Host to more than one hundred species of reptiles and amphibians, the Savannah River Site, a 780-square-kilometer tract in South Carolina, is one of the most intensely studied areas of herpetological ecology in the world. This guide is a summary of basic information on the site's richly varied herpetofauna, from their taxonomy and distribution to their behavior and habitats. Keys to identify the adult and larval forms of the site's known species comprise the core of the guide. These keys are supplemented by maps, graphs, and illustrations as well as by information on habitats; population characteristics and distribution; behavior related to movement, feeding, and reproduction; morphology; and techniques for collecting specimens. The guide also includes information about special identification and study problems involving unresolved sighting reports; subspeciation; and venomous, edible, endangered, and introduced species. Finally, a bibliography gives not only the sources referred to in the guide but virtually all studies and reports based on herpetological research conducted at the Savannah River Site. The site-related publications are listed by author but can also be found through an index to the subjects they cover. Guide to the Reptiles and Amphibians of the Savannah River Site is a valuable one-volume introduction to the existing information on herpetofauna at the site and to the countless research opportunities the site still presents. Because it is clearly written and designed and lists most of the reptiles and amphibians found in Georgia and South Carolina, the guide is also useful to wildlife observers--professional and amateur--in those states.

With its varied topography of coast, mountains, and desert, the San Diego region, considered one of the world's biodiversity hotspots, boasts a rich variety of amphibians and reptiles--from the arboreal salamander to the green sea turtle to the secretive San Diego banded gecko and the red diamond rattlesnake. More than a field guide, this up-to-date, authoritative, conservation-oriented book is the first comprehensive resource on the herpetofauna of the region, which is unfortunately also known for its high number of endangered species. Jeffrey M. Lemm gives information on identification, habitats, biology, and the conservation status of all 88 amphibian and reptile species found in the San Diego region. Many of these animals can also be found in a wide area of Southern California and Northern Baja California, making this valuable guide useful for a wide geographic area and a must-have for outdoor enthusiasts, nature-lovers, and professionals alike.

Amphibians and reptiles (herpetofauna) are a significant but much-neglected component of the natural economy of the province of Alberta. The Amphibians and Reptiles of Alberta, Second Edition continues both as a field guide and a comprehensive natural history, builds on the strengths of the first with a richly illustrated text and colour photographs of the species taken by renowned wildlife photographer Wayne Lynch. The Amphibians and Reptiles of Alberta, First Edition won an Emerald Award for Environmental Excellence and an award from the Book Publishers Association of Alberta. This second edition has been thoroughly revised and updated. Nomenclature has been changed to reflect current thinking in the field. New photographs have been added, and maps and illustrations have been updated. This is the essential reference for Alberta herpetofauna.

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.

This guide is intended for use by both amateurs and professionals and allows convenient retrieval of field data and natural history accounts. Amphibians and Reptiles of Pennsylvania and the Northeast:
-- Contains complete and easy-to-use keys to all the reptiles and both the adult and larval amphibians of the Northeast.
-- Features high-quality photographs to illustrate all species of amphibians and reptiles in the region as well as significant color variations and life history stages.
-- Includes detailed spot-distribution maps of each species within Pennsylvania and outline maps of each species' distribution throughout the northeastern United States.
-- Presents extensive new data on the status and distribution of the amphibians and reptiles of Pennsylvania.

Lizards utilise many different niches across a large variety of habitats. As a result of selective pressures exerted by the particular environments, many lizards in similar habitats have been shown to exhibit convergent morphologies. The performance of a lizard, or any organism for that matter, is a fundamental attribute employed in its survival, and therefore significantly impacts its fitness. The study of an organism's functional capacity is fairly new, with relatively few studies published. In studies of lizard functional capacity, performance is most often defined as the whole organism's ability to conduct an ecologically relevant task, and measures thereof have included sprint speed, bite force and locomotor endurance, amongst others. Primarily, the study of whole-organism performance includes those performance aspects related to dynamic animal movements, and not more passive' performance aspects (such as immune function levels or reproductive output) or those performance traits measured within an organism (such as enzyme reaction rate). This book focuses on the thermal ecology, genetic diversity and functional role lizards have in ecosystems. It discusses the influence of light on visual discrimination of sexually dichromatic dewlap colour in male and female brown anoles; the tolerance to thermal stress in lizard embryos; the leiolepis guttata; the impact on habitat modifications of thermoregulation in coastal sand dunes; the convergence in morphology in lizards; and sexual dimorphism and thermoregulatory behaviour in the long-tailed spiny lizard.

Amphibians and reptiles represent an essential and interesting component of Wisconsin's wildlife. Eighteen species of amphibian and thirty-six species of reptile occupy landscapes across the state. They live in aquatic habitats that range from small streams to large lakes, and from open prairies to mature forests on land. These species are vital members of the biological communities in which they occur, acting as important predators, prey, and competitors, while also providing a wide variety of additional ecological functions. However, many amphibians and reptiles have experienced drastic population declines and even local extinctions in Wisconsin due to habitat loss and degradation, overharvesting, the introduction of invasive species, pollution, and other factors. This comprehensive volume, by an expert team of editors and contributors, consolidates the current state of scientific knowledge, aims to expand public knowledge and appreciation of Wisconsin's natural legacy, and brings out the herpetologist in all of us. This long-awaited, state-of-the-field synthesis also includes hundreds of color photographs and illustrations, state-level and North American range maps, dichotomous keys, and research and conservation anecdotes that will entertain and inform even the most dedicated nature lover. Amphibians and Reptiles of Wisconsin is set to become a lasting resource and armchair companion for anyone in the Midwest interested in the state's natural history and amphibian and reptile fauna.

This book presents current research in the study of the anatomy, ecology and conservation of turtles. Topics discussed in this compilation include the accumulation and tissue distribution of metals and other elements in sea turtles across the globe as bioindicators of marine pollution; the pathological findings and causes of mortality of sea turtles in the Canary Islands; the painted turtle as a model of natural anoxia tolerance; the evolutionary history of turtles and responses of freshwater turtles to drought.

Who was Richard Kemp, after whom the Kemp's ridley sea turtle is named? Is Wake's Gecko named after Berkeley's Marvalee Wake? Or perhaps her husband, David? Why do so many snakes and lizards have Werner in their name? This reference book answers these and thousands of other questions about the origins of the vernacular and scientific names of reptiles across the globe.

From "Agkistrodon piscivorus conanti," the Florida cottonmouth subspecies named for Roger Conant, to "Xantusia," the night lizard genera namesake of John Xantus, this dictionary covers everyone after whom an extant or recently extinct reptile has been named. The entries include a brief bio-sketch, a list of the reptiles that bear the individual's name, the names of reptiles erroneously thought to be associated with the person, and a summary of major--and sometimes obscure or even incidental--contributions made by the person to herpetology and zoology. An introductory chapter explains how to use the book and describes the process of naming taxa. Easy to use and filled with addictive--and highly useful--information about the people whose names will be carried into the future on the backs of the world's reptiles, "The Eponym Dictionary of Reptiles" is a handy and fun book for professional and amateur herpetologists alike.

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.

Fifty-two kinds of snakes can be found in the Southeast, almost half of all species native to North America. Filled with more than 300 color photographs and written by two of the region's most renowned herpetologists, this is the most comprehensive educational guide to the Snakes of the Southeast. At the heart of the guide are its heavily illustrated, fact-filled descriptions of each species and its habitat. Also included is a wealth of general information about the importance of snake conservation and the biology, diversity, and life cycles of snakes. Useful information about the interactions of humans and snakes is also covered: species that are likely to be found near houses, snakes as pets, what to do in case of a snake bite, and more.Clearly written, cleanly designed, and fun to use, the guide will promote a better understanding of the habitat needs of, and environmental challenges to, this fascinating group of animals.Features: Conservation-oriented approach Over 300 color photographs Nearly 50 distribution maps Clear descriptions of each species, including differences in the appearance of young and mature snakes Size charts, key identifiers (scales, body shape, patterns, and color), descriptions of habitat, behavior and activity, food and feeding, reproduction, predators and defense, and conservation

This volume provides an up-to-date guide to the identification, range, habitat, and status of snakes found within eastern and central North America, from west Texas, to western Manitoba, to the eastern seaboard. Species accounts are grouped by family (Blind Snakes, File Snakes, Boas and Pythons, Colubrid Snakes, and two families of venomous snakes) and illustrated with 251 color photos showing species, subspecies and most natural intergrades and color phases. The descriptive text combines details of appearance, naturally occurring color morphs, behavior, range/habitat, prey, and look-alikes with the authors' personal field observations. Enhancing the text are 98 distribution maps. For ease of use, photos, range maps, and descriptive text are presented on the same page. Introductory chapters explain snake taxonomy and habitats, and they survey the legal and safety issues that should govern any attempts to handle these animals. For the general reader curious about the identity of a backyard visitor, the resource manager or naturalist seeking an engaging and informative handbook, or the herpetologist seeking an authoritative single volume devoted only to snakes, ""The Bartletts' Guide and Reference"" provides a handy, detailed, readable, and richly illustrated guide.

"Horned 'toads' have long inspired curious humans, from ancient Indian rock artists and the earliest Spanish explorers to modern scientists. These lizards specialize on ants for food, employ distinctive defensive tactics for different enemies, arch their bodies to collect rainwater, and exhibit numerous other adaptations to arid environments. Wade Sherbrooke's wonderful book, packed with facts and personal insights, will give everyone from lay naturalists to seasoned field biologists a new appreciation for these magically bizarre animals."--Harry W. Greene, author of "Snakes: The Evolution of Mystery in Nature

"Written in language understandable by anyone, Sherbrooke's newly revised little book on horned lizards is an exceedingly useful reference that covers most of what is known about these interesting and unusual lizards."--Eric R. Pianka, author of "The Lizard Man Speaks

"Wade Sherbrooke has provided in this very readable book a concise introduction to the evolution and natural history of the horned lizards, their impact on human art, and their future in an increasingly human-dominated planet. No one has more first-hand knowledge of the life history of horned lizards than Dr. Sherbrooke, so this book represents more than a summary; Sherbrooke provides insight into the life and times of horned lizards as no one else could. Amateur and professional alike will find much to enjoy about this book."--Darrel Frost, American Museum of Natural History

Praise for the first edition:

"[This is] the horned lizard bible deluxe."--"Coevolution"

The literature on snakes is voluminous but overwhelmingly centered in the natural sciences, with little published about them in the fields of popular culture or the history of medicine. Focusing primarily on American culture and history from the 1800s, this study draws on a wide range of sources--including newspaper archives, medical journals, and archives from the Smithsonian Institute--to examine the complex relationship between snakes and humans.

All six species of sea turtles found in U.S. waters are listed as endangered or threatened, but the exact population sizes of these species are unknown due to a lack of key information regarding birth and survival rates. The U.S. Endangered Species Act prohibits the hunting of sea turtles and reduces incidental losses from activities such as shrimp trawling and development on beaches used for nesting. However, current monitoring does not provide enough information on sea turtle populations to evaluate the effectiveness of these protective measures. Sea Turtle Status and Trends reviews current methods for assessing sea turtle populations and finds that although counts of sea turtles are essential, more detailed information on sea turtle biology, such as survival rates and breeding patterns, is needed to predict and understand changes in populations in order to develop successful management and conservation plans. Table of Contents Front Matter Summary 1 Introduction 2 Units of Assessment 3 Conceptual Model of Sea-Turtle Abundance and Demography 4 Abundance and Trends 5 Demographic Rates 6 Integrating Demographic Information with Abundance Estimates 7 Cross-Cutting Issues:Data, Education, Permits, and Coordination 8 Conclusions and Recommendations References A Brief History of Alternative Genetic Markers B Population-Structure Models C Committee and Staff Biographies

Over the last four decades, threats from anthropogenic activities such as Bycatch, modification or destruction of critical habitats, and use or consumption of products from turtles along with inherent life history features of sea turtles have declined severely in population sizes. Recently, through modern research techniques, we have learned some important aspects of taxonomy, ecology and biology of these animals; those findings revealed the role of sea turtles in their ecosystems, migratory patterns, habitat use and the main population hotspots and conservation units. This book aims to address the current situation on sea turtle research, to provide an overview of the newest tools and techniques for research, but at the same time provide key elements on management of sea turtles and how they can be used for conservation purposes. Through the detailed description of each technique and case studies that this book contains, students, researchers and academics can properly raise their research questions and experimental designs, which consequently enable them to obtain results comparable to those reported in studies from journals of high impact.

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.

As in the previous editions, the book includes an extensive listing of the literature on Texas amphibians and reptiles that goes back to the historic writings of Berlandier, in the early nineteenth century, and is updated to reflect the most recent research.?Comprehensive distribution maps, updated references, and an exhaustive bibliography round out this latest edition of what has come to be widely recognized as the standard scientific guide and reference for professional, academic, and amateur naturalists interested in the herpatofauna of Texas.

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.
