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
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
Barking frogs, giant cane toads, six-foot-long Chinese salamanders, and tiny dwarf sirens-all these and many more are amphibians who live in the two worlds of water and land. The Amphibian Class describes the origins and ways of life of the three main kinds of amphibians, with a look at many weird and wonderful species. It covers the amphibian life cycle from tadpole to tree frog, introduces the strange and seldom-seen creatures called caecilians, and even answers the age-old question: What's the difference between a frog and a toad? The Amphibian Class also explains why many scientists fear that these ancient animals are in serious trouble today and looks at some of the things being done to help them survive into the future.

Book Description
This is a book for all readers who want to learn about amphibians, the animal group that includes frogs, toads, salamanders, and caecilians. It draws on many years of classroom teaching, laboratory experience, and field observation by the authors. Robert Stebbins and Nathan Cohen lead readers on a fascinating odyssey as they explore some of nature's most interesting creatures, interspersing their own observations throughout the book. A Natural History of Amphibians can serve as a textbook for students and independent learners, as an overview of the field for professional scientists and land managers, and as an engaging introduction for general readers. The class Amphibia contains more than 4,500 known living species. New species are being discovered so rapidly that the number may grow to more than 5,000 during our lifetimes. However, their numbers are being rapidly decimated around the globe, largely due to the encroachment of humans on amphibian habitats and from growing human-caused environmental pollution, discussed at length in the final chapter. The authors focus our attention on the "natural history" of amphibians worldwide and emphasize their interactions with their environments over time: where they live; how they reproduce; how they have been affected by evolutionary processes; what factors will determine their destinies over time. Through the experienced eyes of the authors, who are skilled observers, we come to see and understand the place of amphibians in the natural world around us.

Book Description
Around 370 million years ago, a distant relative of a modern lungfish began a most extraordinary adventure--emerging from the water and laying claim to the land. Over the next 70 million years, this tentative beachhead had developed into a worldwide colonization by ever-increasing varieties of four-limbed creatures known as tetrapods, the ancestors of all vertebrate life on land. This new edition of Jennifer A. Clack's groundbreaking book tells the complex story of their emergence and evolution. Beginning with their closest relatives, the lobe-fin fishes such as lungfishes and coelacanths, Clack defines what a tetrapod is, describes their anatomy, and explains how they are related to other vertebrates. She looks at the Devonian environment in which they evolved, describes the known and newly discovered species, and explores the order and timing of anatomical changes that occurred during the fish-to-tetrapod transition.

Book Description
"Evidence bases for conservation are becoming increasingly important to convince landowners and politicians of the need to take action in defence of species and habitats all around the world. A valuable feature of this book is its emphasis on collecting and analysing such essential information." Trevor Beebee, Phyllomedusa Amphibians are among the most globally endangered groups of vertebrates with more than one-third of species being assessed as declining or threatened. Often, amphibian declines can be attributed to a suite of interacting factors, many of which are human in origin, but further information is needed to elaborate the key causes and to discover ways of reversing declines. Robust surveys provide vital ecological and biological data on amphibian populations, and underpin the decisions made to protect species and reverse their declines. Ongoing monitoring informs land managers and decision makers about whether they are taking the right action. This book is designed to help you carry out amphibian surveying and monitoring so that the results of your surveys can be used effectively. Part 1 introduces amphibians: order Anura (frogs and toads); Caudata (newts and salamanders); and order Gymnophonia (caecilians). Part 2 is essential reading before you start surveying. It introduces the different types of survey and monitoring programmes and discusses survey aims and resources. It contains chapters on collecting and handling survey data; survey permissions and licencing; health and safety, and biosecurity; and handling amphibians. Part 3 discusses everything you need to know during your survey, and provides a detailed look at amphibian survey methods. Part 4 covers presenting and using your survey’s data to best effect. A useful resources section is also provided, with example survey forms and details of additional information resources that will optimize the impacts of your surveys. Key amphibian survey techniques are discussed with reference to published examples of successful surveys – so you’ll be able to choose what’s right for your situation. Tips on optimizing your survey effort and handling amphibians in the field are also included. Whether carrying out a student expedition project or seeking information to support the management of a protected area, this book contains essential advice from an amphibian ecologist who has encountered the same sorts of decisions you’ll face when planning your surveys.
