The small, terrestrial eastern red-backed salamander is abundant on many forest floors of northeastern North America. Dr. Robert Jaeger and many of his graduate students spent over 50 years studying this species in New York and Virginia, using ecological techniques in forests and behavioral experiments in laboratory chambers in an attempt to understand how this species interacts with other species in the forest and the components of its intra- and intersexual social behaviors.The competitive and social behaviors of this species are unusually complex for an amphibian. This species is highly aggressive towards other similar-size species where they cohabit in forests, often leading to very little geographic overlap between the species. The authors examine the fascinating behavioral traits of this species including social monogamy, mutual mate guarding, sexual coercion, inter-species communication, and conflict resolution.

This book has three primary themes: identification, natural history, and conservation. This is the first guide yet produced to the amphibians and reptiles of New York State, a large and heavily populated state that hosts a surprisingly diverse and interesting community of amphibians and reptiles. The book presents the results of the New York State Amphibian and Reptile Atlas for the first time (a compilation of ~60,000 distributional records collected 1990-1999); thus, the volume is a repository for detailed distributional data on the 69 species native to the state. The book presents in-depth species accounts based on the six authors' decades of collective experience as teachers, researchers and conservationists. Supporting chapters focus on the biology of amphibians and reptiles, New York's environment, finding and studying these creatures, and the rich folklore of New York State as it pertains to amphibians and reptiles, particularly rattlesnakes. A heavy emphasis on conservation biology of amphibians and reptiles sets the book apart from any comparable volume yet produced in the United States. To this end, chapters on threats, legal protections, habitat conservation guidelines, and conservation case studies are presented. An expanded color insert presents striking photographs contributed by over 30 photographers. The book is intended for use by natural history buffs generally interested in the vertebrate animals of New York and adjoining regions (Pennsylvania, Connecticut, New Jersey, Massachusetts, Vermont, Quebec and Ontario), students in the many herpetology, vertebrate biology, and natural history courses offered at colleges and field stations in the northeast, public and college libraries, and natural resource professionals interested in learning more about approaches to conserving reptiles and amphibians.

Archie Carr, one of the greatest biologists of the twentieth century, played a leading part in finding a new and critical role for natural history and systematics in a post-1950s world dominated by the glamorous science of molecular biology. With the rise of molecular biology came a growing popular awareness of species extinction. Carr championed endangered sea turtles, and his work reflects major shifts in the study of ecology and evolution. A gifted nature writer, his books on the natural history of sea turtles and their habitats in Florida, the Caribbean, and Africa entertained and educated a wide audience. Carr's conservation ethic grew from his field work as well as his friendships with the fishermen who supplied him with many of the stories he retold so engagingly. With Archie Carr as the focus, The Man Who Saved Sea Turtles explores the evolution of the naturalist tradition, biology, and conservation during the twentieth century.

Anyone can look at a snake and see a creature unique unto itself, a reptile with a set of zoological and biological traits that are entirely its own. Just looking at this distinct animal raises many scientific questions. With regard to evolution, how did such an animal come to be? How does a snake move, and how do its sense organs differ from that of other reptiles? How does it eat, and how does it reproduce? Essentially, how does a snake "work"? In How Snakes Work: The Structure, Function and Behavior of the World's Snakes, leading zoologist Harvey B. Lillywhite has written the definitive scientific guide to the functional biology of snakes. Written for both herpetologists and a more general audience with an interest in the field, How Snakes Work features nearly two hundred color images of various species of snakes, used to provide visual examples of biological features explained in the text.Chapter topics include the evolutionary history of the snake, feeding, locomotion, the structure and function of skin, circulation and respiration, sense organs, sound production, and reproduction. Containing all the latest research and advances in our biological knowledge of the snake, How Snakes Work is an indispensable asset to professional zoologists and enthusiasts alike.

This book describes how the various alien reptiles and amphibians now living in the wild throughout the world were first introduced, how they subsequently became naturalized, their present distribution and status in those countries to which they were introduced, and their ecological and socio-economic impact (if any) on the native biota and local economies. Many species have had a more or less neutral impact, being neither beneficial nor harmful. However, several have had a positive ecological or socio-economic impact, while some such as the cane toad, have had an extremely destructive effect.The criteria for inclusion of a species are that it should have been imported from its natural range to a new country by human agency (either accidentally or deliberately) and that it should currently be established in the wild in self-maintaining and self-perpetuating populations unsupported by, and independent of, mankind.

Amphibians are the extant descendants of the first vertebrate class to successfully colonize terrestrial environments; hence they occupy a unique position between fish and reptiles. Amphibian skin provides essentially no resistance to evaporative water loss, and consequently daily water turnover rates are an order of magnitude greater than in other terrestrial vertebrate groups. This has led to a suite of physiological, morphological and behavioural adaptations that have allowed a successful terrestrial existence in spite of this apparently spendthrift water retention strategy. Ecological and Environmental Physiology of Amphibians provides a synthesis of current research on the comparative physiology of amphibians with a particular emphasis on water balance. It adopts a strong environmental perspective and includes a wealth of information on ecology, phylogeny and development. As with other books in the Ecological and Environmental Physiology Series, the emphasis in this book is on the unique physiological characteristics of the amphibians, although the latest experimental techniques and future research directions are also considered. This accessible text is suitable for both graduate students and researchers in the fields of amphibian comparative physiology and physiological ecology, including specialist courses in amphibian ecology. It will also be of value and use to the many professional herpetologists requiring a concise overview of the topic.

For millions of years reptiles have walked, crawled, and slithered over the face of our Earth. From the mighty dinosaurs who dominated the land, the pterosaurs who took to the air, and the marine adapted ichthyosaurs, to the living reptiles today such as the lizards, snakes, crocodiles, and turtles, plus the single species of tuatara in New Zealand, reptiles have come in all shapes and sizes. In this Very Short Introduction Tom Kemp discusses the adaptations reptiles made to first leave the sea and colonise the land in dry conditions, such as their waterproof skin, their ability to expel almost dry waste products, their efficient use of external heat for maintaining their body temperature, and the amniotic egg that is laid and develops on dry land. Considering the different living groups of reptiles today, Kemp then describes how their respective bodies are adapted for their different ways of life, from snake feeding patterns to the way crocodiles breathe. Finally, Kemp assesses the threat of extinction to reptile species due to over-exploitation, habitat destruction, and climate change, and considers what can be done.ABOUT THE SERIES: The Very Short Introductions series from Oxford University Press contains hundreds of titles in almost every subject area.

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.

In essays that survey the burgeoning field of tropical herpetology, former students and associates pay tribute to Jay Savage's four decades of mentoring. The result is a book unlike any other available in tropical herpetology. Covering a wide array of subjects, this is the first book in more than two decades to broadly review research on tropical amphibians and reptiles. A tribute to Savage and an invaluable addition to herpetological literature, it will be cited for years to come.

Through its emphasis on recent research, its many summary tables, and its bibliography of more than 4,000 entries, this first modern, synthetic treatment of comparative amphibian environmental physiology emerges as the definitive reference for the field. Forty internationally respected experts review the primary data, examine current research trends, and identify productive avenues for future research.

The third of a planned group of volumes dealing with reptilian nervous systems, Sensorimotor Integration focuses chiefly on visual and sensorimotor aspects of reptilian neurobiology. Chapters examine data for numerous species, drawing together the most current work and thinking on each topic and emphasizing results from recent studies. "This volume would be a valuable addition to any comparative anatomist's bookshelf, and one that should be of great interest to comparative neurobiologists and neuroanatomists alike."--Katherine V. Fite, Quarterly Review of Biology

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 declines in amphibian populations worldwide and the suitability of amphibians for use in answering research questions in disciplines as diverse as molecular systematics, animal behaviour and evolutionary biology have focused enormous attention on tadpoles. In this reference, experts on tadpole biology relate what is known about tadpoles and what one might learn from them in the future. The book provides summaries of tadpole morphology, development, behaviour, ecology and environmental physiology; explores the evolutionary consequences of the tadpole stage; synthesizes available information on their biodiversity; and presents a standardized terminology and a literature review of tadpole biology.
