Reproduction is a fundamental feature of life, it is the way life persists across the ages. This book offers new, wider vistas on this fundamental biological phenomenon, exploring how it works through the whole tree of life. It explores facets such as asexual reproduction, parthenogenesis, sex determination and reproductive investment, with a taxonomic coverage extended over all the main groups - animals, plants including 'algae', fungi, protists and bacteria. It collates into one volume perspectives from varied disciplines - including zoology, botany, microbiology, genetics, cell biology, developmental biology, evolutionary biology, animal and plant physiology, and ethology - integrating information into a common language. Crucially, the book aims to identify the commonalties among reproductive phenomena, while demonstrating the diversity even amongst closely related taxa. Its integrated approach makes this a valuable reference book for students and researchers, as well as an effective entry point for deeper study on specific topics.

This is the first book to collate and synthesize the recent burgeoning primary research literature on dog behaviour, evolution, and cognition. The author presents a new ecological approach to the understanding of dog behaviour, demonstrating how dogs can be the subject of rigorous and productive scientific study without the need to confine them to a laboratory environment. This second, fully updated edition of Dog Behaviour, Evolution and Cognition starts with an overview of the conceptual and methodological issues associated with the study of the dog, followed by a brief description of their role in human society. An evolutionary perspective is then introduced with a summary of current research into the process of domestication. The central part of the book is devoted to issues relating to the cognitive aspects of behaviour which have received particular attention in recent years from both psychologists and ethologists. The book's final chapters introduce the reader to many novel approaches to dog behaviour, set in the context of behavioural development and genetics. This second edition recognises and discusses the fact that dogs are increasingly being used as model organisms for studying aspects of human biology, such as genetic diseases and ageing. Specific attention is also given in this edition to attachment behaviour which emerges between humans and dogs, the importance of inter-specific communication in the success of dogs in human communities and the broad aspects of social cognition and how this may contribute to human-dog cooperation Directions for future research are highlighted throughout the text which also incorporates links to human and primate research by drawing on homologies and analogies in both evolution and behaviour. The book will therefore be of relevance and use to anyone with an interest in behavioural ecology including graduate students of animal behaviour and cognition, as well as a more general audience of dog enthusiasts, biologists, psychologists, veterinarians, and sociologists.

'ENCHANTING' MAIL ON SUNDAY They care for their elderly, play with their kids, and always put family first. Can we all learn something from the wisdom of wolves? In this unforgettable book, wolf expert and naturalist Elli Radinger draws on her 25 years of first-hand experience among the wolves of Yellowstone National Park to tell us their remarkable stories. __________ Wolves are more human than we ever knew . . . In fact, they can teach us how to be better humans. They play, love, care for others, show compassion, die of broken hearts, pine for home, work in teams, are endlessly patient and leaders know when to defer to followers. In The Wisdom of Wolves naturalist Elli Radinger takes us on a journey into the heart of the wolf pack, revealing what they can teach us about family, cooperation, survival, leadership, commitment and how to enjoy what life gives us. No other book will bring you closer to discovering the truth about wolves - and ourselves. 'This book is the result of her two decades of close observation; part impassioned memoir, part natural history study, and part photo gallery. Her access to her subjects is extraordinary' SUNDAY TIMES 'Elli's bestselling book suggests that in a high-tech age, when so many of us have become alienated from nature, wolves have much to teach us about the art of living well' DAILY MAIL 'Through The Wisdom of Wolves, we get to feel that little bit closer to the pack and discover what we may have in common' BBC WILDLIFE

It used to be: If you see a coyote, shoot it. Better yet, a bear. Best of all, perhaps? A wolf. How we've gotten from there to here, where such predators are reintroduced,protected, and in some cases revered, is the story Frank Van Nuys tells in Varmints and Victims, a thorough and enlightening look at the evolution of predator management in the American West. As controversies over predator control rage on, Varmints and Victims puts the debate into historical context, tracing the West's relationship with charismatic predators like grizzlies, wolves, and cougars from unquestioned eradication to ambivalent recovery efforts. Van Nuys offers a nuanced and balanced perspective on an often-emotional topic, exploring the intricacies of how and why attitudes toward predators have changed over the years. Focusing primarily on wolves, coyotes, mountain lions, and grizzly bears, he charts the logic and methods of management practiced by ranchers, hunters, and federal officials Broad in scope and rich in detail, this work brings new, much-needed clarity to the complex interweaving of economics, politics, science, and culture in the formulation of ideas about predator species, and in policies directed at these creatures. In the process, we come to see how the story of predator control is in many ways the story of the American West itself, from early attempts to connect the frontier region to mainstream American life and economics to present ideas about the nature and singularity of the region.

Begins with in-depth coverage of wildlife behavior concepts as they relate to conservation problems. Topics will focus principally on discussion, critique, and development of behavioral concepts, with particular attention given to published studies on various topics in wildlife behavioral concepts as related to conservation and natural history. He will include an extensive list of references.

Meet Greg. He's a stocky guy with an outsized swagger. He's been the intimidating, yet sociable don of his posse of friends - including Abe, Keith, Mike, Kevin, and Freddie Fredericks - but one arid summer the tide begins to shift and the third-ranking Kevin starts to get ambitious and seeks a higher position within this social club. But this is no ordinary tale of gangland betrayal - Greg and his entourage are bull elephants in Etosha National Park, Namibia, where, for the last twenty years, Caitlin O'Connell has been a keen observer of their complicated friendships. In Elephant Don, O'Connell, one of the leading experts on elephant communication and social behavior, takes us inside the little-known world of African male elephants, a world that is steeped in ritual, where bonds are maintained by unexpected tenderness punctuated by violence. Elephant Don tracks Greg and his group of bulls as O'Connell tries to understand the vicissitudes of male friendship, power struggles, and play. A frequently heart-wrenching portrayal of commitment, loyalty, and affection between individuals yearning for companionship, it vividly captures the incredible repertoire of elephant behavior and communication. Greg, O'Connell shows, is sometimes a tyrant and other times a benevolent dictator as he attempts to hold on to his position at the top. Though Elephant Don is Greg's story, it is also the story of O'Connell and the challenges and triumphs of field research in environs more hospitable to lions and snakes than scientists. Readers will be drawn into dramatic tales of an elephant society at once exotic and surprisingly familiar, as O'Connell's decades of close research reveal extraordinary discoveries about a male society not wholly unlike our own. Surely we've all known a Greg or two, and through this book we may come to know them in a whole new light.

From foraging patterns in a single tree to social interactions across a home range, how primates use space is a key question in the field of primate behavioral ecology. Drawing on the latest advances in spatial analysis tools, this book offers practical guidance on applying geographic information systems (GIS) to central questions in primatology. An initial methodological section discusses niche modelling, home range analysis and agent-based modelling, with a focus on remote data collection. Research-based chapters demonstrate how ecologists apply this technology to a suite of topics including: calculating the intensity of use of both range and travel routes, assessing the impacts of logging, mining and hunting, and informing conservation strategies.

Each chapter will focus on the known molecular characteristics of specific childhood cancers, focusing on how the molecular 'drivers' can be exploited from a therapeutic standpoint with currently available targeted agents. Where applicable, integration of targeted therapies with conventional cytotoxic agents will be considered. This volume will provide a comprehensive summary of molecular characteristics of childhood cancers, and how the changes involved in transformation provide us with opportunities for developing relatively less toxic, but curative, therapies.

Migration, broadly defined as directional movement to take advantage of spatially distributed resources, is a dramatic behaviour and an important component of many life histories that can contribute to the fundamental structuring of ecosystems. In recent years, our understanding of migration has advanced radically with respect to both new data and conceptual understanding. It is now almost twenty years since publication of the first edition, and an authoritative and up-to-date sequel that provides a taxonomically comprehensive overview of the latest research is therefore timely. The emphasis throughout this advanced textbook is on the definition and description of migratory behaviour, its ecological outcomes for individuals, populations, and communities, and how these outcomes lead to natural selection acting on the behaviour to cause its evolution. It takes a truly integrative approach, showing how comparisons across a diversity of organisms and biological disciplines can illuminate migratory life cycles, their evolution, and the relation of migration to other movements. Migration: The Biology of Life on the Move focuses on migration as a behavioural phenomenon with important ecological consequences for organisms as diverse as aphids, butterflies, birds and whales. It is suitable for senior undergraduate and graduate level students taking courses in behaviour, spatial ecology, 'movement ecology', and conservation. It will also be of interest and use to a broader audience of professional ecologists and behaviourists seeking an authoritative overview of this rapidly expanding field.

This anthology contains 37 articles published since 1974 in American Scientist, the journal of the scientific society Sigma Xi. The richly illustrated articles provide a picture of how behaviourists think about and conduct their research, as well as insights into the behaviour of selected vertebrate and invertebrate species.

In this book, the authors gather and present current research in the study of the behaviour, classification and diseases relating to the feline species. Topics discussed in this compilation include the use of Type 1 interferon for treating feline retrovirosis; new advances in the diagnosis, epizootiology and taxonomy of feline piroplasmids; feline hepatozoonosis and the resurrection of hepatozoon felis; the role of cats in toxoplasma gondii infection; and the therapeutic effect of melatonin in feline uveitis.

Wolves are charismatic emblems of wilderness. Dogs, which descended from wolves, are models of urbanity. Do free-ranging dogs revert to pack living or are their societies only reminiscent of a wolfish heritage? Focusing on behavioral ecology, this is the first book to assess societies of both gray wolves and domestic dogs living as urban strays and in the feral state. It provides a comprehensive review of wolf genetics, particularly of New World wolves and their mixture of wolf, coyote and dog genomes. Spotte draws on the latest scientific findings across the specialized fields of genetics, sensory biology, reproductive physiology, space use, foraging ecology and socialization. This interdisciplinary approach provides a solid foundation for a startling and original comparison of the social lives of wolves and free-ranging dogs. Supplementary material, including a full glossary of terms, is available online at www.cambridge.org/9781107015197.

In every domain of reasoning-from time and space, to mental states and physical illness-humans deploy an exceedingly diverse range of intuitive 'theories' about how the world works. Children from diverse cultures always seem to arrive at a few, common folk theories as they hone their developing brains against roughly similar interactions with people and objects. The result is an impressive panoply of folk notions that the human species uses to explain, predict, and just plain talk about everything from why the sky is blue, to why we catch a cold when we stand out in the rain. Unquestionably, all of this "higher-order" reasoning rests upon a diverse and complex tool-kit of "lower-order" neural and bodily mechanisms, much of which humans share in common with other species (and which, collectively, are quite clever in their right). But this book asks a different question: Are humans alone in trying to make sense of the world by postulating theoretical entities to explain how the world works? Povinelli and his colleagues approach this highly controversial territory by investigating the seemingly prosaic topic whether chimpanzees wield roughly the same commonsense ideas about weight that human do. When it comes to the physical world, they ask if chimpanzees reinterpret a broad range of primary experiences-lifting objects, seeing objects fall or collide, observing the differential effort others exert when they move objects-in terms of a common, causal mechanism which, in our everyday parlance, we refer to as 'weight.' The question is not whether chimpanzees have a theory about weight that's any better or worse than preschool children or Einstein or modern string theorists. The question is whether chimpanzees have any theories at all. And the answer comes in the form of over 30 never-before-published experiments from a decade-long research project involving seven adult chimpanzees and one hundred and twenty preschool children. Povinelli's work encourages us to stand back and adopt a different perspective on even our closest living relatives. Rather than seeing chimpanzees as watered-down versions of ourselves, this book challenges us to see our joint encounter for what it is: a meeting of alien minds.

This Primer nurtures the development of biologists interested in using animal behaviour concepts and tools to solve conservation and wildlife management problems. This is the first practical guide fostering integration and showing how to apply these methodologies to issues that would benefit from an animal behaviour perspective.

Understanding the chimpanzee mind is akin to opening a window onto human consciousness. Many of our complex cognitive processes have origins that can be seen in the way that chimpanzees think, learn, and behave. "The Mind of the Chimpanzee" brings together scores of prominent scientists from around the world to share the most recent research into what goes on inside the mind of our closest living relative.

Intertwining a range of topics--including imitation, tool use, face recognition, culture, cooperation, and reconciliation--with critical commentaries on conservation and welfare, the collection aims to understand how chimpanzees learn, think, and feel, so that researchers can not only gain insight into the origins of human cognition, but also crystallize collective efforts to protect wild chimpanzee populations and ensure appropriate care in captive settings. With a breadth of material on cognition and culture from the lab and the field, "The Mind of the Chimpanzee "is a first-rate synthesis of contemporary studies of these fascinating mammals that will appeal to all those interested in animal minds and what we can learn from them.

Oscar Wilde deemed his life "perfect," and described him as a man with "a soul of that beautiful white Christ which seems coming out of Russia." He is PETER ALEXEYEVICH KROPOTKIN (1842-1921), communist advocate and "anarchist prince." Mutual Aid: A Factor of Evolution, first published in 1902, is his best known book. Written as a series of essays for a British literary journal, this intriguing work filters concepts of evolution through Kropotkin's appreciation for altruism and anarchy, positing cooperation not merely as a beneficial political concept but as an approach that has been-and will continue to be-vital to the long-term survival of humanity. Kropotkin explores "mutual aid" among "animals," "savages," "barbarians," and in the medieval and modern world, and also discusses nesting associations, checks to overmultiplication, adaptations to avoid competition, the origin of the family, the origin of the guilds, and other related issues. Anyone interested in the science of evolution and its influence on the shape of human societies will find this a fascinated read.

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.

With heart-shaped face, buff back and wings, and pure white underparts, the barn owl is a distinctive and much-loved bird which has fascinated people from many cultures throughout history. How did the barn owl colonise the world? What adaptations have made this bird so successful? How is the increasing impact of human disturbance affecting these animals? Answering these questions and more, Roulin brings together the main global perspectives on the evolution, ecology and behaviour of the barn owl and its relatives, discussing topics such as the high reproductive potential, physiology, social and family interaction, pronounced colour variation and global distribution. Accessible and beautifully illustrated, this definitive volume on the barn owl is for researchers, professionals and graduate students in ornithology, animal behaviour, ecology, conservation biology and evolutionary biology, and will also appeal to amateur ornithologists and nature lovers.

Social network analysis is used widely in the social sciences to study interactions among people, groups, and organizations, yet until now there has been no book that shows behavioral biologists how to apply it to their work on animal populations. "Exploring Animal Social Networks" provides a practical guide for researchers, undergraduates, and graduate students in ecology, evolutionary biology, animal behavior, and zoology.

Existing methods for studying animal social structure focus either on one animal and its interactions or on the average properties of a whole population. This book enables researchers to probe animal social structure at all levels, from the individual to the population. No prior knowledge of network theory is assumed. The authors give a step-by-step introduction to the different procedures and offer ideas for designing studies, collecting data, and interpreting results. They examine some of today's most sophisticated statistical tools for social network analysis and show how they can be used to study social interactions in animals, including cetaceans, ungulates, primates, insects, and fish. Drawing from an array of techniques, the authors explore how network structures influence individual behavior and how this in turn influences, and is influenced by, behavior at the population level. Throughout, the authors use two software packages--UCINET and NETDRAW--to illustrate how these powerful analytical tools can be applied to different animal social organizations.

This book explores the strikingly similar ways in which information is encoded in nonverbal man-made signals (e.g., traffic lights and tornado sirens) and animal-evolved signals (e.g., color patterns and vocalizations). The book also considers some coding principles for reducing certain unwanted redundancies and explains how desirable redundancies enhance communication reliability.

Jack Hailman believes this work pioneers several aspects of analyzing human and animal communication. The book is the first to survey man-made signals as a class. It is also the first to compare such human-devised systems with signaling in animals by showing the highly similar ways in which the two encode information. A third innovation is generalizing principles of quantitative information theory to apply to a broad range of signaling systems. Finally, another first is distinguishing among types of redundancy and their separation into unwanted and desirable categories.

This remarkably novel book will be of interest to a wide readership. Appealing not only to specialists in semiotics, animal behavior, psychology, and allied fields but also to general readers, it serves as an introduction to animal signaling and to an important class of human communication.

In creatures as different as crickets and scorpions, mole rats and elephants, there exists an overlooked channel of communication: signals transmitted as vibrations through a solid substrate. Peggy Hill summarizes a generation of groundbreaking work by scientists around the world on this long understudied form of animal communication.

Beginning in the 1970s, Hill explains, powerful computers and listening devices allowed scientists to record and interpret vibrational signals. Whether the medium is the sunbaked savannah or the stem of a plant, vibrations can be passed along from an animal to a potential mate, or intercepted by a predator on the prowl. Vibration appears to be an ancient means of communication, widespread in both invertebrate and vertebrate taxa. Hill synthesizes in this book a flowering of research, field studies documenting vibrational signals in the wild, and the laboratory experiments that answered such questions as what adaptations allowed animals to send and receive signals, how they use signals in different contexts, and how vibration as a channel might have evolved.

"Vibrational Communication in Animals" promises to become a foundational text for the next generation of researchers putting an ear to the ground.

The natural world is filled with diverse - not to mention quirky and odd - animal behaviors. Consider the male praying mantis that continues to mate after being beheaded; the spiders, insects, and birds that offer gifts of food in return for sex; the male hip-pocket frog that carries his own tadpoles; the baby spiders that dine on their mother; the beetle that craves excrement; or the starfish that sheds an arm or two to escape a predator's graps. "Headless Males Make Great Lovers and Other Unusual Natural Histories" celebrates this extraordinary world of animals with essays on curious creatures and their amazing behaviors. Marty Crump - a tropical field biologist well known for her work with the reproductive behavior of amphibians - examines here the bizarre conduct of animals as they mate, parent, feed, defend themselves, and communicate. Crump's enthusiasm for the unusual behaviors she describes - from sex change and free love in sponges to aphrodisiac concoction in bats - is visible on every page, thanks to her skilled storytelling. Steeped in biology, "Headless Males Make Great Lovers" points out that diverse and unrelated animals often share seemingly bizarre behaviors - evidence, Crump argues, that these natural histories, though outwardly weird, are successful ways of living. Illustrated throughout, "Headless Males Make Great Lovers" will enchant the general reader with its tales of blood-squirting horned lizards and intestine-ejecting sea cucumbers - all in the service of a greater appreciation of the diversity of the natural histories of animals.

Sibling rivalry and intergenerational conflict are not limited to human beings. Among seals and piglets, storks and burying beetles, in bird nests and beehives, from apples to humans, family conflicts can be deadly serious, determining who will survive and who will perish. When offspring compete for scarce resources, sibling rivalry kicks in automatically. Parents sometime play favorites or even kill their young. In More than Kin and Less than Kind, Douglas Mock tells us what scientists have discovered about this disturbing side of family dynamics in the natural world. Natural selection operates primarily for the benefit of individuals (and their genes). Thus a family member may profit directly, by producing its own offspring, or indirectly, by helping close kin to reproduce. Much of the biology of family behavior rests on a simple mathematical relationship called Hamilton's rule, which links the benefits and costs of seemingly altruistic or selfish behavior to the degree of relatedness between individuals. Blending natural history and theoretical biology, Mock shows how Hamilton's rule illuminates the study of family strife by throwing a spotlight on the two powerful forces-cooperation and competition-that shape all interaction in the family arena. In More than Kin and Less than Kind, he offers a rare perspective on the family as testing ground for the evolutionary limits of selfishness. When budgets are tight, close kin are often deadly rivals.
