The orangutan is the most highly endangered species of great ape. Orangutans are threatened by deforestation, poaching, the illegal pet trade, and the isolation and fragmen tation of dwindling wild populations. Their conservation is impeded by certain aspects of their ecology (e. g. , a rain forest habitat) and certain features of their life history (e. g. , an eight-to twelve-year interbirth interval). Added to the U. S. Endangered Species List in 1970, the orangutan is now clearly on the road to extinction. The number of wild orangutans in Borneo and Sumatra is currently estimated to have decreased to between 12,300 and 20,571 individuals. Only 2% of original orangutan habitat is protected and some of these areas are now being destroyed. Clearly, attention to ecology, demography, censusing, rehabilitation, and conservation is essential if the orangutan is to survive in the wild beyond the next century. The protection of orangutans is a complex, multifaceted problem, involving such pressing issues as human poverty, overpopulation, and the economic development of Southeast Asia. Although the orangutan has been placed in Appendix I of the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES), more orangutans were sold illegally in Taiwan between 1990 and 1993 than are housed in all the world's zoos. In the past, scientific and public attention has centered on the African apes. For this reason, the sole Asian great ape, the orangutan, has been called the "neglected ape.

A REDISCOVERED WORK BY ONE OF THE MOST EXCITING NOVELISTS OF THE 1930S 'One of the most important novelists of our day' TIMES LITERARY SUPPLEMENT (1938) Virginia Hutton embarks upon an experiment. She will take an ape and raise it as a human child. She purchases an infant orangutan and names him Appius. She clothes him, feeds him, and puts him to bed in a cot every night. As Appius grows older, she teaches him to dress himself, to speak, to read, to stand and walk up straight, to eat his meals at the dining table with a knife and fork. She teaches him how to be human. The young orangutan is not always a willing student. His relationship with Virginia becomes fraught and flits between that of mother and child, teacher and student, scientist and experiment. But as Appius gains knowledge he moves ever closer to the one discovery Virginia does not want him to make: that of his true origins. Appius and Virginia explores the ongoing conflict between nature and nurture. It is also a chilling and unforgettable portrait of loneliness. G.E. Trevelyan wrote eight groundbreaking novels between 1932 and 1941 but her writing career was tragically cut short when her flat was hit by a German bomb during the Blitz. She died shortly afterwards and her books have subsequently been largely forgotten. This publication, the first reissue of any of her books since her death, seeks to restore the author to her rightful place in British literature.

Sexual Selection in Primates provides an account of all aspects of sexual selection in primates, combining theoretical insights, comprehensive reviews of the primate literature and comparative perspectives from relevant work on other mammals, birds and humans. Topics include sex roles, sexual dimorphism in weapons, ornaments and armaments, sex ratios, sex differences in behaviour and development, mate choice, sexual conflict, sex-specific life history strategies, sperm competition and infanticide. The outcome of the evolutionary struggle between the sexes, the flexibility of roles and the leverage of females are discussed and emphasised throughout. Sexual Selection in Primates is aimed at graduates and researchers in primatology, animal behaviour, evolutionary biology and comparative psychology.

Why do humans differ from other primates? What do those differences tell us about human evolution? Elaine Morgan gives a revolutionary hypothesis that explains our anatomic anomalies: why we walk on two legs, why we are covered in fat, why we can control our rate of breathing? The answers point to one conclusion: millions of years ago our ancestors were trapped in a semi-aquatic environment. In presenting her case Elaine Morgan forces scientists to question accepted theories of human evolution.

Gregory F. Tague’s An Ape Ethic and the Question of Personhood argues that great apes are moral individuals because they engage in a land ethic as ecosystem engineers to generate ecologically sustainable biomes for themselves and other species. Tague shows that we need to recognize apes as eco-engineers in order to save them and their habitats, and that in so doing, we will ultimately save earth’s biosphere. The book draws on extensive empirical research from the ecology and behavior of great apes and synthesizes past and current understanding of the similarities in cognition, social behavior, and culture found in apes. Importantly, this book proposes that differences between humans and apes provide the foundation for the call to recognize forest personhood in the great apes. While all ape species are alike in terms of cognition, intelligence, and behaviors, there is a vital contrast: unlike humans, great apes are efficient ecological engineers. Therefore, simian forest sovereignty is critical to conservation efforts in controlling global warming, and apes should be granted dominion over their tropical forests. Weaving together philosophy, biology, socioecology, and elements from eco-psychology, this book provides a glimmer of hope for future acknowledgment of the inherent ethic that ape species embody in their eco-centered existence on this planet.
