Book Description
Primate Biogeography is a subject rarely addressed as a discipline in its own right. This comprehensive source introduces the reader to Primate Biogeography as a discipline. It highlights the many factors that may influence the distribution of primates, and reveals the wide range of approaches that are available to understanding the distribution of this order. The biogeography of primates in the past is a major component of our understanding of their evolutionary history and is an essential component of conservation biology. This book will appeal to primatologists, physical anthropologists, zoologists, and undergraduates in these areas.

Book Description
Socioecological models derive from the field of behavioral ecology, wherein social strategies are seen as adaptive responses to evolutionary and environmental forces. Chimpanzee social structure is largely explained by their dietary preference, however, little is known of chimpanzee adaptations to savanna-woodland environments. This dissertation tests the explanatory power of socioecological models on a chimpanzee population occupying the savanna-woodlands of Ugalla, Tanzania. By conducting a genetic survey across 624 km 2 , the following predictions are tested: (1) chimpanzees will occur at lower population densities than at forested sites, reflective of more diffusely distributed resources; (2) lower population densities, resulting in theoretically indefensible larger home ranges, will decrease benefits gained from male philopatry, resulting in a more continuous distribution of Y-chromosome haplotypes than is characteristic of populations studied in forested environments; and (3) genetic diversity will be lower, compared to other eastern chimpanzee populations, due to potential isolation. The population density of Ugalla is 0.25 (CI 0.16-0.38) individuals/km 2 , which is ten times less than the lowest forested site density. The Ugalla males appear to remain in their natal community, as geographic clusters of rare Y-chromosome haplotypes were found, suggesting the maintenance of male-philopatric communities. Relative genetic diversity of the Y-chromosome was exceptionally low among the males, and autosomal diversity was comparable to other eastern chimpanzee populations. These results indicate that although chimpanzees in Ugalla occur at much lower densities in response to a savanna-woodland habitat, male philopatry is maintained, suggesting this social structure is a highly conservative adaptation, and one which may have been shared with our earliest ancestors as they shifted to a similar environment.

Book Description
This book presents a series of review chapters on the various aspects of primate kinship and behavior, as a fundamental reference for students and professionals interested in primate behavior, ecology and evolution. The relatively new molecular data allow one to assess directly degrees of genetic relatedness and kinship relations between individuals, and a considerable body of data on intergroup variation, based on experimental studies in both free-ranging and captive groups has accumulated, allowing a rather full and satisfying reconsideration of this whole broad area of research. The book should be of considerable interest to students of social evolution and behavioral ecology.

Book Description
This book describes one of our closest relatives, the orangutan, and the only extant great ape in Asia. It is increasingly clear that orangutan populations show extensive variation in behavioural ecology, morphology, life history, and genes. Indeed, on the strength of the latest genetic and morphological evidence, it has been proposed that orangutans actually constitute two species which diverged more than a million years ago - one on the island of Sumatra the other on Borneo, with the latter comprising three subspecies. This book has two main aims. The first is to carefully compare data from every orangutan research site, examining the differences and similarities between orangutan species, subspecies and populations. The second is to develop a theoretical framework in which these differences and similarities can be explained. To achieve these goals the editors have assembled the world's leading orangutan experts to rigorously synthesize and compare the data, quantify the similarities or differences, and seek to explain them. Orangutans is the first synthesis of orangutan biology to adopt this novel, comparative approach. It analyses and compares the latest data, developing a theoretical framework to explain morphological, life history, and behavioural variation. Intriguingly, not all behavioural differences can be attributed to ecological variation between and within the two islands; relative rates of social learning also appear to have been influential. The book also emphasizes the crucial impact of human settlement on orangutans and looks ahead to the future prospects for the survival of critically endangered natural populations.

Book Description
The chimpanzees of Bossou in Guinea, West Africa, form a unique community which displays an exceptional array of tool use behaviors and behavioral adaptations to coexistence with humans. This community of Pan troglodytes verus has contributed more than three decades of data to the field of cultural primatology, especially chimpanzees’ flexible use of stones to crack open nuts and of perishable tools during foraging activities. The book highlights the special contribution of the long-term research at Bossou and more recent studies in surrounding areas, particularly in the Nimba Mountains and the forest of Diécké, to our understanding of wild chimpanzees’ tool use, cognitive development, lithic technology and culture. This compilation of research principally strives to uncover the complexity of the mind and behavioral flexibility of our closest living relatives. This work also reveals the necessity for ongoing efforts to conserve chimpanzees in the region. Chimpanzees have shed more light on our evolutionary origins than any other extant species in the world, yet their numbers in the wild are rapidly declining. In that sense, the Bossou chimpanzees and their neighbors clearly embody an invaluable cultural heritage for humanity as a whole. Readers can enjoy video clips illustrating unique behaviors of Bossou chimpanzees, in an exclusive DVD accompanying the hardcover or at a dedicated website described in the softcover.

Book Description
In this masterwork, Russell H. Tuttle synthesizes a vast research literature in primate evolution and behavior to explain how apes and humans evolved in relation to one another, and why humans became a bipedal, tool-making, culture-inventing species distinct from other hominoids. Along the way, he refutes the influential theory that men are essentially killer apes—sophisticated but instinctively aggressive and destructive beings. Situating humans in a broad context, Tuttle musters convincing evidence from morphology and recent fossil discoveries to reveal what early primates ate, where they slept, how they learned to walk upright, how brain and hand anatomy evolved simultaneously, and what else happened evolutionarily to cause humans to diverge from their closest relatives. Despite our genomic similarities with bonobos, chimpanzees, and gorillas, humans are unique among primates in occupying a symbolic niche of values and beliefs based on symbolically mediated cognitive processes. Although apes exhibit behaviors that strongly suggest they can think, salient elements of human culture—speech, mating proscriptions, kinship structures, and moral codes—are symbolic systems that are not manifest in ape niches. This encyclopedic volume is both a milestone in primatological research and a critique of what is known and yet to be discovered about human and ape potential.
