Evolution Of Sociality In Spiders

'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.

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.

Spiders are often underestimated as suitable behavioural models because of the general belief that due to their small brains their behaviour is innate and mostly invariable. Challenging this assumption, this fascinating book shows that rather than having a limited behavioural repertoire, spiders show surprising cognitive abilities, changing their behaviour to suit their situational needs. The team of authors unravels the considerable intra-specific as well as intra-individual variability and plasticity in different behaviours ranging from foraging and web building to communication and courtship. An introductory chapter on spider biology, systematics and evolution provides the reader with the necessary background information to understand the discussed behaviours and helps to place them into an evolutionary context. Highlighting an under-explored area of behaviour, this book will provide new ideas for behavioural researchers and students unfamiliar with spiders as well as a valuable resource for those already working in this intriguing field.

Social insects and arachnids exhibit forms of complex 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. In it, leading researchers review the extent of sociality in different insect and arachnid groups, analyze the genetic, ecological and demographic causes of sociality from a comparative perspective, and suggest ways in which the field can be better understood. The book contains fascinating accounts of the social lives of many different insects and arachnids, as well as tests of current theories of the evolution of social behavior. The Evolution of Social Behaviour in Insects and Arachnids provides essential reading and insight for students and researchers interested in social behavior, behavioral ecology, entomology, and arachnology.

A comparative view of the major features of animal social life and the evolution of cooperative group living.

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.
