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.

Book Description
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.

Book Description
This book appears at a time when molecular cytogenetics is positioned to make a significant impact upon evolutionary studies, enabling problems of chromosomal structure and change to be critically assessed. It is an up-to-date and comprehensive survey of the cytogenetics of a major class of animals, including all three amphibian orders, with chapters authored by international leaders in the field.Amphibian Cytogenetics and Evolution will be of interest to classical and molecular cytogeneticists, systematicists, evolutionary biologists, herpetologists, and anyone using amphibians in genetic research. Offers the only current and comprehensive survey of amphibian cytogenetics Gives authoritative and in-depth coverage of topics of present interest Reviews general cytogenetic topics Presents new insights into evolutionary changes in chromosome structure and amphibian phylogeny and relationships including: Phylogenetic analysis of chromosome data, Current techniques of cytogenetic analysis, Examination of all three amphibian orders

Book Description
Amphibians are the oldest tetrapod group and show an astonishing diversity in lifestyles, many of them being unique. However, globally, they are on a decline. Hence, their study is fundamental to understanding the evolution of diversity and conserving them. This book, authored by experts from around the world, summarizes the current knowledge on the evolutionary ecology of amphibians. The book treats biological concepts related to the evolution, ecology, physiology, immunology, behaviour, and morphology of amphibians in their different states. This book constitutes an actualized work indispensable for evolutionary ecologists and herpetologists.

Book Description
Very Short Introductions: Brilliant, Sharp, Inspiring From frogs, toads, newts, and salamanders, to the lesser-known caecilians, there are over 8,000 species of amphibians alive today. Characterised by their moist, naked skin and the tadpole phase of their lives, they are uniquely adapted to occupy the interphase habitat between freshwater and land. This Very Short Introduction explores amphibians' evolution, adaptations, and biology, from the first emergence of tetrapods onto land 370 million years ago, to how their permeable skin enables them to thrive in their habitat today. T. S. Kemp describes how different amphibians go about their lives, looking in particular at their complex courtship behaviour and their extraordinary means of providing care for their eggs and larvae. Finally, he considers amphibians' relationship to humans, and the ways in which they have been exploited as food, folk medicine, and pets, as well as used in many areas of scientific research. Today amphibians face a serious threat, with almost half of species judged to be at risk of extinction. As the causes include habitat destruction, pollution, and disease, mostly resulting from human activity, T. S. Kemp shows that the conservation of amphibians is very much in our hands. ABOUT THE SERIES: The Very Short Introductions series from Oxford University Press contains hundreds of titles in almost every subject area. These pocket-sized books are the perfect way to get ahead in a new subject quickly. Our expert authors combine facts, analysis, perspective, new ideas, and enthusiasm to make interesting and challenging topics highly readable.
