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: Serengeti II: Dynamics, Management, and Conservation of an Ecosystem brings together twenty years of research by leading scientists to provide the most most thorough understanding to date of the spectacular Serengeti-Mara ecosystem in East Africa, home to one of the largest and most diverse populations of animals in the world. Building on the groundwork laid by the classic Serengeti: Dynamics of an Ecosystem, published in 1979 by the University of Chicago Press, this new book integrates studies of the ecosystem at every level—from the plants at the bottom of the visible food chain, to the many species of herbivores and predators, to the system as a whole. Drawing on new data from many long-term studies and from more recent research initiatives, and applying new theory and computer technology, the contributors examine the large-scale processes that have produced the Serengeti's extraordinary biological diversity, as well as the interactions among species and between plants and animals and their environment. They also introduce computer modeling as a tool for exploring these interactions, employing this new technology to test and anticipate the effects of social, political, and economic changes on the entire ecosystem and on particular species, and so to shape future conservation and management strategies.

Book Synopsis Shaping Immigration News by : Rodney Benson
Download or read book Shaping Immigration News written by Rodney Benson and published by Cambridge University Press. This book was released on 2013-08-19 with total page 297 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book offers a comprehensive portrait of French and American journalists in action as they grapple with how to report and comment on one of the most important issues of our era. Drawing on interviews with leading journalists and analyses of an extensive sample of newspaper and television coverage since the early 1970s, Rodney Benson shows how the immigration debate has become increasingly focused on the dramatic, emotion-laden frames of humanitarianism and public order. In both countries, less commercialized media tend to offer the most in-depth, multi-perspective and critical news. Benson challenges classic liberalism's assumptions about state intervention's chilling effects on the press, suggests costs as well as benefits to the current vogue in personalized narrative news, and calls attention to journalistic practices that can help empower civil society. This book offers new theories and methods for sociologists and media scholars and fresh insights for journalists, policy makers and concerned citizens.
Book Synopsis Emigrant Worlds and Transatlantic Communities by : Elizabeth Jane Errington
Download or read book Emigrant Worlds and Transatlantic Communities written by Elizabeth Jane Errington and published by McGill-Queen's Press - MQUP. This book was released on 2007-10-16 with total page 256 pages. Available in PDF, EPUB and Kindle. Book excerpt: Emigrant Worlds and Transatlantic Communities gives voice to the Irish, Scottish, English, and Welsh women and men who negotiated the complex and often dangerous world of emigration between 1815 and 1845. Using "information wanted" notices that appeared in colonial newspapers as well as emigrants' own accounts, Errington illustrates that emigration was a family affair. Individuals made their decisions within a matrix of kin and community - their experiences shaped by their identities as husbands and wives, parents and children, siblings and cousins. The Atlantic crossing divided families, but it was also the means of reuniting kin and rebuilding old communities. Emigration created its own unique world - a world whose inhabitants remained well aware of the transatlantic community that provided them with a continuing sense of identity, home, and family.

Book Synopsis The African Wild Dog by : Scott Creel
Download or read book The African Wild Dog written by Scott Creel and published by Princeton University Press. This book was released on 2019-12-31 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: With only 5,000 surviving, the African wild dog (Lycaon pictus) is one of the world's most endangered large carnivores--and one of the most remarkable. This comprehensive portrait of wild dogs incorporates previously scattered information with important new findings from a six-year study in Tanzania's Selous Game Reserve, Africa's largest protected area. The book emphasizes ecology, concentrating on why wild dogs fare poorly in protected areas that maintain healthy populations of lions, hyenas, or other top carnivores. In addition to conservation issues, it covers fascinating aspects of wild dog behavior and social evolution. The Creels use demographic, behavioral, endocrine, and genetic approaches to examine how and why nonbreeding pack mates help breeding pairs raise their litters. They also present the largest data set ever collected on mammalian predator-prey interactions and the evolution of cooperative hunting, allowing them to account for wild dogs' prowess as hunters. By using a large sample size and sophisticated analytical tools, the authors step well beyond previous research. Their results include some surprises that will cause even specialists to rethink certain propositions, such as the idea that wild dogs are unusually vulnerable to infectious disease. Several findings apply broadly to the management of other protected areas. Of clear appeal to ecologists studying predation and cooperation in any population, this book collects and expands a cache of information useful to anyone studying conservation as well as to amateurs intrigued by the once-maligned but extraordinary wild dog.

Book Synopsis The Social Gene by : Anthony Caswell
Download or read book The Social Gene written by Anthony Caswell and published by FriesenPress. This book was released on 2016-10-11 with total page 145 pages. Available in PDF, EPUB and Kindle. Book excerpt: The hypothesis of animal interactions, known as kin selection or the selfish gene, proposes that only blood relatives are capable of forming herds and engaging in unselfish acts with each other. While this may satisfy the expectations of many evolutionists, the animals themselves frequently do not adhere to this restriction. There are several examples of animals in the wild assisting unrelated individuals at a cost to themselves and many also form colonies that contain unrelated individuals. In this monograph the author proposes a modification to the theory that renders the restriction of kin selection altogether unnecessary. Instead, he argues that the genes of animals that control social interactions, do not give instructions at all, but nudge the animals through combinations of rewards and penalties towards their best long-term interests in accord with the principles of Darwinian evolution. This exposition has been built on the many excellent published observations and experiments of researchers in the field and in the laboratory. It accounts for all general types of sociality of animals and humans including passive sociality, social exchange, sexual segregation, dispersal, adoption, mutual support, cooperation, altruism and human homosexuality.

Book Synopsis The World Rushed In by : J. S. Holliday
Download or read book The World Rushed In written by J. S. Holliday and published by University of Oklahoma Press. This book was released on 2015-03-16 with total page 577 pages. Available in PDF, EPUB and Kindle. Book excerpt: When The World Rushed In was first published in 1981, the Washington Post predicted, “It seems unlikely that anyone will write a more comprehensive book about the Gold Rush.” Twenty years later, no one has emerged to contradict that judgment, and the book has gained recognition as a classic. As the San Francisco Examiner noted, “It is not often that a work of history can be said to supplant every book on the same subject that has gone before it.” Through the diary and letters of William Swain--augmented by interpolations from more than five hundred other gold seekers and by letters sent to Swain from his wife and brother back home--the complete cycle of the gold rush is recreated: the overland migration of over thirty thousand men, the struggle to “strike it rich” in the mining camps of the Sierra Nevadas, and the return home through the jungles of the Isthmus of Panama. In a new preface, the author reappraises our continuing fascination with the “gold rush experience” as a defining epoch in western--indeed, American--history.
