The Eurasian Beaver (Paperback): Roisin Campbell-Palmer, Derek Gow, Robert Needham, Simon Jones, Frank Rosell The Eurasian Beaver (Paperback)
Roisin Campbell-Palmer, Derek Gow, Robert Needham, Simon Jones, Frank Rosell
R371 Discovery Miles 3 710 Ships in 12 - 17 working days

The Eurasian beaver was near extinction at the start of the twentieth century, hunted across Europe for its fur, meat and castoreum. But now the beaver is on the brink of a comeback, with wild beaver populations, licensed and unlicensed, emerging all over Britain. As a keystone species, the beaver plays a vital role in the creation of sustainable wetland habitats through its damming activities, providing living opportunities for a broad spectrum of wildlife. Yet as proposals for reintroducing beavers are underway, re-establishing the beaver in Britain is still a controversial issue. This book presents a case for our future coexistence with beavers by providing factual information on this species that has now passed from national memory, covering the biology, behaviour and ecology of the Eurasian beaver in a British context, from their early history in archaeology and folklore to their contemporary field signs in the wild. This book familiarises readers once again, after almost 400 years of its absence, with the Eurasian beaver, providing essential information on its requirements in our human dominated landscape. This book is for those with a specific interest in beavers and their reintroduction, and for anyone with a general curiosity in natural history, ecology or animal behaviour. It can be used as a field guide to identify beaver field signs and observe beavers in the wild by wildlife surveyors or general land users, or as an introductory guide for anyone with an interest in beavers and how to recognise them. The authors have been actively involved in the study of beaver ecology, behaviour and reintroduction for many years. They have a first-hand knowledge of beavers in captivity and in the wild in both Britain and a range of other European countries.

The Design of Mammals - A Scaling Approach (Paperback): John William Prothero The Design of Mammals - A Scaling Approach (Paperback)
John William Prothero
R1,175 Discovery Miles 11 750 Ships in 10 - 15 working days

Despite an astonishing 100 million-fold range in adult body mass from bumblebee bat to blue whale, all mammals are formed of the same kinds of molecules, cells, tissues and organs and to the same overall body plan. A scaling approach investigates the principles of mammal design by examining the ways in which mammals of diverse size and taxonomy are quantitatively comparable. This book presents an extensive reanalysis of scaling data collected over a quarter of a century, including many rarely or never-cited sources. The result is an unparalleled contribution to understanding scaling in mammals, addressing a uniquely extensive range of mammal attributes and using substantially larger and more rigorously screened samples than in any prior works. An invaluable resource for all those interested in the 'design' of mammals, this is an ideal resource for postgraduates and researchers in a range of fields from comparative physiology to ecology.

Marmot Biology - Sociality, Individual Fitness, and Population Dynamics (Paperback): Kenneth B. Armitage Marmot Biology - Sociality, Individual Fitness, and Population Dynamics (Paperback)
Kenneth B. Armitage
R1,730 Discovery Miles 17 300 Ships in 10 - 15 working days

Focusing on the physiological and behavioral factors that enable a species to live in a harsh seasonal environment, this book places the social biology of marmots in an environmental context. It draws on the results of a forty-year empirical study of the population biology of the yellow-bellied marmot near the Rocky Mountain Biological Laboratory in the Upper East River Valley in Colorado, USA. The text examines life-history features such as body-size, habitat use, environmental physiology, social dynamics, and kinship. Considerable new data analyses are integrated with material published over a fifty-year period, including extensive natural history observations, providing an essential foundation for integrating social and population processes. Finally, the results of research into the yellow-bellied marmot are related to major ecological and evolutionary theories, especially inclusive fitness and population regulation, making this a valuable resource for students and researchers in animal behavior, behavioral ecology, evolutionary biology, ecology and conservation.

Weaner Pig - Nutrition and Management (Hardcover): Mike A. Varley, Julian Wiseman Weaner Pig - Nutrition and Management (Hardcover)
Mike A. Varley, Julian Wiseman
R3,737 Discovery Miles 37 370 Ships in 12 - 17 working days

Weaning represents a significant challenge to every young piglet and the success of the process is crucial to the lifetime performance of the animal. The transition from a liquid diet to one that is usually based on dry food ingredients is accompanied by major changes in digestive physiology, immune status and social and physical environments. Successful weaning is, therefore, the key to effective growth, feed efficiency and the subsequent development of the pig. This book has been developed from a British Society of Animal Science occasional meeting, held in September 2000. "The Weaner Pig: Nutrition and Management" brings together all the scientific disciplines involved in the pre- and post-weaning biology of the piglet, concentrating on growth/development, nutrition, immunology/health, ethology and the physical environment.

A Guide to the Carnivores of Central America - Natural History, Ecology, and Conservation (Paperback): Carlos L. de la Rosa,... A Guide to the Carnivores of Central America - Natural History, Ecology, and Conservation (Paperback)
Carlos L. de la Rosa, Claudia C. Nocke
R924 Discovery Miles 9 240 Ships in 12 - 17 working days

Carnivores such as pumas, jaguars, and ocelots have roamed the neotropical forests of Central America for millennia. Enshrined in the myths of the ancient Maya, they still inspire awe in the region's current inhabitants, as well as in the ecotourists and researchers who come to experience Central America's diverse and increasingly endangered natural environment.

This book is one of the first field guides dedicated to the carnivores of Central America. It describes the four indigenous families -- wild cats, raccoons and their relatives, skunks and their relatives, and wild canids -- and their individual species that live in the region. The authors introduce each species by recounting a first-person encounter with it, followed by concise explanations of its taxonomy, scientific name, English and Spanish common names, habitat, natural history, and conservation status. Range maps show the animal's past and current distribution, while Claudia Nocke's black-and-white drawings portray it visually.

The concluding chapter looks to the carnivores' future, including threats posed by habitat destruction and other human activities, and describes some current conservation programs. Designed for citizens of and visitors to Central America, as well as specialists, this book offers an excellent introduction to a group of fascinating, threatened, and still imperfectly understood animals.

The authors have studied Central American carnivores for many years. Carlos L. de la Rosa is Director of the Florida Center for Environmental Studies' Riverwoods Field Laboratory in south Florida, where Claudia C. Nocke is currently working on a Ph.D.

British Bat Calls - A Guide to Species Identification (Paperback): Jon Russ British Bat Calls - A Guide to Species Identification (Paperback)
Jon Russ; Contributions by Bat Conservation Trust
R1,049 Discovery Miles 10 490 Ships in 12 - 17 working days

Knowledge of bat echolocation and social calls, and identification using ultrasonic 'bat detectors' and sound analysis software, has grown significantly in the last decade. In this practical guide Jon Russ and contributors (Kate Barlow, Philip Briggs & Sandie Sowler) present the latest information in a clear and concise manner. The book covers topics including the properties of sound, how bats use sound, bat detectors and recording devices, analysis software, and call analysis. For each species found in the British Isles, information is given on distribution, emergence times, flight and foraging behaviour, habitat, echolocation calls including parameters for common measurements, and social calls. Calls are described in the context of the different technologies employed to record them (heterodyne, frequency division and time expansion). Various sonograms for each species are displayed in BatSound and AnaLookW. A species echolocation guide is included.

A Dog's World - Imagining the Lives of Dogs in a World without Humans (Paperback): Jessica Pierce, Marc Bekoff A Dog's World - Imagining the Lives of Dogs in a World without Humans (Paperback)
Jessica Pierce, Marc Bekoff
R395 Discovery Miles 3 950 Ships in 12 - 17 working days

From two of the world’s leading authorities on dogs, an imaginative journey into a future of dogs without people What would happen to dogs if humans simply disappeared? Would dogs be able to survive on their own without us? A Dog’s World imagines a posthuman future for dogs, revealing how dogs would survive—and possibly even thrive—and explaining how this new and revolutionary perspective can guide how we interact with dogs now. Drawing on biology, ecology, and the latest findings on the lives and behavior of dogs and their wild relatives, Jessica Pierce and Marc Bekoff—two of today’s most innovative thinkers about dogs—explore who dogs might become without direct human intervention into breeding, arranged playdates at the dog park, regular feedings, and veterinary care. Pierce and Bekoff show how dogs are quick learners who are highly adaptable and opportunistic, and they offer compelling evidence that dogs already do survive on their own—and could do so in a world without us. Challenging the notion that dogs would be helpless without their human counterparts, A Dog’s World enables us to understand these independent and remarkably intelligent animals on their own terms.

A lavishly illustrated celebration of these glorious animals-and a poignant lament for their future Elephants are among the most beloved of all creatures. Their behavior can seem almost human, from their complex social interactions to their need to mourn their dead. They are also among the most persecuted of animals, subjected to untold cruelty at the hands of humans through the ages. In this stunningly illustrated book, Errol Fuller provides a rich and moving portrait of elephants, exploring their natural history, the legends that have grown up around them, their unique place in art and literature, and their urgent need for protection today. Fuller traces the evolution of these majestic animals from prehistoric mammoths and mastodons to today's African and Asian elephants, and looks at their behavior, herd dynamics, and social life. He examines the role of elephants in cultures around the world, from folklore and fine art to the exploitation of elephants as war machines and circus animals. Fuller also discusses the importance of conservation, warning that continued poaching and habitat degradation could send these iconic animals the way of the dodo. Featuring many evocative photos never before published, Elephant is a fittingly exquisite tribute to these breathtaking creatures.

Snow Leopards: Biodiversity of the World: Conservation from Genes to Landscapes is the only comprehensive work on the biology, behavior, and conservation status of the snow leopard, a species that has long been one of the least studied, and hence poorly understood, of the large cats. Breakthroughs in technologies and methodologies to study this elusive cat have come rapidly, including non-invasive genetics, camera traps, and GPS-satellite collaring. The book begins with chapters on the genetic standing and taxonomy of the snow leopard, followed by chapters on their behavior and ecology. Additional contributions follow on the current and emerging threats to the species, which include longstanding concerns, such as poaching and conflicts with livestock, and new and emerging threats such as mining and climate change. A section on conservation solutions, backed by valuable case studies, starts with an overview of the important role mountain communities play in assuring the snow leopard's long-term persistence. In addition, chapters on the role of captive snow leopards for the conservation of the species, state-of-the-art techniques and technologies for studying and monitoring snow leopards, status reports from around the region, and future perspectives, such as transboundary conservation initiatives, international conventions (CITES, CMS, etc.), the role of the IUCN Cat Specialist Group and the Snow Leopard Network, and undertakings such as the Global Snow Leopard Forum facilitated by the World Bank are also included.

Mammal Societies (Hardcover): T Clutton-Brock Mammal Societies (Hardcover)
T Clutton-Brock
R1,584 Discovery Miles 15 840 Ships in 12 - 17 working days

The book aims to integrate our understanding of mammalian societies into a novel synthesis that is relevant to behavioural ecologists, ecologists, and anthropologists. It adopts a coherent structure that deals initially with the characteristics and strategies of females, before covering those of males, cooperative societies and hominid societies. It reviews our current understanding both of the structure of societies and of the strategies of individuals; it combines coverage of relevant areas of theory with coverage of interspecific comparisons, intraspecific comparisons and experiments; it explores both evolutionary causes of different traits and their ecological consequences; and it integrates research on different groups of mammals with research on primates and humans and attempts to put research on human societies into a broader perspective.

This revised edition of Bats of Southern and Central Africa builds on the solid foundation of the first edition and supplements the original account of bat species then known to be found in Southern and Central Africa with an additional eight newly described species, bringing the total to 124. The chapters on evolution, biogeography, ecology and echolocation have been updated, citing dozens of recently published papers. The book covers the latest systematic and taxonomic studies, ensuring that the names and relationships of bats in this new edition reflect current scientific knowledge. The species accounts provide descriptions, measurements and diagnostic characters as well as detailed information about the distribution, habitat, roosting habits, foraging ecology and reproduction of each species. The updated species distribution maps are based on 6 100 recorded localities. A special feature of the 2010 publication was the mode of identification of families, genera and species by way of character matrices rather than the more generally used dichotomous keys. Since then these matrices have been tested in the field and, where necessary, slightly altered for this edition. New photographs fill in gaps and updated sonograms aid with bat identification in acoustic surveys. The bibliography, which now contains more than 700 entries, will be an invaluable aid to students and scientists wishing to consult original research.

Bat Tree Habitat Key
R1,201 Discovery Miles 12 010 Ships in 12 - 17 working days

This is a guide to finding tree-roosts. It is the result of the collaborative efforts of professional surveyors and amateur naturalists across Europe as part of the Bat Tree Habitat Key project, and represents a combination of firsts: It is the first time legislation and planning policy have been reviewed and put to practical use to define an analysis framework with clearly identifiable thresholds for action. Yet, despite its efficacy in a professional context, it is also the first time a guide has been produced that is equally effective in achieving its objective for amateurs. It is the first time such a method has been evidence-supported throughout, with summary reviews of each aspect of the roosting ecology of the individual 14 tree-roosting species, with illustrative photographs and data to which the reader has open access. It is the first time a repeatable analysis framework has been defined against which the surveyor may compare their results at every stage, from the desk-study, through ground-truthing, survey and analysis, thereby ensuring nothing is overlooked and that every result can be objectively compared. The survey and analysis framework itself is ground-breaking in that it may readily be adapted for any taxa; from moths, through amphibians, reptiles, birds and all other mammals. Used diligently, these methods will reward disproportionately and imbue the reader with renewed confidence as they quickly progress from beginner to competency. Thus, this book is for everyone who has ever wanted to find a tree-roost, or to safeguard against inadvertently damaging one.

Zebra Stripes (Hardcover): Tim Caro Zebra Stripes (Hardcover)
Tim Caro
R1,339 Discovery Miles 13 390 Ships in 12 - 17 working days

From eminent biologists like Alfred Russel Wallace and Charles Darwin to famous authors such as Rudyard Kipling in his Just So Stories, many people have asked, "Why do zebras have stripes?" There are many explanations, but until now hardly any have been seriously addressed or even tested. In Zebra Stripes, Tim Caro takes readers through a decade of painstaking fieldwork examining the significance of black-and-white striping and, after systematically dismissing every hypothesis for these markings with new data, he arrives at a surprising conclusion: zebra's markings are nature's defense against biting fly annoyance. Popular explanations for stripes range from camouflage to confusion of predators, social facilitation, and even temperature regulation. It is a challenge to test these proposals on large animals living in the wild, but using a combination of careful observations, simple field experiments, comparative information, and logic, Caro is able to weigh up, scientifically, the pros and cons of each idea. Eventually driven by experiments showing that biting flies avoid landing on striped surfaces, observations that striping is most intense where biting flies are abundant, and by his knowledge of zebras' susceptibility to biting flies and vulnerability to the diseases that flies carry Caro concludes that black-and-white stripes are an adaptation to thwart biting fly attack. Not just a tale of one scientist's quest to solve a classic mystery of biology, Zebra Stripes is also a testament to the tremendous value of longitudinal research in behavioral ecology, demonstrating how observation, experiment, and comparative research can reshape our understanding of the natural world.

Humans and Hyenas - Monster or Misunderstood (Hardcover): Keith Somerville Humans and Hyenas - Monster or Misunderstood (Hardcover)
Keith Somerville
R3,913 Discovery Miles 39 130 Ships in 12 - 17 working days

Humans and Hyenas examines the origins and development of the relationship between the two to present an accurate and realistic picture of the hyena and its interactions with people. The hyena is one of the most maligned, misrepresented and defamed mammals. It is still, despite decades of research-led knowledge, seen as a skulking, cowardly scavenger rather than a successful hunter with complex family and communal systems. Hyenas are portrayed as sex-shifting deviants, grave robbers and attackers of children in everything from African folk tales through Greek and Roman accounts of animal life, to Disney's The Lion King depicting hyenas with a lack of respect and disgust, despite the reality of their behaviour and social structures. Combining the personal, in-depth mining of scientific papers about the three main species and historical accounts, Keith Somerville delves into our relationship with hyenas from the earliest records from millennia ago, through the accounts by colonisers, to contemporary coexistence, where hyenas and humans are forced into ever closer proximity due to shrinking habitats and loss of prey. Are hyenas fated to retain their bad image or can their amazing ability to adapt to humans more successfully than lions and other predators lead to a shift in perspective? This book will be of great interest to students and scholars in the environmental sciences, conservation biology, and wildlife and conservation issues.

Justin Kestler
R893 Discovery Miles 8 930 Ships in 12 - 17 working days

Mammalian predators are keystone species in any ecosystem. But many are elusive by nature and have territories that cover large areas of land, which makes them challenging to monitor. When tracks and signs prove difficult to interpret or are non-existent, hair samples recovered from the field offer a fantastic resource – one that is often overlooked. The Hair Scale Identification Guide to Terrestrial Mammalian Carnivores of Canada provides a fully illustrated, up-to-date hair scale reference for all 25 of the terrestrial carnivorous mammals of Canada. From the tiny least weasel (Mustela nivalis) to the giant polar bear (Ursus maritimus), unique traits – as well as tricky similarities – can clearly be observed through hair scale patterns magnified at the medial portion of the hair impression. These scale patterns aid in species identification when hair is the only possible evidence available. This guide also outlines hair impression techniques for samples found in the field, assisting ecologists and technicians with wildlife monitoring studies on predatory mammals where additional identification is required. Including range maps and key identification characteristics for all species represented, as well as superb images of hair scale impressions at two magnification levels, this book is a comprehensive tool for animal hair ID.

Throughout North America, non-native wild pigs have become an ecologically and economically destructive invasive species. Though they are regarded as a popular game species by some, provide economic benefits to others, and are even engrained into societal heritage in some areas, wild pigs are responsible for an extraordinary amount of damage in both natural and anthropogenic systems throughout North America. As the density and range of wild pig habitat have substantially increased over the last several decades, the magnitude and diversity of their negative impacts are not yet fully realized or quantified. With various conflicts continually emerging, wild pig management is difficult and expensive to achieve. As a result, wild pigs represent one of the greatest wildlife management challenges North America faces in the 21st century. Invasive Wild Pigs in North America: Ecology, Impacts, and Management addresses all aspects of wild pig biology, ecology, damage, and management in a single comprehensive volume. It assimilates and organizes information on the most destructive introduced vertebrate species in the United States, establishing a foundation from which managers, researchers, policy makers, and other stakeholders can build upon into the future. The book provides comprehensive coverage of wild pig biology and ecology, techniques for management and research, and regional chapters. It is an asset to readers interested in wild pigs, the resources they impact, and how to mitigate those impacts, and establishes a vision of the future of wild pigs in North America. Features: Compiles valuable knowledge for a broad audience including wild pig managers, researchers, adversaries, and enthusiasts from across North America Addresses taxonomy, morphology, genetics, physiology, spatial ecology, population dynamics, diseases and parasites, and the naturalized niche of wild pigs Includes chapters on damage to resources, management, research methods, human dimensions and education, and policy and legislation Contains full color images and case studies of interesting and informative situations being created by wild pigs throughout North America Includes a chapter on wild pigs at the wildland-urban interface, a more recent and especially challenging issue
