"Cheetahs of the Serengeti Plains" is the most comprehensive account of carnivore social behavior to date. Synthesizing more than a decade of research in the wild, this book offers a detailed account of the behavior and ecology of cheetahs. Compared with other large cats, and other mammals, cheetahs have an unusual breeding system; whereas lions live in prides and tigers are solitary, some cheetahs live in groups while others live by themselves. Tim Caro explores group and solitary living among cheetahs and discovers that the causes of social behavior vary dramatically, even within a single species.
Why do cheetah cubs stay with their mother for a full year after weaning? Why do adolescents remain in groups? Why do adult males live in permanent associations with each other? Why do adult females live alone? Through observations on the costs and benefits of group living, Caro offers new insight into the complex behavior of this extraordinary species. For example, contrary to common belief about cooperative hunting in large carnivores, he shows that neither adolescents nor adult males benefit from hunting in groups.
With many surprising findings, and through comparisons with other cat species, Caro enriches our understanding of the evolution of social behavior and offers new perspectives on conservation efforts to save this charismatic and endangered carnivore.

Many infectious diseases of recent concern, including malaria, cholera, plague, and Lyme disease, have emerged from complex ecological communities, involving multiple hosts and their associated parasites. Several of these diseases appear to be influenced by human impacts on the environment, such as intensive agriculture, clear-cut forestry, and habitat loss and fragmentation; such environmental impacts may affect many species that occur at trophic levels below or above the hostcommunity. These observations suggest that the prevalence of both human and wildlife diseases may be altered in unanticipated ways by changes in the structure and composition of ecological communities. Predicting the epidemiological ramifications of such alteration in community composition will require strengthening the current union between community ecology and epidemiology.

Why are some kinds of organism species-rich and others species-poor? How do new species arise and why do some go extinct? Why do organisms grow and behave the way they do? This book provides an introduction to evolutionary ecology, the science that brings ecology and evolution together to help understand biological diversity. In a concise, readable format, Peter Mayhew covers the entire breadth of the subject, from life histories and the evolution of sex, to speciation and macroecology. Many emerging fields are also introduced, such as metabolic ecology, the evolution of population dynamics, and the evolution of global ecology. Discovering Evolutionary Ecology highlights the connections between these different subject areas, and for the first time paints a picture of a truly integrated field. It illustrates the research tools utilized, and demonstrates how advances in one area can spur on developments elsewhere when scientists combine evolutionary and ecological knowledge. To maximize accessibility, the book assumes only a basic knowledge of biology, includes a comprehensive glossary, and contains almost no maths. Each chapter provides suggestions for further reading, and there is also an extensive reference list. Ideal as an introduction to evolutionary ecology for undergraduates, this book will also interest established researchers, providing a broad and up-to-date context for their work.

Urban Evolutionary Biology fills an important knowledge gap on wild organismal evolution in the urban environment, whilst offering a novel exploration of the fast-growing new field of evolutionary research. The growing rate of urbanization and the maturation of urban study systems worldwide means interest in the urban environment as an agent of evolutionary change is rapidly increasing. We are presently witnessing the emergence of a new field of research in evolutionary biology. Despite its rapid global expansion, the urban environment has until now been a largely neglected study site among evolutionary biologists. With its conspicuously altered ecological dynamics, it stands in stark contrast to the natural environments traditionally used as cornerstones for evolutionary ecology research. Urbanization can offer a great range of new opportunities to test for rapid evolutionary processes as a consequence of human activity, both because of replicate contexts for hypothesis testing, but also because cities are characterized by an array of easily quantifiable environmental axes of variation and thus testable agents of selection. Thanks to a wide possible breadth of inference (in terms of taxa) that may be studied, and a great variety of analytical methods, urban evolution has the potential to stand at a fascinating multi-disciplinary crossroad, enriching the field of evolutionary biology with emergent yet incredibly potent new research themes where the urban habitat is key. Urban Evolutionary Biology is an advanced textbook suitable for graduate level students as well as professional researchers studying the genetics, evolutionary biology, and ecology of urban environments. It is also highly relevant to urban ecologists and urban wildlife practitioners.

As sequel to Aquatic Animal Nutrition - A Mechanistic Perspective from Individuals to Generations, the present treatise on organic macro- and micronutrients continues the unique cross fertilization of aquatic ecology/ecophysiology and aquaculture. This treatise considers proteins and their constituents, carbohydrates from mono- to polysaccharides, fatty acids from free acids to fat, and waxes. It becomes obvious that these organic nutrients are more than only simple fuel for the metabolism of animals; rather, their constituents have messenger and controlling function for the actual consuming individual and even for succeeding generations. This aspect will become particularly clear by putting the organisms under consideration back into their ecosystem with their interrelationships and interdependencies. Furthermore, micronutrients, such as vitamins and nucleotides as well as exogenous enzymes, are in the focus of this volume with known and still-to-be-discovered controlling physiological and biomolecular functions. Aquatic Animal Nutrition - Organic Macro and Micro Nutrients addresses se veral gaps in nutritional research and practice. One major gap is the lack of com mon research standards and protocols for nutritional studies so that virtually incomparable approaches have to be compared. This applies also to the studied animals, since most approaches disregard intraspecific variabilities and the existence of epimutations in farmed individuals. Furthermore, recalling the Mechanistic Perspective from Individuals to Generations, dietary benefits and deficiencies have effects on succeeding generations. In most studies, this long-term and sustainable aspect is overruled by pure short-term production aspects. By comparing nutritional behavior and success of fishes and invertebrates, Aqua tic Animal Nutrition points out different metabolic pathways in these animal groups and discusses how, for instance, fishes would benefit when having some successful metabolic pathway of invertebrates. Application of novel ge ne tic techniques will help turn this vision into reality. However, a widely missing link in the current nutritional research is epigenetics regarding transgenerational heritages of acquired morphological and physiological properties. To in crease public acceptance, nutritional optimization of farmed animals based on this mechanism, rather than genetical engineering, appears promising.

Wildfowl and screamers belong to a highly diverse family of birds, confined to watery habitats. They are amongst the most attractive of birds and are very well-known to man, who has domesticated them, used their feathers for warm clothing and ornamentation, admired their flight, courtship and migration, caught them for food, maintained them in captivity for pleasure, and written about their doings in delightful children's stories, from Mother Goose to Jemima Puddleduck and Donald Duck. They occur throughout the world except Antarctica. Some are faithful to the same partner for life, others for only the few minutes of copulation. In some species, male and female make devoted parents, and yet there is one within the group whose female lays her eggs in the nests of others and never incubates. Diving as a method of obtaining food has evolved many times within the family. Most nest in the open but others in the tree-hole nests of woodpeckers and some in the ground burrows of rabbits or aardvarks. They may be highly social or solitary, defending a large territory.
Ducks, Geese, and Swans begins with eight chapters giving an overview of the family, their taxonomy and evolution, feeding ecology, breeding strategies, social behavior, movements and migrations, population dynamics, and conservation and management, followed by accounts of 165 species, written by a team of expert wildfowl specialists, describing each bird in its natural state and summarizing the published literature and recent research. Complementing the accounts are thirty specially commissioned color plates by Mark Hulme, along with numerous black and white drawings illustrating behaviors, plus distribution maps for each species.

This authoritative guide enables accurate identification of the common components of the inshore benthic invertebrates of the British Isles and adjacent European coasts, as well as a substantial proportion of fish species. This new edition builds upon the strengths of the earlier work and is thoroughly revised throughout to incorporate advances in both the taxonomy and ecology of the organisms concerned.

This book presents the whole picture of the ecological and evolutionary study on the ground beetle group, the subgenus Ohomopterus of the genus Carabus, endemic to Japan. This flightless beetle group consists of many geographic races. They show divergence in key traits for reproductive isolation-body size and genital morphology, which leads to coexistence of two or more species. This beetle group provides an important material to study how a lineage of organisms diversify and form multi-species assemblage, and thereby multiply their species richness. The book introduces novel genomic approaches to resolve questions about evolution of Ohomopterus. The readers will find that this story of evolution in Carabus beetles revealed by recent approaches is much different from what was told in previous literature. Exploring different cases across a wide range of lineages is important in constructing a synthetic theory of species radiation and richness, including speciation and species coexistence. This study on Ohomopterus beetles contributes to the ongoing discussion to understand how and why species multiply and how species richness increases in one area of our planet.

The Heliconius butterflies are one of the classic systems in evolutionary biology and have contributed hugely to our understanding of evolution over the last 150 years. Their dramatic radiation and remarkable mimicry has fascinated biologists since the days of Bates, Wallace, and Darwin. The Ecology and Evolution of Heliconius Butterflies is the first thorough and accessible treatment of the ecology, genetics, and behaviour of these butterflies, exploring how they offer remarkable insights into tropical biodiversity. The book starts by outlining some of the evolutionary questions that Heliconius research has helped to address, then moves on to an overview of the butterflies themselves and their ecology and behaviour before focussing on wing pattern evolution, and finally, speciation. Richly illustrated with 32 colour plates, this book makes the extensive scientific literature on Heliconius butterflies accessible to a wide audience of professional ecologists, evolutionary biologists, entomologists, and amateur collectors.

Although birds have a rather uniform body plan and physiology, they exhibit marked variation in development type, parental care, and rate of growth. This makes them ideal for studying and understanding evolutionary adaptation. Presenting an integrative perspective of organism biology, ecology, and evolution, this book is a case study in evolutionary diversification of life histories.

Ecologists traditionally regard time as part of the background against which ecological interactions play out. In this book, Eric Post argues that time should be treated as a resource used by organisms for growth, maintenance, and offspring production. Post uses insights from phenology-the study of the timing of life-cycle events-to present a theoretical framework of time in ecology that casts long-standing observations in the field in an entirely new light. Combining conceptual models with field data, he demonstrates how phenological advances, delays, and stasis, documented in an array of taxa, can all be viewed as adaptive components of an organism's strategic use of time. Post shows how the allocation of time by individual organisms to critical life history stages is not only a response to environmental cues but also an important driver of interactions at the population, species, and community levels. To demonstrate the applications of this exciting new conceptual framework, Time in Ecology uses meta-analyses of previous studies as well as Post's original data on the phenological dynamics of plants, caribou, and muskoxen in Greenland.

Information on the biology of ants and various techniques for studying ants is included.

It presents the agro-ecological and evolutionary aspects of plant-insect interactions with an exclusive focus on the climate change effect on the resetting of plant-insect interactions. A valuable resource for biotechnologists, entomologists, agricultural scientists, and policymakers, the book includes theoretical aspects as a base toward real-world applications of holistic integrated pest management in agro-ecosystems.

How to decelerate loss of global biodiversity is one of the greatest challenges of our generation. Reproductive technologies have enormous potential to assist the recovery of species by enhancing reproductive output, facilitating genetic management, and supporting reintroduction of threatened species. Of particular value are cryopreservation technologies coupled with the establishment of global gene banks to conserve, in perpetuity, the remaining extant genetic diversity of threatened amphibians. Reproductive Technologies and Biobanking for the Conservation of Amphibians brings together leading experts in the field to provide a comprehensive overview of current best practices, summarise technological advancements, and present a framework for facilitating the integration of reproductive technologies and biobanking into conservation breeding programs for threatened amphibians. It is an invaluable reference for the next generation of conservation practitioners: captive breeding facilities, researchers, and policy-makers involved with biodiversity conservation

Conservation medicine focuses on the cross-over between ecosystem, animal and human health. Conservation biology emerged as a "crisis" discipline in the 1980s at the interface between ecology, environmental policy and management; and work in the biomedical and veterinary sciences is now being folded into conservation biology, to explore the connections between animal and human health. It traces the environmental sources of pathogens and pollutants in order to develop a rounded, interdisciplinary understanding of the ecological causes of changes in human and animal health, and the consequences of diseases to populations and ecological communities.

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.

Cryptic species are organisms which look identical, but which represent distinct evolutionary lineages. They are an emerging trend in organismal biology across all groups, from flatworms, insects, amphibians, primates, to vascular plants. This book critically evaluates the phenomenon of cryptic species and demonstrates how they can play a valuable role in improving our understanding of evolution, in particular of morphological stasis. It also explores how the recognition of cryptic species is intrinsically linked to the so-called 'species problem', the lack of a unifying species concept in biology, and suggests alternative approaches. Bringing together a range of perspectives from practicing taxonomists, the book presents case studies of cryptic species across a range of animal and plant groups. It will be an invaluable text for all biologists interested in species and their delimitation, definition, and purpose, including undergraduate and graduate students and researchers.

The hunting of wild animals for their meat has been a crucial activity in the evolution of humans. It continues to be an essential source of food and a generator of income for millions of Indigenous and rural communities worldwide. Conservationists rightly fear that excessive hunting of many animal species will cause their demise, as has already happened throughout the Anthropocene. Many species of large mammals and birds have been decimated or annihilated due to overhunting by humans. If such pressures continue, many other species will meet the same fate. Equally, if the use of wildlife resources is to continue by those who depend on it, sustainable practices must be implemented. These communities need to remain or become custodians of the wildlife resources within their lands, for their own well-being as well as for biodiversity in general. This title is also available via Open Access on Cambridge Core.

The chimpanzees are the closest living evolutionary relatives to our own species, Homo sapiens. As such, they have long exerted a fascination over those with an interest in human evolution, and human uniqueness. Chrisophe Boesch and Hedwige Boesch-Acherman undertook an incredible observational study of a group of wild chimpanzees in Cote D'Ivoire, spending some fifteen years in the West African forest with them. This fascinating book is the result of these years of painstaking research among the chimps. Chimpanzee behaviour is documented here in all its impressive diversity and variety, and placed within the broader context of research in behavioural ecology. The authors also succeed in shedding light on some of the central questions around the evolutionary relationships between the primates, and in particular the affinity between chimpanzees and humans.

Arthropods as pests in crops, vectors of diseases, pollinators, and natural enemies of pests are of huge economic importance. They affect livestock, human health and food supplies around the world. This unique book examines and reviews how light and colour can be used to enhance pest management in agricultural and medical applications by manipulating the optical responses of arthropods. Arthropods use optical cues to find food, oviposition sites and to navigate. Light also regulates their diurnal and seasonal activities. Plants use optical cues to attract or deter various species of arthropod. In this book, an international team of experts show how light can be used successfully to attract, arrest, confuse and deter arthropods as well as to disrupt their biological clocks. The book: Presents an up-to-date and thorough summary of what is known about how arthropods of agricultural and medical importance respond to visual cues. Describes techniques that use light to manipulate pests and beneficial insects and mites. Presents a broad discussion of the potential use of optical manipulation of arthropods to improve the health of plants, domestic animals and humans.

Reefs are an extraordinary natural phenomenon. Visible from outer space, coral reefs are the largest biologically constructed features known; in close proximity their spectacular beauty and abundance of life is dazzling. This text documents those biological innovations which have moulded the evolution of reef ecosystems and given rise to the highly complex reef communities found today. The appearance of clonality, the acquisition of photosymbiosis and the radiation of predator groups are all discussed in depth. Data from the fossil record documents the evolutionary development of reef ecosystems. This interdisciplinary approach has the aim of providing an analytical text which will be of value not only to advanced undergraduates and postgraduate courses, but also to researchers in ancient reef ecology.
