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 provides detailed and updated knowledge about medically important 'Big Four' venomous snakes of India (Indian spectacled cobra, Indian common krait, Indian Russell's viper, and Indian saw-scaled viper). This book essentially covers the snakebite problem in the world with particular reference to Asia and India. It discusses the evolution and systematics of venomous snakes, emphasizing 'Big Four' venomous snakes of India; the evolution and composition of venoms determined by traditional biochemical and modern proteomic analyses. It also describes the pharmacological properties of enzymatic and non-enzymatic toxins of 'Big Four' venomous snakes of India. Different chapters discuss exciting topics such as species-specific and geographical differences in venom composition and its impact on pathophysiology and clinical manifestations of snakebite envenomation in India, biomedical application of Indian snake venom toxins; production and quality assessment of commercial antivenom, prevention, and treatment of snakebite in India, adverse effects of antivenom including strategies to combat antivenom reactions inpatient. This book caters to toxinologists, pharmacologists, zoologists, antivenom manufacturers, biochemists, clinicians, evolutionary biologists, herpetologists, and informed non-specialists interested to know about the Indian snake venoms.

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.

In this definitive work, Ernest Glen Wever establishes the evolutionary importance of the reptile ear as the origin of the higher type of auditory apparatus shared by man and the mammals. Tracing the development of the auditory receptor in the living reptiles, he examines the use of a variety of mechanisms and principles of action by that receptor. While some of the material in this book has appeared previously in journal articles, most of it is presented here for the first time. Basing this study on his twenty years of research at Princeton's Auditory Research Laboratories, Professor Wever treats in anatomical and functional detail the auditory mechanism in about 250 species and subspecies of reptiles. The anatomical treatment rests on dissections and histological examinations of the ears in serial section, and portrays the relevant features in drawings that represent particular views of reconstructions. The author evaluates the performance of thesse ears electrophysiologically, in terms of the electrical potentials of the cochlea, paying particular attention to problems of the transmission of vibrations inward to the cochlea and the actions there in stimulating the sensory cells. Professor Wever finds that the cochlea emerged independently from the non-auditory labyrinth in three different vertebrate groups: fishes, amphibians, and reptiles. It was among the reptiles, however, that the vertebrate ear took on a more advanced configuration from which it further evolved along separate lineages in the birds and mammals. Ernest Glen Wever is Eugene Higgins Professor of Psychology Emeritus at Princeton University. Originally published in 1978. 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.

Tortoises, those unmistakable turtles, evolved from a lineage that split off from the familiar pond turtles roughly 100 million years ago. Over time, these plant-eating land turtles spread around the world, growing to an enormous size (depending on the species) and living so long that they have become the stuff of legends. By most accounts, they are indeed the longest-lived of the turtles, with good records suggesting individuals may live as long as 180 years (anecdotal records suggest that some reach ages of 200 years or more). Providing the first comprehensive treatment of North America's tortoises, Biology and Conservation of North American Tortoises brings together leading experts to give an overview of tortoise morphology, taxonomy, systematics, paleontology, physiology, ecology, behavior, reproduction, diet, growth, health, and conservation. The contributors carefully combine their own expertise and observations with results from studies conducted by hundreds of other researchers. The result is a book that belongs in the library of every herpetologist. Contributors include: Gustavo Aguirre; L. Linda; J. Allison Matthew; J. Aresco Roy; C. Averill-Murray; Joan E. Berish; Kristin H. Berry; Dennis M. Bramble; K. Kristina Drake; Taylor Edwards; Todd C. Esque; Richard Franz; Craig Guyer; J. Scott Harrison; Sharon M. Hermann; J. Howard Hutchison; Elliott R.

This practical handbook of reptile field ecology and conservation brings together a distinguished, international group of reptile researchers to provide a state-of-the-art review of the many new and exciting techniques used to study reptiles. The authors describe ecological sampling techniques and how they are implemented to monitor the conservation status and population trends of snakes, lizards, tuatara, turtles, and crocodilians throughout the world. Emphasis is placed on the extent of statistical inference and the biases associated with different techniques and analyses. The chapters focus on the application of field research and data analysis for achieving an understanding of reptile life history, population dynamics, movement patterns, thermal ecology, conservation status, and the relationship between reptiles and their environment. The book emphasises the need for thorough planning, and demonstrates how a multi-dimensional approach incorporates information related to morphology, genetics, molecular biology, epidemiology, statistical modelling, animal welfare, and biosecurity. Although accentuating field sampling, sections on experimental applications in laboratories and zoos, thermal ecology, genetics, landscape ecology, disease and biosecurity, and management options are included. Much of this information is scattered in the scientific literature or not readily available, and the intention is to provide an affordable, comprehensive synthesis for use by graduate students, researchers, and practising conservationists worldwide.

Thailand is home to over 350 species of reptiles, consisting of many kinds of turtles and tortoises, lizards, snakes and crocodiless. With its extensive network of protected areas, Thailand is one of the richest and most ecologically diverse countries in the world. However, many of these species are being threatened more than ever before, including habitat loss caused by agricultural expansion and intensification, and from wildlife trade. For herpetologists and naturalists, understanding the reptiles of Thailand is now more important than ever before. With A Field Guide to the Reptiles of Thailand, Tanya Chan-ard, John Parr, and Jarujin Nabhitabhata present the definitive resource for identifying and understanding all known species of reptile in the region. It is the only updated and complete guide to the country's reptilian life in existence. The book contains an account of every species, complete with nomenclature, colour illustrations, and range maps of known locations. The accounts include discussion of behaviour, morphological measurements, and habitat, as well as the most current information on each species' conservation status. The authors explain the current system of classifying the threat level of endangerment, making the presented information and terminology understandable and useful. The introduction to the book discusses the history of herpetology in Thailand, as well as its climate, physiography, and zoogeography. A section on how to use the guide most effectively has also been included to make the book accessible to a wide range of both scientists and nature enthusiasts. A Field Guide to the Reptiles of Thailand is the definitive and most comprehensive resource for herpetologists, naturalists, and conservationists working in Thailand.

The discovery of stunning, feathered dinosaur fossils coming out of China since 2006 suggest that these creatures were much more bird-like than paleontologists previously imagined. Further evidence-bones, genetics, eggs, behavior, and more-has shown a seamless transition from fleet-footed carnivores to the ancestors of modern birds. Mixing colorful portraits with news on the latest fossil findings and interviews with leading paleontologists in the United States, China, Europe, and Australia, John Pickrell explains and details dinosaurs' development of flight. This special capacity introduced a whole new range of abilities for the animals and helped them survive a mass extinction, when thousands of other dinosaur species that once populated the Earth did not. Pickrell also turns his journalistic eye toward the stories behind the latest discoveries, investigating the role of the Chinese black market in trading fossils, the controversies among various dinosaur hunters, the interference of national governments intent on protecting scientific information, and the race to publish findings first that make this research such a dynamic area of science.

Lizards exhibit, in a form that is simpler to isolate and study, many of the same traits of higher vertebrates. For this reason, zoologists have long chosen lizards as model systems to address questions that are central to ecological and evolutionary theory. This books brings together many of the most active researchers currently using lizards to study the evolution of social behavior, plus three well-known experts on behavior of other taxa for an outside perspective. Each author begins by developing one or more hypotheses, then presents data on a specific lizard system that addresses these issues. The chapters are arranged in three sections that reflect the primary levels at which behavioral ecologists examine adaptive variation in social behavior: individual variation within populations, variation among different populations of the same species, and variation among several species.

Snakes comprise nearly 4,000 extant species found on all major continents except Antarctica. Morphologically and ecologically diverse, they include burrowing, arboreal, and marine forms, feeding on prey ranging from insects to large mammals. Snakes are strikingly different from their closest lizard relatives, and their origins and early diversification have long challenged and enthused evolutionary biologists. The origin and early evolution of snakes is a broad, interdisciplinary topic for which experts in palaeontology, ecology, physiology, embryology, phylogenetics, and molecular biology have made important contributions. The last 25 years has seen a surge of interest, resulting partly from new fossil material, but also from new techniques in molecular and systematic biology. This volume summarises and discusses the state of our knowledge, approaches, data, and ongoing debates. It provides reviews, syntheses, new data and perspectives on a wide range of topics relevant to students and researchers in evolutionary biology, neontology, and palaeontology.

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.

Islands and Snakes contains 13 chapters describing ecological systems with foci on snakes and their ecological roles on islands around the world. Each chapter is written by one or more authors who is an authority on that particular system. Summaries of research on the various islands are written in a narrative manner that includes science as well as personal insights in easily understood language. These varied vignettes of science feature islands around the world, and in all cases, fantastic species of snakes and their roles in the community of insular organisms in which they occur. Both challenges and opportunities associated with island life are discussed, as well as the unique attributes of snakes and their conservation as unique and important parts of nature. Chapters include colorful photographs and illustrations, and collectively they convey information on topics that include ecology, behavior, biogeography, physiology, adaptation, and evolutionary biology. An introductory chapter presents a review and perspective on the historical importance of island ecology and how snakes have contributed to our understanding of evolution and adaptation. The other chapters focus on snakes inhabiting islands associated with Asia, Australia, South America, North America, the Caribbean, and Europe. The final chapter features the unique "table top islands" or tepuis of South America as examples of ecological islands where elements of biota have become isolated by geographic features of landscape similarly to oceanic islands.
