The 1890s was an exciting time in American biology, a time of great intellectual debate and turmoil. Much of this activity centered on the now-famous Evening Lectures delivered at the Woods Hole Marine Biological Laboratory on Cape Cod, where leading biologists gathered to research the leading issues of the day. There was no better way to learn about what was being discussed and debated at the cutting edge of biology than through the Evening Lectures. The lectures of outstanding scientists such as C. 0. Whitman, E. B. Wilson, E. G. Conklin, J. Loeb, and T. H. Morgan redefined our thinking about biology.

These Evening Lectures stimulated major biological revolutions: the conversion of embryology to an independent discipline; the beginnings of ethology; the rise of genetics and especially cytogenetics; and the application of chemistry and physics to cell function-the birth of what is now called cell biology. Some of the central problems that scientists still puzzle over were first proposed at Woods Hole.

Not only are these lectures important scientific accomplishments, they also provide an invaluable record of the beginnings of a truly American school of biology. Printed in a limited edition, they have remained inaccessible to many people interested in knowing more about the meteoric rise of American biology. Jane Maienschein has selected key lectures, written an introductory essay, and provided brief explanations of the significance and impact of each lecture. Ernst Mayr, distinguished biologist and historian, has added a Foreword about the intellectual importance of the lectures to the formation of American biology; and Paul Gross, present Director of the Marine Biological Laboratory, has contributed an Epilogue that conveys the excitement and later significance of the 1890s.

For most of us the word "desert" conjures up images of barren wasteland, vast, dry stretches inimical to life. But for a great array of creatures, perhaps even more plentiful than those who inhabit tropical rainforests, the desert is a haven and a home. Travel with Michael Mares into the deserts of Argentina, Iran, Egypt, and the American Southwest and you will encounter a rich and memorable variety of these small, tenacious animals, many of them first discovered by Mares in areas never before studied. Accompanying Mares on his forays into these hostile habitats, we observe the remarkable behavioral, physiological, and ecological adaptations that have allowed such little-known species of rodents, bats, and other small mammals to persist in an arid world. At the same time, we see firsthand the perils and pitfalls that await biologists who venture into the field to investigate new habitats, discover new species, and add to our knowledge of the diversity of life.

Filled with the seductions and trials that such adventures entail, A Desert Calling affords an intimate understanding of the biologist's vocation. As he astonishes us with the range and variety of knowledge to be acquired through the determined investigation of little-known habitats, Mares opens a window on his own uncommon life, as well as on the uncommon life of the remote and mysterious corners of our planet.

What do such words as “information,” “displacement,” and “courtship” mean to the growing ranks of ethologists who study animal behavior? Like all sciences, ethology has accumulated its own set of concepts and terms, taken from everyday language, borrowed from neighboring disciplines, or coined especially to describe novel ideas and phenomena. Klaus Immelmann and Colin Beer have responded to the acute need for an authoritative dictionary of ethology with this valuable guide to the world of animal behavior.

The authors present a balance of historical, enduring, and current terminology, providing clear and concise definitions of the terms central to ethological writing. They give special treatment to terms from related disciplines, particularly evolutionary biology, physiology, ecology, and sociobiology, and to controversial concepts such as “instinct,” “motivation,” and “imprinting.” For words like these, the authors take pains to explain the nature of the problem, to distinguish differences of meaning, and to chart the range of application. A preponderance of terms relate to the behavior of higher vertebrates, especially mammals and birds, since these animals supply a high proportion of ethology’s basic ideas and technical concepts.

Representing the culmination of two decades of assiduous scholarship, this book will be immensely useful to neophyte and professional alike.

"In the Amazon Basin the greatest violence sometimes begins as a flicker of light beyond the horizon. There in the perfect bowl of the night sky, untouched by light from any human source, a thunderstorm sends its premonitory signal and begins a slow journey to the observer, who thinks: the world is about to change." Watching from the edge of the Brazilian rain forest, witness to the sort of violence nature visits upon its creatures, Edward O. Wilson reflects on the crucible of evolution, and so begins his remarkable account of how the living world became diverse and how humans are destroying that diversity.

Wilson, internationally regarded as the dean of biodiversity studies, conducts us on a tour through time, traces the processes that create new species in bursts of adaptive radiation, and points out the cataclysmic events that have disrupted evolution and diminished global diversity over the past 600 million years. The five enormous natural blows to the planet (such as meteorite strikes and climatic changes) required 10 to 100 million years of evolutionary repair. The sixth great spasm of extinction on earth--caused this time entirely by humans--may be the one that breaks the crucible of life. Wilson identifies this crisis in countless ecosystems around the globe: coral reefs, grasslands, rain forests, and other natural habitats. Drawing on a variety of examples such as the decline of bird populations in the United States, the extinction of many species of freshwater fish in Africa and Asia, and the rapid disappearance of flora and fauna as the rain forests are cut down, he poignantly describes the death throes of the living world's diversity--projected to decline as much as 20 percent by the year 2020.

All evidence marshaled here resonates through Wilson's tightly reasoned call for a spirit of stewardship over the world's biological wealth. He makes a plea for specific actions that will enhance rather than diminish not just diversity but the quality of life on earth. Cutting through the tangle of environmental issues that often obscure the real concern, Wilson maintains that the era of confrontation between forces for the preservation of nature and those for economic development is over; he convincingly drives home the point that both aims can, and must, be integrated. Unparalleled in its range and depth, Wilson's masterwork is essential reading for those who care about preserving the world biological variety and ensuring our planet's health.
