Download or read book Amphibian Conservation written by Rebecca K. Smith and published by Pelagic Publishing Ltd. This book was released on 2014-05-16 with total page 273 pages. Available in PDF, EPUB and Kindle. Book excerpt: Amphibian Conservation is the fourth in the series of Synopses of Conservation Evidence, linked to the online resource www.ConservationEvidence.com. This synopsis is part of the Conservation Evidence project and provides a useful resource for conservationists. It forms part of a series designed to promote a more evidence-based approach to biodiversity conservation. Others in the series include bee, bird, farmland and bat conservation and many others are in preparation. Approximately 32% of the 7,164+ amphibian species are currently threatened with extinction and at least 43% of species are declining. Despite this, until recently amphibians and their conservation had received little attention. Although work is now being carried out to conserve many species, often it is not adequately documented. This book brings together and summarises the available scientific evidence and experience relevant to the practical conservation of amphibians. The authors consulted an international group of amphibian experts and conservationists to produce a thorough summary of what is known, or not known, about the effectiveness of amphibian conservation actions across the world. "The book is packed with literature summaries and citations; a veritable information goldmine for graduate students and researchers. It also admirably provides decision makers with a well-researched resource of proven interventions that can be employed to stem/reverse the decline of amphibian populations." -John G Palis, Bulletin of the Chicago Herpetological Society

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.

Download or read book Amphibian Evolution written by Rainer R. Schoch and published by John Wiley & Sons. This book was released on 2014-03-19 with total page 564 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book focuses on the first vertebrates to conquer land and their long journey to become fully independent from the water. It traces the origin of tetrapod features and tries to explain how and why they transformed into organs that permit life on land. Although the major frame of the topic lies in the past 370 million years and necessarily deals with many fossils, it is far from restricted to paleontology. The aim is to achieve a comprehensive picture of amphibian evolution. It focuses on major questions in current paleobiology: how diverse were the early tetrapods? In which environments did they live, and how did they come to be preserved? What do we know about the soft body of extinct amphibians, and what does that tell us about the evolution of crucial organs during the transition to land? How did early amphibians develop and grow, and which were the major factors of their evolution? The Topics in Paleobiology Series is published in collaboration with the Palaeontological Association, and is edited by Professor Mike Benton, University of Bristol. Books in the series provide a summary of the current state of knowledge, a trusted route into the primary literature, and will act as pointers for future directions for research. As well as volumes on individual groups, the series will also deal with topics that have a cross-cutting relevance, such as the evolution of significant ecosystems, particular key times and events in the history of life, climate change, and the application of a new techniques such as molecular palaeontology. The books are written by leading international experts and will be pitched at a level suitable for advanced undergraduates, postgraduates, and researchers in both the paleontological and biological sciences.

Download or read book Ecotoxicology Essentials written by Donald W. Sparling and published by Academic Press. This book was released on 2016-04-18 with total page 502 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ecotoxicology Essentials: Environmental Contaminants and Their Biological Effects on Animals and Plants provides a fundamental understanding of this area for students and professionals in ecotoxicology, ecology, conservation, chemistry, public health, wildlife management, fisheries, and many other disciplines. Although new chemicals and potential problems are developed every year, a basic education is essential to address these new challenges, and this work gives such training. Written with the regulatory framework in mind, the material guides readers on modelling, how to conduct assessments, and human and wildlife risk, focusing on effects on animals rather than transport of chemicals. Simple discussions of chemistry are complemented by coverage on the behavior of the animal, dynamics of the ecosystem, real-life situations like drought, and predators in the system – i.e., the natural system versus the lab setting. The book's first section contains chapters on the principles of contaminant toxicology including a brief history of the science of ecotoxicology, basic principles of the science, testing methods, and ways of determining if animals have been exposed to either acute or chronic concentrations of contaminants. The second section deals with the primary classes of contaminants including their chemical characteristics, sources, uses, and effects on organisms. The third section focuses on more complex issues such as the regulation of pollution, population and community effects, risk assessment and modelling. - Uses examples from both aquatic and terrestrial environments and species - Includes a Terms to Know section and a list of study questions in each chapter, fostering a greater understanding of the issues - Focuses on the effects of contaminants on wildlife while providing enough chemistry to allow a detailed understanding of the various contaminant groups - Emphasizes natural examples and 'real' species, rather than laboratory studies on only a handful of organisms - Features case histories, detailing actual events that include aspects of how the contamination occurred and its effects on wildlife - Provides material from a wide variety of international sources

This book was released on 2019-06-30 with total page 671 pages. Available in PDF, EPUB and Kindle. Book excerpt: The preeminent naturalists Albert Hazen Wright and Anna Allen Wright spent years assembling the wealth of material on frogs and toads appearing in this widely used handbook, the third edition of which was originally published in 1949. With abundant black-and-white photographs, colorful descriptions, journal notes from the field, and excerpts from the literature, their personalized natural history emphasizes amphibians observed in the wild. In a foreword to the 1995 paperback edition, Roy McDiarmid, a foremost specialist on frogs and toads, brings the book into historical perspective and supplies information to bring it up to date. Accounts of more than 100 species and subspecies cover such topics as common and scientific names, range, habitat, size, and general appearance, as well as color, structure, voice, and breeding. Separate keys are given for secondary sexual characteristics, eggs, tadpoles, families, and species. Generous quotations from the Wrights' field journals give the reader a sense of the problems and satisfactions of their work.

Download or read book Feline Clinical Parasitology written by Dwight D. Bowman and published by John Wiley & Sons. This book was released on 2008-02-08 with total page 482 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although there are books available dealing with canine parasitology, there is at present no book detailing parasites that offers clinical information specific to felines. Cats differ significantly from dogs in their parasitic infections and infestations. Although dogs and cats do share a few parasites, the vast majority of the parasites of these pets are specific to either cats or dogs, not to both. This must-have reference offers an in-depth examination of feline parasites. Topics covered include parasite identification, history, geographic distribution, pathogeneisis, epidemiology, zoonosis, diagnosis, treatment, control, and prevention. Because of the immense worldwide popularity of cats and due to the amount of travel undertaken by cats and their owners, the authors have produced a book that is international in scope. Consequently, this exhaustive reference has strong appeal to practitioners and veterinary parasitologists in North America and around the world.
