First published in 1994. Infanticide is an extremely complex behavioral pattern that occurs throughout the animal kingdom and it must be considered not only in isolation but also from the viewpoint of an animal's care of its young. Infanticide and Parental Care will be of interest to zoologists, evolutionary biologists and biological anthropologists. The concept of infanticide is considered in different mammals such as humans, primates, pinnipeds, lions, dwarf mongooses and prairie dogs and in non-mammals including insects and birds. Infanticide and Parental Care also views the topic in different environmental conditions such as the natural habitat of an animal and animals kept in laboratory conditions. The wide implications of infanticide mean that this book will also be useful to historians, anthropologists, sociologists and psychologists.
Sexual combat is not a monopoly of the human species. As Sarah Blaffer Hrdy argues in this spellbinding book, war between male and female animals has deep roots in evolutionary history. Her account of family life among hanuman langurs--the black-faced, gray monkeys inhabiting much of the Indian subcontinent--is written with force, wit, and at times, sorrow. Male hanumans, in pursuit of genetic success, routinely kill babies sired by their competitors. The mothers of endangered infants counter with various strategems to deceive the males and prevent destruction of their own offspring. Competition and selfishness are dominant themes of langur society. Competition among males for access to females, competition among females for access to food resources, and disregard by one female for the well-being of another's infant--these are some very common examples. Yet there are also moments of heroic self-sacrifice, as when an elderly female rushes to defend her troop and its babies from an invading, infancticidal male. The Langurs of Abu is the first book to analyze behavior of wild primates from the standpoint of both sexes. It is also a poignant and sophisticated exploration of primate behavior patterns from a feminist point of view. This book may inspire controversy; it will certainly be read with pleasure by anyone interested in animal behavior. Richly illustrated with photographs, seven in full color.
This monograph presents a detailed report on the social behaviour and ecology of a previously little known species, the capped langur (presbytis pileata). The author observed capped langurs at Madhupur National Park in Bangladesh, where they live in small one-male groups. This account of his 15-month field study focuses on the relationships among one-male groups and the influence of ecology and seasonal variation in diet upon social behaviour. patterns and aspects of intra-group and intergroup behaviour, whch are then used to test predictions of traditional ecological models of primate social systems. Features of the capped langur's behaviour and ecology that differ from previously studied colobine monkeys are also described in detail.
One of the most obvious changes that has occurred in behavioural biology in recent years is that it has become conspicuously a problem orientated subject. Moreover, one of the most impor tant consequences of this has been to stimulate interdisciplinary links between evolutionary biology, zoology, ecology, anthro pology and psychology. The time is now right to ask questions which relate whole animals in the contexts of their ecosystems, with their social behaviour and development, with their perceptual and cog nitive capacities. These are new ways of looking at old problems, but we are still at the stage of finding out what kinds of questions to ask. For several years now I have been involved in teaching behavioural biology to students of psychology as well as zoology, and have greatly appreciated the opportunity to relate material across many different subject areas. It is the interfacing of prob lems, as in ecology and psychology for example, that makes 'more sense' of topics such as 'intelligence', responses to 'novelty', feeding strategies and socialleaming. The aim of the book is to provide readily digestible information in a number of areas of current interest in behavioural biology. Above all, it is intended to provide a basis for discussion and further inquiry.
Recent field studies of a variety of mammalian species reveal a surprisingly high frequency of infanticide - the killing of unweaned or otherwise maternally dependent offspring. Similarly, studies of birds, fish, amphibians, and invertebrates demonstrate egg and larval mortality in these species, a phenomenon directly analogous to infanticide in mammals. In this collection, Hausfater and Hrdy draw together work on animal and human infanticide and place these studies in a broad evolutionary and comparative perspective.Infanticide presents the theoretical background and taxonomic distribution of infanticide, infanticide in nonhuman primates, infanticide in rodents, and infanticide in humans. It examines closely sex allocation and sex ratio theory, surveys the phylogeny of mammalian interbirth intervals, and reviews data on sources of egg and larval mortality in a variety of invertebrate and lower vertebrate species. Dealing with infanticide in nonhuman primates, two chapters critically examine data on infanticide in langurs and its broader theoretical implications. By reviewing sources of infant mortality in populations of small mammals and new laboratory analyses of the causes and consequences of infanticide, this work explores such issues as the ontogeny of infanticide, proximate cues of infants and females which elicit infanticidal behavior in males, the genetical basis of infanticide, and the hormonal determinants.Hausfater and Sarah Blaffer Hrdy, through their selection of materials for this book, evaluate the frequency, causes, and function of infanticide. Historical, ethnographic, and recent data on infanticide are surveyed. "Infanticide" summarizes current research on the evolutionary origins and proximate causation of infanticide in animals and man. As such it will be indispensable reading for anthropologists and behavioral biologists as well as ecologists, psychologists, demographers, and epidemiologists.
Colobine monkeys have a unique digestive system, analagous to that of ruminants, which allows them to exploit foliage as a food source. This gives them a niche in Old World forests where they are often the only abundant medium-sized arboreal folivorous mammal. From a possible Miocene origin, Colobine monkeys have radiated into a wide variety of forms inhabiting a range of tropical woodlands in Africa and Asia. Most of the extant species have been subject to long term field studies, but until this book, no synthesis of work on this group has been available. The central theme of is that of adaptive radiation, showing how the special features of colobine anatomy interacted with a range of ecosystems to produce the distinctive species of today. The book discusses parallels with other mammalian groups, and will be of relevance to workers in evolutionary ecology, primatology and tropical ecology.
Simians, Cyborgs and Women is a powerful collection of ten essays written between 1978 and 1989. Although on the surface, simians, cyborgs and women may seem an odd threesome, Haraway describes their profound link as "creatures" which have had a great destabilizing place in Western evolutionary technology and biology. Throughout this book, Haraway analyzes accounts, narratives, and stories of the creation of nature, living organisms, and cyborgs. At once a social reality and a science fiction, the cyborg--a hybrid of organism and machine--represents transgressed boundaries and intense fusions of the nature/culture split. By providing an escape from rigid dualisms, the cyborg exists in a post-gender world, and as such holds immense possibilities for modern feminists. Haraway's recent book, Primate Visions, has been called "outstanding," "original," and "brilliant," by leading scholars in the field. (First published in 1991.)
Research on parenting through the life course has developed around two separate approaches. Evolutionary biology provides fresh perspectives from life history theory using behavioral ecology and parental investment theory. At the same time, the social and behavioral sciences integrates research from long-term studies of individual development and from the collection of life histories. This path-breaking book advances evolutionary, life history research by integrating perspectives of these two approaches into a biosocial science of the life course. It examines parenthood as a commitment extending throughout life and focuses on the impact on parental and child behavior of changes in the timing, distribution, and intensity of parental investment. This perspective is particularly appropriate for research on parenting since the family is the universal human institution within which the bearing and rearing of children has been based and which transmits traditions, beliefs, and values to the young.
