Available in PDF, EPUB and Kindle. Book excerpt: Mammalian Dispersal Patterns examines the ways that social structure affects population genetics and, in turn, rates of evolution, in mammalian groups. It brings together fieldwork in animal behavior and wildlife biology with theoretical work in demography and population genetics. The focus here is dispersal—whether, how, and when individuals leave the areas where they are born. Theoretical work in population genetics indicates that such social factors as skewed sex ratios, restrictive mating patterns, and delayed age of first reproduction will lower the reproductive variability of a population by reducing the number of genotypes passed from one generation to the next. Field studies have shown that many mammalian species do exhibit many such social characteristics. Among horses, elephant seals, and a number of primates, the majority of females are inseminated by only a fraction of the males. In pacts of wolves and mongooses, usually only the highest-ranking male and female breed in a given season. Although socially restricted mating tends to lower genetic variability in isolated populations, it actually tends to increase genetic variability in subdivided populations with low rates of migration between subunits. Among some species there is little dispersal and thus little gene flow between subpopulations; other species travel far afield before mating. The contributors to this volume examine actual data from populations of mammals, the way patterns of dispersal correlate with the genetic structure of individuals and populations, and mathematical models of population structure. This interdisciplinary approach has an important bearing on work in conservation of both wildlife and zoo populations, for it shows that the home range and the population size needed to maintain genetic variability can differ greatly from one species to the next. The volume also offers a fruitful model for future research.
Download or read book Animal Dispersal written by N.C. Stenseth and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 359 pages. Available in PDF, EPUB and Kindle. Book excerpt: 4.1.1 Demographic significance Confined populations grow more rapidly than populations from which dispersal is permitted (Lidicker, 1975; Krebs, 1979; Tamarin et at., 1984), and demography in island populations where dispersal is restricted differs greatly from nearby mainland populations (Lidicker, 1973; Tamarin, 1977, 1978; Gliwicz, 1980), clearly demonstrating the demographic signi ficance of dispersal. The prevalence of dispersal in rapidly expanding populations is held to be the best evidence for presaturation dispersal. Because dispersal reduces the growth rate of source populations, it is generally believed that emigration is not balanced by immigration, and that mortality of emigrants occurs as a result of movement into a 'sink' of unfavourable habitat. If such dispersal is age- or sex-biased, the demo graphy of the population is markedly affected, as a consequence of differ ences in mortality in the dispersive sex or age class. Habitat heterogeneity consequently underlies this interpretation of dispersal and its demographic consequences, although the spatial variability of environments is rarely assessed in dispersal studies.

Download or read book The Evolution of Social Behaviour written by Michael Taborsky and published by Cambridge University Press. This book was released on 2021-08-26 with total page 446 pages. Available in PDF, EPUB and Kindle. Book excerpt: How can the stunning diversity of social systems and behaviours seen in nature be explained? Drawing on social evolution theory, experimental evidence and studies conducted in the field, this book outlines the fundamental principles of social evolution underlying this phenomenal richness.To succeed in the competition for resources, organisms may either 'race' to be quicker than others, 'fight' for privileged access, or 'share' their efforts and gains. The authors show how the ecology and intrinsic attributes of organisms select for each of these strategies, and how a handful of straightforward concepts explain the evolution of successful decision rules in behavioural interactions, whether among members of the same or different species. With a broad focus ranging from microorganisms to humans, this is the first book to provide students and researchers with a comprehensive account of the evolution of sociality by natural selection.
Download or read book A Critical Theology of Genesis written by Itzhak Benyamini and published by Springer. This book was released on 2016-10-01 with total page 169 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this book Itzhak Benyamini presents an alternative reading of Genesis, a close textual analysis from the story of creation to the binding of Isaac. This reading offers the possibility of a soft relation to God, not one characterized by fear and awe. The volume presents Don-Abraham-Quixote not as a perpetual knight of faith but as a cunning believer in the face of God's demands of him. Benyamini reads Genesis without making concessions to God, asking about Him before He examines the heart of Adam, Noah, Abraham, and the other knights of faith (if they are really that). In this way, the commentary on Genesis becomes a platform for a new type of critical theology. Through this unconventional rereading of the familiar biblical text, the book attempts to extract a different ethic, one that challenges the Kierkegaardian demand of blind faith in an all-knowing moral God and offers in its stead an alternative, everyday ethic. The ethic that Benyamini uncovers is characterized by family continuity and tradition intended to ensure that very axis—familial permanence and resilience in the face of the demanding and capricious law of God and the everyday hardships of life.
Download or read book Dispersing Primate Females written by Takeshi Furuichi and published by Springer. This book was released on 2015-06-05 with total page 303 pages. Available in PDF, EPUB and Kindle. Book excerpt: Why do females in male-philopatric species seem to show larger variation in their life history strategies than males in female-philopatric species? Why did females in human societies come to show enormous variation in the patterns of marriage, residence and mating activities? To tackle these important questions, this book presents the latest knowledge about the dispersing females in male-philopatric non-human primates and in human societies. The non-human primates that are covered include muriquis, spider monkeys, woolly monkeys, gorillas, chimpanzees, bonobos and some species of colobine monkeys. In these non-human primate species females typically leave their natal group before sexual maturation and start reproduction in other groups into which they immigrate. However, there is a large variation as some females may breed in their natal group with some risks of inbreeding with their male relatives and some females may associate with males of multiple groups at the same time after leaving their natal group. Such variation seems to provide better strategies for reproduction depending on local circumstances. Although knowledge about female dispersal patterns and life history is indispensable for understanding the dynamic structure of primate societies, it is still not known how females behave after leaving their natal groups, how many groups they visit before finally settling down and which kinds of groups they choose to immigrate into, due to the large variation and flexibility and the difficulty of tracking females after natal dispersal. To encourage further progress in this important field, this volume provides new insights on evolution of female dispersal by describing factors influencing variations in the dispersal pattern across primates and a hypothesis for the formation of human families from the perspectives of female life history. This book is recommended reading for researchers and students in primatology, anthropology, animal behavior and evolution and for anyone interested in primate societies and human evolution.
Download or read book Notes on the Elements of Behavioral Science written by Doris Zumpe and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 352 pages. Available in PDF, EPUB and Kindle. Book excerpt: These notes are intended to help undergraduates who need to understand something of behavior both for its intrinsic interest and for their future careers in medicine, biology, psychology, anthropology, veterinary medicine, and nursing. In Emory University's Biology Department, a single-semester course called Evolutionary Perspectives on Behavior is given to undergraduates. It amounts to four, not eight months of study, so a great deal of compression is essential. There are several excellent textbooks available that deal with behavioral science from different perspectives, but we have found them too compendious for use in a short course when students are so heavily burdened; it is unsatisfactory to direct them to a chapter here and there in several different books or to this or that review article and original paper. In this volume, we have tried effectively and inexpensively to put in one place what we know is needed. The topics we have selected deal with their subjects in a simple, straightforward way without being too superficial. We could not cover everything and the gaps are not entirely idiosyncratic but reflect what students are given very well in other courses. Thus, there is no mention of the physiology of the axon and synapse; learning, memory, cognition, and basic genetics are hardly touched upon because students know about these matters from elsewhere.
Download or read book Kinship and Behavior in Primates written by Bernard Chapais and published by Oxford : Oxford University Press. This book was released on 2004-03-04 with total page 520 pages. Available in PDF, EPUB and Kindle. Book excerpt: Annotation This book presents a series of review chapters on the various aspects of primate kinship and behavior. The relatively new molecular data allow one to assess directly degrees of genetic relatedness and kinship relations between individuals. A considerable body of data on intergroup variation, based on experimental studies in both free-ranging and captive groups has accumulated. This allows a full and satisfying reconsideration of this broad area of research.
Download or read book The Biology and Conservation of Wild Canids written by David W. Macdonald and published by OUP Oxford. This book was released on 2004-06-24 with total page 464 pages. Available in PDF, EPUB and Kindle. Book excerpt: No group of wild mammals so universally captures the emotions of people world-wide than do wild canids. That emotion can be enchantment and fascination, but it can also be loathing, because the opportunism that is the hallmark of the dog family also leads them into conflict with humans. In the developed world at least, the fascination with wild canids doubtless stems from people's captivation with domestic dogs - everybody feels they are an expert on canids! While most people may be familiar with only the better known members of the dog family, such as the grey wolf and the red fox, there are in fact 36 species of wolves, dogs, jackals and foxes. They attract hugely disproportionate interest from academics, conservationists, veterinarians, wildlife managers and the general public. This book brings together in single volume an astonishing synthesis of research done in the last twenty years and is the first truly compendious synthesis on wild canids. Beginning with a complete account of all 36 canid species, there follow six review chapters that emphasise topics most relevant to canid conservation science, including evolution and systematics, behavioural ecology, population genetics, diseases, conflict/control of troublesome species, and conservation tools. Fifteen detailed case studies then delve deeply into the very best species investigations currently available written by all the leading figures in the field. Much of the material is previously unpublished and will make fascinating reading far beyond the confines of canid specialists. These chapters portray the unique attributes of wild canids, their fascinating (and conflictive) relationship with man, and suggestions for future research and conservation measures for the Canidae. While most canid species are widespread and thrive in human dominated landscapes, several are in severe jeopardy; habitat loss, illegal hunting, persecution by farmers and disease all imperil dwindling populations. A final chapter analyses the requirements of, and approaches to, practical conservation, with lessons that go far beyond the dog family. It concentrates particular attention on priorities for the protection of the most threatened canid species, including the red wolf, African wild dog, Ethiopian wolf, Island fox and Darwin's fox. The wild canids provide examples that will thrill the evolutionary biologists and theoretician, enthral the natural historian and challenge the conservationist and wildlife manager. Anybody interested in evolutionary and behavioural biology, in mammals, in the environment, or in conservation will find much that is new and enriching in this book.
Download or read book Mammal Societies written by Tim Clutton-Brock and published by John Wiley & Sons. This book was released on 2016-04-20 with total page 760 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book aims to integrate our understanding of mammalian societies into a novel synthesis that is relevant to behavioural ecologists, ecologists, and anthropologists. It adopts a coherent structure that deals initially with the characteristics and strategies of females, before covering those of males, cooperative societies and hominid societies. It reviews our current understanding both of the structure of societies and of the strategies of individuals; it combines coverage of relevant areas of theory with coverage of interspecific comparisons, intraspecific comparisons and experiments; it explores both evolutionary causes of different traits and their ecological consequences; and it integrates research on different groups of mammals with research on primates and humans and attempts to put research on human societies into a broader perspective.
Download or read book Cats in Australia written by Chris Dickman and published by CSIRO PUBLISHING. This book was released on 2019-06-01 with total page 344 pages. Available in PDF, EPUB and Kindle. Book excerpt: Across the world, cats are loved as pets or are kept or tolerated for their role in controlling some animal pests. But cats, both pets and feral, also kill many native animals and this toll can be enormous. Cats have been remarkably successful in Australia, spreading pervasively across the continent and many islands, occurring in all environments, and proving to be adept and adaptable hunters. A large proportion of Australia’s distinctive fauna is threatened and recent research highlights the significant role that cats play in the decline and extinction of native species. Cats in Australia brings this research together, documenting the extent to which cats have subverted, and are continuing to subvert, Australia’s biodiversity. But the book does much more than spotlight the impacts of cats on Australian nature. It describes the origins of cats and their global spread, their long-standing and varying relationship with people, their global impacts and their ecology. It also seeks to describe the challenge of managing cats, and the options available to constrain their impacts.
