Why do we behave the way we do? Biologist Paul Ehrlich suggests that although people share a common genetic code, these genes "do not shout commands at us...at the very most, they whisper suggestions." He argues that human nature is not so much result of genetic coding; rather, it is heavily influenced by cultural conditioning and environmental factors. With personal anecdotes, a well-written narrative, and clear examples, Human Natures is a major work of synthesis and scholarship as well as a valuable primer on genetics and evolution that makes complex scientific concepts...

Hanski, a leading thinker in metapopulation ecology, studies checkerspot butterfly populations in Finland. Ehrlich, one of the leading ecologists and conservation biologist, investigates checkerspot butterfly populations in California. This book reports on and synthsizes the major long-term research of both workers' careers on the population biology of checkerspot butterflies.

In this provocative book, the authors look at the interaction between population and food supply and offer a powerful and radical strategy for balancing human numbers with nutritional needs. Their proposals include improving the status of women, reducing racism and religious prejudice, reforming the agricultural system, and shrinking the growing gap between rich and poor.
"This ambitious, enlightened handbook is a cornucopia of strategies and ideas for concerned citizens and policymakers."--Publishers Weekly

From the cave walls at Lascaux to the last painting by Van Gogh, from the works of Shakespeare to those of Mark Twain, there is clear evidence that crows and ravens influence human culture. 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...

The Cold and the Dark is the record of the Conference on the Long-Term Worldwide Biological Consequences of Nuclear War, held in Washington, D.C., on October 31 to November 1, 1983. The conference involved over 200 scientists from many nations and drew together the best available scientific information. Its central finding was the phenomenon of nuclear winter: a much more profound and long-lasting devastation of the earth and atmosphere than had been believed possible before. In the two principal papers, Carl Sagan presents the atmospheric and climatic consequences of nuclear war and...

A pioneer in international conservation and wildlife ecology, Raymond Dasmann published his first book, the influential text Environmental Conservation, when the term "environment" was little known and "conservation" to most people simply meant keeping or storing. This delightful memoir tells the story of an unpretentious man who helped create and shape today's environmental movement. Ranging from Dasmann's travels to ecological hotspots around the world to his development of concepts such as bioregionalism and ecotourism, this autobiography is a story of international conservation...

This is the most complete and authoritative reference book about the birds of North America -- up to date and in field-guide format.
The Birder's Handbook is the first of its kind: a portable library of fascinating information not included in your identification guide. For each of the 646 species of birds that breed in North America, The Birder's Handbook will tell you at a glance:
* Where the bird nests, and which sex(es) build(s) the nest;
* How many eggs the bird lays, what they look like, which patent incubates and for how long, and how the young are cared...

As the human population skyrockets and the toxic impact of human society spreads, the natural habitats of birds degrade and diminish and the bird populations decline. Two hundred years ago, when the United States and Canada were home to less than 5 million people, they were also home to some 650 species of birds. Today, more than 280 million people live there, and 33 bird species have already been driven to extinction and well over 150 are in danger of extinction in all or parts of their range. This book, organized and written by the authors of The Birder's Handbook, and enriched by 191...

Though separated by thousands of miles, the United States and Australia have much in common. Geographically both countries are expansive-the United States is the fourth largest in land mass and Australia the sixth-and both possess a vast amount of natural biodiversity. At the same time, both nations are on a crash course toward environmental destruction. Highly developed super consumers with enormous energy footprints and high rates of greenhouse-gas emissions, they are two of the biggest drivers of climate change per capita. As renowned ecologists Corey J. A. Bradshaw and Paul R. Ehrlich...
