Some bask unseen at the top of trees in London parks; others lurk at the bottom of damp bogs in Scotland. Several are virtually extinct. This book charts the author's quest to find all 59, from the Adonis Blue to the Dingy Skipper.

    Sometimes grizzlies kill people, and in exceptionally rare cases they even eat them. Those incidents are the focus of this book because that's what makes bears so interesting, such a huge part of our culture and our collective imagination.

    bataar bones he was impressed. The enormous skull and teeth betrayed the apex predators close relation to the storied Tyrannosaurus rex, the most famous animal that ever lived. Prokopi's obsession with fossils had begun decades earlier, when he was a Florida boy scouring for shark teeth and Ice Age remnants, and it had continued as he built a thriving business hunting, preparing, and selling specimens to avid collectors and private museums around the world. To scientists' fury and dismay, there was big money to be made in certain corners of the fossil trade. Prokopi didn't consider himself merely a businessman, though. He also thought of himself as a vital part of paleontology--as one of the lesser-known artistic links in bringing prehistoric creatures back to life--and saw nothing wrong with turning a profit in the process. Bone hunting was expensive, risky, controversial work, and he increasingly needed bigger "scores." By the time he acquired a largely complete skeleton of T. bataar and restored it in his workshop, he was highly leveraged and drawing quiet scorn from peers who worried that by bringing such a big, beautiful Mongolian dinosaur to market he would tarnish the entire trade. Presenting the skeleton for sale at a major auction house in New York City, he was relieved to see the bidding start at nearly $1 million---only to fall apart when the president of Mongolia unexpectedly stepped in to question the specimen's origins and demand its return. An international custody battle ensued, shining new light on the black market for dinosaur fossils, the angst of scientists who fear for their field, and the precarious political tensions in post-Communist Mongolia. The Prokopi case, unprecedented in American jurisprudence, continues to reverberate throughout the intersecting worlds of paleontology, museums, art, and geopolitics.

    Fish and Wildlife Service. In August 1992, she accepted an assignment that forever changed--and endangered--her life.

    The complex behavior of birds recounted here demonstrates that birds have sophisticated mental abilities previously unrecognized by conventional avian research. Ackerman supports her thesis with descriptions of the behavior of an entertaining variety of birds from across the world. She brings scientific research alive with personal field observations and accounts of her encounters with colorful and fascinating birds. Throughout, Ackerman reminds readers that birds are thinking beings--their brains are wired differently than those of mammals, giving them increased brain power despite their small size. She further makes the case that bird intelligence shows that humankind is not alone in using language and tools or constructing complex structures and manipulating other creatures.

    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.

    By some estimates, we may already have lost almost half of the songbirds that filled the skies only forty years ago. Renowned biologist Bridget Stutchbury convincingly argues that songbirds truly are the "canaries in the coal mine"--except the coal mine looks a lot like Earth and we are the hapless excavators.Following the birds on their six-thousand-mile migratory journey, Stutchbury leads us on an ecological field trip to explore firsthand the major threats to songbirds: pesticides, still a major concern decades after Rachel Carson first raised the alarm; the destruction of vital habitat, from the boreal forests of Canada to the diminishing continuous forests of the United States to the grasslands of Argentina; coffee plantations, which push birds out of their forest refuges so we can have our morning fix; the bright lights and structures in our cities, which prove a minefield for migrating birds; and global warming. We could well wake up in the near future and hear no songbirds singing. But we won't just be missing their cheery calls, we'll be missing a vital part of our ecosystem. Without songbirds, our forests would face uncontrolled insect infestations, and our trees, flowers, and gardens would lose a crucial element in their reproductive cycle. As Stutchbury shows, saving songbirds means protecting our ecosystem and ultimately ourselves.Some of the threats to songbirds: - The U.S. annually uses 4-5 million pounds of active ingredient acephate, an insecticide that, even in small quantities, throws off the navigation systems of White-throated sparrows and other songbirds, making them unable to tell north from south. - The U.S. Fish and Wildlife Service conservatively estimated that 4-5 million birds are killed by crashing into communication towers each year.- A Michigan study found that 600 domestic cats killed more than 6,000 birds during a typical 10-week breeding season.

    To Lee Goff and his fellow forensic entomologists, each body recovered at a crime scene is an ecosystem, a unique microenvironment colonized in succession by a diverse array of flies, beetles, mites, spiders, and other arthropods: some using the body to provision their young, some feeding directly on the tissues and by-products of decay, and still others preying on the scavengers.Using actual cases on which he has consulted, Goff shows how knowledge of these insects and their habits allows forensic entomologists to furnish investigators with crucial evidence about crimes. Even when a body has been reduced to a skeleton, insect evidence can often provide the only available estimate of the postmortem interval, or time elapsed since death, as well as clues to whether the body has been moved from the original crime scene, and whether drugs have contributed to the death.An experienced forensic investigator who regularly advises law enforcement agencies in the United States and abroad, Goff is uniquely qualified to tell the fascinating if unsettling story of the development and practice of forensic entomology.

    The author recounts his experiences observing sharks in the open seas, describes their characteristics, and discusses the safety precautions that should be taken around sharks.

    With their queens and celibate workers, these intriguing creatures have captured the imaginations of scientists and children alike for generations. Yet until now, no one had studied intensely the life cycle of the ant colony as a whole. An ant colony has a life cycle of about fifteen years—it is born, matures, and dies. But the individual ants that inhabit the colony live only one year. So how does this system of tunnels and caves in the dirt become so much more than the sum of its parts?Leading ant researcher Deborah Gordon takes the reader to the Arizona desert to explore this question. The answer involves the emerging insights of the new science of complexity, and contributes to understanding the evolution of life itself.

    I also hope that it will serve as a useful reference too for the many workers engaged in one type of solid state research activity or another, who may be without formal training in the subject.

    The book emphasizes a general introduction to probability theory and provides a detailed discussion of specific designs and analyses that are typically encountered in ecology and environmental science.
