The dwarf and mouse lemurs of Madagascar are two very species-rich lemur genera, yet there is a relative paucity of information on this primate family in published literature. In this first ever treatment of the Cheirogaleidae, international experts are brought together to review and integrate our current knowledge of the behaviour, physiology, ecology, genetics and biogeography of these species. A wide range of direct and indirect research methods that are currently used to study these cryptic nocturnal solitary foragers are described. By uniting often disparate research on captive and free-ranging taxa and synthesising recent methodological advances, this book provides new insights that will encourage further studies of this fascinating primate family. This synthesis will provide an incentive for more integrative studies of the Cheirogaleidae in captivity and in the wild, enabling the impacts of deforestation and other factors to be identified and directions for future conservation efforts to be established.

The Arashiyama group of Japanese macaques holds a distinguished place in primatology as one of the longest continuously studied non-human primate populations in the world. The resulting long-term data provide a unique resource for researchers, allowing them to move beyond cross-sectional studies to tackle larger issues involving individual, matrilineal and group histories. This book presents an overview of the scope and magnitude of research topics and management efforts that have been conducted on this population for several decades, covering not only the original troop living around Kyoto, Japan, but also the two subgroups that were translocated to Texas, USA and Montreal, Canada. The chapters encompass topics including life history, sexual, social and cultural behaviour and ecology, giving an insight into the range of current primatological research. The contributors underscore the historic value of the Arashiyama macaques and showcase new and significant research findings that highlight their continuing importance to primatology.

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.

The cognitive abilities of birds are remarkable: hummingbirds integrate spatial and temporal information about food sources, day-old chicks have a sense of numbers, parrots can make and use tools, and ravens have sophisticated insights in social relationships. This volume describes the full range of avian cognitive abilities, the mechanisms behind such abilities and how they relate to the ecology of the species. Synthesising the latest research in avian cognition, a range of experts in the field provide first-hand insights into experimental procedures, outcomes and theoretical advances, including a discussion of how the findings in birds relate to the cognitive abilities of other species, including humans. The authors cover a range of topics such as spatial cognition, social learning, tool use, perceptual categorization and concept learning, providing the broader context for students and researchers interested in the current state of avian cognition research, its key questions and appropriate experimental approaches.

The measurement of metabolic rates is central to important questions in many areas of physiological research. Unfortunately these measurements are anything but straightforward, with numerous pitfalls awaiting both the novice and even the experienced investigator. The original edition of this work, published in 2008, quickly became the principle "how to" manual for the field. It successfully de-mystified the topic, explaining every common variation of metabolic rate measurement. Background information on different analyzer and equipment types allowed users to choose the best instruments for their application. Respirometry equations, normally a topic of terror and confusion to researchers, were derived and described in sufficient detail to facilitate their selection and use. In this new edition, the content has been thoroughly updated and a decade of new literature incorporated. New chapters on room calorimetry, human metabolic measurement, and metabolic phenotyping have also been added. Measuring Metabolic Rates is aimed at experimental biologists, physiologists, and any professional scientist involved with metabolic measurement. This practical handbook will also be of relevance and use to graduate students.

The flock of greylag geese established by Konrad Lorenz in Austria in 1973 has become an influential model animal system and one of the few worldwide with complete life-history data spanning several decades. Based on the unique records of nearly 1000 free-living greylag geese, this is a synthesis of more than twenty years of behavioural research. It provides a comprehensive overview of a complex bird society, placing it in an evolutionary framework and drawing on a range of approaches, including behavioural (personality, aggression, pair bonding and clan formation), physiological, cognitive and genetic. With contributions from leading researchers, the chapters provide valuable insight into historic and recent research on the social behaviour of geese. All aspects of goose and bird sociality are discussed in the context of parallels with mammalian social organisation, making this a fascinating resource for anyone interested in integrative approaches to vertebrate social systems.

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.

The second edition of "Tigers of the World" explores tiger biology, ecology, conservation, management, and the science and technology that make this possible. In 1988, when the first edition was published, tiger conservation was still in its infancy, and two decades later there has been a revolution not only in what is known, but how information about tigers is obtained and disseminated. In the fast changing world of conservation, there is a great need to summarize the vast and current state-of-the-art, to put this into historical perspective, and to speculate in what yet remains to be done. "Tigers of the World, 2e" fulfills this need by bringing together in a unique way the world s leading tiger experts into one volume. Despite the challenges ahead, there are bright spots in this story and lessons aplenty not only for tiger specialists but large carnivore specialists, conservation biologists, wildlife managers, natural resource policymakers, and most importantly the caring public.

*Examines the past twenty years of research from the world s leading tiger expertson biology, politics, and conservation.

*Describes latest methods used to disseminate and obtaininformation needed for conservation and care of this species.

*Includes coverage on genetics and ecology, policy, poaching and trade, captive breeding and farming, and the status of Asia s last wild tigers.

*Excellent resource for grad courses in conservation biology, wildlife management, and veterinary programs.

*New volume continues the classic Noyes Series in Animal Behavior, Ecology, Conservation and Management. "

John James Audubon's The Birds of America stands as an unparalleled achievement in American art, a huge book that puts nature dramatically on the page. With that work, Audubon became one of the most adulated artists of his time, and America's first celebrity scientist. In this fresh approach to Audubon's art and science, Gregory Nobles shows us that Audubon's greatest creation was himself. A self-made man incessantly striving to secure his place in American society, Audubon made himself into a skilled painter, a successful entrepreneur, and a prolific writer, whose words went well beyond birds and scientific description. He sought status with the "gentlemen of science" on both sides of the Atlantic, but he also embraced the ornithology of ordinary people. In pursuit of popular acclaim in art and science, Audubon crafted an expressive, audacious, and decidedly masculine identity as the "American Woodsman," a larger-than-life symbol of the new nation, a role he perfected in his quest for transatlantic fame. Audubon didn't just live his life; he performed it. In exploring that performance, Nobles pays special attention to Audubon's stories, some of which-the murky circumstances of his birth, a Kentucky hunting trip with Daniel Boone, an armed encounter with a runaway slave-Audubon embellished with evasions and outright lies. Nobles argues that we cannot take all of Audubon's stories literally, but we must take them seriously. By doing so, we come to terms with the central irony of Audubon's true nature: the man who took so much time and trouble to depict birds so accurately left us a bold but deceptive picture of himself.

This is the essential new field guide to the birds of Chile. Representing a great diversity of habitats, from the Andes in the north down to the tundra and sub-Antarctic rainforest of Tierra del Fuego in the far south, Chile is the breeding ground or temporary abode of 473 known species including 9 found nowhere else in the world. "Birds of Chile" covers them all, embracing not only the mainland but points offshore such as Easter Island as well as the Antarctic Peninsula and adjacent islands, plus the Falklands and South Georgia. In addition to being a friendly and fruitful birding destination in its own right, Chile is the starting point for many Antarctic cruises.

Succinct, identification-focused text and distribution maps share a page opposite each of the 97 color plates to allow quick and easy reference. Between the boldfaced English name and the scientific name comes the Spanish name as used in Chile; this is important, for birders will find their quest far more enjoyable and effectual if they can explain to Chileans exactly what they are looking at, think they are looking at, or hope to be looking at.

Since Chile's list of resident species is yet far from conclusive, vagrants and rarities are also included. Indeed, some birds once thought to be accidentals in Chile have since proved to be regulars, including the Westland Petrel, Least Sandpiper, Cliff Swallow, and Golden-billed Saltator. Compact, comprehensive, and easy to use, Birds of Chile is the essential field guide to the birds of this spectacular and tourist-friendly country. The essential new field guide to the birds of Chile97 color plates with succinct text and maps on facing pages for quick reference and easy identificationAll 473 known species breeding in or visiting Chile, from the Andes in the north down to the tundra and sub-Antarctic rainforest of Tierra del Fuego in the southAlso covers points offshore such as Easter Island as well as the Antarctic Peninsula and adjacent islands, plus the Falklands and South GeorgiaCompact, portable, and user-friendly

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.

A photographic celebration of the return of otters to our rivers and freshwater wetlands after a drastic decline. Ripples of excitement are spreading through Europe's rivers and wetlands. A generation ago, otter watching was a wildlife highlight restricted to remote coastal areas - otter populations had been decimated over the previous century by pesticide poisoning and habitat disturbance. Now we are seeing the positive effect of determined conservation efforts over recent decades. As our waterways improve, otters are returning and spreading throughout their former habitats. One of the UK's leading natural history photographers, Laurie Campbell got to know otters while working in Scotland's Highlands and Islands, but he had never seen these elusive predators on his home beat. Then, in the early 1990s, he was delighted to find otters back on the Tweed and its tributaries, a river system he has lived close to for most of his life. The discovery launched him on a quest to create a photographic account of their lives on his home river. More than two decades later, otter numbers continue to increase, and new generations of otters have become more confident around people, sometimes appearing in broad daylight and in town centres. Laurie continues his long-standing study, still photographing the otters through the changing seasons - always with an eye on the bigger picture of the river itself and the plants and animals that share the otters' habitat. Wildlife journalist and writer Anna Levin accompanies Laurie to the riverbank and learns of his working philosophy and fieldcraft. Together they weave a wealth of information into the stories that the pictures tell. While extracts from Anna's notebooks offer a vivid glimpse of the photographer at work and the otters that enchant them both.

Bird song is one of the most remarkable and impressive sounds in the natural world, and has inspired not only students of natural history, but also great writers, poets and composers. Extensively updated from the first edition, the main thrust of this book is to suggest that the two main functions of song are attracting a mate and defending territory. It shows how this evolutionary pressure has led to the amazing variety and complexity we see in the songs of different species throughout the world. Writing primarily for students and researchers in animal behavior, the authors review over 1000 scientific papers and reveal how scientists are beginning to unravel and understand how and why birds communicate with the elaborate vocalizations we call song. Highly illustrated throughout and written in straightforward language, Bird Song also holds appeal for amateur ornithologists with some knowledge of biology.
