In this book, the biologist Raghavendra Gadagkar focuses on the single species he has worked on throughout his career. His years of study have led him to believe that ecological, physiological, and demographic factors can be more important than genetic relatedness in the selection for or against social traits.

A comprehensive, multi-author treatise on the social insects of the world, with some auxiliary attention to such adjacent topics as subsocial insects and social arachnids. The work is to serve as a very convenient, yet authoritative reference work on the biology and systematics of social insects of the world. This is a project of the International Union for the Study of Social Insects (IUSSI), the worldwide organizing body for the scientific study of social insects.

In this edited collection, 17 internationally known authorities bring together the results of recent research on the natural history, ecology, behavior, morphology, and genetics of wasps as they pertain to the evolution of social behavior. The first part of the book opens with a review of the classification of the family Vespidae along with a revision of the subfamily Polistinae. Seven subsequent chapters deal with the natural history and social biology of each of the major taxa of social and presocial vespids. The second part of the book offers chapters on reproductive competition; worker polyethism; evolution of nest architecture, of queen number and queen control, and of exocrine glands; population genetics; the nutritional bsis of social evolution; and the nest as the locus of social life. The final chapter is a comparative discussion of social behavior in the Sphecidae, the only family of wasps besides the Vespidae in which well-developed social behavior is known. Providing a wealth of information about the biology of wasps, this comprehensive, up-to-date volume will be an essential reference for entomologists, evolutionary biologists, behavioral ecologists, ethologists, and zoologists.

'Social' insects and arachnids exhibit complex forms of behavior that involve cooperation in building a nest, defending against attackers or rearing offspring. This book is a comprehensive, up-to-date guide to sociality and its evolution in a wide range of taxa.

Only in recent years have biologists and ethologists begun to apply careful evolutionary thinking to the study of animal societies--and with spectacular results. This book presents the choicest of these findings, illustrated with both photographs and explanatory diagrams.

How can the stunning diversity of social systems and behaviours seen in nature be explained? Drawing on social evolution theory, experimental evidence and studies conducted in the field, this book outlines the fundamental principles of social evolution underlying this phenomenal richness.To succeed in the competition for resources, organisms may either 'race' to be quicker than others, 'fight' for privileged access, or 'share' their efforts and gains. The authors show how the ecology and intrinsic attributes of organisms select for each of these strategies, and how a handful of straightforward concepts explain the evolution of successful decision rules in behavioural interactions, whether among members of the same or different species. With a broad focus ranging from microorganisms to humans, this is the first book to provide students and researchers with a comprehensive account of the evolution of sociality by natural selection.

This book provides updated information on this intriguing and exciting group of insects: Neotropical Social Wasps. These insects have a particular biology and their colonies are formed by a few cooperative females living in either small or massive, structured nests where stinging individuals organize their activities and defend their offspring. Topics include evolutionary aspects, biogeography, post-embryonic development, community behavior and ecology, economic importance, and research methods.
