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.

Available in PDF, EPUB and Kindle. Book excerpt: Forest Spiders of South East Asia offers the first comprehensive systematic account of all sac and ground spiders of South East Asia, which together constitute an estimated 12% of all spiders in the region. All ten subfamilies, 57 genera and numerous species of the region are defined, described, and illustrated. One new subfamily and a large number of new genera and species are described and named. Several hundreds additional, described and new, species are referred to. Distribution of all species covered in this volume is shown in 50 maps. More than a thousand line drawings and 16 colour photographs are used to illustrate the descriptions of the species, of which the great majority has never been illustrated before. The book provides a modern revision of all sac and ground spiders with clear illustrated diagnosis and descriptions of all known members of this group and many new species and genera. Identification of all 47 families occurring in the region is illustrated in beautiful and detailed drawings.

Download or read book Invasive Species in the Pacific Northwest written by P. Dee Boersma and published by Ewha Womans University Press. This book was released on 2006 with total page 316 pages. Available in PDF, EPUB and Kindle. Book excerpt: The U.S. government defines invasive species as "an alien species whose introduction does or is likely to cause economic or environmental harm or harm to human health." Invasive Species in the Pacific Northwest describes these species, how they got here, and the effects of their invasions on the region's environment. Each of 108 invasive species of fish, plants, invertebrates, mammals, and birds -- including earthworms, domestic cats and pigs, blackberries, European fruit flies, Japanese eelgrass, Mediterranean mussels, rats, and terrestrial mollusks -- is described in a 2-page spread that includes a full-color photograph of the species, a map showing the species' presence in the region, plus: -- Impact on communities and native species -- Control methods and management -- Life histories and species overview -- History of invasiveness Included are suggestions to help reduce the spread of invasive species; habitat preferences of Pacific Northwest invasive species; the World Conservation Union (ICUN) list of the world's 100 most invasive alien species; and a questionnaire designed to evaluate ecological impact and invasive potential. Invasive species have been recognized as an environmental issue since Charles Darwin's voyage on the H.M.S. Beagle. Editors P. D. Boersma, S. E. Reichard, and A. N. Van Buren explore the intentional and accidental introductions of invasive species. Whether these species were deliberately brought to the Northwest for agricultural, horticultural, aquacultural, or hunting and fishing purposes, or accidentally introduced as stowaways and contaminants, knowledge about them is integral to the protection of our environment.

This book was released on 2019-01-17 with total page 442 pages. Available in PDF, EPUB and Kindle. Book excerpt: Kin Recognition in Protists and Other Microbes is the first volume dedicated entirely to the genetics, evolution and behavior of cells capable of discriminating and recognizing taxa (other species), clones (other cell lines) and kin (as per gradual genetic proximity). It covers the advent of microbial models in the field of kin recognition; the polymorphisms of green-beard genes in social amebas, yeast and soil bacteria; the potential that unicells have to learn phenotypic cues for recognition; the role of clonality and kinship in pathogenicity (dysentery, malaria, sleeping sickness and Chagas); the social and spatial structure of microbes and their biogeography; and the relevance of unicells’ cooperation, sociality and cheating for our understanding of the origins of multicellularity. Offering over 200 figures and diagrams, this work will appeal to a broad audience, including researchers in academia, postdoctoral fellows, graduate students and research undergraduates. Science writers and college educators will also find it informative and practical for teaching.
Download or read book Carrion Ecology and Management written by Pedro P. Olea and published by Springer. This book was released on 2019-07-22 with total page 284 pages. Available in PDF, EPUB and Kindle. Book excerpt: Carrion, or dead animal matter, is an inherent component of aquatic and terrestrial ecosystems worldwide, and is exploited by a wide diversity of organisms from different trophic levels, including microbes, arthropods and vertebrates. Further, carrion consumption by scavengers, i.e. scavenging, supports key ecosystem functions and services such as recycling nutrients and energy, disposing of carcasses and regulating disease spread. Yet, unlike dead plant matter, dead animal decomposition has received little attention in the fields of ecology, wildlife conservation and environmental management, and as a result the management of carrion for maintaining biodiversity and functional ecosystems has been limited. This book addresses the main ecological patterns and processes relating to the generation and consumption of carrion both in terrestrial and aquatic ecosystems. It also discusses a number of conservation concerns and associated management issues, particularly regarding the increasing role of human-mediated carrion in ecosystems. Lastly, the book outlines future research lines in carrion ecology and management, and identifies the major challenges for scavengers and scavenging processes in the Anthropocene.
Download or read book The Goblin Spider Genus Ischnothyreus Araneae Oonopidae in the New World written by Norman I. Platnick and published by . This book was released on 2012 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although originally described from St. Vincent in the Lesser Antilles, the goblin spider genus Ischnothyreus Simon appears to be an Old World taxon that is represented in the New World only by two presumably introduced, pantropical, synanthropic species: I. peltifer (Simon) and I. velox Jackson. Two specific names based on New World specimens (I. barrowsi Chamberlin and Ivie from Florida, and I. indressus Chickering from the Lesser Antilles) are placed as junior synonyms of I. velox, which is newly recorded from Mexico, Panama, Jamaica, Hispaniola, Venezuela, Brazil, Madagascar, the Philippines, the Marshall Islands, Hawaii, the Marquesas Islands, and New Caledonia. A third species, I. browni Chickering, that is supposedly from Costa Rica was apparently based on mislabeled specimens that are actually from the Philippines. The type specimens of I. browni resemble those of the Seychelle species Ischnothyrella jivani (Benoit) in that the dorsal abdominal scutum of males is extremely weak and that of females is either greatly reduced or entirely lost. Both species nevertheless share the synapomorphies of Ischnothyreus, and the generic name Ischnothyrella Saaristo is therefore placed as a junior synonym of Ischnothyreus.

Download or read book The Theory of Evolution written by Samuel M. Scheiner and published by University of Chicago Press. This book was released on 2020-04-03 with total page 455 pages. Available in PDF, EPUB and Kindle. Book excerpt: Darwin’s nineteenth-century writings laid the foundations for modern studies of evolution, and theoretical developments in the mid-twentieth century fostered the Modern Synthesis. Since that time, a great deal of new biological knowledge has been generated, including details of the genetic code, lateral gene transfer, and developmental constraints. Our improved understanding of these and many other phenomena have been working their way into evolutionary theory, changing it and improving its correspondence with evolution in nature. And while the study of evolution is thriving both as a basic science to understand the world and in its applications in agriculture, medicine, and public health, the broad scope of evolution—operating across genes, whole organisms, clades, and ecosystems—presents a significant challenge for researchers seeking to integrate abundant new data and content into a general theory of evolution. This book gives us that framework and synthesis for the twenty-first century. The Theory of Evolution presents a series of chapters by experts seeking this integration by addressing the current state of affairs across numerous fields within evolutionary biology, ranging from biogeography to multilevel selection, speciation, and macroevolutionary theory. By presenting current syntheses of evolution’s theoretical foundations and their growth in light of new datasets and analyses, this collection will enhance future research and understanding.
