Reproductive Skew in Vertebrates


Book Description

Reproductive skew is the study of how reproduction is partitioned in animal societies. In many social animals reproduction is shared unequally and leads to a reproductive skew among group members. Skew theory investigates the genetic and ecological factors causal to the partitioning of reproduction in animal groups and may yield fundamental insights into the evolution of animal sociality. This book brings together new theory and empirical work, mostly in vertebrates, to test assumptions and predictions of skew models. It also gives an updated critical review of skew theory. The team of leading contributors cover a wide range of species, from insects to humans, and discuss both ultimate (evolutionary) and proximate (immediate) factors influencing reproductive skew. Academic researchers and graduate students alike with an interest in evolution and sociality will find this material stimulating and exciting.

Cooperative Breeding in Vertebrates


Book Description

Brings together long-term studies of cooperation in vertebrates that challenge our understanding of the evolution of social behavior.




Ecology and Evolution of Cooperative Breeding in Birds


Book Description

Cooperative breeders are species in which more than a pair of individuals assist in the production of young. Cooperative breeding is found in only a few hundred bird species world-wide, and understanding this often strikingly altruistic behaviour has remained an important challenge in behavioural ecology for over 30 years. This book highlights the theoretical, empirical and technical advances that have taken place in the field of cooperative breeding research since the publication of the seminal work Cooperative Breeding in Birds: Long-term Studies of Behavior and Ecology (1990, HB ISBN 0521 372984, PB ISBN 0521 378907). Organized conceptually, special attention is given to ways in which cooperative breeders have proved fertile subjects for testing modern advances to classic evolutionary problems including those of sexual selection, sex-ratio manipulation, life-history evolution, partitioning of reproduction and incest avoidance. It will be of interest to both students and researchers interested in behaviour and ecology.




Comparative Vertebrate Reproduction


Book Description

Comparative Vertebrate Reproduction is the only comprehensive textbook covering major topics in the reproductive biology of vertebrates, from sexuality and gametogenesis to reproductive ecology and life history tactics. The work draws heavily on recent reviews and papers while placing topics in a historical context and conceptual framework. In addition, the author provides detailed comparative surveys of each of the major topics discussed. Comparative Vertebrate Reproduction has been written as a textbook for upper-level undergraduate and graduate-level students in biology, zoology, physiology, animal science, and veterinary medicine. The work also serves as an excellent reference for researchers in medical and veterinary schools working in reproductive medicine.




The Reproduction of Vertebrates


Book Description

The Reproduction of Vertebrates describes the vertebrate reproductive systems in an evolutionary sequence and according to taxonomic classes. This book is divided into seven chapters; each chapter tackles a specific vertebrate class. This text specifically considers fish, amphibians, reptiles, birds, mammals, and man. Discussions in each chapter include these species’ evolutionary history, classification, external indications of sex, mating, fertilization, development, endocrinology, breeding seasons, sexual maturation, migration, response to environmental factors, and economic importance. The concluding chapter presents the comparative aspects of reproduction of these vertebrates. This text is of great value to teachers and students who are interested in the vertebrate reproductive system.







Cooperative Breeding in Vertebrates


Book Description

Cooperative breeders are species in which individuals beyond a pair assist in the production of young in a single brood or litter. Although relatively rare, cooperative breeding is widespread taxonomically and continues to pose challenges to our understanding of the evolution of cooperation and altruistic behavior. Bringing together long-term studies of cooperatively breeding birds, mammals, and fish, this volume provides a synthesis of current studies in the field. The chapters are organised by individual studies of particular species or (in the case of mole-rats) two closely related cooperatively breeding species. Each focuses not only on describing behavior and ecology but also on testing evolutionary hypotheses for the form and function of the diverse and extraordinary cooperative breeding lifestyles that have been discovered. This unique and comprehensive text will be of interest to graduate students and researchers of behavioral ecology and the evolution of cooperation.




Conceptual Breakthroughs in Ethology and Animal Behavior


Book Description

Conceptual Breakthroughs in Ethology and Animal Behavior highlights, through concise summaries, the most important discoveries and scientific revolutions in animal behavior. These are assessed for their relative impact on the field and their significance to the forward motion of the science of animal behavior. Eighty short essays capture the moment when a new concept emerged or a publication signaled a paradigm shift. How the new understanding came about is explained, and any continuing controversy or scientific conversation on the issue is highlighted. Behavior is a rich and varied field, drawing on genetics, evolution, physiology, and ecology to inform its principles, and this book embraces the wealth of knowledge that comes from the unification of these fields around the study of animals in motion. The chronological organization of the essays makes this an excellent overview of the history of animal behavior, ethology, and behavioral ecology. The work includes such topics as Darwin’s role in shaping the study of animal behavior, the logic of animal contests, cognition, empathy in animals, and animal personalities. Succinct accounts of new revelations about behavior through scientific investigation and scrutiny reveal the fascinating story of this field. Similar to Dr. John Avise’s Contemporary Breakthroughs in Evolutionary Genetics, the work is structured into vignettes that describe the conceptual revolution and assess the impact of the conceptual change, with a score, which ranges from 1-10, providing an assessment of the impact of the new findings on contemporary science. Features a lively, brisk writing style and brief entries to enable easy, enjoyable access to this essential information Includes topics that cover the range of behavioral biology from mechanism to behavioral ecology Can also be used as supplemental material for an undergraduate animal behavior course, or as the foundational text for an upper level or graduate discussion course in advanced animal behavior




Mammal Societies


Book Description

The book aims to integrate our understanding of mammalian societies into a novel synthesis that is relevant to behavioural ecologists, ecologists, and anthropologists. It adopts a coherent structure that deals initially with the characteristics and strategies of females, before covering those of males, cooperative societies and hominid societies. It reviews our current understanding both of the structure of societies and of the strategies of individuals; it combines coverage of relevant areas of theory with coverage of interspecific comparisons, intraspecific comparisons and experiments; it explores both evolutionary causes of different traits and their ecological consequences; and it integrates research on different groups of mammals with research on primates and humans and attempts to put research on human societies into a broader perspective.
