Tortoises may be the first family of higher animals to become extinct in the coming decades. They are losing the survival race because of what distinguishes them, in particular their slow, steady pace of life and reproduction. The Last Tortoise offers an introduction to these remarkable animals and the extraordinary adaptations that have allowed them to successfully populate a diverse range of habitats—from deserts to islands to tropical forests. The shields that protect their shoulders and ribs have helped them evade predators. They are also safeguarded by their extreme longevity and long period of fertility. Craig Stanford details how human predation has overcome these evolutionary advantages, extinguishing several species and threatening the remaining forty-five. At the center of this beautifully written work is Stanford’s own research in the Mascarene and Galapagos Islands, where the plight of giant tortoise populations illustrates the threat faced by all tortoises. He addresses unique survival problems, from genetic issues to the costs and benefits of different reproductive strategies. Though the picture Stanford draws is bleak, he offers reason for hope in the face of seemingly inevitable tragedy. Like many intractable environmental problems, extinction is not manifest destiny. Focusing on tortoise nurseries and breeding facilities, the substitution of proxy species for extinct tortoises, and the introduction of species to new environments, Stanford’s work makes a persuasive case for the future of the tortoise in all its rich diversity.

Land tortoises of the genus Gopherus are an important element in the fauna of southern North America. Information on the four living species is widely scattered in various popular and scientific books and periodicals. An extensive search was made for literature on behavior and ecology of tortoises in this group. This compilation is intended as an aid to herpetologists and conservationists interested in these animals; it is hoped that it will serve as a directory to available information, prevent unnecessary duplication of effort, and help illuminate research needs. Each numbered item in the bibliography has been read and its contents indexed by subject. The references cited in each article have also been checked. A copy of each paper listed is on file in the Library of Archibold Biological Station.

A Sheltered Life offers a fascinating look at one of the world's strangest and most wondrous animals--whose significance in modern science and culture cannot be underestimated. In an engaging blend of cultural and natural history, the book ranges from the earliest mention of the tortoises many millennia ago, to the wholesale plunder of their populations starting in the sixteenth century, to modern attempts to protect the tortoise and track down members of what were once believed to be extinct populations.

Tortoise is the first cultural history of these long-lived and intriguing creatures, which have existed for more than 200 million years. The book covers tortoises worldwide, in evolution, myth and reality, ranging across paleontology, natural history, myth, folklore, art forms, literature, veterinary medicine and trade regulations. The tortoise has been seen as an Atlas-like creature supporting the world, as the origin of music and as a philosophical paradox. Peter Young examines the tortoise in all these guises, as well as a military tactical formation, its exploitation by mariners and others for food, as ornament (in tortoiseshell), as a motif in art, and in space research. He looks at the movement away from exploitation to conservation and even the uses of the tortoise in advertising. As well as examples of species, illustrations from around the world include monuments, sculptures, coins, stamps, objets d’art, drawings, cartoons, advertisements and X-rays. The book will appeal not only to tortoise lovers but also to readers of cultural histories around the world. "Peter Young’s Tortoise, on the other claw, can be warmly recommended."—Jonathan Bate, The Times
