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.

    Whether you are a beginner, expert, or anywhere in between, The Crossley ID Guide will vastly improve your ability to identify birds.Unlike other guides, which provide isolated individual photographs or illustrations, this is the first book to feature large, lifelike scenes for each species. These scenes--640 in all--are composed from more than 10,000 of the author's images showing birds in a wide range of views--near and far, from different angles, in various plumages and behaviors, including flight, and in the habitat in which they live. These beautiful compositions show how a bird's appearance changes with distance, and give equal emphasis to characteristics experts use to identify birds: size, structure and shape, behavior, probability, and color. This is the first book to convey all of these features visually--in a single image--and to reinforce them with accurate, concise text. Each scene provides a wealth of detailed visual information that invites and rewards careful study, but the most important identification features can be grasped instantly by anyone.By making identification easier, more accurate, and more fun than ever before, The Crossley ID Guide will completely redefine how its users look at birds. Essential for all birders, it also promises to make new birders of many people who have despaired of using traditional guides.Revolutionary.

    In Dark Banquet, zoologist Bill Schutt takes readers on an entertaining voyage into the world of some of nature’s strangest creatures—the sanguivores. Using a sharp eye and mordant wit, Schutt makes a remarkably persuasive case that vampire bats, leeches, ticks, bed bugs, and other vampires are as deserving of our curiosity as warmer and fuzzier species are—and that many of them are even ­worthy of conservation.Schutt takes us from rural Trinidad to the jungles of Brazil to learn about some of the most reviled, misunderstood, and marvelously evolved animals on our planet: vampire bats. Only recently has fact begun to disentangle itself from fiction concerning these remarkable animals, and Schutt delves into the myths and misconceptions surrounding them. Examining the substance that sustains nature’s vampires, Schutt reveals just how little we actually knew about blood until well into the twentieth century. We revisit George Washington on his deathbed to learn how ideas about blood and the supposedly therapeutic value of bloodletting, first devised by the ancient Egyptians and Greeks, survived into relatively modern times. Schutt also tracks the history of medicinal leech use. Once employed by the tens of millions to drain perceived excesses of blood, today the market for these ancient creatures is booming once again—but for very different reasons.Among the other blood feeders we meet in these pages are bed bugs, or “ninja insects,” which are making a creepy resurgence in posh hotels and well-kept homes near you. In addition, Dark Banquet details our dangerous and sometimes deadly encounters with ticks, chiggers, and mites (the ­latter implicated in Colony Collapse Disorder—currently devastating honey bees worldwide). Then there are the truly weird—vampire finches. And if you thought piranha were scary, some people believe that the candiru (or willy fish) is the best reason to avoid swimming in the Amazon.Enlightening, alarming, and appealing to our delight in the bizarre, Dark Banquet peers into a part of the natural world to which we are, through our blood, inextricably linked.From the Hardcover edition.

    Thus, the literature on speciation, as well as the number of researchers and students working in this area, has grown explosively. Despite thesedevelopments, there has been no book-length treatment of speciation in many years. As a result, both the seasoned scholar and the newcomer to evolutionary biology had no ready guide to the recent literature on speciation--a body of work that is enormous, scattered, and increasingly technical.Although several excellent symposium volumes have recently appeared, these collections do not provide a unified, critical, and up-to-date overview of the field. Speciation is designed to fill this gap.Aimed at professional biologists, graduate students, and advanced undergraduates, Speciation covers both plants and animals (the first book on this subject to do so), and deals with all relevant areas of research, including biogeography, field work, systematics, theory, and genetic and molecularstudies. It gives special emphasis to topics that are either controversial or the subject of active research, including sympatric speciation, reinforcement, the role of hybridization in speciation, the search for genes causing reproductive isolation, and mounting evidence for the role of natural andsexual selection in the origin of species. The authors do not hesitate to take stands on these and other controversial issues. This critical and scholarly book will be invaluable to researchers in evolutionary biology and is also ideal for a graduate-level course on speciation.

    But it was not reels of wool or bales of cotton that awaited him, but plants and seeds…Over the next forty years, Bartram would send hundreds of American species to England, where Collinson was one of a handful of men who would foster a national obsession and change the gardens of Britain forever, introducing lustrous evergreens, fiery autumn foliage and colourful shrubs. They were men of wealth and taste but also of knowledge and experience like Philip Miller, author of the bestselling Gardeners Dictionary, and the Swede Carl Linnaeus, whose standardised botanical nomenclature popularised botany as a genteel pastime for the middle-classes; and the botanist-adventurer Joseph Banks and his colleague Daniel Solander who both explored the strange flora of Tahiti and Australia on the greatest voyage of discovery of modern times, Captain Cook’s Endeavour.This is the story of these men – friends, rivals, enemies, united by a passion for plants – whose correspondence, collaborations and squabbles make for a riveting human tale which is set against the backdrop of the emerging empire, the uncharted world beyond and London as the capital of science. From the scent of the exotic blooms in Tahiti and Botany Bay to the gardens at Chelsea and Kew, and from the sounds and colours of the streets of the City to the staggering vistas of the Appalachian mountains, The Brother Gardeners tells the story of how Britain became a nation of gardeners.

    This is the funny, poignant story of their two decades together.On Valentine's Day 1985, biologist Stacey O'Brien first met a four-day-old baby barn owl -- a fateful encounter that would turn into an astonishing 19-year saga. With nerve damage in one wing, the owlet's ability to fly was forever compromised, and he had no hope of surviving on his own in the wild. O'Brien, a young assistant in the owl laboratory at Caltech, was immediately smitten, promising to care for the helpless owlet and give him a permanent home. Wesley the Owl is the funny, poignant story of their dramatic two decades together. With both a tender heart and a scientist's eye, O'Brien studied Wesley's strange habits intensively and first-hand -- and provided a mice-only diet that required her to buy the rodents in bulk (28,000 over the owl's lifetime). As Wesley grew, she snapped photos of him at every stage like any proud parent, recording his life from a helpless ball of fuzz to a playful, clumsy adolescent to a gorgeous, gold-and-white, macho adult owl with a heart-shaped face and an outsize personality that belied his 18-inch stature. Stacey and Wesley's bond deepened as she discovered Wesley's individual personality, subtle emotions, and playful nature that could also turn fiercely loyal and protective -- though she could have done without Wesley's driving away her would-be human suitors! O'Brien also brings us inside the prestigious research community, a kind of scientific Hogwarts where resident owls sometimes flew freely from office to office and eccentric, brilliant scientists were extraordinarily committed to studying and helping animals; all of them were changed by the animal they loved. As O'Brien gets close to Wesley, she makes important discoveries about owl behavior, intelligence, and communication, coining the term "The Way of the Owl" to describe his inclinations: he did not tolerate lies, held her to her promises, and provided unconditional love, though he was not beyond an occasional sulk. When O'Brien develops her own life-threatening illness, the biologist who saved the life of a helpless baby bird is herself rescued from death by the insistent love and courage of this wild animal. Enhanced by wonderful photos, Wesley the Owl is a thoroughly engaging, heartwarming, often funny story of a complex, emotional, non-human being capable of reason, play, and, most important, love and loyalty. It is sure to be cherished by animal lovers everywhere.
