Book Synopsis Alien Reptiles and Amphibians by : Fred Kraus
Download or read book Alien Reptiles and Amphibians written by Fred Kraus and published by Springer Science & Business Media. This book was released on 2008-12-19 with total page 571 pages. Available in PDF, EPUB and Kindle. Book excerpt: Transportation of species to areas outside their native ranges has been a feature of human culture for millennia. During this time such activities have largely been viewed as beneficial or inconsequential. However, it has become increasingly clear that human-caused introductions of alien biota are an ecological disruption whose consequences rival those of better-known insults like chemical pollution, habitat loss, and climate change. Indeed, the irreversible nature of most alien-species int- ductions makes them less prone to correction than many other ecological problems. Current reshuffling of species ranges is so great that the present era has been referred to by some as the “Homogocene” in an effort to reflect the unique mag- tude of the changes being made. These alien interlopers often cause considerable ecological and economic d- age where introduced. Species extinctions, food-web disruptions, community alte- tions, ecosystem conversion, changes in nutrient cycling, fisheries collapse, watershed degradation, agricultural loss, building damage, and disease epidemics are among the destructive – and frequently unpredictable – ecological and economic effects that invasive alien species can inflict. The magnitude of these damages c- tinues to grow, with virtually all environments heavily used by humans now do- nated by alien species and many “natural” areas becoming increasingly prone to alien invasion as well. Attention to this problem has increased in the past decade or so, and efforts to prevent or limit further harm are gaining wider scientific and political acceptance.

Book Synopsis The Ecology, Exploitation and Conservation of River Turtles by : Don Moll
Download or read book The Ecology, Exploitation and Conservation of River Turtles written by Don Moll and published by Oxford University Press. This book was released on 2004-04-08 with total page 408 pages. Available in PDF, EPUB and Kindle. Book excerpt: The underlying theme of this book is that a widespread, taxonomically diverse group of animals, important both from ecological and human resource perspectives, remains poorly understood and in delcine, while receiving scant attention from the ecological and conservation community. This volume proposes a comprehensive overview of the world's river turtles' ecology, conservation, and management. It begins with a categorization of taxa which inhabit flowing water habitats followed by information on their evolutionary and physical diversity and biogeography. Within the framework of ecology, the authors discuss the composition of river turtle communities in different types of lotic habitats and regions, population dynamics, movements, reproductive characteristics and behavior, predators, and feeding relationships. In a conservation and management section, the authors identify and evaluate the nature and intensity of factors which threaten river turtle survival--almost all of which involve direct human exploitation or indirect effects of human induced habitat alteration and degradation. They then list and evaluate the various schemes which have been proposed or employed to halt declines and restore populations, and make recommendations for future management plans for specific species and regions. In closing, they state their viewpoint concerning future research directions and priorities, and an evaluation of future prospects for survival of the world's river turtle species.
Book Synopsis The Timetree of Life by : S. Blair Hedges
Download or read book The Timetree of Life written by S. Blair Hedges and published by OUP Oxford. This book was released on 2009-04-23 with total page 1237 pages. Available in PDF, EPUB and Kindle. Book excerpt: The evolutionary history of life includes two primary components: phylogeny and timescale. Phylogeny refers to the branching order (relationships) of species or other taxa within a group and is crucial for understanding the inheritance of traits and for erecting classifications. However, a timescale is equally important because it provides a way to compare phylogeny directly with the evolution of other organisms and with planetary history such as geology, climate, extraterrestrialimpacts, and other features.The Timetree of Life is the first reference book to synthesize the wealth of information relating to the temporal component of phylogenetic trees. In the past, biologists have relied exclusively upon the fossil record to infer an evolutionary timescale. However, recent revolutionary advances in molecular biology have made it possible to not only estimate the relationships of many groups of organisms, but also to estimate their times of divergence with molecular clocks. The routineestimation and utilization of these so-called 'time-trees' could add exciting new dimensions to biology including enhanced opportunities to integrate large molecular data sets with fossil and biogeographic evidence (and thereby foster greater communication between molecular and traditional systematists). Theycould help estimate not only ancestral character states but also evolutionary rates in numerous categories of organismal phenotype; establish more reliable associations between causal historical processes and biological outcomes; develop a universally standardized scheme for biological classifications; and generally promote novel avenues of thought in many arenas of comparative evolutionary biology.This authoritative reference work brings together, for the first time, experts on all major groups of organisms to assemble a timetree of life. The result is a comprehensive resource on evolutionary history which will be an indispensable reference for scientists, educators, and students in the life sciences, earth sciences, and molecular biology. For each major group of organism, a representative is illustrated and a timetree of families and higher taxonomic groups is shown. Basic aspects ofthe evolutionary history of the group, the fossil record, and competing hypotheses of relationships are discussed. Details of the divergence times are presented for each node in the timetree, and primary literature references are included. The book is complemented by an online database(www.timetree.net) which allows researchers to both deposit and retrieve data.

Book Synopsis The Origin and Early Evolutionary History of Snakes by : David J. Gower
Download or read book The Origin and Early Evolutionary History of Snakes written by David J. Gower and published by Cambridge University Press. This book was released on 2022-08-11 with total page 489 pages. Available in PDF, EPUB and Kindle. Book excerpt: Snakes comprise nearly 4,000 extant species found on all major continents except Antarctica. Morphologically and ecologically diverse, they include burrowing, arboreal, and marine forms, feeding on prey ranging from insects to large mammals. Snakes are strikingly different from their closest lizard relatives, and their origins and early diversification have long challenged and enthused evolutionary biologists. The origin and early evolution of snakes is a broad, interdisciplinary topic for which experts in palaeontology, ecology, physiology, embryology, phylogenetics, and molecular biology have made important contributions. The last 25 years has seen a surge of interest, resulting partly from new fossil material, but also from new techniques in molecular and systematic biology. This volume summarises and discusses the state of our knowledge, approaches, data, and ongoing debates. It provides reviews, syntheses, new data and perspectives on a wide range of topics relevant to students and researchers in evolutionary biology, neontology, and palaeontology.

Book Synopsis Guide to the Reptiles and Amphibians of the Savannah River Site by : J. Whitfield Gibbons
Download or read book Guide to the Reptiles and Amphibians of the Savannah River Site written by J. Whitfield Gibbons and published by University of Georgia Press. This book was released on 2010-01-01 with total page 146 pages. Available in PDF, EPUB and Kindle. Book excerpt: Host to more than one hundred species of reptiles and amphibians, the Savannah River Site, a 780-square-kilometer tract in South Carolina, is one of the most intensely studied areas of herpetological ecology in the world. This guide is a summary of basic information on the site’s richly varied herpetofauna, from their taxonomy and distribution to their behavior and habitats. Keys to identify the adult and larval forms of the site’s known species comprise the core of the guide. These keys are supplemented by maps, graphs, and illustrations as well as by information on habitats; population characteristics and distribution; behavior related to movement, feeding, and reproduction; morphology; and techniques for collecting specimens. The guide also includes information about special identification and study problems involving unresolved sighting reports; subspeciation; and venomous, edible, endangered, and introduced species. Finally, a bibliography gives not only the sources referred to in the guide but virtually all studies and reports based on herpetological research conducted at the Savannah River Site. The site-related publications are listed by author but can also be found through an index to the subjects they cover. Guide to the Reptiles and Amphibians of the Savannah River Site is a valuable one-volume introduction to the existing information on herpetofauna at the site and to the countless research opportunities the site still presents. Because it is clearly written and designed and lists most of the reptiles and amphibians found in Georgia and South Carolina, the guide is also useful to wildlife observers--professional and amateur--in those states.
Book Synopsis Amphibians and Reptiles of Texas by : James Ray Dixon
Download or read book Amphibians and Reptiles of Texas written by James Ray Dixon and published by Texas A&M University Press. This book was released on 2000 with total page 442 pages. Available in PDF, EPUB and Kindle. Book excerpt: IN THIS REVISED edition of Amphibians and Reptiles of Texas, James R. Dixon adds to and updates the extensive information given in the first edition. A new section on conservation issues highlights some of the problems facing the continued survival of amphibians and reptiles, particularly commercial collecting and habitat destruction. Taxonomic changes have been made to reflect the latest scientific information, and the extensive listing of the literature on Texas amphibians and reptiles has been updated through April, 1999. Going back to the writings of French botanist Jean Louis Berlandier, who encountered Texas herpetofauna during his travels from 1828 to 1834, this list covers more than 150 years of inquiry into the state's species and is also testimony to the distinguished careers of such herpetologists as Hobart M. Smith and, more recently, Chris McAllister. Another prominent feature of this book is the more than 150 distribution maps, which show by county the updated distribution records for all native Texas amphibians and reptiles, based on more than 13,000 county records and more than 110,000 individual localities. Professional and amateur herpetologists as well as environmentalists, wildlife specialists, campers, and hikers will find the dichotomous keys useful for identifying species at hand. This aid to identification is supported by a glossary, drawings and photographs, and complete scientific and common names.
