This volume is the first scholarly book on the antelope that dominate the savanna ecosystems of eastern and southern Africa. It presents a synthesis of research conducted over a span of fifty years, mainly on the wildebeests in the Ngorongoro and Serengeti ecosystems, where eighty percent of the world's total wildebeest population lives. Wildebeest and other grazing mammals drive the ecology and evolution of the savanna ecosystem. Estes describes this process as well as detailing the wildebeest's life history, focusing on its social organization and unique reproductive system, which are adapted to the animal's epic annual migrations. He also examines conservation issues that affect wildebeest, including range-wide population declines.

Written for anyone interested in green development - including policy makers, architects, developers, builders, and homeowners - this practical guide focuses on the central question of how to conserve biodiversity in neighborhoods and to minimize development impacts on surrounding habitats. "The Green Leap" specifically helps move green development beyond the design stage by thoroughly addressing construction and post-construction issues. Incorporating many real-world examples, Mark Hostetler explains key conservation concepts and techniques, with specific advice for a wide variety of stakeholders that are interested in creating and maintaining green developments. He outlines the key players and principles needed to establish biodiverse communities and illustrates eight key design and management strategies. "The Green Leap" not only offers essential information for constructing new developments but also helps existing communities retrofit homes, yards, and neighborhoods to better serve both people and nature.

Although the American bison was saved from near-extinction in the nineteenth century, today almost all herds are managed like livestock. The Yellowstone area is the only place in the United States where wild bison have been present since before the first Euro-Americans arrived. But these bison pose risks to property and people when they roam outside the park, including the possibility that they can spread the abortion-inducing disease brucellosis to cattle. Yet measures to constrain the population threaten their status as wild animals.Mary Ann Franke's To Save the Wild Bison is the first book to examine the ecological and political aspects of the bison controversy and how it reflects changing attitudes toward wildlife. The debate has evoked strong emotions from all sides, including park officials, environmentalists, livestock growers, and American Indians. In describing political compromises among competing positions, Franke does not so much champion a cause as critique the process by which federal and state officials have made and carried out bison management policies. She shows that science, however valuable a tool, cannot by itself resolve what is ultimately a choice among conflicting values.
