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.

    It is the history of who you are and how you came to be. It is unique to you, as it is to each of the 100 billion modern humans who have ever drawn breath. But it is also our collective story, because in every one of our genomes we each carry the history of our species births, deaths, disease, war, famine, migration, and a lot of sex. Since scientists first read the human genome in 2001, it has been subject to all sorts of claims, counterclaims, and myths. In fact, as Adam Rutherford explains, our genomes should be read not as instruction manuals, but as epic poems. DNA determines far less than we have been led to believe about us as individuals, but vastly more about us as a species. In this captivating journey through the expanding landscape of genetics, Adam Rutherford reveals what our genes now tell us about history, and what history tells us about our genes. From Neanderthals to murder, from redheads to race, dead kings to plague, evolution to epigenetics, this is a demystifying and illuminating new portrait of who we are and how we came to be."

    They are also astonishingly diverse in their shapes, patterns, textures, and colors—in nature’s fashion show, they are the haute couture of marine life.This collection of more than 250 remarkable images is the result of seven years of painstaking fieldwork across the Pacific Ocean, using photographic techniques that Middleton developed to capture these extremely fragile creatures on camera. She also provides short essays that examine the place these invertebrates occupy on the tree of life, their vast array of forms, and their lives in the ocean. Scientist Bernadette Holthuis contributes profiles describing each species, many of them for the first time. Middleton’s book is a stunning new view of nature that harmoniously combines art and science.

    Today there are three cats for every dog on the planet, and yet cats remain more mysterious, even to their most adoring owners. Unlike dogs, cats evolved as solitary hunters, and, while many have learned to live alongside humans and even feel affection for us, they still don’t quite get us” the way dogs do, and perhaps they never will. But cats have rich emotional lives that we need to respect and understand if they are to thrive in our company.In Cat Sense, renowned anthrozoologist John Bradshaw takes us further into the mind of the domestic cat than ever before, using cutting-edge scientific research to dispel the myths and explain the true nature of our feline friends. Tracing the cat’s evolution from lone predator to domesticated companion, Bradshaw shows that although cats and humans have been living together for at least eight thousand years, cats remain independent, predatory, and wary of contact with their own kind, qualities that often clash with our modern lifestyles. Cats still have three out of four paws firmly planted in the wild, and within only a few generations can easily revert back to the independent way of life that was the exclusive preserve of their predecessors some 10,000 years ago. Cats are astonishingly flexible, and given the right environment they can adapt to a life of domesticity with their owners—but to continue do so, they will increasingly need our help. If we’re to live in harmony with our cats, Bradshaw explains, we first need to understand their inherited quirks: understanding their body language, keeping their environments—however small—sufficiently interesting, and becoming more proactive in managing both their natural hunting instincts and their relationships with other cats.A must-read for any cat lover, Cat Sense offers humane, penetrating insights about the domestic cat that challenge our most basic assumptions and promise to dramatically improve our pets’ lives—and ours.

    It has the most balanced approach to environmental science instruction, with bias-free comparative diagrams throughout and a focus on prevention of and solutions to environmental problems. Tyler Miller is the most successful author in academic writing on environmental science because of his attention to currency, trend setting presentation of content, ability to predict student and instructor needs for new and different supplements, and his ability to retain the hallmarks on which instructors have come to depend. The content in the 14th edition of LIVING IN THE ENVIRONMENT is everything you have come to expect and more. In this edition, the author has added the "How Would You Vote?" feature, which is an application of environmental science-related topics in the news. Students apply their environmental science knowledge from the book to a Web activity, which helps them investigate environmental science issues in a structured manner. They then cast their votes on the Web. Results are then tallied. Also found at the Miller website is the much used "Updates on Line." Updated twice a year with articles from InfoTrac College Edition service, CNN® Today Video Clips, and Web links, instructors can seamlessly incorporate the most current news articles and research findings to support text presentations. This is a time saver for instructors and part-time teachers who can quickly determine what ancillary materials they want to utilize in just minutes. As with the last edition, this text is packaged with a free Student CD-ROM entitled "Interactive Concepts in Environmental Science." Organized by chapter, the CD gives students links to relevant resources, narrated animations, interactive figures, and prompts to review material and test themselves.

    Assuming no prior science knowledge, this book supports main concepts with clinical applications, making them more relevant to students pursuing careers in the allied health field.
