Adaptation and Fitness in Animal Populations available in PDF, EPUB and Kindle. Fitness and adaptation are fundamental characteristics of plant and animal species, enabling them to survive in their environment and to adapt to the inevitable changes in this environment. This is true for both the genetic resources of natural ecosystems as well as those used in agricultural production. Extensive genetic variation exists between varieties/breeds in a species and amongst individuals within breeds. This variation has developed over very long periods of time. A major ongoing challenge is how to best utilize this variation to meet short-term demands whilst also conserving it for longer-term possible use. Many animal breeding programs have led to increased performance for production traits but this has often been accompanied by reduced fitness. In addition, the global use of genetic resources prompts the question whether introduced genotypes are adapted to local production systems. Understanding the genetic nature of fitness and adaptation will enable us to better manage genetic resources allowing us to make efficient and sustainable decisions for the improvement or breeding of these resources. This book had an ambitious goal in bringing together a sample of the world’s leading scientists in animal breeding and evolutionary genetics to exchange knowledge to advance our understanding of these vital issues.

This book was released on 2013-10-22. Animals and Environmental Fitness: Physiological and Biochemical Aspects of Adaptation and Ecology available in PDF, EPUB and Kindle. Animals and Environmental Fitness: Physiological and Biochemical Aspects of Adaptation and Ecology, Volume 2 contains the proceedings of the First Conference of the European Society for Comparative Physiology and Biochemistry held in Liège, Belgium, on August 27-31, 1979. The papers explore the physiology and biochemistry of animal adaptation and ecology and cover topics ranging from amino acid transport and metabolism during osmotic shock to the role of organic compounds in osmoregulation in plants and animals. This volume is comprised of 89 chapters and begins with an analysis of the transport and metabolism of amino acids under osmotic stress, followed by a discussion on cell volume regulation in isolated heart ventricles from the flounder, Platichthys flesus, perfused with anisosmotic media. Subsequent chapters focus on the effects of cholinergic drugs on the osmotic fragility of erythrocytes; strategies of osmoregulation in the fiddler crab Uca pugilator; ionic regulation in the African catfish Clarias mossambicus in water and air; and environmental and endocrine factors controlling osmotic water fluxes in gills of Sarotherodon (tilapia) mossambicus. The effect of seawater adaptation on the phosphatidyl-choline metabolism in the eel is also considered, along with evaporative water loss in anuran amphibians. This book will be of value to zoologists, physiologists, biologists, and biochemists.

Adaptation and Natural Selection available in PDF, EPUB and Kindle. Biological evolution is a fact—but the many conflicting theories of evolution remain controversial even today. When Adaptation and Natural Selection was first published in 1966, it struck a powerful blow against those who argued for the concept of group selection—the idea that evolution acts to select entire species rather than individuals. Williams’s famous work in favor of simple Darwinism over group selection has become a classic of science literature, valued for its thorough and convincing argument and its relevance to many fields outside of biology. Now with a new foreword by Richard Dawkins, Adaptation and Natural Selection is an essential text for understanding the nature of scientific debate.

Download and read online ebook Adaptation in Metapopulations write by Michael J. Wade. This book was released on 2016-05-03. Adaptation in Metapopulations available in PDF, EPUB and Kindle. Across the globe, populations of plants and animals live in clusters, but maintain a connectivity a population of populations. There are naturally occurring metapopulations, such as clusters of groupers spread across coral reefs, and there are metapopulations humans have helped create by fragmenting landscapes: stands of trees separated by roads, prairies separated by agricultural farms. As the dynamics of landscape change have accelerated, and understanding of how metapopulations functions has played a critical role in ecology and evolutionary biology. Adaptation in Metapopulations synthesizes the role of genetic interactions in adaptive evolution and their influence on the effectiveness of different types of selection. Drawing on extensive field work and lab experiments, cohered with a strong conceptual arc, the work also integrates molecular and organismal biology, as Wade explores adaptation at multiple scales, and shows how evolutionary dynamics scale from the gene to the metapopulation.

Animals and Environmental Fitness, Volume 1: Invited Lectures is a collection of papers that tackles ecological concerns. The materials of the book are organized according the main issue of their contents. The text first tackles the chemical factors of the environment, such as water and oxygen availability, ecomones, and pollutants. The other half of the book encompasses the physical factors of the environment that include light, pressure, and temperature. The text will be of great use to scientists who study the interaction between flora, fauna, and the total environment.
