Book Synopsis Field Guide to the Spiders of California and the Pacific Coast States by : Richard J. Adams
Download or read book Field Guide to the Spiders of California and the Pacific Coast States written by Richard J. Adams and published by Univ of California Press. This book was released on 2014-01-28 with total page 454 pages. Available in PDF, EPUB and Kindle. Book excerpt: With over 40,000 described species, spiders have adapted to nearly every terrestrial environment across the globe. Over half of the world’s spider families live within the three contiguous Pacific Coast states—not surprising considering the wide variety of habitats, from mountain meadows and desert dunes to redwood forests and massive urban centers. This beautifully illustrated, accessible guide covers all of the families and many of the genera found along the Pacific Coast, including introduced species and common garden spiders. The author provides readers with tools for identifying many of the region’s spiders to family, and when possible, genus and species. He discusses taxonomy, distribution, and natural history as well as what is known of the habits of the spiders, the characters of families, and references to taxonomic revisions of the pertinent genera. Full-color plates for each family bring to life the incredible diversity of this ancient arachnid order.
Book Synopsis Focus on Biodiversity Research by : Jan Schwartz
Download or read book Focus on Biodiversity Research written by Jan Schwartz and published by Nova Publishers. This book was released on 2007 with total page 340 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biological diversity, or "biodiversity," refers to the variety of all life on earth, and the complex relationships among living things, and between living things and their environment. Biodiversity includes genetic variety, species diversity, and variability in communities, ecosystems and landscapes. Biodiversity sustains the environments in which we live and on which our lives and those of every other living creature on Earth depend. Thanks to biodiversity, we are able to obtain such necessary goods as food, clothing, medicine, and fuel. Equally important are the ecosystem services that biodiversity provides, such as clean air and drinkable water. Conservation scientists have identified a number of universal threats to biodiversity: habitat loss and degradation, invasive species, pollution, overpopulation, overexploitation and consumption, and global climate change. This book examines critical issues in this field from researchers around the globe.
Download or read book Spider Webs written by William Eberhard and published by University of Chicago Press. This book was released on 2020-12-22 with total page 679 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this lavishly illustrated, first-ever book on how spider webs are built, function, and evolved, William Eberhard provides a comprehensive overview of spider functional morphology and behavior related to web building, and of the surprising physical agility and mental abilities of orb weavers. For instance, one spider spins more than three precisely spaced, morphologically complex spiral attachments per second for up to fifteen minutes at a time. Spiders even adjust the mechanical properties of their famously strong silken lines to different parts of their webs and different environments, and make dramatic modifications in orb designs to adapt to available spaces. This extensive adaptive flexibility, involving decisions influenced by up to sixteen different cues, is unexpected in such small, supposedly simple animals. As Eberhard reveals, the extraordinary diversity of webs includes ingenious solutions to gain access to prey in esoteric habitats, from blazing hot and shifting sand dunes (to capture ants) to the surfaces of tropical lakes (to capture water striders). Some webs are nets that are cast onto prey, while others form baskets into which the spider flicks prey. Some aerial webs are tramways used by spiders searching for chemical cues from their prey below, while others feature landing sites for flying insects and spiders where the spider then stalks its prey. In some webs, long trip lines are delicately sustained just above the ground by tiny rigid silk poles. Stemming from the author’s more than five decades observing spider webs, this book will be the definitive reference for years to come.

This book was released on 2005 with total page 840 pages. Available in PDF, EPUB and Kindle. Book excerpt: La publicación recoge los estudios desarrollados en la región de bahía honda. Dichos estudios intentan abordar los grupos de mayor interés. En el medio terrestre fueron objeto de investigación las plantas, algunos invertebrados, y todos los vertebrados. Pero por desgracia, hemos tenido que dejar para mejor ocasión los estudios marinos; la causa no fue otra que la carencia de las garantías mínimas de seguridad, al no disponer todavía en la zona de infraestructura adecuada para el equipo de buceo

Book Synopsis Behaviour and Ecology of Spiders by : Carmen Viera
Download or read book Behaviour and Ecology of Spiders written by Carmen Viera and published by Springer. This book was released on 2017-11-02 with total page 448 pages. Available in PDF, EPUB and Kindle. Book excerpt: Within the last few decades, arachnology in the Neotropical region has experienced a great development filling the knowledge gap in one of the most diverse regions of the world. Nevertheless, large geographical areas remain poorly sampled, especially within the Amazon, and new genera and species have been continuously discovered, even in urban areas. In congruence with the recent improvements in research, several aspects of the ecology, behaviour and natural history of spiders, such as interactions with other predators and parasitoids, social interactions, dispersal patterns, habitat requirements, mating behaviors, among others, are being carefully investigated. These recent contributions incorporate substantial information on the preexisting knowledge on these subjects every year. Our main objective with this book is to present a summary on these new researches and on the currently knowledge on the main subjects involved in the general theme, emphasizing the contribution of the rich fauna of the Neotropical region to the research of behaviour and ecology of the spiders.

Book Synopsis Phylogenetics and Ecology by : Paul Eggleton
Download or read book Phylogenetics and Ecology written by Paul Eggleton and published by Academic Press. This book was released on 1994-11-10 with total page 400 pages. Available in PDF, EPUB and Kindle. Book excerpt: The relationship between systematics and ecology has recently been invigorated, and developed a long way from the "old" field of comparative biology. This change has been two-fold. Advances in phylogenetic research have allowed explicit phylogenetic hypotheses to be constructed for a range of different groups of organisms, and ecologists are now more aware that organism traits are influenced by the interaction of past and present. This volume discusses the impact of these modern phylogenetic methods on ecology, especially those using comparative methods. Although unification of these areas has proved difficult, a number of conclusions can be drawn from the text. These include the need for a "working" bridge between evolutionary biologists using logic-based cladistic methods and those using probability-based statistical methods, for care in the selection of tree types for comparative studies and for systematists to attempt to analyse ecologically important groups. Comparative ecologists and systematists need to come together to develop these ideas further, but this volume presents a very useful starting point for all those interested in systematics and ecology.
