The amazing true stories of the greatest wildlife champions of our time.Wildlife conservation is at a critical juncture. While large, charismatic mammals may be the first animals that come to mind—the mere 3,000 wild tigers still in existence, the giraffes declared endangered for the first time just last year—it is not only these magnificent keystone species disappearing. A full third of all studied birds, reptiles, and mammals have suffered devastating population losses, and a third of all insects are now endangered, including crucial pollinators that sustain worldwide food supply. Over 15,000 animal species are now considered to be threatened with extinction. There are, however, bright spots that provide optimism—many of them due to the efforts of a small group of scientists and activists. In Saving Endangered Species, Robert W. Shumaker brings together ten conservation heroes, seven of them winners of the Indianapolis Prize, three of them recipients of the Jane Alexander Global Wildlife Ambassador Award. With moving immediacy, each wildlife defender offers their unique perspective on the state of wildlife conservation and the future of the natural world. Bringing to life their work in the field, each contributor also explains key concepts in wildlife conservation, reveals why they are important, and discusses what kinds of work can be done to address biodiversity loss.Contributors sharing their stories in their own words include• George Schaller, one of the founding fathers of wildlife conservation, who conducted the field work that resulted in the establishment of the world's largest wildlife preserve, the Arctic National Wildlife Refuge• Iain Douglas-Hamilton, who is widely credited with developing the metrics and methods that stemmed the tide of elephant poaching for ivory in Africa• Steven Amstrup, who discovered the disturbing truth that the sea ice polar bears rely on for traveling, hunting, and raising their young was disappearing • Russell Mittermeier, who has discovered over 20 new animal species, conducted field work in more than 30 countries around the globe, and authored 15 books on biodiversity• Harrison Ford, Academy Award–winning actor, who has been a passionate wildlife advocate and board member of Conservation International for over 25 years• Sigourney Weaver, three-time Academy Award nominee, whose work with the Dian Fossey Gorilla Fund has helped save thousands of gorillas in Rwanda and CongoThis unique book aims to win new recruits, inspire biologists and conservationists already in the field, and illustrate the profession's fundamental scientific tenets through wildlife champions' own exciting narratives. Covering issues from reproduction and prey-predator relationships to population dynamics and community engagement, Saving Endangered Species also addresses such thorny topics as overhunting, retaliatory killing by farmers, development-driven habitat loss, and the illegal wildlife trade. By encompassing a broad spectrum of subjects, this volume ultimately gives readers a first-person look into what it takes to dedicate oneself to the crucial field of wildlife conservation.Contributors: Jane Alexander, Steven C.

This revised and updated edition of the landmark publication reveals the current state of knowledge regarding animal tool behavior.When originally published in 1980, Animal Tool Behavior was the first volume to catalog and analyze the complete literature on tool use and manufacture in non-human animals. Benjamin B. Beck showed how animals—from insects to primates—employed different types of tools to solve numerous problems. This work inspired and energized legions of researchers to study the use of tools by a wide variety of species.This new edition reveals the current state of knowledge regarding animal tool behavior, updated and revised with 300 additional references that have been published since the second edition. Through a comprehensive synthesis of studies produced through 2023, Robert W. Shumaker, Kristina R. Walkup, and Benjamin B. Beck define tool use, discuss the modes of tool use that have emerged in the scientific literature, examine all forms of tool manufacture, and address common myths about non-human tool use. Specific examples involving invertebrates, birds, fish, and mammals describe the differing levels of sophistication of tool use exhibited by animals. This volume provides a thorough framework for understanding animal tool use and manufacture.
