The Arizona Breeding Bird Atlas (Hardcover, New): Troy Corman, Cathryn Wise-Gervais The Arizona Breeding Bird Atlas (Hardcover, New)
Troy Corman, Cathryn Wise-Gervais
R1,916 R1,733 Discovery Miles 17 330 Save R183 (10%) Shipped within 7 - 12 working days

This book is the capstone of the first comprehensive state-wide survey of Arizona's breeding birds. More than 700 surveyors, mainly volunteers, reported a total of 376 bird species during the 1993-2000 field seasons. Of those species, 283 were confirmed as breeding and 18 additional species were suspected of potentially nesting in the state during the atlas survey period. The atlas provides a breeding distribution snapshot for each of Arizona's nesting bird species at the end of the twentieth century. Bird populations change constantly due to environmental factors and human activities. The data compiled in this book will serve as a baseline against which to judge future changes. It also provides a wealth of natural history information. Each of the 270 two-page species accounts contains a colour photograph of the species and a range map summarising the breeding distribution records collected during the atlas survey period. The accompanying descriptive text and graphs provide nesting habitat information and a timeline chronicling each bird's breeding habits and migratory status in Arizona. Additional chapters describe atlas methods, results, and Arizona ornithological history, as well as topography, climate, and habitat diversity, which ultimately govern bird species distribution in the state. Useful to land managers and biologists, the atlas will also be a resource for birders and educators and will increase public awareness of Arizona's vast avian life.

Ten Thousand Birds - Ornithology since Darwin (Hardcover): Tim Birkhead, Jo Wimpenny, Bob Montgomerie Ten Thousand Birds - Ornithology since Darwin (Hardcover)

R899 R668 Discovery Miles 6 680 Save R231 (26%) Shipped within 7 - 11 working days

"Ten Thousand Birds" provides a thoroughly engaging and authoritative history of modern ornithology, tracing how the study of birds has been shaped by a succession of visionary and often-controversial personalities, and by the unique social and scientific contexts in which these extraordinary individuals worked. This beautifully illustrated book opens in the middle of the nineteenth century when ornithology was a museum-based discipline focused almost exclusively on the anatomy, taxonomy, and classification of dead birds. It describes how in the early 1900s pioneering individuals such as Erwin Stresemann, Ernst Mayr, and Julian Huxley recognized the importance of studying live birds in the field, and how this shift thrust ornithology into the mainstream of the biological sciences. The book tells the stories of eccentrics like Colonel Richard Meinertzhagen, a pathological liar who stole specimens from museums and quite likely murdered his wife, and describes the breathtaking insights and discoveries of ambitious and influential figures such as David Lack, Niko Tinbergen, Robert MacArthur, and others who through their studies of birds transformed entire fields of biology.

"Ten Thousand Birds" brings this history vividly to life through the work and achievements of those who advanced the field. Drawing on a wealth of archival material and in-depth interviews, this fascinating book reveals how research on birds has contributed more to our understanding of animal biology than the study of just about any other group of organisms.

An accessible and richly illustrated introduction to the natural history of dogs--from evolution, anatomy, cognition, and behavior to the relationship between dogs and humans As one of the oldest domesticated species, selectively bred over millennia to possess specific behaviors and physical characteristics, the dog enjoys a unique relationship with humans. More than any other animal, dogs are attuned to human behavior and emotions, and accordingly play a range of roles in society, from police and military work to sensory and emotional support. Selective breeding has led to the development of more than three hundred breeds that, despite vast differences, still belong to a single species, Canis familiaris. The Dog is an accessible, richly illustrated, and comprehensive introduction to the fascinating natural history and scientific understanding of this beloved species. d m Mikl si, a leading authority on dogs, provides an appealing overview of dogs' evolution and ecology; anatomy and biology; behavior and society; sensing, thinking, and personality; and connections to humans. Illustrated with some 250 color photographs, The Dog begins with an introductory overview followed by an exploration of the dog's prehistoric origins, including current research about where and when canine domestication first began. The book proceeds to examine dogs' biology and behavior, paying particular attention to the physiological and psychological aspects of the ways dogs see, hear, and smell, and how they communicate with other dogs and with humans. The book also describes how dogs learn about their physical and social environments and the ways they form attachments to humans. The book ends with a section showcasing a select number of dog breeds to illustrate their amazing physical variety. Beautifully designed and filled with surprising facts and insights, this book will delight anyone who loves dogs and wants to understand them better.

R1,010 Discovery Miles 10 100 Shipped within 7 - 12 working days

Understanding the complex relationships between humans and the natural world is essential for achieving environmental sustainability and improving human well-being, yet many studies are unable to reveal complex interactions and hidden trends. This is the first book to synthesize the findings and approaches of long-term integrated research in a model coupled human and natural system, and to illustrate their applications to regional, national, and global scales. It features a classic long-term interdisciplinary research project in the Wolong Nature Reserve of China, which contains one of the largest wild populations of the world-famous endangered giant pandas. Bringing together a team of contributors from both the natural and social sciences, this book explores how a long-term interdisciplinary and model system approach is essential to uncover the common patterns and mechanisms of coupled systems, to develop ideas and methods for studying and managing other coupled systems, and ultimately to contribute to the development of theories about coupled systems for sustainability. Pandas and People will be essential reading for scholars interested in the interface of the natural and social sciences, including ecologists, conservation biologists, environmental scientists, sustainability scientists, wildlife biologists, forest scientists, sociologists, anthropologists, economists, and political scientists. It will also be a valuable reference for policy makers, natural resource managers, and graduate students.

Did you know that a groundhog is really a type of squirrel? That squirrels control their body temperature with their tails? That most squirrels have yellow-tinted eye lenses that work like sunglasses to reduce glare? That tree squirrels can turn their hind feet completely around when climbing down a tree head-first? In Squirrels: The Animal Answer Guide, Richard W. Thorington Jr. and Katie Ferrell unveil the fascinating world of one of the "most watched" mammals on the planet. The diversity of squirrels is astounding. There are 278 species that inhabit all continents except Antarctica and Australia-varying in size from the lumbering 18-pound gray marmot to the graceful pygmy flying squirrel that is smaller than most mice. In many parts of the world they readily share human habitats, joining us for lunch in a city park, raiding our bird feeders, and sneaking into college dorm rooms through open windows. Reviled as pests or loved as an endearing amusement, squirrels have played important roles in trade, literature, and mythology. Thorington and Ferrell cover every aspect of this diverse animal family, from the first squirrels of 36 million years ago to the present day. With over one hundred photographs and an intuitive question-and-answer format, this authoritative and engaging guide sheds light on a common mammal that is anything but commonplace.

R1,085 Discovery Miles 10 850 Shipped within 7 - 12 working days

The musteloids are the most diverse super-family among carnivores, ranging from little known, exotic, and highly-endangered species to the popular and familiar, and include a large number of introduced invasives. They feature terrestrial, fossorial, arboreal, and aquatic members, ranging from tenacious predators to frugivorous omnivores, span weights from a 100g weasel to 30kg giant otters, and express a range of social behaviours from the highly gregarious to the fiercely solitary. Musteloids are the subjects of extensive cutting-edge research from phylogenetics to the evolution of sociality and through to the practical implications of disease epidemiology, introduced species management, and climate change. Their diversity and extensive biogeography inform a wide spectrum of ecological theory and conservation practice. The editors of this book have used their combined 90 years of experience working on the behaviour and ecology of wild musteloids to draw together a unique network of the world's most successful and knowledgeable experts. The book begins with nine review chapters covering hot topics in musteloid biology including evolution, disease, social communication, and management. These are followed by twenty extensive case studies providing a range of comprehensive geographic and taxonomic coverage. The final chapter synthesises what has been discussed in the book, and reflects on the different and diverse conservation needs of musteloids and the wealth of conservation lessons they offer. Biology and Conservation of Musteloids provides a conceptual framework for future research and applied conservation management that is suitable for graduate level students as well as professional researchers in musteloid and carnivore ecology and conservation biology. It will also be of relevance and use to conservationists and wildlife managers.

Raptors are an unusual success story of wildness thriving in the heart of our cities--they have developed substantial populations around the world in recent decades. But there are deeper issues around how these birds make their urban homes. New research provides insight into the role of raptors as vital members of the urban ecosystem and future opportunities for protection, management, and environmental education. A cutting-edge synthesis of over two decades of scientific research, Urban Raptors is the first book to offer a complete overview of urban ecosystems in the context of bird-of-prey ecology and conservation. This comprehensive volume examines urban environments, explains why some species adapt to urban areas but others do not, and introduces modern research tools to help in the study of urban raptors. It also delves into climate change adaptation, human-wildlife conflict, and the unique risks birds of prey face in urban areas before concluding with real-world wildlife management case studies and suggestions for future research and conservation efforts. Boal and Dykstra have compiled the go-to single source of information on urban birds of prey. Among researchers, urban green space planners, wildlife management agencies, birders, and informed citizens alike, Urban Raptors will foster a greater understanding of birds of prey and an increased willingness to accommodate them as important members, not intruders, of our cities.

The foraging mode of lizards has been a central theme in guiding research in lizard biology for three decades. Foraging mode has been shown to be a pervasive evolutionary force molding the diet, ecology, behavior, anatomy, biomechanics, life history and physiology of lizards. This volume reviews the state of our knowledge on the effects of foraging mode on these and other organismal systems to show how they have evolved, over a wide taxonomic survey of lizard groups. The reviews presented here reveal the continuous nature of foraging strategies in lizards and snakes, providing the reader with an up-to-date review of the field, and will equip researchers with new insights and future directions for the sit-and-wait vs. wide foraging paradigm. This will serve as a reference book for herpetologists, evolutionary biologists, ecologists and animal behaviorists.

Throughout our history, humans have been captivated by mythic beasts and legendary creatures. Tales of Bigfoot, the Yeti, and the Loch Ness monster are part of our collective experience. Now comes a book from two dedicated investigators that explores and elucidates the fascinating world of cryptozoology. Daniel Loxton and Donald R. Prothero have written an entertaining, educational, and definitive text on cryptids, presenting the arguments both for and against their existence and systematically challenging the pseudoscience that perpetuates their myths. After examining the nature of science and pseudoscience and their relation to cryptozoology, Loxton and Prothero take on Bigfoot; the Yeti, or Abominable Snowman, and its cross-cultural incarnations; the Loch Ness monster and its highly publicized sightings; the evolution of the Great Sea Serpent; and Mokele Mbembe, or the Congo dinosaur. They conclude with an analysis of the psychology behind the persistent belief in paranormal phenomena, identifying the major players in cryptozoology, discussing the character of its subculture, and considering the challenge it poses to clear and critical thinking in our increasingly complex world.

A small set of fossilized bones discovered almost thirty years ago led paleontologist Sankar Chatterjee on a lifelong quest to understand their place in our understanding of the history of life. They were clearly the bones of something unusual, a bird-like creature that lived long, long ago in the age of dinosaurs. He called it Protoavis, and the animal that owned these bones quickly became a contender for the title of "oldest known bird." In 1997, Chatterjee published his findings in the first edition of The Rise of Birds. Since then Chatterjee and his colleagues have searched the world for more transitional bird fossils. And they have found them. This second edition of The Rise of Birds brings together a treasure trove of fossils that tell us far more about the evolution of birds than we once dreamed possible. With no blind allegiance to what he once thought he knew, Chatterjee devours the new evidence and lays out the most compelling version of the birth and evolution of the avian form ever attempted. He takes us from Texas to Spain, China, Mongolia, Madagascar, Australia, Antarctica, and Argentina. He shows how, in the "Cretaceous Pompeii" of China, he was able to reconstruct the origin and evolution of flight of early birds from the feathered dinosaurs that lay among thousands of other amazing fossils. Chatterjee takes us to where long-hidden bird fossils dwell. His compelling, occasionally controversial, revelations-accompanied by spectacular illustrations-are a must-read for anyone with a serious interest in the evolution of "the feathered dinosaurs," from vertebrate paleontologists and ornithologists to naturalists and birders.

A comprehensive natural history of nature's smallest bird species. "The spectacular photography of Michael and Patricia Fogden reveals the diversity, beautiful colours and movement of these unique birds." Publishers Weekly. The tiny hummingbird has long been a source of fascination for birdwatchers and naturalists alike. They number 300 species and Ronald Orenstein has a passion for all of them. Hummingbirds are the smallest birds in the world. A hummingbird egg is the size of a pea, barely, and the chick that emerges will be smaller than a penny, if that. But these tiny birds pack a powerful engine: a hummingbird's heart beats more than 1,200 times per minute. Nicknamed the "avian helicopter," a hummingbird's wings beat from 70 times per second in direct flight, to more than 200 times per second when diving. Not surprisingly, that whirlwind of wing power creates a humming sound. To fuel such energy, hummingbirds must eat as much as eight times their body weight on a daily basis, which means visiting an average of 1,000 flowers - every day - to get enough nectar. Hummingbirds are found in North, Central and South America, with the greatest number in Ecuador, although some species breed as far north as Canada. Most species migrate from Mexico to Alaska, a distance of more than 5,000 miles. In this book Orenstein covers all aspects of hummingbird natural history, their relationship with the plants on which they feed, the miracle of their flight, their elaborate social life and nesting behaviour, and their renowned feats of migration. More than 170 colour photographs of these magnificent creatures, taken in the wild, adorn the pages of Hummingbirds. Ornithologists and natural history readers alike will gain new insight into the tiny bird and revel in the stunning images.
