How did the zebra really get its stripes, and the giraffe its long neck? What is the science behind camel humps, leopard spots, and other animal oddities? Such questions have fascinated us for centuries, but the expanding field of evo-devo (evolutionary developmental biology) is now providing, for the first time, a wealth of insights and answers. Taking inspiration from Kipling's 'Just So Stories', this book weaves emerging insights from evo-devo into a narrative that provides startling explanations for the origin and evolution of traits across the animal kingdom. Held's unique and engaging style makes this narrative both enlightening and entertaining, guiding students and researchers through even complex concepts and encouraging a fuller understanding of the latest developments in the field. The first five chapters cover the first bilaterally symmetric animals, flies, butterflies, snakes, and cheetahs. A final chapter surveys recent results about a menagerie of other animals.

Crocodiles, alligators, caimans, and gharials-the Crocodylia, known collectively as crocodylians (or crocodilians)-are the world's largest living reptiles. The largest of them, probably the estuarine or saltwater crocodile, Crocodylus porosus, can grow to almost twenty feet and weigh more than two thousand pounds. Crocodylians are creatures of great contrast. They can remain patiently still for ages, yet can also move like lightning to snap up a meal. They are formidably strong, active predators, with jaws that can tear apart large prey items, yet a mother or a father can gently assist hatchlings out of the eggs, and carry them to the water between their teeth. Because large crocodylians can (and do) eat people, they invite fear and loathing, but they also inspire curiosity and admiration. Biology and Evolution of Crocdylians is a comprehensive review of current knowledge about the world's largest and most famous living reptiles. Gordon Grigg's authoritative and accessible text and David Kirshner's stunning artwork and color photographs combine expertly in this contemporary celebration of crocodiles, alligators, caimans, and gharials. This book showcases the skills and capabilities that allow crocodylians to live how and where they do. It covers the biology and ecology of the extant species, conservation issues, crocodilian-human interaction, and the evolutionary history of the group. Richly illustrated with more than five hundred color photographs and black-and-white illustrations, this book will be a benchmark reference work for crocodylian biologists, herpetologists, and vertebrate biologists for years to come.

In a collection rich in implications for all fields of ecology, leading lizard ecologists demonstrate the utility of the phylogenetic approach in understanding the evolution of morphology, physiology, behavior, and life histories. Lizards, which are valued for their amenability to field experiments, have been the subject of reciprocal transplant experiments and of manipulations of resource availability, habitat structure, population density, and entire sections of food webs. Such experiments are rapidly rebuilding ecological theories as they apply to all organisms. As a demonstration of state-of-the-art historical and experimental research and as a call for philosophical engagement, this volume will join its predecessors--Lizard Ecology: A Symposium (Missouri, 1967) and Lizard Ecology: Studies of a Model Organism (Harvard, 1983)--in directing ecological research for years to come. Lizard Ecology contains essays on reproductive ecology (Arthur E. Dunham, Lin Schwarzkopf, Peter H. Niewiarowski, Karen Overall, and Barry Sinervo), behavioral ecology (A. Stanley Rand, William E. Cooper, Jr., Emulia P. Martins, Craig Guyer, and C. Michael Bull), evolutionary ecology (Raymond B. Huey, Jean Clobert et al., Donald B. Miles, and Theodore Garland, Jr.), and population and community ecology (Ted Case, Robin M. Andrews and S. Joseph Wright, Craig D. James, and Jonathan B. Losos). Originally published in 1994. The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press. These editions preserve the original texts of these important books while presenting them in durable paperback and hardcover editions. The goal of the Princeton Legacy Library is to vastly increase access to the rich scholarly heritage found in the thousands of books published by Princeton University Press since its founding in 1905.

Lever describes the introduction of each reptile and amphibian now living outside its natural range as a result of deliberate or accidental movement by humans.The impact (positive or negative) these alien species have had on the regions to which they have been introduced is also discussed.

The foraging mode of lizards has been a central theme in guiding research in lizard biology for three decades. Foraging mode has been shown to be a pervasive evolutionary force molding the diet, ecology, behavior, anatomy, biomechanics, life history, and physiology of lizards. This 2007 volume reviews the knowledge on the effects of foraging mode on these and other organismal systems to show how they have evolved, over a wide taxonomic survey of lizard groups. The reviews presented here reveal the continuous nature of foraging strategies in lizards and snakes, providing the reader with a review of the field, and will equip researchers with fresh insights and directions for the sit-and-wait vs. wide foraging paradigm. This will serve as a reference book for herpetologists, evolutionary biologists, ecologists and animal behaviorists.

This book reviews comprehensively incubation effects on embryonic development in birds and reptiles and presents the first ever synthesis of data from these two vertebrate classes. The book is in three parts. The first deals with the structure, shape and function of eggs. The second examines the effects of the four main parameters on the process of incubation: temperature, water relations, respiratory gas exchange, and turning. The third section deals with early embryonic development and the methods used to investigate and manipulate the embryo. Further chapters deal with aestivation, megapodes and oviparity. International experts in each field have contributed to this extensively referenced volume and it will be of great interest not only to research biologists, but also to bird and reptile breeders, whether in commercial organisations or in zoos.

Scientists' views on what makes an experiment successful have developed dramatically throughout history. Different criteria for proper experimentation were privileged at different times, entirely new criteria for securing experimental results emerged, and the meaning of commitment to experimentation altered. In About Method, Schickore captures this complex trajectory of change from 1660 to the twentieth century through the history of snake venom research. As experiments with poisonous snakes and venom were both challenging and controversial, the experimenters produced very detailed accounts of their investigations, which go back three hundred years-making venom research uniquely suited for such a long-term study. By analyzing key episodes in the transformation of venom research, Schickore is able to draw out the factors that have shaped methods discourse in science. About Method shows that methodological advancement throughout history has not been simply a steady progression toward better, more sophisticated and improved methodologies of experimentation. Rather, it was a progression in awareness of the obstacles and limitations that scientists face in developing strategies to probe the myriad unknown complexities of nature. The first long-term history of this development and of snake venom research, About Method offers a major contribution to integrated history and philosophy of science.

This book, proposed as a companion volume to Professor Holman's Pleistocene Amphibians and Reptiles in North America (OUP 1995), presents, in detail, occurences of the herpetofauna in Britain and Western and Central Europe as well as discussions on the paleogeography, paleoecology, and evolution of these groups. The format follows in general that of the volume on North America, starting with an overview of the Pleistocene in Europe followed by a bestiary and chapters on identification of fossils, sites yielding fossils, range adjustments, evolutionary and extinction patterns, and origins of modern herpetofauna in Europe.

In the search for snakebite antidotes, the ecology and evolution of venomous snakes is of critical importance. This book presents a multidisciplinary approach to venomous snake research, as well as focusing on the medical aspects of snake venoms and the effects of snakebites. Herpetology is a growing subject, and this book will appeal to the ever-increasing number of amateur snake enthusiasts. The book will also be an essential reference work for researchers involved in any aspect of venomous snake research, as well as those interested in the broader fields of ecology and evolution.

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. 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.

Two-volume set.

Since the publication of The Venomous Reptiles of Latin America by Cornell University Press in 1989, scientific discoveries and taxonomic changes have resulted in the addition of many taxa and species to the herpetological fauna of the Western Hemisphere. This updated, heavily rewritten, and greatly expanded version of that book now includes accounts of all 192 species of venomous snakes and lizards found in the Western Hemisphere.

This two-volume set is illustrated with stunning color photographs, including portraits of venomous reptiles (many of which are unique in showing newly discovered species and views of male, female, and juvenile individuals); images of snakebites, an important tool for diagnosis and treatment; color vegetation and topographic maps; black-and-white photographs; line figures; and completely revised distribution maps.

Volume I includes a list of tables, preface, introduction, and regional/country accounts with related bilingual identification keys and vegetation and topographic maps. Genus and species accounts in this volume treat the lizards, coralsnakes, seasnakes, and all the pitvipers except rattlesnakes; these accounts are accompanied by color photographs of each species. Volume I also contains a complete index to both volumes.

Volume II includes descriptions of all known species of rattlesnakes. It also features four chapters by experts on mimicry, evolution, and snakebite treatment in tropical and temperate America. A glossary, literature-cited section, and index serve both volumes. Color photographs portray rattlesnakes, mimics, and the damage done by snakebite. The Venomous Reptiles of the Western Hemisphere is an essential reference for all naturalists interested in herpetology amateurs impressed by the beauty and complexity of venomous reptiles as well as professional herpetologists and their students conducting research in the classroom, at the zoo, and in the field."

Today, small populations of timber rattlesnakes (Crotalus horridus) quietly inhabit parts of Rutland County in Vermont, and Warren, Washington, and Essex counties in New York. Because the species is endangered, the exact locations of established dens in this area are a closely guarded secret. Insider, naturalist, and author Jon Furman has devoted years to the study of the snake's past and present range, its habitat and biology, the period in Vermont and upstate New York history during which timber rattlesnakes were ruthlessly hunted for a bounty, and the outlook for this severely threatened species in both states.
Soundly anchored in the latest scientific data, Furman proffers an accessible and engaging account of contemporary fieldwork and first-person interviews with herpetologists and old-time bounty hunters. For expert and lay readers interested in snakes and reptiles, northeastern fauna and natural history, conservation, and endangered species, this volume clearly explicates the timber rattlesnake's biology as well as what happens and what to do when one bites. It also explores the troubling decline of the northeastern population caused by bounty hunting between the 1890s and the early 1970s, other past and present threats to the species' survival, and what measures are being taken--and additional ones that must be taken--to ensure that timber rattlesnakes survive and thrive in the northeast. Historical and contemporary illustrations bring these reptiles and their world to life. Timber Rattlesnakes in Vermont & New York shines a new light on a maligned and misunderstood species.

Records of parasitism in crocodilians date back to the early 1800s, distributed among various types of published and unpublished materials. Analyzing parasite-host specificity, geographic distribution, and taxonomy can provide otherwise cryptic details about crocodilian ecology and evolution, as well as their local food web dynamics. This information is critical for improved conservation tactics for both crocodilians and their habitat. As climate change, anthropogenic conflict, and environmental pollution endanger crocodilian ecosystems, there is a need for organized information on crocodile, alligator, caiman, and gharial infectious diseases. This volume meets this need by delivering the first checklist of crocodilians and their parasites for researchers and scholars in biology, herpetology, and ecology in order to further the knowledge and study of crocodilian-parasite dynamics and improve our understanding of human impacts on ecosystems.
