This book is a snapshot of the current state of the art of research and development on the properties and characteristics of silk and their use in medicine and industry. The field encompasses backyard silk production from ancient time to industrial methods in the modern era and includes an example of efforts to maintain silk production on Madagascar. Once revered as worth its weight in gold, silk has captured the imagination from its mythical origins onwards. The latest methods in molecular biology have opened new descriptions of the underlying properties of silk. Advances in technological innovation have created silk production by microbes as the latest breakthrough in the saga of silk research and development. The application of silk to biomaterials is now very active on the basis of excellent properties of silks including recombinant silks for biomaterials and the accumulated structural information.

Concentrating on the complex spider communication system, this book assembles the most recent multidisciplinary advances of leading researchers from many countries to assess the peculiar role spiders play in the animal kingdom. Originally published in 1982. The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press. These editions preserve the original texts of these important books while presenting them in durable paperback and hardcover editions. The goal of the Princeton Legacy Library is to vastly increase access to the rich scholarly heritage found in the thousands of books published by Princeton University Press since its founding in 1905.

This work takes a fresh, modern approach to investigate and explain the predator and prey relationships of insects and spiders, the major terrestrial fauna on earth. Devoted to broad and in-depth analysis of arthropod defenses against predators, the book's approach is both experimentally and theoretically based with major emphasis on evolution, predator strategies and tactics, and prey defensive adaptations and behaviors. The authors explain such topics as cryptic and aposematic coloration, the conflict between sexual and survival needs, web spider prey choice and evolution of prey counter defenses, predator-prey interactions and the origins of intelligence, bird predatory tactics, and caterpillar defense strategies. Also examined is the use of timing for fitness and survival, evolutionary gamesmanship in the predatory bat-moth relationship, colony defense by aper wasps, startle as a defense by moths, aggregation as a defense, chemicals as defenses, plant chemicals as defenses, and venoms as defenses. The authors illustrate each topic with numerous specific well-documented examples presented in a clear, readable style.

Spiders have made a real success of life on dry land, and the influence of their numbers on the evolution of insects is vividly described. This edition is exclusive to newnaturalists.com There have been a number of books on spiders, but the Editors consider that in this book they are offering something new and outstandingly important. Mr. Bristowe is one of the many distinguished amateurs who have contributed so much to our natural history; he has indeed done more than any other person to put spiders on the map by watching and experimenting with them - in fact by exploring the world in which they live. He writes brilliantly, fluently and with an enthusiasm that is soon passed on to the reader. From the first chapter, dealing with spiders in literature and superstition, to the last, on collecting spiders, he blends wisdom with wit. Whilst disclosing the marvels of spider life, he adopts an evolutionary approach which takes him back to early beginnings in the Devonian epoch in his search for explanations of their present structure and habits. Spiders have made a real success of life on dry land, and the influence of their numbers on the evolution of insects is vividly described. We are introduced to each Family in turn, and are shown what they look like, their amazing ingenuity in catching their prey, their unique courtship and many other characteristics. His descriptions are illustrated by 232 drawings both in line and wash by Arthur Smith, and these must rank in beauty and accuracy with any which have been published hitherto.

Arthropod venoms have received much attention and have played an important role in folklore and medicine since ancient times. Scorpion envenomation, "tarant ism," bee and wasp stings are among those subjects about which most has been speculated and written in the past. In the last 50 years or so, a great number of scientific papers have been devoted to arthropod venoms, but only a few volumes have been designed to collect this rapidly increasing material, and these are not recent. Of late, the chemistry and mode of action of several arthropod venoms have been thoroughly studied, and some of these substances will probably be used as pharmacological tools and also as therapeutic agents. The aim of the present volume is to collect in manual form new information as well as the old notions on arthropod venoms. Even though it was our intention to present a volume on arthropod venoms, and not on venomous arthropods, inevitably we were forced to include information on venom-producing organisms as well. We assumed, in fact, that those scientists for whom the present manual is primarily intended (biochemists, particularly com parative biochemists, and pharmacologists) should be familiar with the biologic elements concerning the venom-producing species; which should show them how important it is to operate in close collaboration with biologists specialized in venomous arthropod systematics and biology.
