Why do living things and physical phenomena take the forms they do? Analyzing the mathematical and physical aspects of biological processes, this historic work, first published in 1917, has become renowned as well for the poetry of is descriptions.

    With numerous black-and-white images and eight pages of color plates, The Lives of Ants provides a state-of-the-art look at what we now know about these fascinating creatures, portraying a world that is rich and full of surprises, one which, even after decades of observation, is still full of unsolved mysteries.The authors illuminate the world of the ant, shedding light on such topics as the ant's impressive abilities in direction finding and quite amazing ingenuity when it comes to building their nests, finding supplies, or exploiting other members of the animal kingdom. They show, too, that they are capable of aggression and violence, which can disturb the apparent peace of their colonies and embroil them in fratricidal or matricidal strife. Even their sexual arrangements are at times quite strange. In this area, as in many others, they display marked originality. Readers also discover that ants are walking bundles of secretory glands (they have about forty of them), which enable them to emit between ten and twenty different pheromones, each of which has its own "meaning." Some are produced by workers for recruiting their sisters or for alerting them to danger. Others are used for marking territory, for identifying members of their colony or conversely for detecting foreigners, and for indicating the location of food. In addition, ants can also emit sound signals, made of a high-pitched squeak, and they can even dance, though not as intricately or as well as bees.The Lives of Ants combines natural history with molecular biology, genetics, and even the latest developments in robotics, to explore the remarkable societies of ants, revealing the secrets of their mysterious lives.

Filled with amazing real-life stories of human/animal communication, The Language of Animals is a must for every animal enthusiast–and a loving gift to the engaging, expressive animals who have so much to share.

    In 1992, in a remote mountain range, a team of scientists discovered the remains of an unusual animal with exquisite long horns. It turned out to be a living species new to Western science -- a saola, the first large land mammal discovered in fifty years. Rare then and rarer now, a live saola had never been glimpsed by a Westerner in the wild when Pulitzer Prize finalist and nature writer William deBuys and conservation biologist William Robichaud set off to search for it in central Laos. Their team endured a punishing trek up and down white-water rivers and through mountainous terrain ribboned with the snare lines of armed poachers who roamed the forest, stripping it of wildlife. In the tradition of Bruce Chatwin, Colin Thubron, and Peter Matthiessen, The Last Unicorn chronicles deBuys's journey deep into one of the world's most remote places. It's a story rich with the joys and sorrows of an expedition into undiscovered country, pursuing a species as rare and elusive as the fabled unicorn. As is true with the quest for the unicorn, in the end the expedition becomes a search for something more: the essence of wildness in nature, evidence that the soul of a place can endure, and the transformative power of natural beauty.

    Thanks largely to YouTube clips posted by the sloth orphanage in Costa Rica, sloths have attracted a vast audience of admirers. Instead of seeing them as ridiculous anachronisms of which we know little, they have turned into creatures considered by many to be the most endearing on earth.Over much the same period, scientific investigations have also changed our view of sloths. No longer are they seen as total misfits in the modern world but, in the words of one specialist sloth investigator, they are 'masters of an alternative lifestyle'.In this wonderfully entertaining celebration of this most unique of creatures, William Hartston reveals the fascinating history of the sloth, from the prehistoric ground sloth to modern pygmy sloths in Panama, explores the current state of the science of sloths and reveals the truth behind sloth behaviour.

    Culled from the mud-spattered pages of her journal, this is her unvarnished account of her adventures and research.

    But when one evening at twilight a lone black wolf ambled into view not far from his doorstep, Nick would finally come to know this mystical species—up close as never before.A Wolf Called Romeo is the remarkable story of a wolf who returned again and again to interact with the people and dogs of Juneau, living on the edges of their community, engaging in an improbable, awe-inspiring interspecies dance and bringing the wild into sharp focus. At first the people of Juneau were guarded, torn between shoot first, ask questions later instincts and curiosity. But as Romeo began to tag along with cross-country skiers on their daily jaunts, play fetch with local dogs, or simply lie near Nick and nap under the sun, they came to accept Romeo, and he them. For Nick it was about trying to understand Romeo, then it was about winning his trust, and ultimately it was about watching over him, for as long as he or anyone could.Written with a deft hand and a searching heart, A Wolf Called Romeo is an unforgettable tale of a creature who defied nature and thus gave humans a chance to understand it a little more.

    Yet theirs is a world of intrepid hunter-explorers, eccentric naturalists, and gifted museum artisans, all devoted to the paradoxical pursuit of creating the illusion of life.Into this subculture of insanely passionate animal lovers ventures journalist Melissa Milgrom, whose journey stretches from the anachronistic family workshop of the last chief taxidermist for the American Museum of Natural History to the studio where an English sculptor, granddaughter of a surrealist artist, preserves the animals for Damien Hirst's most disturbing artworks. She wanders through Mr. Potter's Museum of Curiosities in the final days of its existence to watch dealers vie for preserved Victorian oddities, and visits the Smithsonian's offsite lab, where taxidermists transform zoo skins into vivacious beasts. She tags along with a Canadian bear trapper and former Roy Orbison impersonator--the three-time World Taxidermy Champion--as he resurrects an extinct Irish elk using DNA studies and Paleolithic cave art for reference; she even ultimately picks up a scalpel and stuffs her own squirrel. Transformed from a curious onlooker to an empathetic participant, Milgrom takes us deep into the world of taxidermy and reveals its uncanny appeal.
