Study of extinction of species on islands and the impli-cations for other ecologic systems.

Why have island ecosystems always suffered such high rates of extinction? In our age, with all the world's landscapes, from Tasmania to the Amazon to Yellowstone, now being carved into island-like fragments by human activity, the implications of this question are more urgent than ever. Over the past eight years, David Quammen has followed the threads of island biogeography on a globe-encircling journey of discovery.

"David Quammen is simply the best natural essayist working today."--Tim Cahill, author of Lost in My Own Backyard "Lively writing about science and nature depends less on the offering of good answers, I think, than on the offering of good questions," said David Quammen in the original introduction to Natural Acts. For more than two decades, he has stuck to that credo. In this updated version of curiosity leads him from New Mexico to Romania, from the Congo to the Amazon, asking questions about mosquitoes (what are their redeeming merits?), dinosaurs (how did they change the life of a dyslexic Vietnam vet?), and cloning (can it save endangered species?). This revised and expanded edition best-loved "Natural Acts" columns, which first appeared in Outside magazine in the early 1980s, and includes recent pieces such as "Planet of Weeds," an influential new Natural Acts is an eye-opening journey that will please both Quammen fans and newcomers to his work.

A masterpiece of science reporting that tracks the animal origins of emerginghuman diseases.

"Rich detail and vivid anecdotes of adventure....A treasure trove of exotic fact and hard thinking." —New York Times Book Review For millennia, lions, tigers, and their man-eating kin have kept our dark, scary forests dark and scary, and their predatory majesty has been the stuff of folklore. But by the year 2150 big predators may only exist on the other side of glass barriers and chain-link fences. Their gradual disappearance is changing the very nature of our existence. We no longer occupy an intermediate position on the food chain; instead we survey it invulnerably from above—so far above that we are in danger of forgetting that we even belong to an ecosystem. Casting his expert eye over the rapidly diminishing areas of wilderness where predators still reign, the award-winning author of The Song of the Dodo and The Tangled Tree examines the fate of lions in India's Gir forest, of saltwater crocodiles in northern Australia, of brown bears in the mountains of Romania, and of Siberian tigers in the Russian Far East. In the poignant and troublesome ferocity of these embattled creatures, we recognize something primeval deep within us, something in danger of vanishing forever.

Nine months after the explosion, a French expedition searching for signs of life discovered a single spider that had crossed to the island on a balloon of silk. Life had returned to Krakatau. Scientists have been studying the island ever since.

Like its predecessor, Biogeography, Second Edition, aims to integrate the specialized subdisciplines that threaten to divide the field. It combines ecological and historical perspectives to show how contemporary environments, earth history, and evolutionary processes have shaped the distributions of species and the patterns of biodiversity. It illustrates general patterns and processes using examples from different groups of plants and animals from diverse habitats and geographic regions. Biogeography, Second Edition, consists of 19 chapters, organized into five sections. The book is beautifully illustrated with hundreds of figures and maps, and contains a glossary and extensive bibliography. Starting from simple facts and principles, and assuming only a rudimentary knowledge of biology, geography, and earth history, the book seeks to explain the relationships between the patterns of plant and animal distributions and the mechanistic processes that have produced them. Throughout, the emphasis is on the interplay between unifying concepts and the evidence that supports or challenges these ideas.
