus cylindricollis, endemic at high altitude, to the Central Pre-Alps, several montane, very localized Trechus species, many subterranean, highly specialized Trechini of the peculiar genera Boldoriella, Orotrechus, Anophthalmus, Allegrettia, Italaphaenops, Lessinodytes: many Pterostlchini, and others, Most of them must be considered as pre-Quaternarian elements, With affinltl,es either til Gondwana (such as the blind Reicheina of the genus Alpiodytes), or in the Angarian (as the Broscosoma species) areas, They are, the result of an ancient, subtropical or temperate forest dweller Carabid fauna, tied now to soil: forest littter, superficlal subterranean environment, caves, and upper montane refugia, Both from floristic and faunistic informatlon, It IS a well known fact that the pre-alpine belt as a whole represents a large, unique Pleistocene refugium, that shows a scenario of marked isolation and speciation in mountains, valleys and hypogean compartments. The analysis of the entire Carabid fauna in the Central and Eastern Alps and Pre-Alps shows that the present composition and complexity is the result both of ancient clado-vicariance events and of recellt, ecological factors, These facts surprisingly make this area (not only concerning carabids) very close to important towns and to one of the most populated, cultivated and industrialized area of Italy (the Padanian plain), and in spite of its relatively small surface, one of the most important hot spar of biodiversity in Europe, in which many biotopes are presently highly endangered, or in some cases completely destroyed, A checklist of the Carabid species of the Central and Eastern Alps and Pre-Alps, with their chororypes, is added.
A world revision of the four entedonine (Hymenoptera: Eulophidae: Entedoninae) genera of larval parasitoids of thrips (Thysanoptera) is presented: Ceranisus Walker, 1841, Entedonomphale Girault, 1915 stat. rev. (reinstated as a valid taxon from previous synonymy under Ceranisus, with type species E. margiscutum Girault, 1915 stat. rev.), Goetheana Girault, 1920, and Thripobius Ferrière, 1938. The following new generic synonymies are proposed: Cryptomphale Girault, 1917, Entedonastichus Girault, 1920, Pirenoidea Girault, 1922, and Thripoctenoides Erdös, 1954 under Entedonomphale. The proposed new combinations are as follows: Entedonomphale bicolorata (Ishii, 1933), E. nubilipennis (Williams, 1916), and Thripobius javae (Girault, 1917) from Ceranisus; Entedonomphale carbonaria (Erdös, 1954), E. dei (Girault, 1922), E. kaulbarsi (Yoshimoto, 1981), and E. mira (Girault, 1920) from Entedonastichus. New synonymies are proposed for the following species: Ceranisus vinctus (Gahan, 1932) under Ceranisus menes (Walker, 1839), Diglyphus aculeo Walker, 1848 under Ceranisus pacuvius (Walker, 1838); Ceranisus maculatus (Waterston, 1930) and Thripobius semiluteus Boucek, 1976 under Thripobius javae (Girault, 1917); Entedonastichus albicoxis (Szelényi, 1982) under Entedonomphale carbonaria (Erdös, 1954), and Entedonastichus gaussi (Ferrière, 1958) under Entedonomphale bicolorata (Ishii, 1933). Eleven new species are described: Ceranisus barsoomensis and C. votetoda (Australia), C. udnamtak (Nepal); Entedonomphale boccaccioi (USA), E. esenini (Madagascar), E. lermontovi (South Africa), E. quasimodo and E. zakavyka (Australia); Goetheana pushkini (Japan and Republic of Korea) and G. rabelaisi (Australia); and Thripobius melikai (China). Three species are excluded from Ceranisus: C. ancylae (Girault, 1917) (mistakenly listed in Ceranisus) as well as C. nigricornis Motschulsky, 1863 and C. semitestaceus Motschulsky, 1863, both taxa incertae sedis. New data are provided on the distribution and host associations of many of the species included in this review.
South-Western Anatolia (including provinces Antalya, Burdur, Isparta, Denizli, Aydın, Muğla) was surveyed for the fauna of Neuroptera during 2000–2002. In total, 2817 specimens representing 77 species, 43 genera and 10 families: Osmylidae (1 species), Chrysopidae (22 species), Hemerobiidae (11 species), Coniopterygidae (7 species), Dilaridae (1 species), Mantispidae (4 species), Berothidae (1 species), Nemopteridae (3 species), Myrmeleontidae (22 species), Ascalaphidae (6 species). The records of Nineta guadarramensis, Sympherobius (S.) elegans, Nimboa ressli, Dilar turcicus, Mantispa aphavexelte, Synclisis baetica, Solter ledereri, Myrmeleon inconspicuous, Megistopus flavicornis are their second records from Turkey. Fourty five species are recorded for the first time from the studied area. As a result of the present study the total number of species reported from Southwest Anatolia increased to 87.
A taxonomic revision of the genus Syntrichia Brid. (Pottiaceae, Musci) in the Mediterranean Region and Macaronesia has been carried out, thus contributing to knowledge of its distinguisliing morphological characters, geographic distribution and nomenclature. Some 3000 specimens, including the most of type material, were studied. An identification key, morphological descriptions, photographs and numerous observations on taxonomic and nomenclatural problems of the 23 taxa accepted in the study area, are provided. New records for some countries of the Mediterranean basin and Macaronesia are given. Five new Synonyms are proposed. The designations of 11 new lectotypes are included and the name Syntrichia aciphylla var. calva J.J. Amann is excluded from the genus Syntrichia.
During the last decade, three new acidophilous forests associations were detected in the Mecsek Mts (SW Hungary), and described as acidophilous beech wood (Sorbo torminalis-Fagetum (A. O. Horvat 1963a) Borhidi et Kevey in Kevey 2001), acido-mesophilous oak wood (Luzulo forsteri-Quercetum petraeae (A. O. Horvat 1963a) Borhidi et Kevey 1996) and acido-xerophilous oak shrubland (Genisto pilosae-Quercetum polycarpae (A. O. Horvat 1967) Borhidi et Kevey 1996). In this article two further new associations are described: the acidophilous oakwood of the Mecsek (Viscario-Quercetum polycarpae Kevey, ass. nova) and the acido-mesophilous oakwood of western Hungary (Campanulo rotundifoliae-Quercetum petraeae (Csapody 1964) Kevey, ass. nova). These associations are related to the acidophilous forests of the Balkan Peninsula based on the infrequent presence of sub-Mediterranean species. A detailed comparative study of these new associations with the earlier known ones permitted to develop a reshaped classification of the syntaxonomy of these units, creating four new suballiances: within the frame of Quercion farnetto I. Horvat 1938 the suballiances Luzulo forsteri-Quercenion polycarpae Kevey, suball. nova and the typical Quercenion farnetto Kevey, suball. nova, in the frame of Quercion petraeae Zolyomi et Jakucs 1957 the suballiances Luzulo multiflorae-Quercenion petraeae Kevey, suball. nova and the Quercenion petraeae Kevey, suball. nova.
A taxonomic review of the species belonging to Bembidion Latreille, 1802 of Australia includes a key and descriptions of the species. Noinenclatorial acts proposed in this paper include: 1, taxa of new Status - Bembidion subgenus Sloanephila Netolitzky, 1931, valid subgenus, not consubgeneric with subgenus Philochtus Stephens, 1828; B. (Notaphocampa) riverinae Sloane, 1894 valid species, not subspecies of B. opulentum Nietner, 1858; 2, new synonyms B. (Notaphominis Netolitzky, 1931) = B. (Notaphocampa Netolitzky, 1914): 3, New subgenera - Australoemphanes, and Gondwanabembidion, 4, New species - B. (Ananotaphus) daccordii (South Australia, Mound Springs); 5, new subspecies - B. (Zeactedium) orbiferum giachinoi (New ZeaIand, North Island); 6, species transferred to Australoemphanes - B . (Ananotaphus) blackburni Csiki, 1928; 7, Species transferred to Gondwanabembidion - B . (Ananotaphus) proprium Blackburn, 1888. Conclusions of an informal phylogeographic study are: 1, the Auslralian continent was probably populated by the Bembidiina with relatively recent (Late Tertiary-Quaternary) invasions from the north by tropical lineages, while other lineages showing systematic relationships with African and South American taxa probably have an older, Gondwanian origin; and 2, some lineagas of predominantly Nearctic and Palaearctic taxa were also Gondwanian in origin.
Sensilla styloconica are elongated microscopically conspicuous chemo-mechano receptors found exclusively at the tongue tip of many adult Lepidoptera. These unique proboscis sensilla were comparatively studied using the scanning electron microscope in 107 species of North American and tropical butterflies. Focus was on 76 species of North American Nymphalidae representing 45 genera and 11 subfamily groups, and 15 species of tropical Nymphalidae representing additional genera and subfamilies. Observations of adult nymphalid feeding behaviour and food preference for correlation with morphological characteristics were made largely in North America and substantially in the Neotropics, where bait traps were used in conjunction with aerial netting. The tongue tips of 16 additional species representing 5 more butterfly families were also examined for the presence and morphological characteristics of sensilla styloconica.
Catalog of the mosses of Japan compiled by the author in 1991 was revised. This new catalog lists all names of genera and species of mosses described or reported from Japan, based on all literature available to the author up to the end of January 2004. The new catalog is comprised of 1,135 species of mosses belonging to 332 genera. These taxa are listed in alphabetical order. Each valid epithet is followed by author citation, literature, distributional area in Japan, and Japanese name.
A taxonomic study of the Staphylinid subfamily Aleocharinae of the Australian Region is presented, including a critical revision of 14 typical series, the lectotype of which is designated when necessary. 10 new genera are deseribed (3 in Athetini, 2 in Thamiaraeini, and 5 in Oxypodini) and 38 species (3 in Gyrophaenini, 2 in Bolitocharini, 4 in Diestotini, 21 in Athetini, 5 in Thamiaraeini, and 3 in Oxypodini). New combinations are proposed for 12 species (l in Homalotini, 1 in Diestotini, 3 in Athetini, 6 in Oxypodini, and 1 in Aleocharini). The genus Correa Fauvel is considered junior synonym of the genus Aleochara. Every new genus and species is described and illustrated.
This is the most comprehensive analysis of higher-level relationships in Odonata conducted thus far. The analysis was based on a detailed study of the skeletal morphology and wing venation of adults, complemented with a few larval characters, resulting in 122 phylogenetically informative characters. Eighty-five genera from forty-five currently recognized families and subfamilies were examined. In most cases, several species were chosen to serve as exemplars for a given genus. The seven fossil outgroup taxa included were exemplar genera from five successively more distant odonatoid orders and suborders: Tarsophlebiidae (the closest sister group of Odonata, previously placed as a family within "Anisozygoptera"), Archizygoptera, Protanisoptera, Protodonata and Geroptera. Parsimony analysis of the data, in which characters were treated both under equal weights and implied weighting, produced cladograms that were highly congruent, and in spite of considerable homoplasy in the odonate data, many groupings in the most parsimonious cladograms were well supported in all analyses, as indicated by Bremer support. The analyses supported the monophyly of both Anisoptera and Zygoptera, contrary to the well known hypothesis of zygopteran paraphyly. Within Zygoptera, two large sister clades were indicated, one comprised of the classical (Selysian) Calopterygoidea, except that Amphipterygidae, which have traditionally been placed as a calopterygoid family, nested within the other large zygopteran clade comprised of Fraser´s "Lestinoidea" plus "Coenagrionoidea" (both of which were shown to be paraphyletic as currently defined). Philoganga alone appeared as the sister group to the rest of the Zygoptera in unweighted cladograms, whereas Philoganga + Diphlebia comprised the sister group to the remaining Zygoptera in all weighted cladograms. "Anisozygoptera" was confirmed as a paraphyletic assemblage that forms a "grade" towards the true Anisoptera, with Epiophlebia as the most basal taxon. Within Anisoptera, Petaluridae appeared as the sister group to other dragonflies.
Die allgemein angewandten Namen der europäischen Orchideentaxa belaufen sich derzeit auf über 580 Namen, Synonyme nicht eingeschlossen. Die Übersicht soll die Namensfülle der gebräuchlichen Taxa und ihrer Synonyme (soweit erforderlich) in alphabetischer Reihenfolge aufzeigen. Taxa auf der Rangstufe der Varietät sind nicht enthalten.
On the occurence of bats (Chiroptera) in South Tyrol (2): Vespertilionidae Since 1988 the author has been collecting and recording bat observations in South Tyrol. From 1990 to 1991 and from 1995 to 1997, in two different studies, he carried on a survey on the presence, the frequency and the horizontal and vertical dispersal of the various species of bats. The first task was on one hand to search the attics and steeples of about 700 churches and chapels; and, on the other hand, to answer the numerous calls telling of the presence of bats in private houses, to capture bats for a check-up and to inform people about European bats beeing harmless for humans, animals and houses. There is good evidence of 23 species of bats in South Tyrol since 1988 and of the reproduction of 18 of them, as well as there are single discoveries of three further species, and finally summer colonies of two species. As there is no certified evidence of the presence of Pipistrellus pygmaeus and of Plecotus alpinus they have not been included in this record. The data-base already provides a good idea of the presence and frequency of bat-species. Species which are frequent in Central Europe have been found almost everywhere in South Tyrol (e.g. Pipistrellus pipistrellus, Plecotus sp.), some of them in several colonies with a considerable number of individuals. The Etsch/ Adige Valley as far up as Meran/Merano - due to its mild climate - makes home for a few Mediterrean species. The few possibilities we got from scientific pubblications to make a comparison with former times let suppose that the bat occurences have diminued only in a few species. The reasons are to search mainly in the diminued offer of food.
The Great Spotted Woodpecker is the most common and best-known woodpecker species in the W Palearctic. The sections Habitat, Distribution, Population, Movements, Food, Social pattern and behaviour, Voice, Breeding, Plumages, Bare parts, Moults, Measurements, Weights, and Geographical variation have been updated or completely rewritten, and a new section has been added on Conservation. High flexibility enables the Great Spotted Woodpecker to utilize a great variety of habitats, from Arctic taiga through boreal and temperate to Mediterranean (N Africa and Canary Islands) and Alpine forest zones, wherever there are mature trees of any sort with sufficient growth to accommodate nest-holes and with a supply of available food. The Distribution and Population sections include new data of population tendencies, with stable or positive trends in most European countries and fluctuating populations in N Europe. Recent negative range trends with small decreases only in S Europe, apparently due to loss of wooded habitats. The Conservation section presents literature on the Great Spotted Woodpecker as the key or umbrella species for secondary cavity-nesting species. This section also demonstrates the importance of woodpeckers as indicators for naturally dynamic forests with tree species diversity, forest management, and sustainable forestry. Woodpeckers can be part of a monitoring system of e.g. sustainable forestry, but species from other organism groups are also required. The section on Movements has been updated with new data on dispersal and summer/autumn and spring migration. The Great Spotted Woodpecker uses a very wide and varied diet and is characterized as a 'universalist' in food-gathering; pecking and hammering are most important in autumn and winter, gleaning and probing are important at times of high food availability at the tree surface in spring and summer. It takes arthropods and insect larvae, coniferous seeds and various nuts mainly in autumn and winter, and drills holes for sap-sucking in spring, takes surface dwelling arthropods and caterpillars, bird eggs and nestlings, and fruits and berries in spring and summer. The Social pattern and behaviour section presents new data on the mating system, parental effort, pair-bond, divorce rate, survival rate, and mortality. Great Spotted Woodpeckers are socially and genetically monogamous with a potential to polyandry, which was recorded in Japan. Changes of partner between seasons common. Males usually invest more in nesthole construction and guarding than the females and contribute the same amount or more to brood care. Males usually incubate and brood at night, as with all studied woodpeckers, and defend territories, which seem to be important for female choice. Females compete intensely for access to males and perform male-like courtship behaviours such as drumming. Great Spotted Woodpeckers are intelligent and currently doing damage to house facades. The Voice section presents mainly new data on calls and instrumental signals of the young. The Breeding section has been updated with new information about nest-sites, breeding behaviour, and breeding success. New data on age determination are shown in the Bare parts and Moults sections. Additional data are provided on size and weight.
A cladistic analysis is presented of the hawkmoths of the tribe Acherontiini, Morgan´s Sphinx (Xanthopan morganii (Walker», and related genera. The study aims to test the monophyly of tribe Acherontiini; the hypothesis that all taxa with extremely long probosces (some Acherontiini, Meganoton rubescens, Neococytius, Xanthopan) form a monophyletic group, or at least fall within a single reasonably compact clade; and, within this group, to determine whether Xanthopan is more closely related to Acherontiini or to COCytillS and Neococytius. The data set comprises 109 characters derived from adult and immature stage morphology, biology and behaviour. These data were analysed using equal weighting, successive approximations character weighting (SACW) and implied weighting. All weighting schemes agreed on the monophyly of Acherontiini and of a group of genera comprising Amphimoea, Cocytius and Neococytius (the Cocytius group). Several other generic and suprageneric clades were also consistently recovered. However, those hawkmoths with extremely long probosces were never recovered as a monophyletic group. The relationships of Xanthopan were also ambiguous. Equal weighting and SACW placedXanthopan + Meganoton rztbescens (Butler) as sister to the COCytills group, while implied weighting placed Xanthopan as sister to Acherontiini. This latter relationship is based primarily on shared possession of a pilifer/palp hearing organ. Further analyses suggested the two components of this organ were not biologically independent. Downweighting this feature accordingly resulted in all weighting schemes converging on the topology found by equal weighting. Exclusion of the incomplete subset of immature stage data had no effect under implied weighting but equal weighting and SACW now recovered a Neotropical clade comprising Manduca. and the Cocytius group, while Xanthopan was placed with M. rubescens and Panogena. Downweighting the pilifer/palp hearing organ under implied weighting again caused convergence with the equal weighting/SACW results. Thus, the relationships of Xanthopan remain equivocal and further data, particularly from the immature stages, will be required to elucidate its phylogenetic position further.
The Siwalik formations of northern Pakistan consist of deposits of ancient rivers that existed throughout the early Miocene through the late Pliocene. The formations are highly fossiliferous with a diverse array of terrestrial and freshwater vertebrates, which in combination with exceptional lateral exposure and good chronostratigraphic control allows a more detailed and temporally resolved study of the sediments and faunas than is typical in terrestrial deposits. Consequently the Siwaliks provide an opportunity to document temporal differences in species richness, turnover, and ecological structure in a terrestrial setting, and to investigate how such differences are related to changes in the fluvial system, vegetation, and climate. Here we focus on the interval between 10.7 and 5.7 Ma, a time of significant local tectonic and global climatic change. It is also the interval with the best temporal calibration of Siwalik faunas and most comprehensive data on species occurrences. A methodological focus of this paper is on controlling sampling biases that confound biological and ecological signals. Such biases include uneven sampling through time, differential preservation of larger animals and more durable skeletal elements, errors in age-dating imposed by uncertainties in correlation and paleomagnetic timescale calibrations, and uneven taxonomic treatment across groups. We attempt to control for them primarily by using a relative-abundance model to estimate limits for the first and last appearances from the occurrence data. This model also incorporates uncertainties in age estimates. Because of sampling limitations inherent in the terrestrial fossil record, our 100-Kyr temporal resolution may approach the finest possible level of resolution for studies of vertebrate faunal changes over periods of millions of years. Approximately 40,000 specimens from surface and screenwash collections made at 555 localities form the basis of our study. Sixty percent of the localities have maximum and minimum age estimates differing by 100 Kyr or less, 82% by 200 Kyr or less. The fossils represent 115 mammalian species or lineages of ten orders: Insectivora, Scandentia, Primates, Tubulidentata, Proboscidea, Pholidota, Lagomorpha, Perissodactyla, Artiodactyla, and Rodentia. Important taxa omitted from this study include Carnivora, Elephantoidea, and Rhinocerotidae. Because different collecting methods were used for large and small species, they are treated separately in analyses. Small species include insectivores, tree shrews, rodents, lagomorphs, and small primates. They generally weigh less than 5 kg. The sediments of the study interval were deposited by coexisting fluvial systems, with the larger emergent Nagri system being displaced between 10.1 and 9.0 Ma by an interfan Dhok Pathan system. In comparison to Nagri floodplains, Dhok Pathan floodplains were less well drained, with smaller rivers having more seasonally variable flow and more frequent avulsions. Paleosol sequences indicate reorganization of topography and drainage accompanying a transition to a more seasonal climate. A few paleosols may have formed under waterlogged, grassy woodlands, but most formed under drier conditions and more closed vegetation. The oxygen isotopic record also indicates significant change in the patterns of precipitation beginning at 9.2 Ma, in what may have been a shift to a drier and more seasonal climate. The carbon isotope record demonstrates that after 8.1 Ma significant amounts of C4 grasses began to appear and that by 6.8 Ma floodplain habitats included extensive C4 grasslands. Plant communities with predominantly C3 plants were greatly diminished after 7.0 Ma, and those with predominantly C4 plants, which would have been open woodlands or grassy woodlands, appeared as early as 7.4 Ma. Inferred first and last appearances show a constant, low level of faunal turnover throughout the interval 10.7–5.7-Ma, with three short periods of elevated turnover at 10.3, 7.8, and 7.3–7.0 Ma. The three pulses account for nearly 44% of all turnover. Throughout the late Miocene, species richness declined steadily, and diversity and richness indices together with data on body size imply that community ecological structure changed abruptly just after 10 Ma, and then again at 7.8 Ma. Between 10 and 7.8 Ma the large-mammal assemblages were strongly dominated by equids, with more balanced faunas before and after. The pattern of appearance and disappearance is selective with respect to inferred habits of the animals. Species appearing after 9.0 Ma are grazers or typical of more open habitats, whereas many species that disappear can be linked to more closed vegetation. We presume exceptions to this pattern were animals of the mixed C3/C4 communities or the wetter parts of the floodplain that did not persist into the latest Miocene. The pace of extinction accelerates once there is C4 vegetation on the floodplain. The 10.3 Ma event primarily comprises disappearance of taxa that were both common and of long duration. The event does not correlate to any obvious local environmental or climatic event, and the pattern of species disappearance and appearance suggests that biotic interactions may have been more important than environmental change. The 7.8 Ma event is characterized solely by appearances, and that at 7.3 Ma by a combination of appearances and disappearances. These two latest Miocene events include more taxa that were shorter ranging and less common, a difference of mode that developed between approximately 9.0 and 8.5 Ma when many short-ranging and rare species began to make appearances. Both events also show a close temporal correlation to changes in floodplain deposition and vegetation. The 7.8 Ma event follows the widespread appearance of C4 vegetation and is coincident with the shift from equid-dominated to more evenly balanced large-mammal assemblages. The 7.3 to 7.0 Ma event starts with the first occurrence of C4-dominated floras and ends with the last occurrence of C3-dominated vegetation. Absence of a consistent relationship between depositional facies and the composition of faunal assemblages leads us to reject fluvial system dynamics as a major cause of faunal change. The close correlation of latest Miocene species turnover and ecological change to expansion of C4 plants on the floodplain, in association with oxygen isotopic and sedimentological evidence for increasingly drier and more seasonal climates, causes us to favor explanations based on climatic change for both latest Miocene pulses. The Siwalik record supports neither “coordinated stasis” nor “turnover pulse” evolutionary models. The brief, irregularly spaced pulses of high turnover are characteristic of both the stasis and pulse models, but the high level of background turnover that eliminates 65–70% of the initial species shows there is no stasis in the Siwalik record. In addition, the steadily declining species richness and abrupt, uncoordinated changes in diversity do not fit either model.
