Book excerpt: Whip spiders (Amblypygi) can be large and terrifying animals with strong, raptorial pedipalps and long antenniform first legs that can produce a span of as much as 60 cm. Others are small and scarcely span 5 cm. They all lead a secretive nocturnal life and are extremely dangerous to other arthropods and small vertebrates. In contrast to spiders and scorpions, they are of no commercial, economic or medical importance and they are difficult to study in the field because of their nocturnal habits, possible reasons why they have been greatly neglected until recently, by scientists and naturalists. Whip spiders represent an old group that dates back to the Carboniferous period. Their partly primitive and partly derived morphological characters and habits make the study of these animals interesting, while observation of their behaviour greatly increases our knowledge and understanding of arachnids in general. In this book the author describes their morphology and systematics, their life history, their fascinating sensory biology, their complex mating dances and reproductive biology, and their ecology and distribution. Thus he has made a significant contibution to a better understanding of the morphology and biology of the Arachnida as a whole. Whip Spiders is an outstanding contribution to science and it will be of interest for anyone with an interest in Arachnida and for those keeping and breeding spiders.

Download or read book Invasive Species and Human Health written by Giuseppe Mazza and published by CABI. This book was released on 2018-07-13 with total page 210 pages. Available in PDF, EPUB and Kindle. Book excerpt: Invasive alien plants and animals are known for their disruption of ecosystems and threat to biodiversity. This book highlights their major impact on human health. This includes not only direct effects through contact with the species via bites, wounds and disease, but also indirect effects caused by changes induced in ecosystems by invasive species, such as more water hyacinth increasing mosquito levels and thereby the potential for malaria. Covering a wide range of case studies from different taxa (animals and plants), and giving an overview of the diverse impacts of invasive species on health in developed and developing countries, the book is a significant contribution that will help in prioritizing approaches to controlling invasive species and mitigating their health effects. It covers invasive plants, marine species, spiders and other arachnids, ticks and dust mites, insects, mosquitos and other diptera, freshwater species (invertebrates and fishes), amphibians and reptiles, birds and mammals. The broad spectrum of the analyzed case studies will ensure the appeal of the book to a wide public, including researchers of biological invasions, doctors, policy-makers and managers, and students of invasive species in ecology, animal and plant biology and public health medicine.
Download or read book Neurobiology of Arachnids written by F.G. Barth and published by Springer Science & Business Media. This book was released on 2013-11-11 with total page 388 pages. Available in PDF, EPUB and Kindle. Book excerpt: Arachnids rarely come to mind when one discusses arthropod neurobiology. In fact much more is now known and written about the nervous systems of insects and crustaceans. Several arguments have led us to conclude, however, that the time has come to document impor tant aspects of the neurobiology of spiders, scorpions, and their kin, as well. Studies of arachnid neurobiology have made considerable progress since the last comprehensive treatment by Bullock and Horridge in their monumental monograph on invertebrate nervous systems pub lished in 1965. This is especially true for research performed in the last decade. Several problems related to the structure and function of arachnid nervous and sensory systems have now been studied in con siderable depth but have so far not been given adequate space under one cover. A particular incentive to produce this book has been the impor tance attributed to comparative approaches in neurobiology. Neglect ing a large taxonomic group such as the arachnids - which comprises some 60,000 species living a wide range of different lives - would mean ignoring an enormous potential source of knowledge. In writing the chapters of this book we have striven to present some of the unique features of the arachnids. But the result of our efforts is not just meant to contribute to an understanding of the particularities of the arach nids.
Download or read book Female Control written by William G. Eberhard and published by Princeton University Press. This book was released on 1996 with total page 532 pages. Available in PDF, EPUB and Kindle. Book excerpt: Evidence from various fields indicates that such selectivity by females may be the norm rather than the exception. Because most postcopulatory competition among males for paternity is played out within the bodies of females, female behavior, morphology, and physiology probably often influence male success in these contests, Eberhard draws examples from a diversity of organisms, ranging from ctenophores to scorpions, nematodes to frogs, and crickets to humans.
Download or read book Mating Systems and Strategies written by Stephen M. Shuster and published by Princeton University Press. This book was released on 2019-12-31 with total page 546 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents the first unified conceptual and statistical framework for understanding the evolution of reproductive strategies. Using the concept of the opportunity for sexual selection, the authors illustrate how and why sexual selection, though restricted to one sex and opposed in the other, is one of the strongest and fastest of all evolutionary forces. They offer a statistical framework for studying mating system evolution and apply it to patterns of alternative mating strategies. In doing so, they provide a method for quantifying how the strength of sexual selection is affected by the ecological and life history processes that influence females' spatial and temporal clustering and reproductive schedules. Directly challenging verbal evolutionary models that attempt to explain reproductive behavior without quantitative reference to evolutionary genetics, this book establishes a more solid theoretical foundation for the field. Among the weaknesses the authors find in the existing data is the apparent ubiquity of condition-dependent mating tactics. They identify factors likely to contribute to the evolution of alternative mating strategies--which they argue are more common than generally believed--and illustrate how to measure the strength of selection acting on them. Lastly, they offer predictions on the covariation of mating systems and strategies, consider the underlying developmental biology behind male polyphenism, and propose directions for future research. Informed by genetics, this is a comprehensive and rigorous new approach to explaining mating systems and strategies that will influence a wide swath of evolutionary biology.
Download or read book The Biology of Camel Spiders written by Fred Punzo and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 304 pages. Available in PDF, EPUB and Kindle. Book excerpt: My initial interest in the Solifugae (camel-spiders) stems from an incident that occurred in the summer of 1986. I was studying the behavioral ecology of spider wasps of the genus Pepsis and their interactions with their large theraphosid (tarantula) spider hosts, in the Chihuahuan Desert near Big Bend National Park, Texas. I was monitoring a particular tarantula burrow one night when I noticed the resident female crawl up into the burrow entrance. Hoping to take some photographs of prey capture, I placed a cricket near the entrance and waited for the spider to pounce. Suddenly, out of the comer of my eye appeared a large, rapidly moving yellowish form which siezed the cricket and quickly ran off with it until it disappeared beneath a nearby mesquite bush. So suddenly and quickly had the sequence of events occurred, that I found myself momentarily startled. With the aid of a headlamp I soon located the intruder, a solifuge, who was already busy at work macerating the insect with its large chelicerae (jaws). When I attempted to nudge it with the edge of my forceps, it quickly moved to another location beneath the bush. When I repeated this maneuver, the solifuge dropped the cricket and lunged at the forceps, gripping them tightly in its jaws, refusing to release them until they were forcefully pulled away.

Book excerpt: 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.
Download or read book Alternative Reproductive Tactics written by Brockmann H Jane Taborsky Michael Oliveira Rui F and published by . This book was released on 2014-05-14 with total page 519 pages. Available in PDF, EPUB and Kindle. Book excerpt: The study of alternative reproductive tactics (the behavioural strategies used by individuals to increase their reproductive success) is an evolutionary puzzle, and one of great interest to researchers. For instance, why do some males guard both nest and eggs, while others sneak into nests while pairs are spawning and fertilise those eggs? The field offers a special opportunity to study the evolution and functional causes of phenotypic variation, which is a general problem in the field of evolutionary biology. By integrating both mechanistic (psychological) and evolutionary (behavioural ecology) perspectives and by covering a great diversity of species, Alternative Reproductive Tactics addresses this integrated topic of longstanding interest, bringing together a multitude of otherwise scattered information in an accessible form that is ideal for graduate students and researchers.
