This volume presents a broad spectrum of research on the Cayo Santiago macaques, a unique free-ranging colony of rhesus macaques in Puerto Rico. It includes thirteen scientific studies on the behavior and biology of the Cayo Santiago macaques, as well as a detailed history of the colony and a complete bibliography of over 260 scientific publications based on work at Cayo Santiago from 1938 through 1984. The chapters represent examples of both short- and long-term research conducted on the island over the past several years. Some are reviews, providing a synopsis of complex longitudinal studies of behavior, vocal communication, functional morphology, genetics, and population dynamics. Others document the results of opportunistic studies of behavior or biological surveys. The chapters cover a broad range of topics, but all share a common dependence on the detailed life history and genealogical data which make the Cayo Santiago macaque colony an important international research resource.
This is a study of the functional morphology and behavioral dynamics underlying locomotor ontogeny in a free-ranging group of rhesus monkeys (Macaca mulatta) at Cayo Santiago, Puerto Rico. It tests the hypothesis that developmental modifications of morphology in the shoulder gird le and forelimb of Macaca mulatta are associated with changes in the frequencies of locomotor and postural behavior, and it demonstrates systematic study of the morphological and behavioral development of primates can be used to assess the validity of predicting habitual locomotor pat terns from anatomical evidence.Eight osteometric features of the scapula, clavicle and humerus, which reflect myological ada ptations...
The concept of using encapsulation for the immunoprotection of transplanted cells was introduced for the first time in the 1960s. "[Microencapsulated cells] might be protected from destruction and from partici pation in immunological processes, while the enclosing membrane would be permeable to small molecules of specific cellular product which could then enter the general extracellular compartment of the recipient. For instance, encapsulated endocrine cells might survive and maintain an effective supply of hormone." (Chang, Ph. D. Thesis, McGill University, 1965; Chang et aI., Can J Physiol PharmacoI44:115-128, 1966). We asked Connaught Laboratories, Ltd., in Toronto to put this concept int...

The phenomenon of friendship is universal. Friends, after all, are the family we choose. But what makes these bonds not just pleasant but essential, and how do they affect our bodies and our minds? In Friendship, science journalist Lydia Denworth takes us in search of the biological, psychological, and evolutionary foundations of this important bond. She finds that the human capacity for friendship is as old as humanity itself, when tribes of people on the African savanna grew large enough for individuals to seek meaningful connection with those outside their immediate families. Lydia meets scientists at the frontiers of brain and genetics research, and discovers that friendship is reflected...
A human female is born, lives her life, and dies within the space of a few decades, but the shape of her life has been strongly influenced by 50 million years of primate evolution and more than 100 million years of mammalian evolution. How the individual female plays out the stages of her life--from infancy, through the reproductive period, to old age--and how these stages have been formed by a long evolutionary process, is the theme of this collection. Written by leading scholars in fields ranging from evolutionary biology to cultural anthropology, these essays together examine what it means to be female, integrating the life histories of marine mammals, monkeys, apes, and humans. The resul...
