Available in PDF, EPUB and Kindle. Book excerpt: In 1984, a conference called Wildlife 2000: Modeling habitat relationships of terrestrial vertebrates, was held at Stanford Sierra Camp at Fallen Leaf Lake in the Sierra Nevada Mountains of California. The conference was well-received, and the published volume (Verner, J. , M. L. Morrison, and C. J. Ralph, editors. 1986. Wildlife 2000: modeling habitat relationships of terrestrial vertebrates, University of Wisconsin Press, Madison, Wisconsin, USA) proved to be a landmark publication that received a book award by The Wildlife Society. Wildlife 2001: populations was a followup conference with emphasis on the other major biological field of wildlife conservation and management, populations. It was held on July 29-31, 1991, at the Oakland Airport Hilton Hotel in Oakland, California, in accordance with our intent that this conference have a much stronger international representation than did Wildlife 2000. The goal of the conference was to bring together an international group of specialists to address the state of the art in wildlife population dynamics, and set the agenda for future research and management on the threshold of the 21st century. The mix of specialists included workers in theoretical, as well as practical, aspects of wildlife conservation and management. Three general sessions covered methods, modelling, and conservation of threatened species.

Available in PDF, EPUB and Kindle. Book excerpt: The first International Conference on the Biology of Deer Production was held at Dunedin, New Zealand in 1983. That meeting provided, for the first time, a forum for those with interests in either wild deer management or farmed deer production to come together. Scientists, wild deer managers, domestic deer farmers, veterinarians, venison and antler product producers, and others were able to discuss common problems and to share their knowledge and experience. The relationships formed at that meeting, and the information amassed in the resulting Proceedings, sparked new endeavors in cervid research, management, and production. A great deal has taken place in the world of deer biology since 1983. Wild deer populations, although ever increasing in many areas of the world, face new hazards of habitat loss, environmental contamination, and overexploitation. Some species are closer to extinction than ever. Game managers often face political as well as biological challenges. Many more deer are now on farms, leading to greater concerns about disease control and increased needs for husbandry information. Researchers have accumulated considerable new in formation, some of it in areas such as biochemical genetics, not discussed in 1983.

Available in PDF, EPUB and Kindle. Book excerpt: The incorporation of molecular methods in ecological research has added an exciting new dimension to conventional studies, and opened windows into previously intractable areas of research, at the interface between ecology and genetics. Using these new methods it has now become routine to use genetic markers to study ecological phenomena, from molecular sexing of individuals and parentage of offspring, through to population structure of species and phylogenetic relationships of taxa. These methods have stimulated an explosion of empirical and analytical developments in molecular ecology, which have in turn, increasingly attracted students and professional biologists eager to employ them in their studies. Molecular Methods in Ecology traces the development of molecular ecology by reviewing basic molecular biological techniques and earlier methods such as protein electrophoresis, DNA-DNA hybridisation, restriction analysis of DNA, and DNA fingerprinting. Later chapters review methods using newer classes of markers such as microsatellites, introns, MHC, SSRs and AFLP markers in plants and molecular sexing in animals. The strengths and limitations of methods are discussed and guidance is provided in selecting the most appropriate methods for particular problems in ecology. This book will provide both postgraduates and researchers with a guide to choosing and employing appropriate methodologies for successful research in the field of molecular ecology. Provides up-to-date summaries of the latest molecular approaches in this rapidly expanding field. Gives guidance on the appropriate choice of methods for particular problems in ecology, and their strengths and limitations. Provides brief laboratory protocols for each molecular method and summaries of software available for analysis of data in molecular ecology. Outlines examples of the latest research results from studies of both plants and animals, integrated within the framework of molecular ecology.
Download or read book Evolutionary Quantitative Genetics written by Derek A. Roff and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 503 pages. Available in PDF, EPUB and Kindle. Book excerpt: The impetus for this book arose out of my previous book, The Evolution of Life Histories (Roff, 1992). In that book I presented a single chapter on quanti tative genetic theory. However, as the book was concerned with the evolution of life histories and traits connected to this, the presence of quantitative genetic variation was an underlying theme throughout. Much of the focus was placed on optimality theory, for it is this approach that has proven to be extremely successful in the analysis of life history variation. But quantitative genetics cannot be ig nored, because there are some questions for which optimality approaches are inappropriate; for example, although optimality modeling can address the ques tion of the maintenance of phenotypic variation, it cannot say anything about genetic variation, on which further evolution clearly depends. The present book is, thus, a natural extension of the first. I have approached the problem not from the point of view of an animal or plant breeder but from that of one interested in understanding the evolution of quantitative traits in wild populations. The subject is large with a considerable body of theory: I generally present the assumptions underlying the analysis and the results, giving the relevant references for those interested in the intervening mathematics. My interest is in what quantitative genetics tells me about evolutionary processes; therefore, I have concentrated on areas of research most relevant to field studies.

Book excerpt: The highly publicized obscenity trial of Radclyffe Hall's The Well of Loneliness (1928) is generally recognized as the crystallizing moment in the construction of a visible modern English lesbian culture, marking a great divide between innocence and deviance, private and public, New Woman and Modern Lesbian. Yet despite unreserved agreement on the importance of this cultural moment, previous studies often reductively distort our reading of the formation of early twentieth-century lesbian identity, either by neglecting to examine in detail the developments leading up to the ban or by framing events in too broad a context against other cultural phenomena. Fashioning Sapphism locates the novelist Radclyffe Hall and other prominent lesbians -- including the pioneer in women's policing, Mary Allen, the artist Gluck, and the writer Bryher -- within English modernity through the multiple sites of law, sexology, fashion, and literary and visual representation, thus tracing the emergence of a modern English lesbian subculture in the first two decades of the twentieth century. Drawing on extensive new archival research, the book interrogates anew a range of myths long accepted without question (and still in circulation) concerning, to cite only a few, the extent of homophobia in the 1920s, the strategic deployment of sexology against sexual minorities, and the rigidity of certain cultural codes to denote lesbianism in public culture.

This book was released on 1997-11-27 with total page 306 pages. Available in PDF, EPUB and Kindle. Book excerpt: Why does nature love symmetry? In Asymmetry, Developmental Stability and Evolution, M--oslash--;ller and Swaddle analyse the evolutionary implications of symmetry. They advance and explain their theory that asymmetry is related to genetic stability and fitness, and that symmetric individuals appear to have quantifiable and significant advantages over their asymmetric counterparts. When assessing potential mates or competitors, animals may be able to use symmetry as an honest indication of quality. This interdisciplinary book, with its associated Web-site, will be of interest to students and researchers in the fields of ecology, evolutionary biology, genetics, and animal behaviour. - ;Why does nature love symmetry?

Download or read book The Natural History of Inbreeding and Outbreeding written by Nancy Wilmsen Thornhill and published by University of Chicago Press. This book was released on 1993-08-15 with total page 583 pages. Available in PDF, EPUB and Kindle. Book excerpt: Inbreeding, the mating of close kin, and outbreeding, the mating of distant relatives or unrelated organisms, have long been important subjects to evolutionary biologists. Inbreeding reduces genetic diversity in a population, increasing the likelihood that genetic defects will become widespread and deprive a population of the diversity it may need to cope with its environment. Most plants and animals have evolved behavioral and morphological mechanisms to avoid inbreeding. However, today many endangered species exist only in small, very isolated populations where inbreeding is unavoidable, so it has become a concern for conservationists. In this volume, twenty-six experts in evolution, behavior, and genetics examine the causes and consequences of inbreeding. The authors ask whether inbreeding is as problematic as biologists have thought, under what ecological conditions inbreeding occurs, and whether organisms that inbreed have mechanisms to dampen the anticipated problems of reduced genetic variation. The studies, including theoretical and empirical work on wild and captive populations, demonstrate that many plants and animals inbreed to a greater extent than biologists have thought, with variable effects on individual fitness. Graduate students and researchers in evolutionary biology, animal behavior, ecology, and conservation biology will welcome this wide-ranging collection.
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.
