Book Description
This authoritative catalogue will greatly assist readers in finding the correct taxonomic name for any given family, genus or species within each of the six arachnid orders treated. It contains a valuable summary of bibliographic information, enabling readers to access the worldwide literature for these smaller orders. The catalogue presents full bibliographic data on each of the taxa named thus far, treating over 1600 species. It contains the most current classification system for each group, some of which have not been catalogued on a world scale for over 70 years. A summary of taxonomic changes is included. This quality reference will be of immense value to arachnologists, systematists, taxonomists, ecologists and biodiversity professionals, especially those interested in tropical rainforest communities.

Book Description
This volume merges all geographical and paleogeographical data on all groups of the arachnofauna. The book features topics such as the ecological factors, climate and other barriers that influence the distribution of arachnida. It also elaborates on the characteristics of the distribution such as arachnida at high altitude (e.g. Himalaya), in caves, in polar regions and highlights differences between the arachnofauna of e.g. Mediterranean regions vs Central Europe, West African vs Indomalayan and more. Furthermore, amongst other topics the volume also includes chapters on the systems of arachnida, fossil orders, dispersal and dispersion, endemics and relicts, regional arachnogeography, cave and high altitude arachnida.

Book Description
Paleontologists and geologists struggle with research questions often complicated by the loss or even absence of key paleobiological and paleoenvironmental information. Insight into this missing data can be gained through direct exploration of analogous living organisms and modern environments. Creative, experimental and interdisciplinary treatments of such ancient-Earth analogs form the basis of Lessons from the Living. This volume unites a diverse range of expert paleontologists, neontologists and geologists presenting case studies that cover a spectrum of topics, including functional morphology, taphonomy, environments and organism-substrate interactions.

Book Description
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.

Book Description
Contemporary research in the field of evolutionary developmental biology, or 'evo-devo', has to date been predominantly devoted to interpreting basic features of animal architecture in molecular genetics terms. Considerably less time has been spent on the exploitation of the wealth of facts and concepts available from traditional disciplines, such as comparative morphology, even though these traditional approaches can continue to offer a fresh insight into evolutionary developmental questions. The Development of Animal Form aims to integrate traditional morphological and contemporary molecular genetic approaches and to deal with post-embryonic development as well. This approach leads to unconventional views on the basic features of animal organization, such as body axes, symmetry, segments, body regions, appendages and related concepts. This book will be of particular interest to graduate students and researchers in evolutionary and developmental biology, as well as to those in related areas of cell biology, genetics and zoology.

Book Description
Fossil arachnids date back more than 400 million years to the Silurian period, making them one of the first animal groups to appear in terrestrial ecosystems. This book provides information on what the arachnids are and their relationships to one another.

Book Description
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.
