This book brings together international experts to examine interactions between the biology of wildlife and the divergent goals of people involved in hunting, fishing, gathering, and culling wildlife. Reviews of theory show how sustainable exploitation is tied to the study of population dynamics, with direct links to reproductive rates, life histories, behavior, and ecology. As such theory is rarely put into practice to achieve sustainable use and effective conservation, Conservation of Exploited Species explores the many reasons for this failure and considers remedies to tackle them.

Parasitology is an immensely important aspect of biological science. This manual presents fifty easy-to-follow laboratory exercises for student practical (lab) classes. All the exercises are tried and tested by the authors and are used in a wide variety of university undergraduate teaching departments. They range from relatively simple observational exercises, using local materials and requiring little in the way of equipment, to more technically demanding experiments in physiology and molecular parasitology. Each exercise includes a list of necessary equipment, consumables and sources of parasite material, instructions for staff and students, including aspects of safety, expected results, and some analysis provided by questions. In addition, the text also includes ideas for further exploration and information on similar exercises, as well as lists of selected further reading. This book should be an essential purchase for all teachers of parasitology at the university undergraduate level and for students taking laboratory practical classes in the subject.

Cats and Conservationists is the first multidisciplinary analysis of the heated debate about free-roaming cats. The debate pits conservationists against cat lovers, who disagree both on the ecological damage caused by the cats and the best way to manage them. An impassioned and spirited conflict, it also sheds light on larger questions about how we interpret science, incorporate diverse perspectives, and balance competing values in order to encourage constructive dialogue on contentious social and environmental issues.On one side of the cat debate stand many environmentalists, especially birders and conservation organizations, who believe that outdoor cats seriously threaten native wildlife. On the other side are many animal welfare advocates, who believe that outdoor cats generally do not pose a major ecological threat and that it is possible for cats and wildlife to coexist. They believe that it is possible, mainly through trap-neuter-return projects (TNR), to keep free-roaming cat populations in check without killing large numbers of cats. Careful analysis suggests that there remain important questions about the science on both cat predation and TNR effectiveness. Yet both sides of the conflict insist that the evidence is clear-cut. This false certainty contributes to conflict between conservationists and cat lovers, and obscures common goals that could generate constructive discussions and collaborative efforts among scientists, policymakers, conservationists, and animal welfare advocates. Cats and Conservationists aims to facilitate such collaboration in order to manage outdoor cats and minimize the damage they cause. It also offers models for constructive debates about the public role of science in other polarized public conflicts over science and environmental topics.

Ladybird beetles are typical predators that feed on a wide range of insect prey, and have been used extensively in the biocontrol of insect pests. This volume explores basic ladybird biology, in particular, their close association with prey and its effect on their rate of development and body size. The author uses optimal foraging theory, field observations, and laboratory experiments to illustrate how ladybird larvae maximize their rate of energy intake, and ladybird adults their fitness. The interdependence of these life history parameters is then used to develop a simple predator-prey model that, combined with an analysis of the literature, highlights the specific attributes of potentially successful biocontrol agents for all those interested in predator-prey dynamics.

The study of animal development has deep historical roots in codifying the field of evolutionary biology. In the 1940s, evolutionary theory became engulfed by microevolutionary genetic analysis and development became focused on mechanisms, forsaking the evolutionary implications of ontogeny. Recently, ontogeny has resurfaced as a significant component of evolutionary change, population, and community dynamics. Ontogeny, Functional Ecology and Evolution of Bats is a unique reference work by bat biologists who emphasize the importance of understanding ontogeny in the analysis of evolution and ecology. In addition, the developmental underpinnings of specialized morphology, physiology, and behavior are elucidated, and the strong influence of ecology on the ontological niche of juvenile bats is illustrated. This book is an essential reference for bat biologists, and all those working in the fields of ecology, developmental biology, evolution, behavior, and systematics.

"Part review, part testament to extraordinary dedication, and part call to get involved, "Cetacean Societies" highlights the achievements of behavioral ecologists inspired by the challenges of cetaceans and committed to the exploration of a new world."--from the preface by Richard Wrangham
Long-lived, slow to reproduce, and often hidden beneath the water's surface, whales and dolphins (cetaceans) have remained elusive subjects for scientific study even though they have fascinated humans for centuries. Until recently, much of what we knew about cetaceans came from commercial sources such as whalers and trainers for dolphin acts. Innovative research methods and persistent efforts, however, have begun to penetrate the depths to reveal tantalizing glimpses of the lives of these mammals in their natural habitats.
"Cetacean Societies" presents the first comprehensive synthesis and review of these new studies. Groups of chapters focus on the history of cetacean behavioral research and methodology; state-of-the-art reviews of information on four of the most-studied species: bottlenose dolphins, killer whales, sperm whales, and humpback whales; and summaries of major topics, including group living, male and female reproductive strategies, communication, and conservation drawn from comparative research on a wide range of species.
Written by some of the world's leading cetacean scientists, this landmark volume will benefit not just students of cetology but also researchers in other areas of behavioral and conservation ecology as well as anyone with a serious interest in the world of whales and dolphins.
Contributors are Robin Baird, Phillip Clapham, Jenny Christal, Richard Connor, Janet Mann, Andrew Read, Randall Reeves, Amy Samuels, Peter Tyack, Linda Weilgart, Hal Whitehead, Randall S. Wells, and Richard Wrangham.

Although the behavior and ecology of primates has been more thoroughly studied than that of any other group of mammals, there have been very few attempts to compare the communities of living primates found in different parts of the world. In Primate Communities, an international group of experts compares the composition, behavior, and ecology of primate communities in Africa, Asia, Madagascar, and South America. They examine the factors underlying the similarities and differences among these communities, including their phylogenetic history, climate, rainfall, soil type, forest composition, competition with other vertebrates, and human activities. As it brings together information about primate communities from around the world for the very first time, it will quickly become an important source book for researchers in anthropology, ecology, and conservation, and a readable and informative text for undergraduate and graduate students studying primate ecology, primate conservation, or primate behavior.

Quaggas were beautiful pony-sized zebras in southern Africa that had fewer stripes on their bodies and legs, and a browner body coloration than other zebras. Indigenous people hunted quaggas, portrayed them in rock art, and told stories about them. Settlers used quaggas to pull wagons and to protect livestock against predators. Taken to Europe, they were admired, exhibited, harnessed to carriages, illustrated by famous artists and written about by scientists. Excessive hunting led to quaggas' extinction in the 1880s but DNA from museum specimens showed rebreeding was feasible and now zebras resembling quaggas live in their former habitats. This rebreeding is compared with other de-extinction and rewilding ventures and its appropriateness discussed against the backdrop of conservation challenges-including those facing other zebras. In an Anthropocene of species extinction, climate change and habitat loss which organisms and habitats should be saved, and should attempts be made to restore extinct species?

This book describes the sampling and statistical methods used most often by behavioral ecologists and field biologists. Written by a biologist and two statisticians, it provides a rigorous discussion together with worked examples of statistical concepts and methods that are generally not covered in introductory courses, and which are consequently poorly understood and applied by field biologists. The first section reviews important issues such as defining the statistical population and the sampling plan when using nonrandom methods for sample selection, bias, interpretation of statistical tests, confidence intervals, and multiple comparisons. After a detailed discussion of sampling methods and multiple regression, subsequent chapters discuss specialized problems such as pseudoreplication, and their solutions. This volume will quickly become the favorite statistical handbook for all field biologists.

Many mammals, such as otters, live in close association with rivers and streams, feeding in them, or using them as a place of safety or means of escape from predators. The distinct adaptations that riparian mammals have evolved in order to live in these environments also handicap them for living elsewhere. These animals are therefore threatened by alterations to their environment. In recent years, our rivers have become highly polluted, and have been subject to bankside modifications for agriculture and forestry, enhanced or decreased water flow, and recreation. As a result, they have become less and less suitable for these highly specialized animals. This book looks at the habitat utilization, adaptation, feeding ecology, and conservation status of a range of riparian mammals. It gives insights into the problems facing these fascinating animals, and how they might be overcome.

At first glance, studying behavior is easy, but as every budding ethologist quickly realizes, there are a host of complex practical, methodological and analytical problems to solve before designing and conducting the study. How do you choose which species or which behavior to study? What equipment will you need to observe and record behavior successfully? How do you record data in the dark, in the wet, or without missing part of the action? How do you analyze and interpret the data to yield meaningful information? This new expanded edition of the Handbook of Ethological Methods provides a complete step-by-step introduction to ethological methods from topic choice and behavioral description to data collection and statistical analysis. This book is a must for both beginning students and experienced researchers studying animal behavior in the field or laboratory.

Aldo Leopold: A Fierce Green Fire (OUP; 1999) remains the only biography for the general public on Leopold. It was praised for being concise and readable, and written in the context of the history of American conservation. In a second edition, Marybeth Lorbiecki has added new chapters on Leopold's legacy-the ripple effects of the ecological knowledge, ethics, and leadership he instilled in his wife's family in the Southwest, his children, graduate students, organizations-and on his relevance today. In a new introduction, Lorbiecki explains why Leopold is still so relevant, focusing on the new ecological challenges we face and the myriad of ways his work influences us today, including phenological studies he started at the Shack and their role in proving climate change, and responses to these challenges based on a land ethic. New chapters focus on the Leopold children and their contributions to the land ethic and ecology in their different scientific fields, Leopold's key graduate students and their contributions to various fields, and the recent activities of various organizations that Leopold helped launch.

Animals as geomorphic agents have primarily been considered "curiosities" in the literature of geomorphology, whose spatial and quantitative influences have been seen as both limited and minor. Zoogeomorphology: Animals as Geomorphic Agents examines the distinct geomorphic influences of invertebrates, ectothermic vertebrates, birds, and mammals, and demonstrates the importance of animals as landscape sculptors. Specific processes associated with the diversity of animal influences in geomorphology are examined, including burrowing and denning, nesting, lithophagy and geophagy, wallowing and trampling, food caching, excavating for food, and dam building by beavers. Particular emphasis is placed on terrestrial animals, although aquatic animals are also discussed where appropriate. This book, which is the only one available wholly devoted to this topic, will interest graduate students and professional research workers in geomorphology, ecology, environmental science, physical geography, and geology.

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.

The "ant" and the "peacock" stand for two puzzles in Darwinism--altruism and sexual selection. How can natural selection favor those, such as the worker ant, that renounce tooth and claw in favor of the public-spirited ways of the commune? And how can "peacocks"--flamboyant, ornamental and apparently useless--be tolerated by the grimly economical Darwinian reaper? Helena Cronin has a deep understanding of today's answers to these riddles and their roots in the nineteenth century; the analysis is new and exciting and the explanations lucid and compelling.

Much as Rachel Carson's "Silent Spring" was a call to action against the pesticides that were devastating bird populations, Charles S. Elton's classic "The Ecology of Invasions by Animals and Plants" sounded an early warning about an environmental catastrophe that has become all too familiar today--the invasion of nonnative species. From kudzu to zebra mussels to Asian long-horned beetles, nonnative species are colonizing new habitats around the world at an alarming rate thanks to accidental and intentional human intervention. One of the leading causes of extinctions of native animals and plants, invasive species also wreak severe economic havoc, causing $79 billion worth of damage in the United States alone.
Elton explains the devastating effects that invasive species can have on local ecosystems in clear, concise language and with numerous examples. The first book on invasion biology, and still the most cited, Elton's masterpiece provides an accessible, engaging introduction to one of the most important environmental crises of our time.
Charles S. Elton was one of the founders of ecology, who also established and led Oxford University's Bureau of Animal Population. His work has influenced generations of ecologists and zoologists, and his publications remain central to the literature in modern biology.
"History has caught up with Charles Elton's foresight, and "The Ecology of Invasions" can now be seen as one of the central scientific books of our century."--David Quammen, from the Foreword to "Killer Algae: The True Tale of a Biological Invasion"

Does biodiversity influence how ecosystems function? Might diversity loss affect the ability of ecosystems to deliver services of benefit to humankind? Ecosystems provide food, fuel, fiber, and drinkable water, regulate local and regional climate, and recycle needed nutrients, among other things. An ecosyste's ability to sustain functioning may depend on the number of species residing in the ecosystem--its biological diversity--but this has been a controversial hypothesis. There are many unanswered questions about how and why changes in biodiversity could alter ecosystem functioning. This volume, written by top researchers, synthesizes empirical studies on the relationship between biodiversity and ecosystem functioning and extends that knowledge using a novel and coordinated set of models and theoretical approaches.

These experimental and theoretical analyses demonstrate that functioning usually increases with biodiversity, but also reveals when and under what circumstances other relationships between biodiversity and ecosystem functioning might occur. It also accounts for apparent changes in diversity-functioning relationships that emerge over time in disturbed ecosystems, thereby addressing a major controversy in the field. The volume concludes with a blueprint for moving beyond small-scale studies to regional ones--a move of enormous significance for policy and conservation but one that will entail tackling some of the most fundamental challenges in ecology.

This book focuses on the design and analysis of ecological experiments, concentrating on statistical approaches. Each chapter presents a particular statistical technique or set of techniques in the context of resolving an ecological issue. This new edition eliminates some topics that havein become less important to ecology, adds new chapters on thehe major developing issues, (power analysis, logisticecome less regression, randomization tests, and empiral Baynesian analysis), and updates all the presentations.

Nearly half the world's primate species use flooded habitats at one time or another, from swamp-going Congo gorillas and mangrove-eating proboscis monkeys, to uacaris in Amazonian riverside forests. This first-ever volume on the subject brings together experts from around the world in a ground breaking volume spanning fossil history, current biology and future research and conservation priorities. Flooded habitats are a vital part of tropical biology, both for the diversity of the species they house, and the complexity of their ecological interactions, but are often completely overlooked. This book will set the stage for a new wave of research on primates in these extraordinarily productive and highly threatened areas, and is ideal for researchers and graduate students in primatology, zoology, ecology, and conservation.

"Spatial Ecology" addresses the fundamental effects of space on the dynamics of individual species and on the structure, dynamics, diversity, and stability of multispecies communities. Although the ecological world is unavoidably spatial, there have been few attempts to determine how explicit considerations of space may alter the predictions of ecological models, or what insights it may give into the causes of broad-scale ecological patterns. As this book demonstrates, the spatial structure of a habitat can fundamentally alter both the qualitative and quantitative dynamics and outcomes of ecological processes.

"Spatial Ecology" highlights the importance of space to five topical areas: stability, patterns of diversity, invasions, coexistence, and pattern generation. It illustrates both the diversity of approaches used to study spatial ecology and the underlying similarities of these approaches. Over twenty contributors address issues ranging from the persistence of endangered species, to the maintenance of biodiversity, to the dynamics of hosts and their parasitoids, to disease dynamics, multispecies competition, population genetics, and fundamental processes relevant to all these cases. There have been many recent advances in our understanding of the influence of spatially explicit processes on individual species and on multispecies communities. This book synthesizes these advances, shows the limitations of traditional, non-spatial approaches, and offers a variety of new approaches to spatial ecology that should stimulate ecological research.

Wildlife and the countryside are highly valued by people in the UK, and for good reason. Healthy habitats are invaluable assets and promote human wellbeing. However, they are under increasing threat from, among other things, relentless urban expansion and intensive modern agriculture. These pressures largely stem from a major underlying cause - the high and growing population of humans living in the UK. This book provides an overview of wildlife in the UK and its recent status; factors contributing to wildlife declines; trends in human numbers; international deliberations about the impacts of human population growth; and the implications for the future of wildlife conservation in the UK. The evidence-based text includes comparisons of wildlife declines and their causes in other countries, providing a global perspective. This book is for ecologists, naturalists and conservation biologists studying and working in academia or in consultancies, as well as all those interested in wildlife conservation.

Shallow subterranean habitats (SSHs) are areas of habitable space that are less than 10 m in depth from the surface. These range from large areas such as shallow caves and lava tubes, to tiny areas such as cracks in ceilings, or spaces in soil. Whilst being very different in many ways, they are often bound together by shared characteristics of the habitats and their faunas, and their study can help us to understand subterranean habitats in general. This book concentrates on the more typical SSHs of intermediate size (seepage springs, spaces between rocks, cracks in lava etc.), describing the habitats, their fauna, and the ecological and evolutionary questions posed. Similarities and differences between the habitats are considered and discussed in a broader ecological and evolutionary context. The book is mainly aimed at students and researchers in the field of subterranean biology, but will also be of interest to a wider range of ecologists, evolutionary biologists, freshwater biologists, and conservationists. There will also be an audience of environmental professionals.

Theoretical Ecology: concepts and applications continues the authoritative and established sequence of theoretical ecology books initiated by Robert M. May which helped pave the way for ecology to become a more robust theoretical science, encouraging the modern biologist to better understand the mathematics behind their theories. This latest instalment builds on the legacy of its predecessors with a completely new set of contributions. Rather than placing emphasis on the historical ideas in theoretical ecology, the Editors have encouraged each contribution to: synthesize historical theoretical ideas within modern frameworks that have emerged in the last 10-20 years (e.g. bridging population interactions to whole food webs); describe novel theory that has emerged in the last 20 years from historical empirical areas (e.g. macro-ecology); and finally to cover the rapidly expanding area of theoretical ecological applications (e.g. disease theory and global change theory). The result is a forward-looking synthesis that will help guide the field through a further decade of discovery and development. It is written for upper level undergraduate students, graduate students, and researchers seeking synthesis and the state of the art in growing areas of interest in theoretical ecology, genetics, evolutionary ecology, and mathematical biology.
