Highly intelligent and adaptable, they hunt and play together in close-knit packs, sometimes roaming over hundreds of square miles in search of food. Once teetering on the brink of extinction across much of the United States and Europe, wolves have made a tremendous comeback in recent years, thanks to legal protection, changing human attitudes, and efforts to reintroduce them to suitable habitats in North America.As wolf populations have rebounded, scientific studies of them have also flourished. But there hasn't been a systematic, comprehensive overview of wolf biology since 1970. In Wolves, many of the world's leading wolf experts provide state-of-the-art coverage of just about everything you could want to know about these fascinating creatures. Individual chapters cover wolf social ecology, behavior, communication, feeding habits and hunting techniques, population dynamics, physiology and pathology, molecular genetics, evolution and taxonomy, interactions with nonhuman animals such as bears and coyotes, reintroduction, interactions with humans, and conservation and recovery efforts. The book discusses both gray and red wolves in detail and includes information about wolves around the world, from the United States and Canada to Italy, Romania, Saudi Arabia, Israel, India, and Mongolia. Wolves is also extensively illustrated with black and white photos, line drawings, maps, and fifty color plates.Unrivalled in scope and comprehensiveness, Wolves will become the definitive resource on these extraordinary animals for scientists and amateurs alike. “An excellent compilation of current knowledge, with contributions from all the main players in wolf research. . . . It is designed for a wide readership, and certainly the language and style will appeal to both scientists and lucophiles alike. . . . This is an excellent summary of current knowledge and will remain the standard reference work for a long time to come.”—Stephen Harris, New Scientist “This is the place to find almost any fact you want about wolves.”—Stephen Mills, BBC Wildlife Magazine

    A concise atlas of anatomy, it contains more than 200 specially prepared accurate and clear drawings that include material never illustrated before. The text is as informative as the drawings; written at a level appropriate to undergraduate students and to bird lovers in general, it discusses why birds look and act the way they do.Designed to supplement a basic ornithology textbook, the Manual of Ornithology covers systematics and evolution, topography, feathers and flight, the skeleton and musculature, and the digestive, circulatory, respiratory, excretory, reproductive, sensory, and nervous systems of birds, as well as field techniques for watching and studying birds. Each chapter concludes with a list of key references for the topic covered, with a comprehensive bibliography at the end of the volume. The book will be a guide and reference for every level of bird study—a basic tool for investigation for anyone curious about the fascinating world of birds.

    Includes: A key to insect groups. Mature and immature forms. How insects grow and develop and what they eatHow to find and observe them.Full color pictures, nontechnical language, and up-to-date range maps make this a gem of a guide for beginners at any age.

    Fully grown they can measure 10 feet and weigh close to 2,000 pounds, but at birth they are just 20 ounces. Creatures that may wander thousands of miles over the course of a year, they begin life in a snowdrift.Human encounters with these legendary beasts are cause for both excitement and apprehension. Tales throughout history describe the ferocity of polar bear attacks on humans; but human hunting of polar bears has exacted a far larger toll, obliging Arctic nations to try to protect their region’s iconic species before it’s too late.Now, however, another threat to the polar bears’ survival has emerged, one that is steadily removing sea ice and the life it supports. Without this habitat, polar bears cannot exist. The Great White Bear celebrates the story of this unique species. Through a blend of history, both natural and human, through myth and reality and observations both personal and scientific, Kieran Mulvaney masterfully provides a context for readers to consider the polar bear, its history, its life, and its uncertain fate.

    And unlike dogs, cats offer humans no practical benefit. The truth is they are sadly incompetent mouse-catchers and now pose a threat to many ecosystems. Yet, we love them still.Content:Catacombs Cat's cradle What's the catch? The cats that ate the canaries The cat lobby CAT scan Pandora's litter box Lions and toygers and lykoi Nine likes.

    Accompanying every species entry is a distribution map and illustrations showing the species in all the major plumages (male, female, immature, in flight, at rest, feeding: whatever is important).In addition, each group of birds includes an introduction which covers the major problems involved in identifying or observing them: how to organise a sea watching trip, how to separate birds of prey in flight, which duck hybrids can be confused with which main species. These and many other common birdwatching questions are answered.The combination of definitive text, up-to-date distribution maps and superb illustrations, all in a single volume, makes this book the ultimate field guide, essential on every bookshelf and birdwatching trip.

    Illustrated throughout, this handbook of birds covers the most common British and European birds in detail.

    The Birder's Handbook is the first of its kind: a portable library of fascinating information not included in your identification guide. For each of the 646 species of birds that breed in North America, The Birder's Handbook will tell you at a glance: * Where the bird nests, and which sex(es) build(s) the nest;* How many eggs the bird lays, what they look like, which patent incubates and for how long, and how the young are cared for;* Food preferences and foraging habits.You will also find information about displays and mating, wintering, conservation status, and much more. In addition, The Birder's Handbook contains some 250 short essays covering all aspects of avian natural history.

    Descriptive text includes measurements, diagnostic details, and information on habitat, range, feeding habits, sounds or songs, flight period, web construction, life cycle, behaviors, folklore, and environmental impact. An illustrated key to the insect orders and detailed drawings of the parts of insects, spiders, and butterflies supplement this extensive coverage.

    Birds play a prominent role in attracting visitors, too. The shimmering quetzals, gaudy macaws, and comical toucans only begin to hint at the impressive avian diversity to be found throughout this small country."--from the Introduction This is the one field guide the novice or experienced birder needs to identify birds in the field in the diverse habitats found in Costa Rica. It features descriptions and illustrations of more than 820 resident and neotropical migrant species found in Costa Rica, all in a compact, portable, user-friendly design. The detailed full-color illustrations show identifying features--including plumage differences among males, females, and juveniles--and views of birds in flight wherever pertinent. Additional features of this all-new guide include: o 166 original color plates depicting more than 820 species. o Concise text that describes key field marks for positive identification, as well as habitat, behavior, and vocalizations. o Range maps and texts arranged on opposing pages from illustrations for quick, easy reference. o The most up-to-date bird list for Costa Rica. o A visual guide to the anatomical features of birds with accompanying explanatory text. o Quick reference to vultures and raptors in flight.

    Colorful and easy to use, this guide for the identification of shells includes general information on mollusks and advice on shell collecting and study.

    Featuring 50 common North American birds, such as the White-Breasted Butt Nugget and the Goddamned Canada Goose (or White-Breasted Nuthatch and Canada Goose for the layperson), Matt Kracht identifies all the idiots in your backyard and details exactly why they suck with ink drawings. Each entry is accompanied by facts about a bird's (annoying) call, its (dumb) migratory pattern, its (downright tacky) markings, and more.The essential guide to all things wings with migratory maps, tips for birding, musings on the avian population, and the ethics of birdwatching.

    Unlike their human counterparts, who must alter their environment to accommodate our physical limitations, animals are adaptable to an amazing range of conditions--i.e., radical changes in a creature's physiology take place to match the demands of the environment. Winter provides an especially remarkable situation, because of how drastically it affects the most elemental component of all life: water.Examining everything from food sources in the extremely barren winter landscape to the chemical composition that allows certain creatures to survive, Heinrich's Winter World awakens the largely undiscovered mysteries by which nature sustains herself through the harsh, cruel exigencies of winters

    Her fascinating and wide-ranging work provides clear explanations of the science surrounding keystone predators and considers how this notion can help provide practical solutions for restoring ecosystem health and functioning.Eisenberg examines both general concepts and specific issues, sharing accounts from her own fieldwork to illustrate and bring to life the ideas she presents. She considers how resource managers can use knowledge about trophic cascades to guide recovery efforts, including how this science can be applied to move forward the bold vision of rewilding the North American continent. In the end, the author provides her own recommendations for local and landscape-scale applications of what has been learned about interactive food webs.At their most fundamental level, trophic cascades are powerful stories about ecosystem processes of predators and their prey, of what it takes to survive in a landscape, of the flow of nutrients. The Wolf’s Tooth is the first book to focus on the vital connection between trophic cascades and restoring biodiversity and habitats, and to do so in a way that is accessible to a diverse readership.

    Today there are three cats for every dog on the planet, and yet cats remain more mysterious, even to their most adoring owners. Unlike dogs, cats evolved as solitary hunters, and, while many have learned to live alongside humans and even feel affection for us, they still don’t quite get us” the way dogs do, and perhaps they never will. But cats have rich emotional lives that we need to respect and understand if they are to thrive in our company.In Cat Sense, renowned anthrozoologist John Bradshaw takes us further into the mind of the domestic cat than ever before, using cutting-edge scientific research to dispel the myths and explain the true nature of our feline friends. Tracing the cat’s evolution from lone predator to domesticated companion, Bradshaw shows that although cats and humans have been living together for at least eight thousand years, cats remain independent, predatory, and wary of contact with their own kind, qualities that often clash with our modern lifestyles. Cats still have three out of four paws firmly planted in the wild, and within only a few generations can easily revert back to the independent way of life that was the exclusive preserve of their predecessors some 10,000 years ago. Cats are astonishingly flexible, and given the right environment they can adapt to a life of domesticity with their owners—but to continue do so, they will increasingly need our help. If we’re to live in harmony with our cats, Bradshaw explains, we first need to understand their inherited quirks: understanding their body language, keeping their environments—however small—sufficiently interesting, and becoming more proactive in managing both their natural hunting instincts and their relationships with other cats.A must-read for any cat lover, Cat Sense offers humane, penetrating insights about the domestic cat that challenge our most basic assumptions and promise to dramatically improve our pets’ lives—and ours.
