Book Description
Amphibians are among the most threatened groups of animals on earth. In part due to their highly permeable skin, amphibians are highly sensitive to environmental changes and pollution and provide an early-warning system of deteriorating environmental conditions. The more we learn about the impact of environmental changes on amphibians, the better we as humans will be able to arrest their demise, and our own. Status of Conservation and Decline of Amphibians brings together the current knowledge on the status of the unique frogs of Australia, New Zealand, and the Pacific. Although geographically proximate, each region presents unique challenges and opportunities in amphibian research and conservation. This book contributes to an understanding of the current conservation status of the amphibians of each region, aims to stimulate research into halting amphibian declines, and provides a better foundation for making conservation decisions. It is an invaluable reference for environmental and governmental agencies, researchers, policy-makers involved with biodiversity conservation, and the interested public.

Book Description
Consisting of more than six thousand species, amphibians are more diverse than mammals and are found on every continent save Antarctica. Despite the abundance and diversity of these animals, many aspects of the biology of amphibians remain unstudied or misunderstood. The Ecology and Behavior of Amphibians aims to fill this gap in the literature on this remarkable taxon. It is a celebration of the diversity of amphibian life and the ecological and behavioral adaptations that have made it a successful component of terrestrial and aquatic ecosystems. Synthesizing seventy years of research on amphibian biology, Kentwood D. Wells addresses all major areas of inquiry, including phylogeny, classification, and morphology; aspects of physiological ecology such as water and temperature relations, respiration, metabolism, and energetics; movements and orientation; communication and social behavior; reproduction and parental care; ecology and behavior of amphibian larvae and ecological aspects of metamorphosis; ecological impact of predation on amphibian populations and antipredator defenses; and aspects of amphibian community ecology. With an eye towards modern concerns, The Ecology and Behavior of Amphibians concludes with a chapter devoted to amphibian conservation. An unprecedented scholarly contribution to amphibian biology, this book is eagerly anticipated among specialists.

Book Description
Herpetology has always been one of the most exciting disciplines of zoology. During the past few years the field has continued to grow, yet it has been plagued by scarcity of comprehensive, up-to-date textbooks containing the most important developments. This timely book fills that void. Through skillful synthesis, the author summarizes the diversity in the biology of living amphibians and reptiles and describes the breadth of current herpetological research. Topics covered include the evolution, classification, development, reproduction, population, and environmental issues surrounding the study of amphibians and reptiles. Designed as an advanced undergraduate textbook, Herpetology is a valuable resource for students, practitioners, and interested amateurs alike. - Provides an incisive survey and much needed update of the field - Emphasizes the biological diversity among amphibians and reptiles - Details the most recent research findings, citing ke

Book Description
In an age when advanced molecular and genetic tools allow studies in various systems, amphibian metamorphosis still offers perhaps the most accessible model for the study of postembryonic organogenesis and mechanisms of hormonal regulation during vertebrate development. Amphibian Metamorphosis: From Morphology to Molecular Biology integrates findings from the most recent research with earlier observations, providing molecular and mechanistic insights into the signal transduction pathways underlying tissue-specific transformations during metamorphosis. The author, renowned expert of anuran metamorphosis and Head of the Unit of Molecular Morphogenesis at NICHD/NIH, begins with an overview of metamorphosis in different classes of amphibians and various factors that influence this process. A review of earlier morphological, cellular, and biochemical changes focuses on organs and tissues that have been studied extensively at the molecular level, while discussion of the thyroid hormone signal transduction pathway emphasizes transcriptional regulation mechanisms by thyroid receptors. The book provides a summary and comparison of gene regulation programs induced by thyroid hormone in several organs that undergo distinct metamorphic transformations. Several chapters are devoted to functional and mechanistic implications of the molecular findings on the thyroid hormone response genes in tissue transformation. Special features of this book include: * An emphasis on integrating the morphological approach with molecularand cell biology * A historical perspective on the progression from discovery of the thyroid hormone to present-day research advances * Comparisons of amphibian and insect metamorphosis * Dozens of instructive photographs, several in full color Amphibian Metamorphosis: From Morphology to Molecular Biology is a unique and invaluable resource for professionals and aspiring professionals in develop-mental biology, molecular biology, cell biology, evolutionary biology, and endocrinology.

Book Description
2009 Outstanding Academic Title, ChoiceHonorable Mention, Biological and Life Sciences, 2009 PROSE Awards, Professional and Scholarly Publishing division of the Association of American Publishers For nearly 100 million years, amphibians and their ancestors dominated the terrestrial and shallow water environments of the earth. Archaic animals with an amphibious way of life gave rise not only to modern frogs, salamanders, and caecilians but also to the ancestors of reptiles, birds, and mammals. In this landmark publication, one of the leading paleontologists of our time explores a pivotal moment in vertebrate evolution, the rise of amphibians. Synthesizing findings from the rich and highly diverse fossil record of amphibians, Robert Carroll traces their origin back 365 million years, when particular species of fish traveled down an evolutionary pathway of fin modification that gave rise to legs. This period of dramatic radiation was followed by a cataclysmic extinction 250 million years ago. After a long gap, modern amphibian groups gradually emerged. Now the number of amphibian species and individuals throughout the tropical and temperate regions of the earth exceeds that of mammals. The Rise of Amphibians is documented with more than two hundred illustrations of fossil amphibians and sixteen exquisite color plates depicting amphibians in their natural habitats throughout their long existence. The most comprehensive examination of amphibian evolution ever produced, The Rise of Amphibians is an essential resource for paleontologists, herpetologists, geologists, and evolutionary biologists.
