What role does playful behaviour and playful thought take in animal and human development? How does play relate to creativity and, in turn, to innovation? Unravelling the different meanings of 'play', this book focuses on non-aggressive playful play. The authors emphasise its significance for development and evolution, before examining the importance of playfulness in creativity. This discussion sheds new light on the links between creativity and innovation, distinguishing between the generation of novel behaviour and ideas on the one hand, and the implementation of these novelties on the other. The authors then turn to the role of play in the development of the child and to parallels between play, humour and dreaming, along with the altered states of consciousness generated by some psychoactive drugs. A final chapter looks forward to future research and to what remains to be discovered in this fascinating and important field.

Darwin famously described special difficulties in explaining social evolution in insects. More than a century later, the evolution of sociality - defined broadly as cooperative group living - remains one of the most intriguing problems in biology. Providing a unique perspective on the study of social evolution, this volume synthesizes the features of animal social life across the principle taxonomic groups in which sociality has evolved. The chapters explore sociality in a range of species, from ants to primates, highlighting key natural and life history data and providing a comparative view across animal societies. In establishing a single framework for a common, trait-based approach towards social synthesis, this volume will enable graduate students and investigators new to the field to systematically compare taxonomic groups and reinvigorate comparative approaches to studying animal social evolution.

The mammalian neurohypophyseal peptide hormones oxytocin and vasopressin act to mediate human social behavior - they affect trust and social relationships and have an influence on avoidance responses. Describing the evolutionary roots of the effects that these neuropeptides have on behavior, this book examines remarkable parallel findings in both humans and non-human animals. The chapters are structured around three key issues: the molecular and neurohormonal mechanisms of peptides; phylogenetic considerations of their role in vertebrates; and their related effects on human behavior, social cognition and clinical applications involving psychiatric disorders such as autism. A final chapter summarizes current research perspectives and reflects on the outlook for future developments. Providing a comparative overview and featuring contributions from leading researchers, this is a valuable resource for graduate students, researchers and clinicians in this rapidly developing field.

Plants provide insects with a range of specific foods, such as nectar, pollen and food bodies. In exchange, they may obtain various services from arthropods. The role of food rewards in the plant-pollinator mutualism has been broadly covered. This book, first published in 2005, addresses another category of food-mediated interactions, focusing on how plants employ foods to recruit arthropod 'bodyguards' as a protection against herbivores. Many arthropods with primarily carnivorous lifestyles require plant-provided food as an indispensable part of their diet. Only recently have we started to appreciate the implications of non-prey food for plant-herbivore-carnivore interactions. Insight into this aspect of multitrophic interactions is not only crucial to our understanding of the evolution and functioning of plant-insect interactions in natural ecosystems, it also has direct implications for the use of food plants and food supplements in biological control programs. This edited volume provides essential reading for all researchers interested in plant-insect interactions.

Insect Symbiosis is a collection of chapters written by world authorities on the microbes that can be called symbionts that are associated with insects and mites. Whether bacteria, fungi or spiroplasmids, and whether endosymbionts or casual gut symbionts, the authors describe some of the latest work in a field that has grown rapidly since the development of the newer molecular methods, which allowed for the identification of even minute samples of microbes without the need for culturing.

This reference summarizes the current knowledge of the relationship between symbiotic organisms and their insect hosts and provides an unparalleled analysis of cutting-edge research on this issue. Findings from international experts reveal possible new ways to control disease-carrying insects and agricultural pests worldwide. An examination of Wolbachia, considered by many as a vehicle to deliver anti-malarial and anti-plant virus strategies, is also included. Insect Symbiosis serves as a great reference on host-parasitic relationships for professionals from a broad range of fields.

The foraging mode of lizards has been a central theme in guiding research in lizard biology for three decades. Foraging mode has been shown to be a pervasive evolutionary force molding the diet, ecology, behavior, anatomy, biomechanics, life history, and physiology of lizards. This 2007 volume reviews the knowledge on the effects of foraging mode on these and other organismal systems to show how they have evolved, over a wide taxonomic survey of lizard groups. The reviews presented here reveal the continuous nature of foraging strategies in lizards and snakes, providing the reader with a review of the field, and will equip researchers with fresh insights and directions for the sit-and-wait vs. wide foraging paradigm. This will serve as a reference book for herpetologists, evolutionary biologists, ecologists and animal behaviorists.

Originally published in 1988, this title explores and contrasts means and ends psychology with conventional psychology - that of stimuli and response. The author develops this comparison by exploring the general nature of psychological phenomena and clarifying many persistent doubts about psychology. She contrasts conventional psychology (stimuli and responses) involving reductionistic, organocentric, and mechanistic metatheory with alternative psychology (means and ends) that is autonomous, contextual, and evolutionary.

Honeybees make decisions collectively--and democratically. Every year, faced with the life-or-death problem of choosing and traveling to a new home, honeybees stake everything on a process that includes collective fact-finding, vigorous debate, and consensus building. In fact, as world-renowned animal behaviorist Thomas Seeley reveals, these incredible insects have much to teach us when it comes to collective wisdom and effective decision making. A remarkable and richly illustrated account of scientific discovery, "Honeybee Democracy" brings together, for the first time, decades of Seeley's pioneering research to tell the amazing story of house hunting and democratic debate among the honeybees.

In the late spring and early summer, as a bee colony becomes overcrowded, a third of the hive stays behind and rears a new queen, while a swarm of thousands departs with the old queen to produce a daughter colony. Seeley describes how these bees evaluate potential nest sites, advertise their discoveries to one another, engage in open deliberation, choose a final site, and navigate together--as a swirling cloud of bees--to their new home. Seeley investigates how evolution has honed the decision-making methods of honeybees over millions of years, and he considers similarities between the ways that bee swarms and primate brains process information. He concludes that what works well for bees can also work well for people: any decision-making group should consist of individuals with shared interests and mutual respect, a leader's influence should be minimized, debate should be relied upon, diverse solutions should be sought, and the majority should be counted on for a dependable resolution.

An impressive exploration of animal behavior, "Honeybee Democracy" shows that decision-making groups, whether honeybee or human, can be smarter than even the smartest individuals in them.

Research into social behaviour in animals has often focused on aggression, yet members of social species are far more likely to interact with each other in a positive way. Animal Friendships explores non-sexual bonding behaviours in a range of mammalian and avian species. Through analysis of factors which trigger and deepen friendships, Dagg uncovers a world of intricate and complex social interactions. These factors include sources of food, formation of coalitions, playdates for infants, mutual grooming and the apparent pleasure of simple companionship. Chapters cover different types of friendship: from those between two individuals, such as male-female or parent-offspring friendships, to those within family groups and even inter-species friendships. Not only does the book explore how and why friendships form, it also showcases the ingenious field techniques used by researchers enabling the reader to understand the scientific methodology. An invaluable read for both researchers and students studying animal social bonding.

The Oxford Animal Biology Series is an innovative new series of supplementary undergraduate texts in comparative animal biology. Topics within each book are addressed using examples from throughout the animal kingdom, looking for parallels that transcend taxonomy. Further reading sections will guide the student into the literature at greater depth. The series will be international in scope, both in terms of the species used as examples and in references to scientific work. Energy for Animal Life, the first book in the series, is about how animals get energy, and how they use it, a central topic in our understanding of animal biology. Life depends on energy, and much of the activity of animals is devoted to getting the food which is their energy source. It encompasses the food chain, from solar radiation and photosynthesis to food sources for herbiviores and for carnivores, and compares the merits of different designs of digestive system, and of different strategies for finding and choosing food. Of course, animal energy isn't simply a question of feeding, and several chapters in turn look at energy use. The energy costs of motion - of running, swimming, and flight - are discussed in one chapter, and the energetic demands of growth and reproduction in another. A chapter on body temperature shows how the processes of life go faster at higher temperatures, and discusses how animals regulate their temperature. A final chapter draws all of these aspects of energy use together, and considers the energy budgets of several different animals, assessing the different energy gains and costs of their everyday activities in the wild. The book is truly comparative, drawing on examples from a wide range of animal species, and lots of practical information on relevant experiments is included. The style is very accessible, and suitable as supplementary reading for first and second year undergraduates taking a degree course in biological sciences.

Birds of paradise have long played a central part in human mythologies and captured the imagination of collectors, scientists, and naturalists. Birds of Paradise provides the first comprehensive, up-to-date, and scientifically accurate overview of the behavior, biology, ecology, biogeography, and history of the most ornate and dramatic group of birds on earth. The book is lavishly illustrated with specially commissioned color depictions of all 42 species of birds of paradise and original line drawings of many behaviors never before recorded, as well as numerous maps and graphs. This stunning book will delight a wide range of readers, from professional ornithologists to amateur naturalists.

This volume brings together the world's leading experts on disgust to fully explore this understudied behavior. Disgust is unique among emotions. It is, at once, perhaps the most "basic" and visceral of feelings while also being profoundly shaped by learning and culture. Evident from the earliest months of life, disgust influences individual behavior and shapes societies across political, social, economic, legal, ecological, and health contexts. As an emotion that evolved to prevent our eating contaminated foods, disgust is now known to motivate wider behaviors, social processes, and customs. On a global scale, disgust finds a place in population health initiatives, from hand hygiene to tobacco warning labels, and may underlie aversions to globalization and other progressive agendas, such as those regarding sustainable consumption and gay marriage. This comprehensive work provides cutting-edge, timely, and succinct theoretical and empirical contributions illustrating the breadth, rigor, relevance, and increasing maturity of disgust research to modern life. It is relevant to a wide range of psychological research and is particularly important to behavior viewed through an evolutionary lens, As such, it will stimulate further research and clinical applications that allow for a broader conceptualization of human behavior. The reader will find: Succinct and accessible summaries of key perspectives Highlights of new scientific developments A rich blend of theoretical and empirical chapters

Males and females often differ in developmental patterns, adult morphology, ecology and behaviour, and in many mammals males are often larger. Size dimorphism results in divergent nutritional and energetic requirements or reproductive strategies by the sexes, which in turn sometimes causes them to select different forage, use different habitats, and express differing social affinities. Such divergent life-styles often lead males and females to live large parts of their lives separately. Sexual segregation is widespread in animals. Males and females may share the same habitat, but at different times, for example, or they might use different habitats entirely. Why did sexual segregation evolve and what factors contribute to it? Sexual Segregation in Vertebrates explores these questions by looking at a wide range of vertebrates and is aimed as a synthesis of our current understanding and a guide for future research.

Behavioural observations from both the field and captivity indicate that same-sex sexual interactions are widespread throughout the animal kingdom, and occur quite frequently in certain non-human species. Proximate studies of these phenomena have yielded important insights into genetic, hormonal and neural correlates. In contrast, there has been a relative paucity of research on the evolutionary aspects. Homosexual Behaviour in Animals is a 2006 text which seeks to redress this imbalance by exploring animal same-sex sexual behaviour from an evolutionary perspective. Contributions focus on animals that routinely engage in homosexual behaviour and include birds, dolphin, deer, bison and cats, as well as monkeys and apes, such as macaques, gorillas and bonobos. A final chapter looks at human primates. This book will appeal to graduate students and researchers in evolutionary biology, biological anthropology, zoology, evolutionary psychology, animal behaviour and anyone interested in the current state of knowledge in this area of behavioural studies.

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.

One of the main tenets of evolutionary biology is that organisms behave so as to maximize the number of their genes that will be passed on to future generations. Parents often produce more offspring than they can rear in case special opportunities or calamities occur. This frequently leads to deprivations and even death of some offspring. This book is about the evolutionary diversity, importance, and consequences of such squeezes. The authors, experts in their field, review the theory, field experiments, and natural history of sibling rivalry across a broad sweep of organisms, in an accessible style that should appeal to both academics and natural historians. This book is intended for graduate students and researchers in evolutionary biology, animal behaviour, ecology, population biology, and in philosophy or social sciences as well as for ornithologists and natural historians.

Humans live in large and extensive societies and spend much of their time interacting socially. Likewise, most other animals also interact socially. Social behaviour is of constant fascination to biologists and psychologists of many disciplines, from behavioural ecology to comparative biology and sociobiology. The two major approaches used to study social behaviour involve either the mechanism of behaviour - where it has come from and how it has evolved, or the function of the behaviour studied. With guest articles from leaders in the field, theoretical foundations along with recent advances are presented to give a truly multidisciplinary overview of social behaviour, for advanced undergraduate and graduate students. Topics include aggression, communication, group living, sexual behaviour and co-operative breeding. With examples ranging from bacteria to social mammals and humans, a variety of research tools are used, including candidate gene approaches, quantitative genetics, neuro-endocrine studies, cost-benefit and phylogenetic analyses and evolutionary game theory.

Why is blood thicker than water'? Are we innately violent or pacific? Why are plants and animals sexual? Why do we grow old and die? Such questions have motivated the life-work of W.D. Hamilton, widely acknowledged as the most important theoretical biologist of the 20th century. His papers continue to exert an enormous influence and they are now being republished for the first time. This first volume contains all of Hamilton's publications prior to 1981, a set especially relevant to social behavior, kinship theory, sociobiology, and the notion of selfish genes'. Each paper is introduced by an autobiographical essay written especially for this collection. Accessible to non-specialists, this fascinating volume features several of the most read and famous papers of modern biology.

Homosexuality is an evolutionary paradox in search for a resolution, not a medical condition in search for a cure. Homosexual behavior is common among social animals, and mainly expressed within the context of a bisexual sexual orientation. Exclusive homosexuality is less common, but not unique to humans. Poiani and Dixson invite the reader to embark on a journey through the evolutionary, biological, psychological and sociological aspects of homosexuality, seeking an understanding of both the proximate and evolutionary causes of homosexual behavior and orientation in humans, other mammals and birds. The authors also provide a synthesis of what we know about homosexuality into a biosocial model that links recent advances in reproductive skew theory and various selection mechanisms to produce a comprehensive framework that will be useful for anyone teaching or planning future research in this field.

The hardback edition of this was the first book on insect flight since J W S Pringle's classic Insect Flight was published in 1957. Much has been written since on applied and ecological aspects of flight, but the question of the origin of wings and flight, their structural concomitants, and the related aerodynamical issues have been confined largely to armchair speculation in a scattered literature. This book is written by a leading authority on insect flight, and for the first time draws a coherent, empirically based picture of how insect flight may have evolved. Following excellent reviews the book is now being made available in paperback.

This detailed 1983 study of the African buffalo is distinguished by the extraordinary first-hand data obtained by the author in ten years of study. During this time, Dr Mloszewski virtually lived with the herds, moving among the animals and becoming accepted by them as a companion in their wanderings. The result is a book written from a highly unusual viewpoint and containing unique data. The book discusses the ancestry, zoological classification, and biogeographical setting of the African buffalo and describes the interactions of buffaloes with other species. The individual and collective behavior of the buffalo in the wild, as directly observed by the author, is the central subject, covering herd movements, feeding activities, hierarchies and individuals and agnostic, reproductive and other behaviors.

An extensively revised third edition of this introduction to neuroethology - the neuronal basis of animal behaviour - for zoology, biology and psychology undergraduate students. The book focuses on the roles of individual nerve cells in behaviour, from simple startle responses to complex behaviours such as route learning by rats and singing by crickets and birds. It begins by examining the relationship between brains and behaviour, and showing how study of specialised behaviours reveals neuronal mechanisms that control behaviour. Information processing by nerve cells is introduced using specific examples, and the establishing roles of neurons in behaviour is described for a predator-prey interaction, toads versus cockroaches. New material includes: vision by insects, which describes sensory filtering; hunting by owls and bats, which describes sensory maps; and rhythmical movements including swimming and flying, which describes how sequences of movements are generated. Includes stunning photographs which capture the detail of the behaviour.

A beautifully written account of the symbiotic relationship between pine trees and jays; a cycle of dependency has progressed for several million years as birds have effectively planted the trees that sustain them by dispersing the seeds. This book covers a wide range of regions, focusing on the Rocky Mountains and the American Southwest, but also ranging from the Alps to Finland, and from Siberia to China. The book is written from the perspectives of evolution, ecology, and animal behaviour.

Animal behaviour, as a discipline, has undergone several key transitions over the last 25 years, growing in both depth and breadth. Key advances have been made in behavioural ecology and socio-biology, in the development of studies integrating proximate and ultimate causation, in the integration of laboratory and field work, and in advances in theoretical work in areas such as sexual selection, foraging and life-history traits. Thus it is appropriate to relate the individual stories of those who have had significant impacts on the field as we know it today. Leaders in Animal Behaviour: The Second Generation is a collection of autobiographies from 21 individuals that have been peer selected, and have provided unique and important contributions to the field in the past 25 years.
