Book Description
Serengeti II: Dynamics, Management, and Conservation of an Ecosystem brings together twenty years of research by leading scientists to provide the most most thorough understanding to date of the spectacular Serengeti-Mara ecosystem in East Africa, home to one of the largest and most diverse populations of animals in the world. Building on the groundwork laid by the classic Serengeti: Dynamics of an Ecosystem, published in 1979 by the University of Chicago Press, this new book integrates studies of the ecosystem at every level—from the plants at the bottom of the visible food chain, to the many species of herbivores and predators, to the system as a whole. Drawing on new data from many long-term studies and from more recent research initiatives, and applying new theory and computer technology, the contributors examine the large-scale processes that have produced the Serengeti's extraordinary biological diversity, as well as the interactions among species and between plants and animals and their environment. They also introduce computer modeling as a tool for exploring these interactions, employing this new technology to test and anticipate the effects of social, political, and economic changes on the entire ecosystem and on particular species, and so to shape future conservation and management strategies.

Book Description
Animal migration is a magnificent sight: a mile-long blanket of cranes rising from a Nebraska river and filling the sky; hundreds of thousands of wildebeests marching across the Serengeti; a blaze of orange as millions of monarch butterflies spread their wings to take flight. Nature’s great migrations have captivated countless spectators, none more so than premier ecologist David S. Wilcove. In No Way Home, his awe is palpable—as are the growing threats to migratory animals. We may be witnessing a dying phenomenon among many species. Migration has always been arduous, but today’s travelers face unprecedented dangers. Skyscrapers and cell towers lure birds and bats to untimely deaths, fences and farms block herds of antelope, salmon are caught en route between ocean and river, breeding and wintering grounds are paved over or plowed, and global warming disrupts the synchronized schedules of predators and prey. The result is a dramatic decline in the number of migrants. Wilcove guides us on their treacherous journeys, describing the barriers to migration and exploring what compels animals to keep on trekking. He also brings to life the adventures of scientists who study migrants. Often as bold as their subjects, researchers speed wildly along deserted roads to track birds soaring overhead, explore glaciers in search of frozen locusts, and outfit dragonflies with transmitters weighing less than one one-hundredth of an ounce. Scientific discoveries and advanced technologies are helping us to understand migrations better, but alone, they won’t stop sea turtles and songbirds from going the way of the bison or passenger pigeon. What’s required is the commitment and cooperation of the far-flung countries migrants cross—long before extinction is a threat. As Wilcove writes, “protecting the abundance of migration is key to protecting the glory of migration.” No Way Home offers powerful inspiration to preserve those glorious journeys.

Book Description
Human exploitation of other mammals has passed through three histori cal phases, distinct in their ecological significance though overlapping in time. Initially, Homo sapiens was a predator, particularly of herbivores but also of fur-bearing predators. From about 11 000 years ago, goats and sheep were domesticated in the Middle East, rapidly replacing gazelles and other game as the principal source of meat. The principal crops, including wheat and barley, were taken into agriculture at about the same time, and the resulting Neolithic farming culture spread slowly from there over the subsequent 10 500 years. In a few places such as Mexico, Peru and China, this Middle Eastern culture met and merged with agricultural traditions that had made a similar but independent transition. These agricultural traditions provided the essential support for the industrial revolution, and for a third phase of industrial exploita tion of mammals. In this chapter, these themes are drawn out and their ecological signifi cance is investigated. Some of the impacts of humans on other mammals require consideration on a world-wide basis, but the chapter concen trates, parochially, on Great Britain. What have been the ecological consequences of our exploitation of other mammals? 2. 2 HISTORICAL PHASES OF EXPLOITATION 2. 2. 1 Predatory man Our nearest relatives - chimpanzees, orang utans and gorillas - are essentially forest species, deriving most of their diet from the fruits of forest trees and the shoots and leaves of plants.

Book Description
It was the age of exploration, the age of empire and conquest, and human beings were extending their reach—and their numbers—as never before. In the process, they were intervening in the world's natural environment in equally unprecedented and dramatic ways. A sweeping work of environmental history, The Unending Frontier offers a truly global perspective on the profound impact of humanity on the natural world in the early modern period. John F. Richards identifies four broadly shared historical processes that speeded environmental change from roughly 1500 to 1800 c.e.: intensified human land use along settlement frontiers; biological invasions; commercial hunting of wildlife; and problems of energy scarcity. The Unending Frontier considers each of these trends in a series of case studies, sometimes of a particular place, such as Tokugawa Japan and early modern England and China, sometimes of a particular activity, such as the fur trade in North America and Russia, cod fishing in the North Atlantic, and whaling in the Arctic. Throughout, Richards shows how humans—whether clearing forests or draining wetlands, transporting bacteria, insects, and livestock; hunting species to extinction, or reshaping landscapes—altered the material well-being of the natural world along with their own.

Book Description
Based on three years of study in the Serengeti National Park, George B. Schaller’s The Serengeti Lion describes the vast impact of the lion and other predators on the vast herds of wildebeest, zebra, and gazelle for which the area is famous. The most comprehensive book available on the lion, this classic work includes the author’s findings on all aspects of lion behavior, including its social system, population dynamics, hunting behavior, and predation patterns. “If you have only enough time to read one book about field biology, this is the one I recommend.”—Edward O. Wilson, Science “This book conveys not only the fascination of its particular study of lion behavior but the drama and wonder and beauty of the intimate interdependence of all living things.”—Saturday Review “This is an important book, not just for its valuable information on lions, but for its broad, open, and intelligent approach to problems that cut across the fields of behavior, populations, ecology, wildlife management, evolution, anthropology, and comparative biology.”—Richard G. Van Gelder, Bioscience
