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.

Available in PDF, EPUB and Kindle. Book excerpt: Recently another book on insect physiology was published. It was restricted to a few focal points as are many of these new insect physiology books, but there was considerable depth in its specialized point of view. We were dis cussing the structure of this book and of insect physiology books, in general, when Prof. Remmert asked me " . . . and what about books on spider physio logy?" Silence. Then I started to explain "oh yes, there is a congress pro ceedings volume on this topic and there is a group with excellent publica tions on another topic . . . ", but I felt that this answer was weak. One can no longer buy the proceedings volume in a bookshop and to read a series of publications on a given topic one must search in a library for a dozen journals. Why is there not a single book on spider physiology comparable with the many books on insect physiology? Are spiders a scientific ivory tower, far from public interest and commercial importance? I do not think so, although spiders are one of the many "forgotten" animal groups which always grew in the shadow of the insects. There are research groups working on spider physiology, there are fascinating phenomena in this animal group and there are plenty of exciting results. Spiders may have been always underresearch ed, but research is progressing. In the last few years, new books have been published, e. g.

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.

Download or read book Britain's Spiders written by Lawrence Bee and published by Princeton University Press. This book was released on 2017-06-27 with total page 480 pages. Available in PDF, EPUB and Kindle. Book excerpt: Britain’s Spiders is a photographic guide to all 37 of the British families, focussing on spiders that can be identified in the field. Illustrated with a remarkable collection of photographs, it is designed to be accessible to a wide audience, including those new to spider identification. This book pushes the boundaries of field identification for this challenging group by combining information on features that can be seen with the naked eye or a hand lens with additional evidence from webs, egg-sacs, behaviour, phenology, habitats and distributions. Individual accounts cover 395 of Britain’s approximately 670 species, with the limitations to field identification clearly explained. As the first photographic field guide to British spiders to be published since 1989, this book fills a major gap in the resources available to everyone with an interest in this fascinating, diverse and important group of animals. More than 700 stunning photographs Includes a guide to spider families, based on features recognisable in the field, focussing on body shape and other characteristics, as well as separate guides to webs and egg-sacs Detailed accounts highlight key identification tips for each genus and species, and include information on status, behaviour and habitats Features up-to-date distribution maps, and charts showing adult seasonality Introductory chapters explore the biology of spiders, and where, when and how to find them, including equipment needed in the field Contains a complete list of the spiders recorded in Britain, indicating the ease of identification as well as rarity and conservation status Provides information on how to record spiders and make your records count, and guidance on how to take your interest further

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.
