Reproductive Biology Of The Great Apes

Reproductive Biology of the Great Apes: Comparative and Biomedical Perspectives discusses the great ape reproduction. The book opens with the menstrual cycle of apes as a good foundation for the subject areas that follow. Accordingly, Chapter 2 focuses on the endocrine changes during the stage of pregnancy among apes, specifically the hormonal changes in chimpanzee. Chapter 3 deals mainly on the condition postpartum amenorrhea. In Chapter 4, the reproductive and endocrine development – from fetal development, infancy, juvenile, to puberty – is discussed. Chapters 5 and 6 thoroughly discuss the female and male ape’s genital tract and their secretions. The sole topic of Chapter 7 deals mainly with the comparative aspects of ape steroid hormone metabolism. Meanwhile, Chapter 8 tackles laboratory research on apes’ sexual behavior. The succeeding chapters talk about the chimpanzee, gorilla, and orangutan reproduction in the wild. Chapters 12 and 13 basically look upon the behaviors of the great apes, specifically intermale competition and sexual selection. The next chapters (14 and 15) look at the necessity of breeding and managing apes in captivity to ensure their continued survival. Lastly, Chapter 16 highlights the significance and great value of apes as models and comparative study in human reproduction. This book will be of great use to human physiologists, comparative anatomists and zoologists, primatologists, ape breeders, and biomedical scientists.

Primate Sexuality provides a synthesis of current research on the evolution and physiological control of sexual behaviour in the primates - prosimians, monkeys, apes, and human beings. This new edition has been updated and greatly expanded throughout to incorporate a decade of new research findings.

The International Life Sciences Institute (ILSI) was estab lished in 1978 to stimulate and support scientific research and educational programs related to nutrition, toxicology, and food safety, and to encourage cooperation in these programs among scientists in universities, industry, and government agencies to assist in the resolution of health and safety issues. To supplement and enhance these efforts, ILSI has made a major commitment to supporting programs to harmonize toxicologic testing, to advance a more uniform interpreta tion of bioassay results worldwide, to promote a common understanding of lesion classifications, and to encourage wide discussion of these topics among scientists. The Mo nographs on the Pathology of Laboratory Animals are de signed to facilitate communication among those involved in the safety testing of foods, drugs, and chemicals. The complete set will cover all organ systems and is intended for use by pathologists, toxicologists, and others con cerned with evaluating toxicity and carcinogenicity stu dies. The international nature of the project - as reflected in the composition of the editorial board and the diversity of the authors and editors -strengthens our expectations that understanding and cooperation will be improved worldwide through the series. Alex Malaspina President International Life Sciences Institute Preface This book, on Nonhuman Primates, is the eleventh volume of a set pre pared under the sponsorship of the International Life Sciences Institute (ILSI).

The great apes (chimpanzees, bonobos, gorillas and orangutans) are our closest living relatives, sharing a common ancestor only five million years ago. We also share key features such as high intelligence, omnivorous diets, prolonged child-rearing and rich social lives. The great apes show a surprising diversity of adaptations, particularly in social life, ranging from the solitary life of orangutans, through patriarchy in gorillas to complex but different social organisations in bonobos and chimpanzees. As great apes are so close to humans, comparisons yield essential knowledge for modelling human evolutionary origins. Great Ape Societies provides comprehensive up-to-date syntheses of work on all four species, drawing on decades of international field work, zoo and laboratory studies. It will be essential reading for students and researchers in primatology, anthropology, psychology and human evolution.

Collective works on the orang-utan, from the broader evolutionary perspective to the details of what makes this animal not just unique among humanoids, but distinctive among primates in general.

Sperm Competition and the Evolution of Animal Mating Systems describes the role of sperm competition in selection on a range of attributes from gamete morphology to species mating systems. This book is organized into 19 chapters and begins with the conceptualization of sperm competition as a subset of sexual selection and its implications for the insects. The following chapter describes the relationship between multiple mating and female fitness, with an emphasis on determining the conditions under which selection on females is likely to counteract selection on males for avoiding sperm competition. Other chapters consider the female perspective on sperm competition; the evolutionary causation at the level of the individual male gamete; and the correlation of high paternal investment and sperm precedence in the insects. The remaining chapters are arranged phylogenetically and explore the sperm competition in diverse animal taxa, such as the Drosophila, Lepidoptera, spiders, amphibians, and reptiles. These chapters also cover the evolution of direct versus indirect sperm transfer among the arachnids or the problem for kinship theory presented by multiple mating and sperm competition in the Hymenoptera. This book further discusses the remarkable potential for sperm competition among certain temperate bat species whose females store sperm through winter hibernation and the mixed strategies and male-caused female genital trauma as possible sperm competition adaptations in poeciliid fishes. The concluding chapter examines the predictions concerning testes size and mating systems in the primates and the possible role of sperm competition in human selection. This book is of great value to reproductive biologists and researchers.
