Book Synopsis Geographical Genetics (MPB-38) by : Bryan K. Epperson
Download or read book Geographical Genetics (MPB-38) written by Bryan K. Epperson and published by Princeton University Press. This book was released on 2003-08-31 with total page 372 pages. Available in PDF, EPUB and Kindle. Book excerpt: Population genetics has made great strides in applying statistical analysis and mathematical modeling to understand how genes mutate and spread through populations over time. But real populations also live in space. Streams, mountains, and other geographic features often divide populations, limit migration, or otherwise influence gene flow. This book rigorously examines the processes that determine geographic patterns of genetic variation, providing a comprehensive guide to their study and interpretation. Geographical Genetics has a unique focus on the mathematical relationships of spatial statistical measures of patterns to stochastic processes. It also develops the probability and distribution theory of various spatial statistics for analysis of population genetic data, detailing exact methods for using various spatial features to make precise inferences about migration, natural selection, and other dynamic forces. The book also reviews the experimental literature on the types of spatial patterns of genetic variation found within and among populations. And it makes an unprecedented strong connection between observed measures of spatial patterns and those predicted theoretically. Along the way, it introduces readers to the mathematics of spatial statistics, applications to specific population genetic systems, and the relationship between the mathematics of space-time processes and the formal theory of geographical genetics. Written by a leading authority, this is the first comprehensive treatment of geographical genetics. It is a much-needed guide to the theory, techniques, and applications of a field that will play an increasingly important role in population biology and ecology.

Book Synopsis Populations in a Seasonal Environment by : Stephen D. Fretwell
Download or read book Populations in a Seasonal Environment written by Stephen D. Fretwell and published by Princeton University Press. This book was released on 1972-07-21 with total page 252 pages. Available in PDF, EPUB and Kindle. Book excerpt: Most organisms live in a seasonal environment. During their life cycles, some species face seasons of cold and heat, aridity and abundant rainfall, migration and stable residence, breeding and nonbreeding. Populations grow and decline as supplies of materials essential to their survival wax and wane. Such qualitative truths as these flow obviously from field observations. In this original monograph, Stephen Fretwell analyzes the highly complex interaction between a population and a regularly varying environment in an attempt to define and measure seasonality as a critical parameter in the general theory of population regulation. Concerned primarily with the size and the habitat distribution of populations, Professor Fretwell develops simple models that, when applied to specific populations, usually of birds, demonstrate the effect of seasonal variations on the regulation of populations. He maintains that seasonality, as a concept, is essential to a full understanding of environmental interaction. During the course of his exposition, the author offers several new hypotheses, including theories affecting the breeding, numbers, distribution, and diversity of wintering birds, and a theory affecting the body size of sparrows.
Book Synopsis Environmental Factors Affecting Human Health by : Ivan Uher
Download or read book Environmental Factors Affecting Human Health written by Ivan Uher and published by BoD – Books on Demand. This book was released on 2020-08-19 with total page 192 pages. Available in PDF, EPUB and Kindle. Book excerpt: Raising the average human lifespan by a decade or more will change our world. The future is not about whether this will happen; it is about what we should do when it happens. Even the most pessimistic assertions about the future of our environment are underestimating the extent of the problem. There is simply no model in which more years of life does not equate to more people and in which that does not lead to more crowding, environmental degradation, more consumption, and more waste. Hence, as we prolong life, these environmental crises will be further exacerbated. With current diets and production practices, feeding 7,6 billion people is degrading terrestrial and aquatic ecosystems, depleting water resources, and driving climate changes. The challenges of today are not just population, and it’s not just consumption, it is waste also. Thanks to things such as cars, planes, big homes, deforestation and so forth, the annual carbon dioxide emissions of an average are three times as high as it should be. It is likely that this signals that the current level of dividends is unsustainable, hence, we use and return little of value to our natural world. In our book, we address the questions related to environmental health challenges that include contamination of air, water, and soil, and car transportation. In order to better understand natural, industrial, and social-environmental hazards, we have to think of them in a broader context (i.e., physical, chemical, biological, and cultural). We hope that the presented publication gives the reader a broader perspective on the issues related to environmental health challenges in contemporary society in the coming years.

Book Synopsis Impacts of Climate Change on Range Expansion by the Mountain Pine Beetle by : Allan L. Carroll
Download or read book Impacts of Climate Change on Range Expansion by the Mountain Pine Beetle written by Allan L. Carroll and published by . This book was released on 2006 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: The mountain pine beetle, Dendroctonus ponderosae (Hopkins) (MPB), is one of the most significant sources of mortality in mature pine forests in western North America. Despite its significant distribution, the current latitudinal and elevational range of MPB in western Canada is not restricted by the availability of suitable host trees but instead has been limited by climate. It is anticipated that under global warming, former climatically hostile environments will become climatically benign, allowing MPB to significantly expand its range. This study was initiated to investigate if there has been a shift in climatically benign habitats for MPB during the past three decades, if MPB populations have expanded into these new habitats, and what may be the range of climatically benign habitats in the future.
Book Synopsis Natural Selection in the Wild. (MPB-21), Volume 21 by : John A. Endler
Download or read book Natural Selection in the Wild. (MPB-21), Volume 21 written by John A. Endler and published by Princeton University Press. This book was released on 2020-03-31 with total page 352 pages. Available in PDF, EPUB and Kindle. Book excerpt: Natural selection is an immense and important subject, yet there have been few attempts to summarize its effects on natural populations, and fewer still which discuss the problems of working with natural selection in the wild. These are the purposes of John Endler's book. In it, he discusses the methods and problems involved in the demonstration and measurement of natural selection, presents the critical evidence for its existence, and places it in an evolutionary perspective. Professor Endler finds that there are a remarkable number of direct demonstrations of selection in a wide variety of animals and plants. The distribution of observed magnitudes of selection in natural populations is surprisingly broad, and it overlaps extensively the range of values found in artificial selection. He argues that the common assumption that selection is usually weak in natural populations is no longer tenable, but that natural selection is only one component of the process of evolution; natural selection can explain the change of frequencies of variants, but not their origins.

Book Synopsis The Theory of Ecological Communities (MPB-57) by : Mark Vellend

This book was released on 2020-09-15 with total page 246 pages. Available in PDF, EPUB and Kindle. Book excerpt: A plethora of different theories, models, and concepts make up the field of community ecology. Amid this vast body of work, is it possible to build one general theory of ecological communities? What other scientific areas might serve as a guiding framework? As it turns out, the core focus of community ecology—understanding patterns of diversity and composition of biological variants across space and time—is shared by evolutionary biology and its very coherent conceptual framework, population genetics theory. The Theory of Ecological Communities takes this as a starting point to pull together community ecology's various perspectives into a more unified whole. Mark Vellend builds a theory of ecological communities based on four overarching processes: selection among species, drift, dispersal, and speciation. These are analogues of the four central processes in population genetics theory—selection within species, drift, gene flow, and mutation—and together they subsume almost all of the many dozens of more specific models built to describe the dynamics of communities of interacting species. The result is a theory that allows the effects of many low-level processes, such as competition, facilitation, predation, disturbance, stress, succession, colonization, and local extinction to be understood as the underpinnings of high-level processes with widely applicable consequences for ecological communities. Reframing the numerous existing ideas in community ecology, The Theory of Ecological Communities provides a new way for thinking about biological composition and diversity.
