Download or read book The velvet spiders an atlas of the Eresidae Arachnida Araneae written by Jeremy A. Miller and published by PenSoft Publishers LTD. This book was released on 2012-05-18 with total page 152 pages. Available in PDF, EPUB and Kindle. Book excerpt: The name velvet spider describes the dark and shiny appearance of members of the family Eresidae. Some species also have brightly-colored highlights, such as the red, white, and black ladybird spiders of Europe and North Asia. This family also includes some of the world?s most cooperative spider species. Social species can be very abundant in parts of tropical Africa and Asia with conspicuous colonies dotting the landscape. Social colonies may consist of hundreds of closely-related individuals that participate in dramatic mass attacks on prey and care for their young. The ecology of these social species is fascinating and has been the subject of several landmark scientific papers. By contrast, most kinds of velvet spider are rarely encountered. Most species keep well hidden or dig burrows and live underground. This monograph provides a generic-level review of Eresidae documented with collections of photographs, scanning electron micrographs, and illustrations. A key to the nine genera and other major lineages is provided. A new phylogeny of Eresidae based on molecular sequence data expands on a previously published analysis. Cybertaxonomic enhancements include an interactive map of the specimens used in the study explorable using Google Earth, specimen records uploaded to GBIF, and molecular sequence alignments and other data archived on Dryad. An EDIT Integrated Research grant provided principal funding for this project.
Download or read book Phylogenetic Supertrees written by Olaf R.P. Bininda-Emonds and published by Springer Science & Business Media. This book was released on 2004-05-31 with total page 547 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the first book on "phylogenetic supertrees", a recent, but controversial development for inferring evolutionary trees. Rather than analyze the combined primary character data directly, supertree construction proceeds by combining the tree topologies derived from those data. This difference in strategy has allowed for the exciting possibility of larger, more complete phylogenies than are otherwise currently possible, with the potential to revolutionize evolutionarily-based research. This book provides a comprehensive look at supertrees, ranging from the methods used to build supertrees to the significance of supertrees to bioinformatic and biological research. Reviews of many the major supertree methods are provided and four new techniques, including a Bayesian implementation of supertrees, are described for the first time. The far-reaching impact of supertrees on biological research is highlighted both in general terms and through specific examples from diverse clades such as flowering plants, even-toed ungulates, and primates. The book also critically examines the many outstanding challenges and problem areas for this relatively new field, showing the way for supertree construction in the age of genomics. Interdisciplinary contributions from the majority of the leading authorities on supertree construction in all areas of the bioinformatic community (biology, computer sciences, and mathematics) will ensure that this book is a valuable reference with wide appeal to anyone interested in phylogenetic inference.
Download or read book Spider Ecophysiology written by Wolfgang Nentwig and published by Springer Science & Business Media. This book was released on 2013-02-15 with total page 509 pages. Available in PDF, EPUB and Kindle. Book excerpt: With over 43,000 species, spiders are the largest predacious arthropod group. They have developed key characteristics such as multi-purpose silk types, venoms consisting of hundreds of components, locomotion driven by muscles and hydraulic pressure, a highly evolved key-lock mechanism between the complex genital structures, and many more unique features. After 300 million years of evolutionary refinement, spiders are present in all land habitats and represent one of the most successful groups of terrestrial organisms. Ecophysiology combines functional and evolutionary aspects of morphology, physiology, biochemistry and molecular biology with ecology. Cutting-edge science in spiders focuses on the circulatory and respiratory system, locomotion and dispersal abilities, the immune system, endosymbionts and pathogens, chemical communication, gland secretions, venom components, silk structure, structure and perception of colours as well as nutritional requirements. Spiders are valuable indicator species in agroecosystems and for conservation biology. Modern transfer and application technologies research spiders and their products with respect to their value for biomimetics, material sciences, and the agrochemical and pharmaceutical industries.

Download or read book The Evolution of Primary Sexual Characters in Animals written by Janet Leonard and published by Oxford University Press. This book was released on 2010-07-19 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.

This book was released on 2012 with total page 76 pages. Available in PDF, EPUB and Kindle. Book excerpt: or synonyms of Menneus as their type species are nested throughout Menneus phylogeny. The second goal is to revise the non-Deinopis species of Deinopidae. Here, we recognize, diagnose, illustrate, describe, and phylogenetically place the 14 known Menneus species. Africa currently has six species: Menneus camelus Pocock, 1902, from South Africa; M. capensis (Purcell, 1904) new combination from Western Cape, South Africa; M. darwini new species from Tanzania; M. dromedarius Purcell, 1904 (removed from synonymy of M. camelus), from South Africa and Madagascar; M. samperi new species from Kenya, Tanzania, and Uganda; and M. tetragnathoides Simon, 1876 (M. affinis Tullgren, 1910 new synonym), from Angola, Malawi, and Tanzania.
