    It is the most comprehensive one-volume guide to the Neotropics available today. Widely praised in its first edition, it remains a book of unparalleled value to tourists, students, and scientists alike. This second edition has been substantially revised and expanded to incorporate the abundance of new scientific information that has been produced since it was first published in 1989. Major additions have been made to every chapter, and new chapters have been added on Neotropical ecosystems, human ecology, and the effects of deforestation. Biodiversity and its preservation are discussed throughout the book, and Neotropical evolution is described in detail. This new edition offers all new drawings and photographs, many of them in color. As enthusiastic readers of the first edition will attest, this is a charming book. Wearing his learning lightly and writing with ease and humor, John Kricher presents the complexities of tropical ecology as accessible and nonintimidating. Kricher is so thoroughly knowledgeable and the book is so complete in its coverage that general readers and ecotourists will not need any other book to help them identify and understand the plants and animals, from birds to bugs, that they will encounter in their travels to the New World tropics. At the same time, it will fascinate armchair travelers and students who may get no closer to the Neotropics than this engagingly written book.

    Now she builds on those insights to show us how to give our animals the best and happiest life—on their terms, not ours.It’s usually easy to pinpoint the cause of physical pain in animals, but to know what is causing them emotional distress is much harder. rawing on the latest research and her own work,Grandin identifies the core emotional needs of animals.

    A manhunt. The triumph of justice and of the wolf.The greatest event in Yellowstone history. Greater Yellowstone was the last great truly intact ecosystem in the temperate zones of the earth—until, in the 1920s, U.S. government agents exterminated its top predator, the gray wolf. With traps and rifles, even torching pups in their dens, the killing campaign was entirely successful. The howl of the “evil” wolf was heard no more. The “good” animals—elk, deer, bison—proliferated, until they too had to be “managed.” Two decades later, recognizing that ecosystems lacking their keystone predators tend to unravel, the visionary naturalist Aldo Leopold called for the return of the wolf to Yellowstone. It would take another fifty years for his vision to come true. In the early 1990s, as the movement for Yellowstone wolf restoration gained momentum, rage against it grew apace. When at last, in February 1995, fifteen wolves were trapped in Alberta and brought to acclimation pens in Yellowstone, even then legal and political challenges continued. There was also a lot of talk in the bars about “shoot, shovel, and shut up.” While the wolves’ enemies worked to return them to Canada, the biologists in charge of the project feared that the wolves might well return on their own. Once they were released, two packs remained in the national park, but one bore only one pup and the other none. The other, comprising Wolves Nine and Ten and Nine’s yearling daughter, disappeared. They were in fact heading home. As they emerged from protected federal land, an unemployed ne’er-do-well from Red Lodge, Montana, trained a high-powered rifle on Wolf Number Ten and shot him through the chest. Number Nine dug a den next to the body of her mate, and gave birth to eight pups. The story of their rescue and the manhunt for the killer is the heart of The Killing of Wolf Number Ten. + Read this book, and if you are ever fortunate enough to hear the howling of Yellowstone wolves, you will always think of Wolves Nine and Ten. If you ever see a Yellowstone wolf, chance are it will be carrying their DNA. The restoration of the wolf to Yellowstone is now recognized as one of conservation’s greatest achievements, and Wolves Nine and Ten will always be known as its emblematic heroes.

    Illustrated with hundreds of his original photographs, Tracking & the Art of Seeing provides complete information on the behavior and habitat of over 50 animal species and shows you how to identify animals by their tracks, tail patterns, droppings, dens, scratches and other signs.

    Darwin wondered why these birds were confined to remote islands at the tip of South America, sensing a larger story, but he set this mystery aside and never returned to it. Almost two hundred years later, Jonathan Meiburg takes up this chase. He takes us through South America, from the fog-bound coasts of Tierra del Fuego to the tropical forests of Guyana, in search of these birds: striated caracaras, which still exist, though they're very rare. He reveals the wild, fascinating story of their history, origins, and possible futures. And along the way, he draws us into the life and work of William Henry Hudson, the Victorian writer and naturalist who championed caracaras as an unsung wonder of the natural world, and to falconry parks in the English countryside, where captive caracaras perform incredible feats of memory and problem-solving. A Most Remarkable Creature is a hybrid of science writing, travelogue, and biography, as generous and accessible as it is sophisticated, and absolutely riveting.

    Legendary marine scientist Sylvia Earle portrays a planet teetering on the brink of irreversible environmental crisis.In recent decades we’ve learned more about the ocean than in all previous human history combined. But, even as our knowledge has exploded, so too has our power to upset the delicate balance of this complex organism. Modern overexploitation has driven many species to the verge of extinction, from tiny but indispensable biota to magnificent creatures like tuna, swordfish, and great whales. Since the mid-20th century about half our coral reefs have died or suffered sharp decline; hundreds of oxygen-deprived "dead zones" blight our coastal waters; and toxic pollutants afflict every level of the food chain.Fortunately, there is reason for hope, but what we do—or fail to do—in the next ten years may well resonate for the next ten thousand. The ultimate goal, Earle argues passionately and persuasively, is to find responsible, renewable strategies that safeguard the natural systems that sustain us. The first step is to understand and act upon the wise message of this accessible, insightful, and compelling book.

    The descriptive text includes information on size, geological period, geographical distribution, and ecology of the animal or plant before it was fossilized. In addition, the book provides lists of Geological Survey offices and major fossil collections, a geological time chart, and a guide to collecting and preserving fossils.

    Taking as territory everything from the Big Bang to the rise of civilization, Bryson seeks to understand how we got from there being nothing at all to there being us. To that end, he has attached himself to a host of the world’s most advanced (and often obsessed) archaeologists, anthropologists, and mathematicians, travelling to their offices, laboratories, and field camps. He has read (or tried to read) their books, pestered them with questions, apprenticed himself to their powerful minds. A Short History of Nearly Everything is the record of this quest, and it is a sometimes profound, sometimes funny, and always supremely clear and entertaining adventure in the realms of human knowledge, as only Bill Bryson can render it. Science has never been more involving or entertaining.

    And the first step is to start looking after the insects, the little creatures that make our shared world go round. Insects are essential for life as we know it. As they become scarcer, our world will slowly grind to a halt; we simply cannot function without them. Drawing on the latest ground-breaking research and a lifetime's study, Dave Goulson reveals the shocking decline of insect populations that has taken place in recent decades, with potentially catastrophic consequences. He passionately argues that we must all learn to love, respect, and care for our six-legged friends. Eye-opening, inspiring, and riveting, Silent Earth is part love letter to the insect world, part elegy, part rousing manifesto for a greener planet. It is a call to arms for profound change at every level--in government policy, agriculture, industry, and in our own homes and gardens. Although time is running out, it is not too late for insect populations to recover. We may feel helpless in the face of many of the environmental issues that loom on the horizon, but Goulson shows us how we can take simple steps to encourage insects and counter their destruction.

    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.

    While these are essential, many young ecologists need to figure out how to actually do research themselves. How to Do Ecology provides nuts-and-bolts advice on how to develop a successful thesis and research program. This book presents different approaches to posing testable ecological questions. In particular, it covers the uses, strengths, and limitations of manipulative experiments in ecology. It will help young ecologists consider meaningful treatments, controls, replication, independence, and randomization in experiments, as well as where to do experiments and how to organize a season of work. This book also presents strategies for analyzing natural patterns, the value of alternative hypotheses, and what to do with negative results.Science is only part of being a successful ecologist. This engagingly written book offers students advice on working with other people and navigating their way through the land mines of research. Findings that don't get communicated are of little value. How to Do Ecology suggests effective ways to communicate information in the form of journal articles, oral presentations, and posters. Finally, it outlines strategies for developing successful grant and research proposals. Numerous checklists, figures, and boxes throughout the book summarize and reinforce the main points. In short, this book makes explicit many of the unspoken assumptions behind doing good research in ecology, and provides an invaluable resource for meaningful conversations among ecologists.
