Book Synopsis Evolution through Genetic Exchange by : Michael L Arnold
Download or read book Evolution through Genetic Exchange written by Michael L Arnold and published by OUP Oxford. This book was released on 2006-07-27 with total page 266 pages. Available in PDF, EPUB and Kindle. Book excerpt: Even before the publication of Darwin's Origin of Species, the perception of evolutionary change has been a tree-like pattern of diversification - with divergent branches spreading further and further from the trunk. In the only illustration of Darwin's treatise, branches large and small never reconnect. However, it is now evident that this view does not adequately encompass the richness of evolutionary pattern and process. Instead, the evolution of species from microbes to mammals builds like a web that crosses and re-crosses through genetic exchange, even as it grows outward from a point of origin. Some of the avenues for genetic exchange, for example introgression through sexual recombination versus lateral gene transfer mediated by transposable elements, are based on definably different molecular mechanisms. However, even such widely different genetic processes may result in similar effects on adaptations (either new or transferred), genome evolution, population genetics, and the evolutionary/ecological trajectory of organisms. For example, the evolution of novel adaptations (resulting from lateral gene transfer) leading to the flea-borne, deadly, causative agent of plague from a rarely-fatal, orally-transmitted, bacterial species is quite similar to the adaptations accrued from natural hybridization between annual sunflower species resulting in the formation of several new species. Thus, more and more data indicate that evolution has resulted in lineages consisting of mosaics of genes derived from different ancestors. It is therefore becoming increasingly clear that the tree is an inadequate metaphor of evolutionary change. In this book, Arnold promotes the 'web-of-life' metaphor as a more appropriate representation of evolutionary change in all lifeforms. This research level text is suitable for senior undergraduate and graduate level students taking related courses in departments of genetics, ecology and evolution. It will also be of relevance and use to professional evolutionary biologists and systematists seeking a comprehensive and authoritative overview of this rapidly expanding field.

Book Synopsis The Geographic Mosaic of Coevolution by : John N. Thompson
Download or read book The Geographic Mosaic of Coevolution written by John N. Thompson and published by University of Chicago Press. This book was released on 2005-06-15 with total page 457 pages. Available in PDF, EPUB and Kindle. Book excerpt: Coevolution—reciprocal evolutionary change in interacting species driven by natural selection—is one of the most important ecological and genetic processes organizing the earth's biodiversity: most plants and animals require coevolved interactions with other species to survive and reproduce. The Geographic Mosaic of Coevolution analyzes how the biology of species provides the raw material for long-term coevolution, evaluates how local coadaptation forms the basic module of coevolutionary change, and explores how the coevolutionary process reshapes locally coevolving interactions across the earth's constantly changing landscapes. Picking up where his influential The Coevolutionary Process left off, John N. Thompsonsynthesizes the state of a rapidly developing science that integrates approaches from evolutionary ecology, population genetics, phylogeography, systematics, evolutionary biochemistry and physiology, and molecular biology. Using models, data, and hypotheses to develop a complete conceptual framework, Thompson also draws on examples from a wide range of taxa and environments, illustrating the expanding breadth and depth of research in coevolutionary biology.

Book Synopsis International Advances in the Ecology, Zoogeography, and Systematics of Mayflies and Stoneflies by : F. R. Hauer
Download or read book International Advances in the Ecology, Zoogeography, and Systematics of Mayflies and Stoneflies written by F. R. Hauer and published by Univ of California Press. This book was released on 2008-06-24 with total page 426 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this volume is to encourage and facilitate focused research and provide a forum for scholarly exchange about the status of Mayfly and Stonefly science. Professor John Brittain, whose research is focused on freshwater entomology, especially egg development and life cycle strategies of Ephemeroptera and Plecoptera, presents a chapter reflecting on the quality of mayflies as good indicators of global warming and the quality of streams and lakes. Professor Emeritus Andrew Sheldon, whose interests have encompassed community and population ecology of aquatic animals over a span of more than 40 years, especially insects and fishes, explores topics of Scale and Hierarchy and the Ecology of Plecoptera, discussing how studies emphasizing scale and perspective reveal importance of stoneflies to ecosystems. Other topics cover a broad base of disciplines including morphology, physiology, phylogeny, taxonomy, ecology and conservation. The chapters have been compiled into three sections for this volume: Ecology, Zoogeography and Systematics.

Book Synopsis Amphibian Declines by : Michael Lannoo
Download or read book Amphibian Declines written by Michael Lannoo and published by Univ of California Press. This book was released on 2005-06-15 with total page 1117 pages. Available in PDF, EPUB and Kindle. Book excerpt: This benchmark volume documents in comprehensive detail a major environmental crisis: rapidly declining amphibian populations and the disturbing developmental problems that are increasingly prevalent within many amphibian species. Horror stories on this topic have been featured in the scientific and popular press over the past fifteen years, invariably asking what amphibian declines are telling us about the state of the environment. Are declines harbingers of devastated ecosystems or simply weird reflections of a peculiar amphibian world? This compendium—presenting new data, reviews of current literature, and comprehensive species accounts—reinforces what scientists have begun to suspect, that amphibians are a lens through which the state of the environment can be viewed more clearly. And, that the view is alarming and presages serious concerns for all life, including that of our own species. The first part of this work consists of more than fifty essays covering topics from the causes of declines to conservation, surveys and monitoring, and education. The second part consists of species accounts describing the life history and natural history of every known amphibian species in the United States.
Book Synopsis Islands in the Cosmos by : Dale A. Russell
Download or read book Islands in the Cosmos written by Dale A. Russell and published by Indiana University Press. This book was released on 2009-07-14 with total page 481 pages. Available in PDF, EPUB and Kindle. Book excerpt: How is it that we came to be here? The search for answers to that question has preoccupied humans for millennia. Scientists have sought clues in the genes of living things, in the physical environments of Earth from mountaintops to the depths of the ocean, in the chemistry of this world and those nearby, in the tiniest particles of matter, and in the deepest reaches of space. In Islands of the Cosmos, Dale A. Russell traces a path from the dawn of the universe to speculations about our future on this planet. He centers his story on the physical and biological processes in evolution, which interact to favor more successful, and eliminate less successful, forms of life. Marvelously, these processes reveal latent possibilities in life's basic structure, and propel a major evolutionary theme: the increasing proficiency of biological function. It remains to be seen whether the human form can survive the dynamic processes that brought it into existence. Yet the emergence of the ability to acquire knowledge from experience, to optimize behavior, to conceptualize, to distinguish "good" from "bad" behavior all hint at an evolutionary outcome that science is only beginning to understand.

Book Synopsis California Amphibian and Reptile Species of Special Concern by : Robert C. Thomson
Download or read book California Amphibian and Reptile Species of Special Concern written by Robert C. Thomson and published by Univ of California Press. This book was released on 2016-06-21 with total page 407 pages. Available in PDF, EPUB and Kindle. Book excerpt: One of the most important hotspots of herpetological biodiversity in the United States, California is home to many endemic amphibians and reptiles found nowhere else on earth. Many of these taxa have unique ecological and morphological specializations, and their management is an important conservation challenge. Increasing climate change impacts, human development, and extreme drought mean many of these species face an ever-greater risk of extinction. California Amphibian and Reptile Species of Special Concern provides an up-to-date synthesis of the current state of knowledge regarding the biology and conservation risks faced by 45 of California’s most sensitive amphibian and reptile species. With the goal of enhancing management based on the best available science, the authors developed a novel set of risk metrics to identify special concern species and the threats they face, including population declines, range size and restrictions, and ecological specializations and niche restrictions. In addition to detailed species accounts, this book provides a quantitative analysis of the conservation status and pressing management issues facing individual species and the state’s amphibian and reptile fauna as a whole. The volume focuses on identifying threats, concrete recommendations for management and recovery, and future research needs. The text is complemented by detailed distribution maps, color photos, and graphs. Written in nontechnical language, California Amphibian and Reptile Species of Special Concern will be a valuable resource to a broad range of users from resource managers, field biologists, and academic herpetologists to students and recreational naturalists. Published in association with the California Department of Fish and Wildlife.
Book Synopsis Late Pleistocene and Holocene Environmental Change on the Olympic Peninsula, Washington by : Daniel G. Gavin
Download or read book Late Pleistocene and Holocene Environmental Change on the Olympic Peninsula, Washington written by Daniel G. Gavin and published by Springer. This book was released on 2014-11-25 with total page 148 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study brings together decades of research on the modern natural environment of Washington's Olympic Peninsula, reviews past research on paleoenvironmental change since the Late Pleistocene, and finally presents paleoecological records of changing forest composition and fire over the last 14,000 years. The focus of this study is on the authors’ studies of five pollen records from the Olympic Peninsula. Maps and other data graphics are used extensively. Paleoecology can effectively address some of these challenges we face in understanding the biotic response to climate change and other agents of change in ecosystems. First, species responses to climate change are mediated by changing disturbance regimes. Second, biotic hotspots today suggest a long-term maintenance of diversity in an area, and researchers approach the maintenance of diversity from a wide range and angles (CITE). Mountain regions may maintain biodiversity through significant climate change in ‘refugia’: locations where components of diversity retreat to and expand from during periods of unfavorable climate (Keppel et al., 2012). Paleoecological studies can describe the context for which biodiversity persisted through time climate refugia. Third, the paleoecological approach is especially suited for long-lived organisms. For example, a tree species that may typically reach reproductive sizes only after 50 years and remain fertile for 300 years, will experience only 30 to 200 generations since colonizing a location after Holocene warming about 11,000 years ago. Thus, by summarizing community change through multiple generations and natural disturbance events, paleoecological studies can examine the resilience of ecosystems to disturbances in the past, showing how many ecosystems recover quickly while others may not (Willis et al., 2010).
Book Synopsis Wetland and Riparian Areas of the Intermountain West by : Mark C. McKinstry
Download or read book Wetland and Riparian Areas of the Intermountain West written by Mark C. McKinstry and published by University of Texas Press. This book was released on 2010-01-01 with total page 327 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wetlands and riparian areas between the Rocky Mountains and the Sierra Nevada are incredibly diverse and valuable habitats. More than 80 percent of the wildlife species in this intermountain region depend on these wetlands—which account for less than 2 percent of the land area—for their survival. At the same time, the wetlands also serve the water needs of ranchers and farmers, recreationists, vacation communities, and cities. It is no exaggeration to call water the "liquid gold" of the West, and the burgeoning human demands on this scarce resource make it imperative to understand and properly manage the wetlands and riverine areas of the Intermountain West. This book offers land managers, biologists, and research scientists a state-of-the-art survey of the ecology and management practices of wetland and riparian areas in the Intermountain West. Twelve articles examine such diverse issues as laws and regulations affecting these habitats, the unique physiographic features of the region, the importance of wetlands and riparian areas to fish, wildlife, and livestock, the ecological function of these areas, their value to humans, and the methods to evaluate these habitats. The authors also address the human impacts on the land from urban and suburban development, mining, grazing, energy extraction, recreation, water diversions, and timber harvesting and suggest ways to mitigate such impacts.
