Book Synopsis A Handbook of Global Freshwater Invasive Species by : Robert A. Francis
Download or read book A Handbook of Global Freshwater Invasive Species written by Robert A. Francis and published by Routledge. This book was released on 2012-03-12 with total page 918 pages. Available in PDF, EPUB and Kindle. Book excerpt: Invasive non-native species are a major threat to global biodiversity. Often introduced accidentally through international travel or trade, they invade and colonize new habitats, often with devastating consequences for the local flora and fauna. Their environmental impacts can range from damage to resource production (e.g. agriculture and forestry) and infrastructure (e.g. buildings, road and water supply), to human health. They consequently can have major economic impacts. It is a priority to prevent their introduction and spread, as well as to control them. Freshwater ecosystems are particularly at risk from invasions and are landscape corridors that facilitate the spread of invasives. This book reviews the current state of knowledge of the most notable global invasive freshwater species or groups, based on their severity of economic impact, geographic distribution outside of their native range, extent of research, and recognition of the ecological severity of the impact of the species by the IUCN. As well as some of the very well-known species, the book also covers some invasives that are emerging as serious threats. Examples covered include a range of aquatic and riparian plants, insects, molluscs, crustacea, fish, amphibians, reptiles and mammals, as well as some major pathogens of aquatic organisms. The book also includes overview chapters synthesizing the ecological impact of invasive species in fresh water and summarizing practical implications for the management of rivers and other freshwater habitats.

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 Dispersal Ecology and Evolution by : Jean Clobert
Download or read book Dispersal Ecology and Evolution written by Jean Clobert and published by OUP Oxford. This book was released on 2012-09-27 with total page 496 pages. Available in PDF, EPUB and Kindle. Book excerpt: Now that so many ecosystems face rapid and major environmental change, the ability of species to respond to these changes by dispersing or moving between different patches of habitat can be crucial to ensuring their survival. Understanding dispersal has become key to understanding how populations may persist. Dispersal Ecology and Evolution provides a timely and wide-ranging overview of the fast expanding field of dispersal ecology, incorporating the very latest research. The causes, mechanisms, and consequences of dispersal at the individual, population, species, and community levels are considered. Perspectives and insights are offered from the fields of evolution, behavioural ecology, conservation biology, and genetics. Throughout the book theoretical approaches are combined with empirical data, and care has been taken to include examples from as wide a range of species as possible - both plant and animal.
Book Synopsis The Biology and Evolution of Trematodes by : K. V. Galaktionov
Download or read book The Biology and Evolution of Trematodes written by K. V. Galaktionov and published by Springer Science & Business Media. This book was released on 2013-12-01 with total page 605 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book by K. V. Galaktionov and A. A. Dobrovolskij maintains the tra- tion of monographs devoted to detailed coverage of digenetic tr matodes in the tradition of B. Dawes (1946) and T. A. Ginetsinskaya (1968). In this - spect, the book is traditional in both its form and content. In the beginning (Chapter 1), the authors provide a consistent analysis of the morphological features of all life cycle stages. Importantly, they present a detailed char- terization of sporocysts and rediae whose morphological-functional orga- zation has never been comprehensively described in modern literature. The authors not only list morphological characteristics, but also analyze the functional significance of different morphological structures and hypothesize about their evolution. Special attention is given to specific features of m- phogenesis in all stages of the trematode life cycle. On this basis, the authors provide several original suggestions about the possible origins of morp- logical evolution of the parthenogenetic (asexual) and the hermaphroditic generations. This is followed by a detailed consideration of the various m- phological-biological adaptations that ensure the successful completion of the complex life cycles of these parasites (Chapter 2). Life cycles inherent in different trematodes are subject to a special analysis (Chapter 3). The authors distinguish several basic types of life cycles and suggest an original interpretation of their evolutionary origin. Chapter 4 features the analysis of structure and the dynamics of trematode populations and is unusual for a monograph of this type.
Book Synopsis Measuring and Monitoring Biological Diversity by : Ronald Heyer
Download or read book Measuring and Monitoring Biological Diversity written by Ronald Heyer and published by Smithsonian Institution. This book was released on 2014-12-16 with total page 537 pages. Available in PDF, EPUB and Kindle. Book excerpt: Measuring and Monitoring Biological Diversity is the first book to provide comprehensive coverage of standard methods for biodiversity sampling of amphibians, with information on analyzing and using data that will interest biologists in general. In this manual, nearly fifty herpetologists recommend ten standard sampling procedures for measuring and monitoring amphibian and many other populations. The contributors discuss each procedure, along with the circumstances for its appropriate use. In addition, they provide a detailed protocol for each procedure's implementation, a list of necessary equipment and personnel, and suggestions for analyzing the data. The data obtained using these standard methods are comparable across sites and through time and, as a result, are extremely useful for making decisions about habitat protection, sustained use, and restoration—decisions that are particularly relevant for threatened amphibian populations.

Book Synopsis Occupancy Estimation and Modeling by : Darryl I. MacKenzie
Download or read book Occupancy Estimation and Modeling written by Darryl I. MacKenzie and published by Elsevier. This book was released on 2017-11-17 with total page 668 pages. Available in PDF, EPUB and Kindle. Book excerpt: Occupancy Estimation and Modeling: Inferring Patterns and Dynamics of Species Occurrence, Second Edition, provides a synthesis of model-based approaches for analyzing presence-absence data, allowing for imperfect detection. Beginning from the relatively simple case of estimating the proportion of area or sampling units occupied at the time of surveying, the authors describe a wide variety of extensions that have been developed since the early 2000s. This provides an improved insight about species and community ecology, including, detection heterogeneity; correlated detections; spatial autocorrelation; multiple states or classes of occupancy; changes in occupancy over time; species co-occurrence; community-level modeling, and more. Occupancy Estimation and Modeling: Inferring Patterns and Dynamics of Species Occurrence, Second Edition has been greatly expanded and detail is provided regarding the estimation methods and examples of their application are given. Important study design recommendations are also covered to give a well rounded view of modeling. - Provides authoritative insights into the latest in occupancy modeling - Examines the latest methods in analyzing detection/no detection data surveys - Addresses critical issues of imperfect detectability and its effects on species occurrence estimation - Discusses important study design considerations such as defining sample units, sample size determination and optimal effort allocation
Download or read book Amphibians of China written by Liang Fei and published by Springer. This book was released on 2016-02-04 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book describes each amphibian with its alternate name, its main characteristics, biological data, population status, and geographic distribution. Each entry is accompanied by plenty of figures and colored pictures of the amphibian and its geographic distribution map. These illustrate China's amphibian species diversity and the latest research findings. It is the most comprehensive summary of China's amphibians. The text and picture combination aids species identification and comparison, and is valuable for the in-depth study of their phylogeny. Its detailed, comprehensive and illustrative descriptions help to identify amphibian species, and have important academic significance for further surveys and research on amphibian numbers, animal protection and the development of protective measures as well as quarantine in customs. It provides important information for research units concerned with amphibians both in China, and the rest of the world, and also for animal protection and law enforcement agencies. Professor Liang Fei, was formerly the director of the department of the herpetological research at Chengdu Institute of Biology, the Chinese Academy of Sciences, Chengdu, China; Professor Changyuan Ye works at Chengdu Institute of Biology, the Chinese Academy of Sciences, Chengdu, China;
Download or read book Tadpoles written by Roy W. McDiarmid and published by University of Chicago Press. This book was released on 1999-11 with total page 476 pages. Available in PDF, EPUB and Kindle. Book excerpt: In our own juvenile stage, many of us received our wide-eyed introduction to the wonders of nature by watching the metamorphosis of swimming tadpoles into leaping frogs and toads. The recent alarming declines in amphibian populations worldwide and the suitability of amphibians for use in answering research questions in disciplines as diverse as molecular systematics, animal behavior, and evolutionary biology have focused enormous attention on tadpoles. Despite this popular and scientific interest, relatively little is known about these fascinating creatures. In this indispensable reference, leading experts on tadpole biology relate what we currently know about tadpoles and what we might learn from them in the future. Tadpoles provides detailed summaries of tadpole morphology, development, behavior, ecology, and environmental physiology; explores the evolutionary consequences of the tadpole stage; synthesizes available information on their biodiversity; and presents a standardized terminology and an exhaustive literature review of tadpole biology.

Book Synopsis Parasite Communities: Patterns and Processes by : Gerald W. Esch
Download or read book Parasite Communities: Patterns and Processes written by Gerald W. Esch and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 397 pages. Available in PDF, EPUB and Kindle. Book excerpt: We first discussed the possibility of organizing a symposium on helminth communities in June, 1986. At that time, we were engaged in writing a joint paper on potential structuring mechanisms in helminth communities; we disagreed on a number of issues. We felt the reason for such debate was because the discipline was in a great state of flux, with many new concepts and approaches being introduced with increasing frequency. After consider able discussion about the need, scope and the inevitable limitations of such a symposium, we decided that the time was ripe to bring other ecologists, engaged in similar research, face-to-face. There were many individuals from whom to choose; we selected those who were actively publishing on helminth communities or those who had expertise in areas which we felt were particularly appropriate. We compiled a list of potential participants, contacted them and received unanimous support to organize such a symposium. Our intent was to cover several broad areas, fully recognizing that breadth negates depth (at least with a publisher's limitation on the number of pages). We felt it important to consider patterns amongst different kinds of hosts because this is where we had disagreed among ourselves.
