Ants are among the most conspicuous and the most ecologically important of insects. This concise, easy-to-use, authoritative identification guide introduces the fascinating and diverse ant fauna of the United States and Canada. It features the first illustrated key to North American ant genera, discusses distribution patterns, explores ant ecology and natural history, and includes a list of all currently recognized ant species in this large region. * New keys to the 73 North American ant genera illustrated with 250 line drawings ensure accurate identification * 180 color images show the head and profile of each genus and important species groups * Includes a glossary of important terms
From the Arctic to South Africa - one finds them everywhere: Ants. Making up nearly 15% of the entire terrestrial animal biomass, ants are impressive not only in quantitative terms, they also fascinate by their highly organized and complex social system. Their caste system, the division of labor, the origin of altruistic behavior and the complex forms of chemical communication makes them the most interesting group of social organisms and the main subject for sociobiologists. Not least is their ecological importance: Ants are the premier soil turners, channelers of energy and dominatrices of the insect fauna.

This second updated volume on breast cancer provides a comprehensive overview of its clinical management and current therapies. Updated to reflect the changes in breast cancer staging, the progress in immunotherapy approaches, as well as the latest guidelines for therapies, this book brings readers up to speed with the latest therapeutic regimens in breast cancer and provides an in-depth account of current and new therapeutic approaches. The most important phase III trials, high quality meta-analysis, consensus reports and guidelines are extensively discussed in this new edition and provide the reader with the most up-to-date information. Divided in themed parts, the book examines invasive b...
This book provides a rigorous look at the mechanisms underlying collective behavior in social insects. The field is developing rapidly, and the book includes up-to-date research from biology, neuroscience, artificial intelligence, robotics, operations research, and computer graphics.
West-Eberhard is widely recognized as one of the most incisive thinkers in evolutionary biology. This book assesses all the evidence for our current understanding of the role of changes in body plan and development for the process of speciation. The process of evolution is systematically reassessed to integrate the insights coming from developmental genetics. Every serious student of evolution, and a substantial share of developmental biologists and geneticists, will need to take note of this contribution. The timing is clearly ripe for the synthesis that this work will help bring about.
Communication is essential for all forms of social interaction from parental care, to mate choice to cooperation. This book is a timely and novel synthesis. It bridges many of the gaps between proximate and ultimate levels of analysis, between empirical model systems, and between biology and the humanities. The book offers the complementary approaches of a distinguished group of authors spanning a large diversity of research programs, addressing, for example, thegenetic basis of bacterial communication, dishonest communication in insect societies, sexual selection and network communication among colonial vertebrates. Other chapters explore the role ofcommunication in genomic conflict and self-organisation, and how linguistics, psychology and philosophy may ultimately contribute to a biological understanding of human mate choice and the evolution of human societies.
Claire Detrain, Jean-Louis Deneubourg and Jacques Pasteels Studies on insects have been pioneering in major fields of modern biology. In the 1970 s, research on pheromonal communication in insects gave birth to the dis cipline of chemical ecology and provided a scientific frame to extend this approach to other animal groups. In the 1980 s, the theory of kin selection, which was initially formulated by Hamilton to explain the rise of eusociality in insects, exploded into a field of research on its own and found applications in the under standing of community structures including vertebrate ones. In the same manner, recent studies, which decipher the collective behaviour of insect societies, m...
