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.

Charles Ernest Overton's 1901 monograph Studien aber die Narkose has become a scientific classic in a number of different fields. This book represents the first English translation, and in fact the first translation into any other language, of the original German work. In addition to· the edited translation, this volume contains introductory chapters by Keith Miller, Peter Winter and Leonard Firestone and myself. As editor, I have attempted above all else to ensure that the translation faithfully represents Overton's ideas and data, while making the material readily understandable to the modem scientific reader. This has frequently required that extremely long sentences, common in turn-of the-century German but considered cumbersome today, be simplified into two or even three sentences. In addition, I have paid particular attention to the correct translation of scientific terms, and I accept complete responsibility for any inaccuracies in this area. Overton's original contents list included headings and subheadings, but only a fraction of these appear in the original text. For the sake of clarity they have all been included in the body of the translated work. Also included is an index containing all chemicals mentioned in the book, along with their Chemical Abstracts System Registry Numbers for un ambiguous identification, a complete list of Overton's publications (Appendix B), and a list of all biographical articles about Overton and articles dealing specifically with analyses of his data (Appendix C).

Lost Frogs and Hot Snakes reveals the thrills and travails that herpetologists experience when working with amphibians and reptiles in the wild. With essays from fifty field biologists, this volume, edited by Martha L. Crump, presents a multifaceted yet intimate look at life in pursuit of knowledge about the natural world. From the beaches of Peru to the mountains of China, the stories in this collection place readers in the boots of field biologists as they watch, count, experiment, and survey. Some recall mishaps and misadventures—contending with leeches, dangling off a precipice while in a truck. Others tell of once-in-a-lifetime encounters—discovering a new frog species, spotting a rare snake. Together, these stories offer an understanding of what field biology is, what field biologists do, and how they go about doing it. Written with candor, warmth, and a dash of humor, the stories in Lost Frogs and Hot Snakes will encourage readers to appreciate the value of engaging with nature and of the amphibians and reptiles so critical to the vitality of our planet.

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.

"Frogs and Toads of Alabama is the most comprehensive taxonomy of the anuran fauna gathered since Robert H. Mount's seminal 1975 volume on the reptiles and amphibians of Alabama. This richly illustrated guide provides an up-to-date summary of the taxonomy and life history of frogs and toads both native and introduced to the state. Alabama possesses one of the most species-rich biotas in north temperate areas and this richness is reflected in its frogs and toads. The authors examine all known species within the state and describe important regional variations in each species, including changes in species across the many habitats that comprise the state. Significant field studies, especially of Alabama's species of conservation concern, have been performed and are used to inform discussion of each account. The life-history entry for each species is comprised of scientific and common names, full-color photographs, a morphological description, discussion of habits and life cycle, and a distribution map depicting the species range throughout the state, as well as notes on conservation and management practices. The illustrated taxonomic keys provided for families, genera, species, and subspecies are of particular value to herpetologists. This extensive guide will serve as a single resource for understanding the rich natural history of Alabama by shedding light on an important component of that biodiversity. Accessible to all, this volume is valuable to both the professional herpetologist and the general reader interested in frogs and toads"--
