All animals feed selectively. This book examines the selectivity of feeding from a variety of viewpoints. It examines the viewpoint of the behavioural ecologist that considers decision rules, the dietitian that looks at nutritional problems, and the community ecologist that sees feeding as a factor influencing species diversity. The text brings these diverse disciplines together to produce a coherent view of the way in which organisms 'choose' their diet.

Optimal foraging theory has brought the study of foraging behaviour, particularly diet selection to a point where physiological, nutritional, psychological, morphological and ecological factors can begin to be addressed in a coherent fashion. This book is not another exposition of optimal foraging theory, but it does draw on the applications and limitations of the theory to demonstrate the great potential for the development of diet selection as an interdisciplinary subject.
Authoritative synthesis of the latest thinking in optimal foraging and feeding theory.
Adopts, for the first time, a truly interdisciplinary approach to diet selection.
Authored by experts from each of the contributing fields.

Celebratory, joyous and moving, this is a book about the profoundly healing, curative qualities of dogs - and how we need dogs in our lives more than ever. The dog-human bond is the most extraordinary cross-species friendship on the planet. Dogs give people so much: affection, companionship and profound emotional support. Now, more than ever, we can see the clear health benefits of living with a dog by our side. Drawing on science, research and in-depth personal interviews, Good Dog demonstrates how vastly a dog can improve our mental and physical health as well as our quality of life. Kate Leaver begins by telling the story of how she met her beloved rescue shih tzu, Bertie, and how powerfully he helps her through periods of depression. Then she meets 10 other remarkable dogs who've changed human lives - from Missy the pug, who helps 11-year-old Cody live his best life despite his autism diagnosis, to Pip, who helps her teenage owner manage diabetes, and Jingles, who works with inmates in a prison. With each story, it becomes more and more obvious how profoundly dogs can support us, comfort us and even save our lives. Celebratory, joyous and moving, this is a book for anyone who has ever loved a dog - and known their love in return.

In "What Animals Teach Us about Politics," Brian Massumi takes up the question of "the animal." By treating the human as animal, he develops a concept of an animal politics. His is not a human politics of the animal, but an integrally animal politics, freed from connotations of the "primitive" state of nature and the accompanying presuppositions about instinct permeating modern thought. Massumi integrates notions marginalized by the dominant currents in evolutionary biology, animal behavior, and philosophy--notions such as play, sympathy, and creativity--into the concept of nature. As he does so, his inquiry necessarily expands, encompassing not only animal behavior but also animal thought and its distance from, or proximity to, those capacities over which human animals claim a monopoly: language and reflexive consciousness. For Massumi, humans and animals exist on a continuum. Understanding that continuum, while accounting for difference, requires a new logic of "mutual inclusion." Massumi finds the conceptual resources for this logic in the work of thinkers including Gregory Bateson, Henri Bergson, Gilbert Simondon, and Raymond Ruyer. This concise book intervenes in Deleuze studies, posthumanism, and animal studies, as well as areas of study as wide-ranging as affect theory, aesthetics, embodied cognition, political theory, process philosophy, the theory of play, and the thought of Alfred North Whitehead.

Drawing on expertise from around the world, this volume identifies our current state of knowledge about the behavior and physiology of root herbivores. In particular, this work describes prevailing concepts and theories based on historical and current literature and identifies what new technologies and approaches are available to researchers in the field. Chapters address how root herbivore behavior and physiology is affected by the biotic and abiotic soil environment, cover case studies of globally significant pests and discuss advances in molecular techniques. Covering all aspects of behavioral and physiological responses of root herbivores to their environment, this will be valuable reading for researchers and professionals in agricultural entomology, plant science, ecology and soil science.

Key topics include: Molecular approach to root herbivoresPhylloxeraPlant metabolitesSoil climateBehavioral ecology / wireworms

This book presents topical research on human and animal mating strategies, gender differences and environmental influences. Topics include the mating effects on female reproductive organs and the paradigm of oestrogen signalling pathways in the oviduct; sexual maturation, mating strategies and neuroendocrinology in social insects; plasticity in mating patterns of a benthic nest-holding fish related to the effects of nest-site abundance and social interactions; and human sexual strategies of short-term mating and parental control over mate choice.

"Rational Animals: The Teleological Roots of Intentionality" offers an original account of the intentionality of human mental states, such as beliefs and desires.
The account of intentionality in "Rational Animals" is broadly biological in its basis, emphasizing the continuity between human intentionality and the levels of intentionality that should be attributed to animal actions and states.
Establishing the goal-directed character of animal behavior, Mark Okrent argues that instrumentally rational action is a species of goal-directed behavior that is idiosyncratic to individual agents and is distinguished by its novelty and flexibility. He also argues that some nonlinguistic animals are capable of instrumental rationality and that in the first instance, the contents of beliefs and desires are individuated by the explanatory role of those states in rationally accounting for such instrumentally rational behavior.
The account of instrumental rationality offered in Rational Animals allows for understanding the practical rationality of linguistically competent human beings as a distinctive capacity of social animals capable of undertaking roles governed by socially sanctioned norms.
Rational Animals will be of interest to cognitive scientists, philosophers of mind, philosophers of biology, philosophers of action, ethologists, and those interested in the debates concerning animal intelligence.

In more ways than we may sometimes care to acknowledge, the human being is just another primate--it is certainly only very rarely that researchers into cognition, emotion, personality, and behavior in our species and in other primates come together to compare notes and share insights. This book, one of the few comprehensive attempts at integrating behavioral research into human and nonhuman primates, does precisely that--and in doing so, offers a clear, in-depth look at the mutually enlightening work being done in psychology and primatology.

Relying on theories of behavior derived from psychology rather than ecology or biological anthropology, the authors, internationally known experts in primatology and psychology, focus primarily on social processes in areas including aggression, conflict resolution, sexuality, attachment, parenting, social development and affiliation, cognitive development, social cognition, personality, emotions, vocal and nonvocal communication, cognitive neuroscience, and psychopathology. They show nonhuman primates to be far more complex, cognitively and emotionally, than was once supposed, with provocative implications for our understanding of supposedly unique human characteristics. Arguing that both human and nonhuman primates are distinctive for their wide range of context-sensitive behaviors, their work makes a powerful case for the future integration of human and primate behavioral research.

Seeing a cat rubbing against a person, Charles Darwin described her as \u0022in an affectionate frame of mind\u0022; for Samuel Barnett, a behavioralist, the mental realm is beyond the grasp of scientists andbehavior must be described technically, as a physical action only. What difference does this difference make? In Eileen Crist's analysis of the language used to portray animal behavior, the difference \u0022is that in the reader's mind the very image of the cat's 'body' is transfigured...from an experiencing subject...into a vacant object.\u0022 Images of Animals examines the literature of behavioral science, revealing how works with the common aim of documenting animal lives, habits, and instincts describe \u0022realities that are worlds apart.\u0022 Whether the writer affirms the Cartesian verdict of an unbridgeable chasm between animals and humans or the Darwinian panorama of evolutionary continuity, the question of animal mind is ever present and problematic in behavioral thought. Comparing the naturalist writings of Charles Darwin, Jean Henri Fabre, and George and Elizabeth Peckham to works of classical ethology by Konrad Lorenz and Nikolaas Tinbergen and of contemporary sociobiology, Crist demonstrates how words matter. She does not attempt to defend any of these constructions as a faithful representation of animal existence, but to show how each internally coherent view molds the reader's understanding of animals. Rejecting the notion that \u0022a neutral language exists, or can be constructed, which yields incontestably objective accounts of animal behavior,\u0022 Crist argues that \u0022language is not instrumental in the depiction of animals and, in particular, it is never impartial with respect to the question of animal mind.\u0022

This text presents the results of a research project carried out on foraging behaviour among African baboons and its consequences for survival and reproduction. Detailed data is provided on the feeding habits of each baboon, with an analysis of its nutrient intake. These figures are then compared with those in optimum diets. The most striking result of this study is that the baboon's subsequent survival and reproductive success could be accurately predicted from what they had eaten as yearlings. The animals with energy intakes closest to the optimum and protein intakes furthest above their requirements were most likely to survive to adulthood and to successfully produce offspring.

This unique volume of thirty essays, by fifty-three internationally known scholars, honours C.S. (Rufus) Churcher, the distinguished Canadian palaeontologist. The papers focus on late Cenozoic mammals in North America and Africa and provide both site-specific descriptions of faunas and their associated geological contexts, and more general syntheses of regional palaeoenvironments and biogeography. The volume provides a much-needed overview of current research. The stature of the researchers who have contributed to the volume, and the breadth of the material presented, is a reflection of Churcher’s diverse research interests. The first section contains eleven papers on the palaeoenvironment and palaeoecology of Quaternary mammals in North America; the second section has 9 contributions describing faunas and morphological analyses of North American Quaternary mammals; and the final section contains nine papers on the palaeoecology and palaeoenvironments of late Cenozoic mammals of Africa. In this final section, Alan Gentry pays tribute to Churcher by naming a species after him: Budorcas churcheri. The volume contains individual discussions of North American fossil prairie dogs, mastodons, zebras, short-faced bears, sabre cats, lions, giant armadillos, elk-moose, caribou and muskrats, as well as African hyaenas, zebras, hipparion horses, antelopes, rodents, and giraffes.

Do chimpanzees have something akin to culture? Bringing together studies of behavioral variation within and among chimpanzees and bonobos --the sibling species of the genus "Pan"--this book provides the basis for answering this question. In "Chimpanzee Cultures," the world's leading authorities on chimpanzees and bonobos chronicle the animals' behaviors from one study site to the next, in both captive and wild groups, in laboratory and field settings.

To observe a dog's guilty look. to witness a gorilla's self-sacrifice for a wounded mate, to watch an elephant herd's communal effort on behalf of a stranded calf--to catch animals in certain acts is to wonder what moves them. Might there he a code of ethics in the animal kingdom? Must an animal be human to he humane? In this provocative book, a renowned scientist takes on those who have declared ethics uniquely human Making a compelling case for a morality grounded in biology, he shows how ethical behavior is as much a matter of evolution as any other trait, in humans and animals alike. World famous for his brilliant descriptions of Machiavellian power plays among chimpanzees-the nastier side of animal life--Frans de Waal here contends that animals have a nice side as well. Making his case through vivid anecdotes drawn from his work with apes and monkeys and holstered by the intriguing, voluminous data from his and others' ongoing research, de Waal shows us that many of the building blocks of morality are natural: they can he observed in other animals. Through his eyes, we see how not just primates but all kinds of animals, from marine mammals to dogs, respond to social rules, help each other, share food, resolve conflict to mutual satisfaction, even develop a crude sense of justice and fairness. Natural selection may be harsh, but it has produced highly successful species that survive through cooperation and mutual assistance. De Waal identifies this paradox as the key to an evolutionary account of morality, and demonstrates that human morality could never have developed without the foundation of fellow feeling our species shares with other animals. As his work makes clear, a morality grounded in biology leads to an entirely different conception of what it means to he human--and humane.

This is a critical survey of the physiological approach to learning, memory and intelligence in animals. Emphasis has been placed on the implications of physiological research for theories of the intelligence processes of animals.

Mammalian Dispersal Patterns examines the ways that social structure affects population genetics and, in turn, rates of evolution, in mammalian groups. It brings together fieldwork in animal behavior and wildlife biology with theoretical work in demography and population genetics. The focus here is dispersal--whether, how, and when individuals leave the areas where they are born.
Theoretical work in population genetics indicates that such social factors as skewed sex ratios, restrictive mating patterns, and delayed age of first reproduction will lower the reproductive variability of a population by reducing the number of genotypes passed from one generation to the next. Field studies have shown that many mammalian species do exhibit many such social characteristics. Among horses, elephant seals, and a number of primates, the majority of females are inseminated by only a fraction of the males. In pacts of wolves and mongooses, usually only the highest-ranking male and female breed in a given season. Although socially restricted mating tends to lower genetic variability in isolated populations, it actually tends to increase genetic variability in subdivided populations with low rates of migration between subunits. Among some species there is little dispersal and thus little gene flow between subpopulations; other species travel far afield before mating.
The contributors to this volume examine actual data from populations of mammals, the way patterns of dispersal correlate with the genetic structure of individuals and populations, and mathematical models of population structure. This interdisciplinary approach has an important bearing on work in conservation of both wildlife and zoo populations, for it shows that the home range and the population size needed to maintain genetic variability can differ greatly from one species to the next. The volume also offers a fruitful model for future research.

This fully-revised new edition of the best-selling Equine Clinical Medicine, Surgery and Reproduction is supported by over 1800 illustrations of the highest quality: colour photographs, diagnostic images including MRI and CT, and diagrams. System-based, the chapters introduce each individual system with precise information on the relevant basic anatomy and physiology, standard clinical examination techniques and useful differential diagnostic aids. This is followed by diseases and disorders that are pertinent to that system, grouped together either anatomically or based on presenting clinical signs. Each condition is described using consistent headings: definition/overview, etiology and pathophysiology, clinical presentation, diagnosis, differential diagnoses, management/treatment, and prognosis. Additional chapters deal with the foal and wounds. New to the second edition: - All chapters are updated throughout - Additional chapters on the axial musculoskeletal system (neck, back and pelvis) and muscle diseases and problems - A whole new section on soft tissue injuries of the foot - More information on diagnostic tests including over-ground endoscopy, chest and liver ultrasonography, head CT, and foot MRI - Material on equine dentistry, neurology, endocrine system, the foal, and the liver has been considerably expanded - All illustrations and photographs have been reviewed and many replaced with higher quality images. The focus throughout remains on providing clinically relevant information required for practical case management, plus sufficient background on causes and disease processes to enable readers to understand the conditions and the rationale for diagnostic and treatment options. An international group of respected clinicians have come together under the editorship of Dr Graham Munroe to create a textbook that will be of lasting value as a teaching and training resource for equine clinical teachers and their students in veterinary medicine and related equine courses, as well as a ready reference for non-specialist mixed or equine clinical practitioners

Pleasurable Kingdom marshalls the latest evidence that animals, like humans, enjoy themselves. It debunks the popular perception that life for most is a continuous, grim struggle for survival. Instead it suggests that creatures from birds to bats to baboons may feel good thanks to play, sex, touch, food, anticipation, comfort, aesthetics and more. Combining rigorous evidence, elegant argument and amusing anecdote, leading animal behaviour researcher Dr Jonathan Balcombe proposes that evolution favours sensory rewards because they drive living things to stay alive and reproduce. Animal pain and stress, once controversial, are now acknowledged by legislation in many countries. Likewise the possibility of positive feelings in creatures other than humans has important ramifications for science and society and is thus ripe for informed debate, Balcombe concludes.

This book presents the discoveries made during nearly three decades of research on the parental shield bug, Parastrachia japonensis inhabiting Kyushu Island, Japan. P. japonensis has evolved a unique and fascinating life history, characterized by extreme behavioral and physiological adaptations that have culminated in a singularly dependent relationship with its lone host tree, Schoepfia jasminodora (Olacaceae), which is a generally scarce and unreliable resource. It is expected that the evolution of parental care behaviors in the strictly semelparous P. japonensis was more directly influenced by the benefit to females that arises from enhanced survivorship of current offspring, rather than any possible cost the females might incur in terms of reduced future reproductive success, because no future reproduction is possible. The authors explain how the different parental cares in this species enhance offspring survivorship in the context of the ecological conditions it has experienced over evolutionary time. The book begins with a recap of the earliest studies, the reports through 1991, and then introduces the many fascinating aspects of the life history, neurobiology, physiology and behavior of P. japonensis that have been newly discovered since, and those aspects that have been confirmed through experimentation over the past thirty years. This comprehensive review of information will be useful for comparative studies of parental care in other semelparous and iteroparous organisms experiencing both similar and different ecological constraints. The book will be of academic interest to undergraduate and graduate students of entomology, zoology, behavior, and behavioral ecology.

Unsere Sinne - Sehen, Hoeren, Riechen, Schmecken und Tasten - bestimmen wesentlich unser Leben. Alles was wir wissen, wurde uns von unseren Sinnen vermittelt. Aber wie funktionieren unsere Sinne und wie kommt das Wissen uber die Welt in unseren Kopf? Nach welchen Kriterien entscheidet unser Gehirn, was zu tun ist? In diesem Sachbuch wird allgemeinverstandlich dargelegt, wie hoch entwickelt die Sinnesorgane bei Tieren und Menschen sind. Oft erreichen Sinnesleistungen die Grenze des physikalisch Moeglichen. Das Buch erklart, wie Sinnesreize erfasst werden, wie sie in die Sprache des Nervensystems ubersetzt werden und wie unser Gehirn Sinnesinformation verarbeitet. Das Gehirn setzt dabei auf wohl bewahrte Strategien, die ein Ziel verfolgen: die UEberlebenschance des Organismus zu erhoehen. Deshalb wird in diesem Buch gezeigt, wie sehr die Sinnesleistungen durch die Evolution geformt und bestimmt wurden. Das Buch zeigt auch, dass viele Tiere ihre Umwelt vollkommen anders wahrnehmen als wir. Fur die Neuauflage haben die Autoren den Text durchgesehen und auf den aktuellen Stand gebracht.

Despite their diversity, amphibians and reptiles share many physiological traits, such as their dependence on external heat sources for body temperature regulation, that are of pivotal importance to their ability to cope with the environment. Considerable variation in physiological capabilities exists in these groups and often can be related to seasonal and geographic differences in environmental parameters. This book provides a comprehensive and integrative view of the interplay between physiology and behavior in amphibians and reptiles, leading to a better understanding of the subject. The book covers topics that have recently been in the spotlight for scientific research on the physiology, behavior, and conservation of amphibians and reptiles. It brings together recent information from a range of disciplines that address critical topics for understanding their biology. As these studies are scattered across articles in specialized journals, this book provides a single and expanded source summarizing such advancements. Amphibian and Reptile Adaptations to the Environment: Interplay Between Physiology and Behavior maintains a solid scientific basis for the biological topics covered. However, it presents the material in a clear and direct manner so that it is accessible even to non-biologists interested in the basic biology, behavior, and ecology of these animals as well as how these elements are connected to their conservation.

Can the structures that animals build--from the humble burrows of earthworms to towering termite mounds to the Great Barrier Reef--be said to live? However counterintuitive the idea might first seem, physiological ecologist Scott Turner demonstrates in this book that many animals construct and use structures to harness and control the flow of energy from their environment to their own advantage. Building on Richard Dawkins's classic, "The Extended Phenotype," Turner shows why drawing the boundary of an organism's physiology at the skin of the animal is arbitrary. Since the structures animals build undoubtedly do physiological work, capturing and channeling chemical and physical energy, Turner argues that such structures are more properly regarded not as frozen behaviors but as external organs of physiology and even extensions of the animal's phenotype. By challenging dearly held assumptions, a fascinating new view of the living world is opened to us, with implications for our understanding of physiology, the environment, and the remarkable structures animals build.

This impressive collection features Richard Herrnstein's most important and original contributions to the social and behavioral sciences--his papers on choice behavior in animals and humans and on his discovery and elucidation of a general principle of choice called the matching law. In recent years, the most popular theory of choice behavior has been rational choice theory. Developed and elaborated by economists over the past hundred years, it claims that individuals make choices in such a way as to maximize their well-being or utility under whatever constraints they face; that is, people make the best of their situations. Rational choice theory holds undisputed sway in economics, and has become an important explanatory framework in political science, sociology, and psychology. Nevertheless, its empirical support is thin. The matching law is perhaps the most important competing explanatory account of choice behavior. It views choice not as a single event or an internal process of the organism but as a rate of observable events over time. It states that instead of maximizing utility, the organism allocates its behavior over various activities in exact proportion to the value derived from each activity. It differs subtly but significantly from rational choice theory in its predictions of how people exert self-control, for example, how they decide whether to forgo immediate pleasures for larger but delayed rewards. It provides, through the primrose path hypothesis, a powerful explanation of alcohol and narcotic addiction. It can also be used to explain biological phenomena, such as genetic selection and foraging behavior, as well as economic decision making.
