Book Synopsis Mammalian Dispersal Patterns by : B. Diane Chepko-Sade
Download or read book Mammalian Dispersal Patterns written by B. Diane Chepko-Sade and published by University of Chicago Press. This book was released on 1987 with total page 361 pages. 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.

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.

Book Synopsis Mammal Societies by : Tim Clutton-Brock
Download or read book Mammal Societies written by Tim Clutton-Brock and published by John Wiley & Sons. This book was released on 2016-05-31 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.
Book Synopsis Behavioural Ecology of Western Palearctic Falcons by : Giovanni Leonardi
Download or read book Behavioural Ecology of Western Palearctic Falcons written by Giovanni Leonardi and published by Springer Nature. This book was released on 2020-12-07 with total page 214 pages. Available in PDF, EPUB and Kindle. Book excerpt: This monograph is the result of eight years of bibliographical and field research concerning several behavioural ecology aspects of the Palaearctic falcons. For a while, this book grew along with “The Lanner falcon” published in 2015 and revised in 2017. In both books the main aim was to provide a clear overview of the biology and ecology of these species. In fact in the last 20 years, the number of publications on falcons has grown tremendously and, in parallel, also those belonging to the so-called "grey literature". The number of people involved is also increased by including both academics and nature lovers. Many previously published books emphasized identification, and offered little insights on the behavioural and ecological aspects of the species. Very often, the research on behavioural ecology remains closed within the confines of academic community. By contrast, a multitude of basic data is scattered in countless articles published in local magazines. Many falcon species are easy to observe and study (such as kestrels) but others are more rare and localized. In order to understand the survival strategies adopted by this group of avian predators, it is necessary not to lose sight of the overall picture. This book tries to explain the different survival strategies by examining, through a few essential chapters, some crucial aspects for all species. The first chapter provides information on the genus Falco, its genetics, evolution and morphological peculiarities. The other chapters deal with reproductive strategies, competition, exploitation of resources, dispersal patterns, communication and sociality. One of the main objectives of this book is to produce an accessible but scholarly curated source of reference. By understanding the most common species, it is possible to provide a working framework for rarer, and especially threatened, falcon species.

Download or read book Sociality in Bats written by Jorge Ortega and published by Springer. This book was released on 2016-06-07 with total page 301 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides new insights into the social behavior of bats - one of the most fascinating topics currently being pursued by researchers. After an introduction reviewing the history of research in bat behavioral ecology, it covers three major themes: bat sociality per se (Part I), bat communication (Part II), and ecological aspects (Part III). Part I offers a concise overview of the social organization and systems of bats, introducing readers to the complexity and dynamics of group structures. Part II is devoted to the innovative field of social communication, focusing on bat songs, dialects and calls. Part III discusses the influence of the environment on bat behavior, particularly with regard to roosting and foraging. This book addresses the needs of researchers working in behavioral sciences, evolution and ecology.
Book Synopsis Dispersing Primate Females by : Takeshi Furuichi
Download or read book Dispersing Primate Females written by Takeshi Furuichi and published by . This book was released on 2015 with total page 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.

Book Synopsis Reproduction in Mammals by : Virginia Hayssen
Download or read book Reproduction in Mammals written by Virginia Hayssen and published by JHU Press. This book was released on 2017-10-27 with total page 369 pages. Available in PDF, EPUB and Kindle. Book excerpt: A fascinating look at the diverse reproductive strategies of numerous female mammals, from hyenas to goats, kangaroos to whales. Newborn mammals can weigh as little as a dime or as much as a motorcycle. Some receive milk for only a few days, whereas others nurse for years. Humans typically have only one baby at a time following nine months of pregnancy, but other mammals have twenty or more young after only a few weeks in utero. What causes this incredible reproductive diversity? In Reproduction in Mammals, Virginia Hayssen and Teri J. Orr present readers with a fascinating examination of the varied reproductive strategies of a broad spectrum of mammals, from marsupials to whales. This unique book's comprehensive coverage gathers stories from many taxa into a single, cohesive perspective that centers on the reproductive lives of females. The authors shed light on a number of intriguing questions, including • do bigger moms have bigger babies? • do primates have longer pregnancies than other groups? • does habitat influence animals' reproductive patterns? • do carnivores typically produce larger litters than prey species? The book opens with the authors' definition of what constitutes a female perspective and an examination of the evolution of reproduction in mammals. It then outlines the typical individual mammalian female: her genetics, anatomy, and physiology. Taking a nuanced approach, Hayssen and Orr describe the female reproductive cycle and explore female mammals' interactions with males and offspring. Readers will come away from this thought-provoking book with an understanding of not only how reproduction fits into the lives of female mammals but also how biology has affected the enormously diverse reproductive patterns of the phenotypes we observe today.
