Animals move with astounding grace, speed, and versatility: how do they do it, and what can we learn from them? In How to Walk on Water and Climb up Walls, David Hu takes readers on an accessible, wondrous journey into the world of animal motion. From basement labs at MIT to the rain forests of Panama, Hu shows how animals have adapted and evolved to traverse their environments, taking advantage of physical laws with results that are startling and ingenious. In turn, the latest discoveries about animal mechanics are inspiring scientists to invent robots and devices that move with similar elegance and efficiency.Hu follows scientists as they investigate a multitude of animal movements, from the undulations of sandfish and the way that dogs shake off water in fractions of a second to the seemingly crash-resistant characteristics of insect flight. Not limiting his exploration to individual organisms, Hu describes the ways animals enact swarm intelligence, such as when army ants cooperate and link their bodies to create bridges that span ravines. He also looks at what scientists learn from nature's unexpected feats--such as snakes that fly, mosquitoes that survive rainstorms, and dead fish that swim upstream. As researchers better understand such issues as energy, flexibility, and water repellency in animal movement, they are applying this knowledge to the development of cutting-edge technology.Integrating biology, engineering, physics, and robotics, How to Walk on Water and Climb up Walls demystifies the remarkable mechanics behind animal locomotion.

    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.

    In this extraordinary feat of nature writing, we meet ants who harvest crops, raise insects as livestock, build roadways and bridges, embark on nuptial flights, and make war.

    Its geology, its unique flora and fauna, and its striking role in human history intersect in surprising and dynamic ways. This book is the most wide-ranging and beautifully illustrated book available on the famous islands. Not since Darwin’s Naturalist’s Voyage has a book combined so much scientific and historic information with firsthand accounts that bring the Galápagos to life.Galápagos: The Islands That Changed the World describes how tragedy and murderous pirates curtailed settlement of the islands and how the islands’ pristine nature, spectacular geology, and defining isolation inspired Darwin’s ideas about evolution. The book explores the diverse land and marine habitats that shelter Galápagos species and considers the islands’ importance today as a frontier for science and a refuge for true wilderness. The book’s extensive gazetteer provides details about endemic plants and animals as well as travel advice about visitors’ sites, diving, photography, when to go, and what to take. Vividly illustrated throughout, this guide is an indispensable reference for natural history enthusiasts, armchair travelers, and island visitors alike.

    Colin Tudge argues that we are entering a new phase of biology in which, for the first time, biologists are achieving profound insight into life's true diversity and developing the tools to keep track of it. The Variety of Life heralds this new phase. The first part of the book describes why biologists now feel that there could have been as many as 4,000 billion species on Earth since life began. It then discusses the need for classification, beginning with the most basic principles--the strictly practical classification of fishmongers and foresters, who speak of "shellfish" and differentiate "hardwood" from "softwood"--and moves on to explore the intriguing deliberations of the modern "transformed cladists" and the novel contributions of molecular genetics. Part II describes the creatures themselves. It is divided into 24 sections, each describing a different group, illustrated by nearly 50 double-page spreads which present genealogical "trees" that summarize the evolutionary relationships between the creatures in each group. Some sections describe large, comprehensive groups such as the kingdoms of the Animals or the Plants. Others treat similar sub-groups in more detail, such as the Mammals, a class, or the Hominids, a family. In lively and accessible prose, all the significant groups of creatures--both alive and extinct--are described and their relationships clarified. For general readers and serious biologists alike, The Variety of Life offers an unprecedented storehouse of knowledge of life on earth.

    Learn: How to recognize tree shapes, flowers, buds, leaves, and fruits. Where each species grows. The parts of a tree, and the various kinds of trees.

    They inspire dreams. They represent freedom: from adults or adulthood, from duties and responsibilities, from an earthbound perspective. If we can't fly with the birds, at least we can nest with them. With lively writing and beautiful photographs, Treehouses paints a fascinating portrait of this ingenious branch of architecture. It provides a brief history of treehouses, from Caligula through the Medici to Queen Victoria. It shows how to design and build a treehouse, from picking the right tree to shingling the roof. And it tells the stories of dozens of treehouses and the people who built them, from simple platforms nailed together by kids to arboreal palaces constructed and lived in by grown-ups. The centerpiece of the book is a photo essay showing Pete Nelson building a spectacular octagonal treehouse thirty feet up an old-growth fir on Saltspring Island in British Columbia. With two hundred square feet of floor space, cedar paneling, and leaded French doors, the Saltspring treehouse is one of the finest specimens of the treehouse builder's art. Anyone who has ever built a treehouse, or dreamed of it, or read Swiss Family Robinson, will find Treehouses irresistible.

    Unlike the rest of the world's archipelagoes, it still has 95 percent of its prehuman quota of species. Wildlife of the Galapagos is the most superbly illustrated and comprehensive identification guide ever to the natural splendor of these incomparable islands--islands today threatened by alien species and diseases that have diminished but not destroyed what so enchanted Darwin on his arrival there in 1835. Covering over 200 commonly seen birds, mammals, reptiles, invertebrates, and plants, it reveals the archipelago's striking beauty through more than 400 color photographs, maps, and drawings and well-written, informative text. While the Galapagos Giant Tortoise, the Galapagos Sea Lion, and the Flightless Cormorant are recognized the world over, these thirty-three islands--in the Pacific over 600 miles from mainland Ecuador--are home to many more unique but less famous species. Here, reptiles well outnumber mammals, for they were much better at drifting far from a continent the archipelago was never connected with; the largest native land mammals are rice rats. The islands' sixty resident bird species include the only penguin to breed entirely in the tropics and to inhabit the Northern Hemisphere. There is a section offering tips on photography in the Equatorial sunlight, and maps of visitors' sites as well as information on the archipelago's history, climate, geology, and conservation. Wildlife of the Galapagos is the perfect companion for anyone who wants to know what so delighted Darwin. Covers over 200 commonly seen species including birds, mammals, reptiles, invertebrates, plants, and coastal and marine life Illustrated with over 400 color photographs, maps, and drawings; includes maps of visitors' sites Written by wildlife experts with extensive knowledge of the area Includes information on the history, climate, geology, and conservation of the islands The most complete identification guide to the wildlife of the Galapagos

    As a hardy, easy care, and potentially long-lived lizard, the leopard gecko is the perfect size, attractive in its velvety skin, and fairly easy to breed. The subject of breeding geckos is covered in multiple chapters in this book led by author and herp expert de Vosjoli, who is joined by gecko specialists Dr. Roger Klingenberg, Ron Tremper, and Dr. Brian Viets, who each contribute special chapters to this up-to-date and authoritative guide. Colorfully illustrated, Leopard Geckos provides excellent general guidelines for keepers who wish to add a gecko to their vivarium and maintain their pet in excellent health and condition. The authors provide an introduction to gecko characteristics including distribution, size, longevity, and growth rate, to help beginners better understand the anatomy and behavior of these fascinating lizards. This Advanced Vivarium Systems title includes information about selecting a healthy leopard gecko, handling, housing needs, water and feeding requirements, and shedding and tail loss. Dr. Klingenberg provides the chapter “The Recognition and Treatment of Disease,” which covers specific disorders keepers should be aware of. De Vosjoli begins the discussion on breeding leopard geckos, and then is joined by Dr. Viets for a chapter on “Incubation Temperature and Hatchling Sex and Pigmentation.” Tremper’s chapter on “Color and Pattern Variations” focuses on the genetic aspects of breeding leopard geckos. The book also discusses the African fat-tailed gecko plus other eublepharids, including the African clawed gecko, Japanese leopard gecko, Malaysian cat gecko, and the Central American banded gecko.

    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.

    Naturalists Kenn Kaufman and Eric R. Eaton use a broad ecological approach rather than overly technical terms, making the book accessible and easy to use. Their lively and engaging text emphasizes the insects that are most likely to draw attention and also includes helpful details on a wide array of lesser-known but recognizable groups. The guide is lavishly illustrated, with more than 2,350 digitally enhanced photographs representing every major group of insects found in North America north of Mexico.
