Succinct genus and species accounts cover identifying characteristics, breeding, behaviour, distribution and conservation status. Colour photographs and/or illustrations as well as distribution maps support each entry. Introductory chapter discusses spider morphology, spider life cycle, the functions of silk, as well as spider collection techniques. Section on venom identifies species that pose a danger to humans, unpacks neurotoxic and cytotoxic venom, and details the symptoms and treatment of spider bites.

This book was released on 2014-02-20 with total page 433 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the first-ever field guide to provide information on a vast spectrum of spider species based on their morphology, behaviour and distribution. It’s the first book to introduce all 70 South African spider families including 370 major genera and more than 860 of the more common species. It includes illustrations of all of the families, genera and species as well as more than 2 000 colour photographs and 843 maps. - A thorough summary of morphology, biology and habitat requirements is provided - Species with medical importance are discussed - The morphological characters of all known spider families from South Africa are provided and illustrated with notes on their behavior as well as further reading material - Short morphological data with notes on behaviour and distribution of 370 major genera and 860 species is provided This field guide’s purpose is to enable observers to identify spiders in the field. One of the difficulties facing a spider-watcher is that a large number of spider species are small and extremely well camouflaged and are therefore not easily seen. For some genera you will need a magnifying glass or microscope to be able to identify the specimen to generic or species level. Many species can only be identified by a specialist who has access to a good microscope and the relevant literature. Most of the spiders were photographed alive in their natural settings and only some rare and smaller species were photographed using a camera mounted on a microscope. The illustrations and descriptions make it easy for an inexperienced spider-watcher to identify many of the common species encountered in and around the house. The spiders were divided according to the free-living species and those that build intricate webs to catch their prey. The free-living spiders were further divided according to those found on the vegetation and those living on the ground. Spiders are an abundant, diverse and highly successful group of animals. They are commonly found on farms, in gardens and also in houses. They are important predators in all terrestrial ecosystems and are regarded as the “best friends” of gardeners and farmers in sustainable agriculture because they have the important task of regulating the numbers of potentially harmful insects and mites. However, they are feared and maligned because of the venom they produce. We hope this field guide will help save the lives of a few spiders. It will be valuable for the man on the street, researchers, conservation agencies, students, gardeners, farmers, as well as spider-watchers and photographers.

This book was released on 1988 with total page 104 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The American diplurid genus Euagrus, distributed from Arizona south to Costa Rica, is revised for the first time. Euagrus is defined to include those euagrine diplurids with the following character states: no australotheline crescent; terminal cymbial spines; interlocking spinule patches on male femora I and II; a ventral, proximal, nonspatulate, tibia II mating apophysis with one or more large apical spines; two or three ventral mating keels on metatarsus II; no macrosetae brush on the prolateral surface of male tibia II; and two or more sclerotized stalks with unsclerotized bulbs on each (unsclerotized) spermathecal trunk. The relationships of Euagrus to other euagrine genera are discussed. A cladogram (based on outgroup comparison with the sister genus, Phyxioschema), a key, diagnoses, descriptions, tables of quantitative character values, illustrations, analyses of variation, natural history information, locality records, and distribution maps are provided for the 20 recognized species of Euagrus. Eight of these species are newly described: E. carlos, E. charcus, E. garnicus, E. gertschi, E. gus, E. leones, E. rothi, and E. zacus. Six specific names are newly synonymized: E. ravenus Gertsch and Mulaik, E. apacheus Gertsch and Mulaik, and E. ritaensis Chamberlin and Ivie with E. chisoseus Gertsch; E. empiricus Chamberlin and E. scepticus Chamberlin with E. josephus Chamberlin; and E. pragmaticus Chamberlin with E. rubrigularis Simon"--Page 205

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 923 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.
