This book was released on 1990 with total page 214 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The subfamily Phyxelidinae Lehtinen of the Amaurobiidae is diagnosed and revised, and a key to and distribution maps of the 53 valid and 1 undescribed species are provided. The subfamily comprises 12 genera placed in three newly described tribes: Ambohima, new genus, Kulalania new genus, Lamaika, new genus, Malaika Lehtinen, Matundua Lehtinen, Namaquarachne, new genus, Phyxelida Simon, Pongolania, new genus, Themacrys Simon, Vidole Lehtinen, Vytfutia Deeleman-Reinhold, and Xevioso Lehtinen. Vytfutia is newly transferred to the Phyxelidinae. Members of the Phyxelidinae occur in Africa, Madagascar, the eastern Mediterranean, and southeast Asia. The Phyxelidinae is monophyletic and is defined by the following putative synapomorphies: at least some of the basal prolateral setae on the palpal femora of both sexes are enlarged, and in many species the setae are also modified into thorns; the tarsal trichobothria are lost and the metatarsal pattern is reduced to a single subapical dorsal trichobothrium; and the origin of the calamistrum is shifted to the median part of the fourth metatarsus. Previous familial placements of the spiders here placed in the Phyxelidinae are critically evaluated, and it is concluded that the Phyxelidinae are members of the Amaurobiidae. The Amaurobiidae is redefined on the basis of putative synapomorphies as spiders with a divided cribellum which have simple, sclerotized retrolateral and dorsal tibial processes on the male palp (however, the retrolateral process is lost in all Phyxelidinae except Vytfutia). A cladogram for the 54 species of the Phyxelidinae derived through numerical parsimony analysis using Swofford's program PAUP is presented. The following new taxa are proposed: new tribes: Vytfutiini, Vidoleini, and Phyxelidini; new genera: Ambohima (type species Ambohima sublima, new species, from Madagascar), Kulalania (type species Kulalania antiqua, new species, from Kenya), Lamaika (type species Lamaika distincta, new species, from South Africa), Namaquarachne (type species Namaquarachne khoikhoiana, new species, from South Africa), and Pongolania (type species Pongolania pongola, new species, from South Africa); new species: Ambohima sublima and A. pauliani; Kulalania antiqua; Lamaika distincta; Malaika delicatula; Namaquarachne angulata, N. khoikhoiana, N. thaumatula, and N. tropata; Phyxelida abyssinica, P. anatolica, P. apwania, P. carcharata, P. crassibursa, P. eurygyna, P. fanivelona, P. irwini, P. jabalina, P. kipia, P. malagasyana P. pingoana, P. sindanoa, and P. umlima; Pongolania chrysionaria and P. pongola; Themacrys ukhahlamba; Vidole V. helicigyna, V. lyra, and V. sothoana; Xevioso amica, X. aululata, X. colobata, X. jocquei, X. kulufa, X. lichmadina, and X. orthomeles. The following new synonymies are proposed: Haemilla grindleyi Lawrence with Malaika longipes (Purcell); Haemilla profundissima Lawrence with Vidole capensis (Pocock). The synonymies of Auximus schreineri Purcell with Auximus capensis Pocock, and of Haemilla tanganensis Simon and Fage with Amphigyrum nebulosum Tullgren, are rejected. Themacrys stolida Simon is considered a nomen dubium"--Page 3

This book was released on 2002 with total page 156 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Holarctic coelotine spiders are revised at the generic level. Coelotine morphology, particularly genitalic morphology, is described, the subfamily and generic limits are defined, and a cladistic hypothesis of generic relationships is presented. The subfamily Coelotinae is defined to include 20 genera and 277 species. The 20 genera are: Ambanus Ovtchinnikov, 1999, with 18 species from far eastern Russia, northeastern China, Japan, and Korea (including 6 new combinations); Asiacoelotes, new genus, with 15 East Asian species (all new combinations, with 3 new synonyms); Bifidocoelotes, new genus, with 2 species from China (both new combinations); Coelotes Blackwall, 1841, with 123 species from Europe and Asia (including 2 new synonyms); Coras Simon, 1898, with 15 North American species and 2 species from China; Coronilla Wang, 1994, with 2 species from China (including 2 new synonyms); Draconarius Ovtchinnikov, 1999, with 26 Asian species (including 25 new combinations and 1 new synonym); Eurocoelotes, new genus, with 11 European species (all new combinations); Femoracoelotes, new genus, with 2 species from Taiwan (both new combinations); Himalcoelotes, new genus, fully revised here, with 10 species from the Himalayas (including 2 new combinations and 8 new species); Leptocoelotes, new genus, with 2 species from China (both new combinations); Longicoelotes, new genus, with 1 new species from China; Paracoelotes Brignoli, 1982, with 16 European and Asian species (including 5 new combinations and 5 new synonyms); Platocoelotes, new genus, with 4 species from China (all new combinations); Robusticoelotes, new genus, with 1 newly combined species from China; Spiricoelotes, new genus, with 2 East Asian species (both new combinations); Tegecoelotes Ovtchinnikov, 1999, with 5 species from far eastern Russia, northeastern China, Japan, and Korea (including 4 new combinations); Tonsilla Wang and Yin, 1992, with 3 species from China; Urocoras Ovtchinnikov, 1999, with 5 species from East Europe (including 2 new combinations); and Wadotes Chamberlin, 1925, with 11 species from North America and 1 from China.

Book excerpt: One of the only books to treat the whole spider, from its behavior and physiology to its neurobiology and reproductive characteristics, Biology of Spiders is considered a classic in spider literature. First published in German in 1979, the book is now in its third edition, and has established itself as the supreme authority on these fascinating creatures. Containing five hundred new references, this book incorporates the latest research while dispelling many oft-heard myths and misconceptions that surround spiders. Of special interest are chapters on the structure and function of spider webs and silk, as well as those on spider venom. A new subchapter on tarantulas will appeal especially to tarantula keepers and breeders. The highly accessible text is supplemented by exceptional, high-quality photographs, many of them originals, and detailed diagrams. It will be of interest to arachnologists, entomologists, and zoologists, as well as to academics, students of biology, and the general reader curious about spiders.

Book excerpt: Compared to insects, fossil spiders have received only scant attention in the literature. Previously, the only works available were numerous scientific papers, many published in foreign languages. Most of these are basic descriptive taxonomic works, with very few considering broader biological concepts. Despite a significant increase in the discovery and description of fossil spiders within the last quarter Century this void remained unfilled. Thus, this short monograph aims to achieve several objectives. Firstly, to provide general and up to date background information on the overall importance and diversity of fossils spiders, including an indication of those groups for which the taxonomy is spurious and in need of reassessment. Secondly, to discuss the techniques available for working with fossil spiders and some of the problems encountered by palaeoarachnologists, including bias and limitations of the spider fossil record. Thirdly, the overall evolutionary history of spiders is summarized in the form of an evolutionary tree, which is subsequently used to address key issues of broad interest, such as origins, diversifications and extinctions, including the effects of mass extinctions and predator-prey co-radiations. Finally, the contribution that fossil data can make to understanding the past and present biogeography of the order is considered. This book should be of interest to both amateur and professional arachnologists and palaeontologists and will also serve as a general palaeontological reference work for neonologists studying extant spiders.

This book was released on 2010-07-16 with total page 550 pages. Available in PDF, EPUB and Kindle. Book excerpt: Primary sexual traits, those structures and processes directly involved in reproduction, are some of the most diverse, specialized, and bizarre in the animal kingdom. Moreover, reproductive traits are often species-specific, suggesting that they evolved very rapidly. This diversity, long the province of taxonomists, has recently attracted broader interest from evolutionary biologists, especially those interested in sexual selection and the evolution of reproductive strategies. Primary sexual characters were long assumed to be the product of natural selection, exclusively. A recent alternative suggests that sexual selection explains much of the diversity of "primary" sexual characters. A third approach to the evolution of reproductive interactions after copulation or insemination has been to consider the process one of sexual conflict. That is, the reproductive processes of a species may reflect, as does the mating system, evolution acting on males and on females, but in different directions. In this volume, authors explore a wide variety of primary sexual characters and selective pressures that have shaped them, from natural selection for offspring survival to species-isolating mechanisms, sperm competition, cryptic female choice and sexual arms races. Exploring diverse reproductive adaptations from a theoretical and practical perspective, The Evolution of Primary Sexual Characters will provide an unparalleled overview of sexual diversity in many taxa and an introduction to the issues in sexual selection that are changing our view of sexual processes.

Book excerpt: Anyone wishing to tap the research potential of the hundreds of Drosophila species in addition to D.melanogaster will finally have a single comprehensive resource for identifying, rearing and using this diverse group of insects. This is the only group of higher eukaryotes for which the genomes of 12 species have been sequenced.The fruitfly Drosophila melanogaster continues to be one of the greatest sources of information regarding the principles of heredity that apply to all animals, including humans. In reality, however, over a thousand different species of Drosophila exist, each with the potential to make their own unique contributions to the rapidly changing fields of genetics and evolution. This book, by providing basic information on how to identify and breed these other fruitflies, will allow investigators to take advantage, on a large scale, of the valuable qualities of these other Drosophila species and their newly developed genomic resources to address critical scientific questions.* Provides easy to use keys and illustrations to identify different Drosophila species* A guide to the life history differences of hundreds of species* Worldwide distribution maps of hundreds of species* Complete recipes for different Drosophila diets* Offers an analysis on how to account for species differences in designing and conducting experiments* Presents useful ideas of how to collect the many different Drosophila species in the wild

Book excerpt: This book, dedicated to the influential Danish spider ecologist Edwin Ngaard, contains contributions by authors from 16 European countries, and reflects the current areas of interest for researchers working with spiders, scorpions and related animals in Europe. It contains 46 original research articles and reviews covering a wide range of disciplines such as ecology and conservation, behavior, physiology, morphology and systematics. A particular section is devoted to reproductive behavior, with papers on sexual selection, sperm competition is relation to the structure of female genitalia, emasculation and sexual cannibalism in spiders, and parthenogenesis in scorpions. Silk and the structure and construction of spider webs form another section. There are papers on sampling methods and faunistic analyses of the biodiversity and conservation value of spider communities from several types of habitats (forests, dunes, bogs etc.) in various European countries. Other papers deal with the value of spiders for agriculture, prey capture strategies, spiders parasites, life cycles, neuronal mapping of reflex behavior, the systematic classification of spiders and local faunistics.
