Few people know bears as intimately as Else Poulsen. She has raised bears, comforted bears, taught bears, learned from bears, had bears communicate their needs to her, and nursed bears back to health. This remarkable book reveals the many insights about bears and their lives that she has gained through her work with them. In the eighties, Poulsen became a zookeeper in Calgary, where she rehabilitated bears in crisis. She has shared in the joy of a polar bear discovering soil under her paws for the first time in twenty years, felt the pride of a cub learning to crack nuts with her molars, and grieved at the horror of captivity for Asian black bears in China.Smiling Bears provides an enlightening and moving portrait of bears in all their richness and complexity and of Poulsen's exhilarating work with them. Also available in paperback.

    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.

    Humans have feared them for centuries, long considering them the assassins and pariahs of the natural world.Now, in Venomous, the biologist Christie Wilcox investigates and illuminates the animals of our nightmares, arguing that they hold the keys to a deeper understanding of evolution, adaptation, and immunity. She reveals just how venoms function and what they do to the human body. With Wilcox as our guide, we encounter a jellyfish with tentacles covered in stinging cells that can kill humans in minutes; a two-inch caterpillar with toxic bristles that trigger hemorrhaging; and a stunning blue-ringed octopus capable of inducing total paralysis. How do these animals go about their deadly work? How did they develop such intricate, potent toxins? Wilcox takes us around the world and down to the cellular level to find out.Throughout her journey, Wilcox meets the intrepid scientists who risk their lives studying these lethal beasts, as well as “self-immunizers” who deliberately expose themselves to snakebites. Along the way, she puts her own life on the line, narrowly avoiding being envenomated herself. Drawing on her own research, Wilcox explains how venom scientists are untangling the mechanisms of some of our most devastating diseases, and reports on pharmacologists who are already exploiting venoms to produce lifesaving drugs. We discover that venomous creatures are in fact keystone species that play crucial roles in their ecosystems and ours—and for this alone, they ought to be protected and appreciated.Thrilling and surprising at every turn, Venomous will change everything you thought you knew about the planet’s most dangerous animals.

    But as animals can only be spied on by getting quite close Heinrich adopts ravens, thereby becoming a "raven father," as well as observing them in their natural habitat, studying their daily routines, and in the process painting a vivid picture of the world as lived by the ravens. At the heart of this book are Heinrich's love and respect for these complex and engaging creatures, and through his keen observation andanalysis, we become their intimates too.Throughout history there has existed an extraordinary relationship between humans and ravens. Ravens, like early humans, are scavengers on the kills of great carnivores. As scavengers, ravens were associated with hunters they found in the north: wolves and, later, men. The trinity of wolf, man, and raven in the hunt is an extremely ancient one. In considering the appeal of the raven, Bernd Heinrich suspects that a meeting of the minds might reside in that hunting trinity.Heinrich's passion for ravens has led him around the world in his research. Mind of the Raven takes you on an exotic journey--from New England to Germany, Montana to Baffin Island in the high Arctic--offering dazzling accounts of how science works in the field, filtered through the eyes of a passionate observer of nature.Heinrich has a true gift; through his stories, his beautiful writing, illustrations, and photography, the ravens come alive. Each new discovery and insight into their behavior is thrilling to read. just as the title promises, the reader is given a rare glimpse into the mind of these wonderful creatures.Following the dictum of Leonardo da Vinci--"It is not enough to believe what you see. YOU Must also understand what you see"--Bernd Heinrich enables us to see the natural world through the eyes of a scientist. At once lyrical and scientific, Mind of the Raven is bound to be a modern classic.

    Across North America, tens of thousands of people gather every spring and fall at more than one thousand known hawk migration sites--from New Jersey's Cape May to California's Golden Gate. Yet, as many discover, a standard field guide, with its emphasis on plumage, is often of little help in identifying those raptors soaring, gliding, or flapping far, far away.Hawks from Every Angle takes hawk identification to new heights. It offers a fresh approach that literally looks at the birds from every angle, compares and contrasts deceptively similar species, and provides the pictures (and words) needed for identification in the field. Jerry Liguori pinpoints innovative, field-tested identification traits for each species from the various angles that they are seen.Featuring 339 striking color photos on 68 color plates and 32 black & white photos, Hawks from Every Angle is unique in presenting a host of meticulously crafted pictures for each of the 19 species it covers in detail--the species most common to migration sites throughout the United States and Canada. All aspects of raptor identification are discussed, including plumage, shape, and flight style traits.For all birders who follow hawk migration and have found themselves wondering if the raptor in the sky matches the one in the guide, Hawks from Every Angle--distilling an expert's years of experience for the first time into a comprehensive array of truly useful photos and other pointers for each species--is quite simply a must.Key Features? The essential new approach to identifying hawks in flight Innovative, accurate, and field-tested identification traits for each species 339 color photos on 68 color plates, 32 black & white photos Compares and contrasts species easily confused with one another, and provides the pictures (and words) needed for identification in the field Covers in detail 19 species common to migration sites throughout the North America Discusses light conditions, how molt can alter the shape of a bird, aberrant plumages, and migration seasons and sites User-friendly format

    For the past several years, acclaimed Science reporter Jon Cohen has been following the DNA hunt, as well as eye-opening new studies in ape communication, human evolution, disease, diet, and more.In Almost Chimpanzee, Cohen invites us on a captivating scientific journey, taking us behind the scenes in cutting-edge genetics labs, rain forests in Uganda, sanctuaries in Iowa, experimental enclaves in Japan, even the Detroit Zoo. Along the way, he ferries fresh chimp sperm for a time-sensitive analysis, gets greeted by pant-hoots and chimp feces, and investigates an audacious attempt to breed a humanzee. Cohen offers a fresh and often frankly humorous insider's tour of the latest research, which promises to lead to everything from insights about the unique ways our bodies work to shedding light on stubborn human-only problems, ranging from infertility and asthma to speech disorders.And in the end, Cohen explains why it's time to move on from Jane Goodall's plea that we focus on how the two species are alike and turns to examining why our differences matter in vital ways—for understanding humans and for increasing the chances to save the endangered chimpanzee.
