A concise atlas of anatomy, it contains more than 200 specially prepared accurate and clear drawings that include material never illustrated before. The text is as informative as the drawings; written at a level appropriate to undergraduate students and to bird lovers in general, it discusses why birds look and act the way they do.Designed to supplement a basic ornithology textbook, the Manual of Ornithology covers systematics and evolution, topography, feathers and flight, the skeleton and musculature, and the digestive, circulatory, respiratory, excretory, reproductive, sensory, and nervous systems of birds, as well as field techniques for watching and studying birds. Each chapter concludes with a list of key references for the topic covered, with a comprehensive bibliography at the end of the volume. The book will be a guide and reference for every level of bird study—a basic tool for investigation for anyone curious about the fascinating world of birds.

    Yet this influence is not unidirectional, say the authors  of this fascinating book: people profoundly influence crow culture, ecology, and evolution as well. Examining the often surprising ways that crows and humans interact, John Marzluff and Tony Angell contend that those interactions reflect a process of “cultural coevolution.” They offer a challenging new view of the human-crow dynamic—a view that may change our thinking not only about crows but also about ourselves. Featuring more than 100 original drawings, the book takes a close look at the influences people have had on the lives of crows throughout history and at the significant ways crows have altered human lives. In the Company of Crows and Ravens illuminates the entwined histories of crows and people and concludes with an intriguing discussion of the crow-human relationship and how our attitudes toward crows may affect our cultural trajectory. As the authors state in their preface: “Crows and people share similar traits and social strategies. To a surprising extent, to know the crow is to know ourselves."

    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.

    Every person alive today is descended from him. How did this real-life Adam wind up as the father of us all? What happened to the descendants of other men who lived at the same time? And why, if modern humans share a single prehistoric ancestor, do we come in so many sizes, shapes, and races?Examining the hidden secrets of human evolution in our genetic code, Spencer Wells reveals how developments in the revolutionary science of population genetics have made it possible to create a family tree for the whole of humanity. Replete with marvelous anecdotes and remarkable information, from the truth about the real Adam and Eve to the way differing racial types emerged, The Journey of Man is an enthralling, epic tour through the history and development of early humankind.

    It is a hands-on guide to learning about the natural environment of California. Subjects covered include California natural history and geology, native plants and animals, California's freshwater resources and ecosystems, forest and rangeland resources, conservation biology, and the effects of global warming on California's natural communities. The Handbook also discusses how to create and use a field notebook, natural resource interpretation, citizen science, and collaborative conservation and serves as the primary text for the California Naturalist Program.

    This book is intended for use in a one- or two-semester course in environmental science, human ecology, or environmental studies at the college or advanced placement high school level.

    Two ganders who work together as a mated pair? Two female bears raising their four cubs together? A kangaroo with both a female pouch and male sex organs? Who's been keeping all this a secret? Homosexual mating and pairing occur in all species, so contends author Bruce Bagemihl in this well-researched book on animal homosexualities. Bagemihl is a biologist and researcher who went from teaching to working at Microsoft, and now he's produced one phenomenal book on gay, lesbian, bisexual, and tr ansgendered animal life. Bagemihl first shows how past biologists and anthropologists have made their errors in reportage regarding observations in the field of homosexual behavior among the beasts (interestingly enough, all homosexual behavior tended to be called either aggressive or passive, and not about mating or affection between animals, even though it was often the identical mating behavior as the heterosexually-oriented animals). In this often lively, but sometimes overwhelmingly encyclopedic study and listing of homosexual diversity in the animal kingdom, the author has done a phenomenal job of bringing science into a popular idiom so that the animal behavior he details i s understandable to the layperson.Biological Exuberance is divided into two main sections, "A Polysexual, Polygendered World" and "A Wondrous Bestiary: Portraits of Homosexual, Bisexual, and Transgendered Wildlife." The first section primarily deals with how we as a civilization have viewed animal sexuality in the past, and themyths we'vebuilt up around it, and the author's term, "biological exuberance." Here's how Bagemihl himself describes it. The essence ofBiological Exuberanceis that natural systems are driven as much by abundance and excess as they are by limitation and practicality. Seen in this light, homosexuality and nonreproductive heterosexuality are "expected" o ccurrences — they are one manifestation of an overall "extravagance" of biological systems that has many other expressions. In the second major section of the book, the author breaks his studies down into individual animal species and subgroupings of species. Fascinating, page-turning in its own way, and full of pictures of homosexual matings and sexual congress among our furry and feathered friends,Biolobical Exuberance is one of the most readable scientifically-based books of the year. Get this one. It is amazing.

    Journeying through human and natural history, The Whale is the result of his voyage of discovery into the heart of this obsession and the book that inspired it: Herman Melville's Moby-Dick. Taking us deep into their domain, Hoare shows us these mysterious creatures as they have never been seen before. Following in Ishmael's footsteps, he explores the troubled history of man and whale; visits the historic whaling locales of New Bedford, Nantucket, and the Azores; and traces the whale's cultural history from Jonah to Free Willy. Winner of the prestigious BBC Samuel Johnson Prize for Non-Fiction, The Whale is an unforgettable and often moving attempt to explain why these strange and beautiful animals still exert such a powerful hold on our imagination.

    Wild species, too, are escaping warming seas and desiccated lands, creeping, swimming, and flying in a mass exodus from their past habitats. News media presents this scrambling of the planet's migration patterns as unprecedented, provoking fears of the spread of disease and conflict and waves of anxiety across the Western world. On both sides of the Atlantic, experts issue alarmed predictions of millions of invading aliens, unstoppable as an advancing tsunami, and countries respond by electing anti-immigration leaders who slam closed borders that were historically porous.But the science and history of migration in animals, plants, and humans tell a different story. Far from being a disruptive behavior to be quelled at any cost, migration is an ancient and lifesaving response to environmental change, a biological imperative as necessary as breathing. Climate changes triggered the first human migrations out of Africa. Falling sea levels allowed our passage across the Bering Sea. Unhampered by barbed wire, migration allowed our ancestors to people the planet, catapulting us into the highest reaches of the Himalayan mountains and the most remote islands of the Pacific, creating and disseminating the biological, cultural, and social diversity that ecosystems and societies depend upon. In other words, migration is not the crisis--it is the solution.Conclusively tracking the history of misinformation from the 18th century through today's anti-immigration policies, The Next Great Migration makes the case for a future in which migration is not a source of fear, but of hope.

    The expedition was described by the two men in Sea of Cortez, published in 1941. The day-to-day story of the trip is told here in the Log, which combines science, philosophy and high-spirited adventure.Log from the Sea of Cortez includes the narrative of the journey and the essay “About Ed Ricketts.” It does not include pictures and detailed descriptions of the species collected by Steinbeck and Ricketts.
