The cheetah is an endangered species, threatened with extinction due to loss of habitat and conflict with humans for land use and prey animals. Although international efforts to save the cheetah include co-ordinated multi-national breeding programmes, the captive cheetah population is not yet self-sustaining. Understanding of cheetah biology has increased dramatically in recent decades but the domestic cat is still commonly used as a model species for the cheetah in captivity when it comes to nutrition and reproduction. However, is it really fair to extrapolate the nutritional requirements or reproductive anomolies of the domestic cat to its distant relative the cheetah? This book reviews the known differences and similarities in cheetah and cat biology, with particular reference to their nutritional and reproductive physiology. Where examples from either species are missing, comparison is made with other members of the Felidae in order to estimate the likelihood of interspecific differences between the cheetah and cat. The comparisons made here have particular relevance for the fomulation of diets for captive cheetahs and the development of zoo-based breeding programmes. Furthermore, this book provides zoo managers, breeding co-ordinators, veterinarians and nutritionists with a valuable tool when attempting to identify and correct nutritional inadequacies or reproductive dysfunction in the cheetah.

Over half a billion years ago life on earth took an incredible step in evolution, when animals learned to build skeletons. Using many different materials, from calcium carbonate and phosphate, and even silica, to make shell and bone, they started creating the support structures that are now critical to most living forms, providing rigidity and strength. Manifesting in a vast variety of forms, they provided the framework for sophisticated networks of life that fashioned the evolution of Earth's oceans, land, and atmosphere. Within a few tens of millions of years, all of the major types of skeleton had appeared. Skeletons enabled an unprecedented array of bodies to evolve, from the tiniest seed shrimp to the gigantic dinosaurs and blue whales. The earliest bacterial colonies constructed large rigid structures - stromatolites - built up by trapping layers of sediment, while the mega-skeleton that is the Great Barrier Reef is big enough to be visible from space. The skeletons of millions of coccolithophores that lived in the shallow seas of the Mesozoic built the white cliffs of Dover. These, and insects, put their scaffolding on the outside, as an exoskeleton, while vertebrates have endoskeletons. Plants use tubes of dead tissue for rigidity and transport of liquids - which in the case of tall trees need to be strong enough to extend 100 m or more from the ground. Others simply stitch together a coating from mineral grains on the seabed. In Skeletons, Jan Zalasiewicz and Mark Williams explore the incredible variety of the skeleton innovations that have enabled life to expand into a wide range of niches and lifestyles on the planet. Discussing the impact of climate change, which puts the formation of some kinds of skeleton at risk, they also consider future skeletons, including the possibility that we might increasingly incorporate metal and plastic elements into our own, as well as the possible materials for skeleton building on other planets.
Introduces readers to the roles of bees in world ecosystems, as well as threats to bee populations and conservation efforts. Eye-catching infographics, clear text, and a "That's Amazing!" feature make this book an engaging exploration of the importance of bees.
This book presents a biographical history of the field of systems thinking, by examining the life and work of thirty of its major thinkers. It discusses each thinker's key contributions, the way this contribution was expressed in practice and the relationship between their life and ideas. This discussion is supported by an extract from the thinker's own writing, to give a flavour of their work and to give readers a sense of which thinkers are most relevant to their own interests.
Consciously or not, wildlife managers generally act from a theoretical basis, although they may not be fully versed in the details or ramifications of that theory. In practice, the predictions of the practitioners sometimes prove more accurate than those of the theoreticians. Practitioners and theoreticians need to work together, but this proves difficult when new management ideas and cutting-edge ecological theory are often published in separate scientific outlets with distinctly different readerships. A compilation of the scientific papers presented at the Caesar Kleberg Wildlife Research Institute's 25th Anniversary Conference of April 2006, Wildlife Science: Linking Ecological Theory and Management Applications brings together these two often separate approaches to elucidate the theoretical underpinnings of wildlife management and to apply evolving ecological concepts to changes and adaptations in management practices. Gathering many of the best and greatest minds in wildlife science, this volume addresses the critically important theme of linking ecological theory and management applications. Divided into five parts, the first two parts deal with the landscape ecology of birds and mammals respectively, demonstrating the need for applied theory in gamebird management and the preservation of the cougar. Part three highlights the role of climate when applying ecological theory to habitat management and discusses the emergence of ecosystem management in managing wildlife at the ecosystem scale. Part four considers the management of wildlife disease and reveals the increasing importance of genetics in conservation and ecology. Finally, the economic and social issues affecting wildlifescience round out the coverage in part five. Applying emerging ecological theory for the advancement of wildlife management, Wildlife Science: Linking Ecological Theory and Management Applications provides a long awaited cooperative look at the future of ecosystem management.
The Class Mammalia is amazingly diverse, ranging from whales to marsupials to bats to primates. The more than 5,400 species occupy many habitats, with mammals present on all the continents. They are rare only on Antarctica and a few isolated islands. Mammals present a complex set of conservation and management issues. Some species have become more numerous with the rise of human populations, while others have been extirpated or nearly so-such as the Caribbean monk seal, the thylacine, the Chinese river dolphin, and the Pyrenean ibex. In this new edition of their classic textbook, George A. Feldhamer and his colleagues cover the many aspects of mammalogy. Thoroughly revised and updated, this edition includes treatments of the most recent significant findings in ordinal-level mammalian phylogeny and taxonomy; special topics such as parasites and diseases, conservation, and domesticated mammals; interrelationships between mammalian structure and function; and the latest molecular techniques used to study mammals.

This book is open access under a CC BY 4.0 license. This book breaks new ground by situating animals and their diseases at the very heart of modern medicine. In demonstrating their historical significance as subjects and shapers of medicine, it offers important insights into past animal lives, and reveals that what we think of as `human' medicine was in fact deeply zoological. Each chapter analyses an important episode in which animals changed and were changed by medicine. Ranging across the animal inhabitants of Britain's zoos, sick sheep on Scottish farms, unproductive livestock in developing countries, and the tapeworms of California and Beirut, they illuminate the multi-species dimensions of modern medicine and its rich historical connections with biology, zoology, agriculture and veterinary medicine. The modern movement for One Health - whose history is also analyzed - is therefore revealed as just the latest attempt to improve health by working across species and disciplines. This book will appeal to historians of animals, science and medicine, to those involved in the promotion and practice of One Health today.
The conventional history of animals could be more accurately described as the history of human ideas about animals. Only in the last few decades have scholars from a wide variety of disciplines attempted to document the lives of historical animals in ways that recognize their agency as sentient beings with complex intelligence. This collection advances the field further, inviting us to examine our recorded history through an animal-centric lens to discover how animals have altered the course of our collective past. The seventeen scholars gathered here present case studies from the Pacific Ocean, Africa, Europe, and the Americas, involving species ranging from gorillas and horses to salamanders and orcas. Together they seek out new methodologies, questions, and stories that challenge accepted historical assumptions and structures. Drawing upon environmental, social, and political history, the contributors employ research from such wide-ranging fields as philosophy and veterinary medicine, embracing a radical interdisciplinarity that is crucial to understanding our nonhuman past. Grounded in the knowledge that there has never been a purely human time in world history, this collection asks and answers an incredibly urgent question for historians and others interested in the nonhuman past: in an age of mass extinctions, mass animal captivity, and climate change, when we know much of what animals have done in the past, which of our activities will we want to change in the future?
A basic introduction to stick insects, examining where they live, how they grow, what they eat, and the unique traits that help to define them, such as their ability to hide on plants. Some of our world's most intriguing animals are among its creepiest. Creepy Creatures looks into the microscope, combs through fur, and investigates the outdoors to spotlight six more mini-beasts that scurry, fly, or jump. Each book matches clear text with up-close (and often startling) photos to give young readers an easy-to-follow introduction to the featured creature's body, growth process, behavior, food sources, and common habitats. Each title concludes with an activity that emphasizes the animal's defining physical characteristics.

This book provides fascinating insights into the development and genetics of evolutionary processes on the basis of animals living in the dark, such as the Astyanax cave fish. Biologically functionless traits show high variability, which results from neutral deleterious mutations no longer being eliminated by natural selection, which normally acts to preserve functional capability. These negative mutations accumulate until the traits they are responsible for become rudimentary or even lost. The random genetic basis of regressive evolution is in accordance with Nei's Neutral Theory of Molecular Evolution, which applies to the molecular level. Such processes are particularly conspicuous in species living in constant darkness, where, for example in Astyanax, all traits depending on the exposure to light, like eyes, pigmentation, visually triggered aggressive behaviour, negative phototaxis, and several peripheral outcomes of circadian rhythmicity, are useless and diminish. In compensation constructive traits like taste, olfaction or the lateral line senses are improved by selection and do not show variability. Regressive and constructive traits inherit independently, proving that the rudimentation process is not driven by pleiotropic linkage between them. All these traits are subject to mosaic evolution and exhibit unproportional epistatic gene effects, which play an important role in evolutionary adaptation and improvement. Offering valuable evolutionary insights and supplemented by a wealth of illustrations, this book will appeal to evolutionary and developmental biologists alike.
The second edition of "The Diversity of Fishes" represents a major revision of the world's most widely adopted ichthyology textbook. Expanded and updated, the second edition is illustrated throughout with striking color photographs depicting the spectacular evolutionary adaptations of the most ecologically and taxonomically diverse vertebrate group. The text incorporates the latest advances in the biology of fishes, covering taxonomy, anatomy, physiology, biogeography, ecology, and behavior. A new chapter on genetics and molecular ecology of fishes has been added, and conservation is emphasized throughout. Hundreds of new and redrawn illustrations augment readable text, and every chapter has been revised to reflect the discoveries and greater understanding achieved during the past decade.

Costa Rica is a remarkable place for amphibians and reptiles. Known for its biological diversity, conservation priorities, and extensive protected lands, this small country contains 418 herpetological species including the dangerous Fer-de-Lance and Black-headed Bushmaster, the beloved sea turtles, and numerous dink, foam, glass, and rain frogs. Additional species are thought to be nearing extinction while others have been introduced only recently.
Amphibians and Reptiles of Costa Rica is the perfect introductory guide to this diverse herpetofauna in a format that makes it easy to carry into the field. The focus is on identification with entries for all species in the country, including scientific and English common names, as well as the older names for the many species that have been recently reclassified. Key ID marks are noted as well as adult sizes. Range maps identify the region(s) where species are known to be present. Color photographs and drawings are provided for over 80 percent of the species, representing those that are most likely to be encountered. Designed with ease of use in mind, this guide will be a great aid to the observer in identifying the specimen at hand.
A unique, beautifully illustrated exploration of our fascination with our closest primate relatives, and the development of primatology as a discipline This insightful work is a compact but wide-ranging survey of humankind's relationship to the great apes (chimpanzees, bonobos, gorillas, orangutans), from antiquity to the present. Replete with fascinating historical details and anecdotes, it traces twists and turns in our construction of primate knowledge over five hundred years. Chris Herzfeld outlines the development of primatology and its key players and events, including well-known long-term field studies, notably the pioneering work by women such as Jane Goodall, Dian Fossey, and Birute Galdikas. Herzfeld seeks to heighten our understanding of great apes and the many ways they are like us. The reader will encounter apes living in human families, painting apes, apes who use American Sign Language, and chimpanzees who travelled in space. A philosopher and historian specializing in primatology, Herzfeld offers thought-provoking insights about our perceptions of apes, as well as the boundary between "human" and "ape" and what it means to be either.
This book focuses on Blakiston's fish owl and the red-crowned crane as umbrella species. Healthy river, riparian and wetland ecosystems are necessary to maintain the populations of the two species. Both species have been revered by people since ancient times, but both are currently listed as endangered because of their small population sizes. The population decline of the two species can be mainly attributed to the degradation of the natural riparian and wetland habitats, which is associated with land use development. The populations of the two species are now recovering in Japan due to recent conservation and reproduction efforts, but the genetic diversity of the two species are still low due to previous bottleneck effects. To develop conservation and dispersal plans to establish the species over the East Asian mainland and on the island of Hokkaido, basic information, such as their regional distribution, genetic diversity, food availability, reproductive traits, and nesting, breeding, rearing, and commuting habitat, is essential. The intensive, collaborative studies conducted in Japan and Russia has clarified the status quo and the ecology of the two species. This is the first book that comprehensively compiles the above information for the mainland and island populations. In addition, it verifies their suitability as umbrella species of an ecosystem and the possibility of their future population expansion, taking into account changes in land use in Hokkaido, which is about to experience a dramatic decline in human population. As such, the book provides valuable information for students who wish to learn about these beautiful symbolic creatures, for NGOs engaged in conservation activities, and for managers who are involved in creating conservation plans and implementing restoration projects.
Groupers of the World is a detailed but easy-to-use guide to all of the more than 160 recognised species, of these mostly large, colourful tropical reef fishes, also known as rockcod. The book has detailed line drawings of each species and more than 350 colour photographs depicting the living fish in their natural habitat as well as dead specimens, mostly photographed in markets. Photographs show distinctive colour differences between adults and juveniles, as well as regional colour variations. The wealth of photographs and illustrations together with clear descriptions allow for reliable identification of any of the species, even by those unfamiliar with groupers. Together with the outstanding photographs of these remarkable and important fishes, Groupers of the World has up-to-date biological, ecological and population information for each species. Individual colour maps and descriptions summarise the known distribution of each of the groupers. Groupers are increasingly being harvested for the live food fish trade, and many species are experiencing serious population declines. The IUCN Species Survival Commission (Groupers & Wrasses Specialist Group) has been responsible for compiling the available data so as to evaluate the status and present a summary of threats to each species. The bibliography of almost 1000 references will be very useful to anyone working in the field. Groupers of the World: a Field and Market Guide is an indispensable publication for fisheries scientists and managers as well as divers, anglers and those with an interest in reef fishes in general.
Nutrition has long been considered more the domain of medicine and agriculture than of the biological sciences, yet it touches and shapes all aspects of the natural world. The need for nutrients determines whether wild animals thrive, how populations evolve and decline, and how ecological communities are structured. "The Nature of Nutrition" is the first book to address nutrition's enormously complex role in biology, both at the level of individual organisms and in their broader ecological interactions.
Stephen Simpson and David Raubenheimer provide a comprehensive theoretical approach to the analysis of nutrition--the Geometric Framework. They show how it can help us to understand the links between nutrition and the biology of individual animals, including the physiological mechanisms that determine the nutritional interactions of the animal with its environment, and the consequences of these interactions in terms of health, immune responses, and lifespan. Simpson and Raubenheimer explain how these effects translate into the collective behavior of groups and societies, and in turn influence food webs and the structure of ecosystems. Then they demonstrate how the Geometric Framework can be used to tackle issues in applied nutrition, such as the problem of optimizing diets for livestock and endangered species, and how it can also help to address the epidemic of human obesity and metabolic disease
Drawing on a wealth of examples from slime molds to humans, "The Nature of Nutrition" has important applications in ecology, evolution, and physiology, and offers promising solutions for human health, conservation, and agriculture.
In the songs and bubble feeding of humpback whales; in young killer whales learning to knock a seal from an ice floe in the same way their mother does; and in the use of sea sponges by the dolphins of Shark Bay, Australia, to protect their beaks while foraging for fish, we find clear examples of the transmission of information among cetaceans. Just as human cultures pass on languages and turns of phrase, tastes in food (and in how it is acquired), and modes of dress, could whales and dolphins have developed a culture of their very own? Unequivocally: yes. In The Cultural Lives of Whales and Dolphins, cetacean biologists Hal Whitehead, who has spent much of his life on the ocean trying to understand whales, and Luke Rendell, whose research focuses on the evolution of social learning, open an astounding porthole onto the fascinating culture beneath the waves. As Whitehead and Rendell show, cetacean culture and its transmission are shaped by a blend of adaptations, innate sociality, and the unique environment in which whales and dolphins live: a watery world in which a hundred-and-fifty-ton blue whale can move with utter grace, and where the vertical expanse is as vital, and almost as vast, as the horizontal. Drawing on their own research as well as a scientific literature as immense as the sea--including evolutionary biology, animal behavior, ecology, anthropology, psychology, and neuroscience--Whitehead and Rendell dive into realms both humbling and enlightening as they seek to define what cetacean culture is, why it exists, and what it means for the future of whales and dolphins. And, ultimately, what it means for our future, as well.
This book brings together scientific evidence and experience relevant to the practical conservation of wild birds. The authors worked with an international group of bird experts and conservationists to develop a global list of interventions that could benefit wild birds. For each intervention, the book summarises studies captured by the Conservation Evidence project, where that intervention has been tested and its effects on birds quantified. The result is a thorough guide to what is known, or not known, about the effectiveness of bird conservation actions throughout the world. The preparation of this synopsis was funded by the Natural Environment Research Council and Arcadia.
With rich detail and vibrancy, internationally recognized experts across several fields address the evolution and phylogenetic relationships of the Arthropoda . They offer innovative ideas to reevaluate the phylogeny of major arthropod groups, discuss the evolution of arthropod eyes in a phylogenetic context, present a comprehensive overview of appendage loss and regeneration, and address the most recent molecular phylogenetic data, including nuclear and mitochondrial DNA sequences. They also discuss relationships between insects and crustaceans, offer diverse approaches to evaluate fossil evidence, and evaluate competing hypotheses for arthropod placement in the animal kingdom. .,."contributes important new insights into the rapidly changing field of evolutionary relationship within the arthropods, revealing a process in which the traditional view of phylogenetic relationships is being reevaluated and revolutionized. ...Fred Schram, as well as the many researchers honouring him with this volume, have markedly advanced our present understanding of arthropod phylogeny, while also providing a template for testing of arthropod relationships as the field advances in years to come." -Christoph D. Schubart, Universitat Regensburg and Carsten H. G. Muller, Institut fur Biowissenschaften, Universitat Rostock, Germany, Systematic Biology, Vol. 55 "It is a highly appropriate collection of thought-provoking and innovative papers...which should do Fred Schram proud. ...for anyone who is interested in current views on arthropods and/or crustacean relationships, and who does not shy away from interpretations that deviate strongly from the general views, this is a must-have volume." -Contributions toZoology "Reassuringly, perhaps, like any other multiauthored volume dealing with aspects of arthropod phylogeny, this one includes plenty that is controversial. ...This book...will serve as a marker in the development of ideas of crustacean and arthropod relationships." -Derek E.G. Briggs, Department of Geology and Geophysics, Yale University, The Palaeontology Newsletter, Vol. 61
Ecology and Conservation of Forest Birds is a unique review of current understanding of the relationships between forest birds and their changing environments. Large ecological changes are being driven by forest management, climate change, introduced pests and pathogens, abiotic disturbances, and overbrowsing. Many forest bird species have suffered population declines, with the situation being particularly severe for birds dependent on attributes such as dead wood, old trees and structurally complex forests. With a focus on the non-tropical parts of the Northern Hemisphere, the text addresses the fundamental evolutionary and ecological aspects of forest birds using original data analyses and synthesising reviews. The characteristics of bird assemblages and their habitats in different European forest types are explored, together with the macroecological patterns of bird diversity and conservation issues. The book provides a valuable reference for ecologists, ornithologists, conservation professionals, forest industry employees, and those interested in birds and nature.
Islands are special places; they can be havens for unique plants and animals and refuges for wildlife. This book investigates the biogeography of butterfly species over the British islands, particularly the factors that influence their presence on the islands and that have made each island's butterfly fauna distinctive. The book contains a full log of records of species on the islands and much supporting information. The first three chapters set the scene, illustrating the basics of island biogeography theory, their changing circumstances during the current Holocene interglacial, and studies of natural history of British butterflies that mark the islands as the most intensively studied region for wildlife in the world. The book advances by increasing resolution downscale from a European continental perspective, through patterns and changes on the British mainland, a comparison of the two dominant islands of Britain and Ireland, to a close inspection of the dynamics of species on the multitude of offshore islands. Detailed investigations include contrasts in species' richness on the islands and then of the incidences of each species. Case studies highlight the continual turnover of species on islands. Attention is then given to evolutionary changes since the time that glaciers enveloped Europe. A powerful message is conveyed for the maintenance of butterfly species on the smaller British islands now experiencing population losses at a rate unprecedented since the spread of the last ice sheets: the incontrovertible importance of maintaining populations of species on nearby mainland sources for islands as pools for future migrants. This book is enhanced with supporting material. To access the Online Supplementary Appendices below, please visit: http://www.cabi.org/openresources/95061.
