Book Description
A dichotomous key (that is, one that gives the user only two choices at each level of morphological scrutiny), it is designed for use in college-level herpetology or vertebrate biology courses. It will be especially useful as an effective tool for teaching the principles of taxonomy and for introducing students to the systematics of amphibians and reptiles.

Book Description
The second edition of the Field Guide to Amphibians and Reptiles of Illinois offers up-to-date information on the state’s 102 species of frogs and toads, salamanders, turtles, lizards, and snakes. Detailed descriptions by the authors include habitats, distinguishing features, behaviors, and other facts, while revised range maps and full-color photographs help users recognize animals in the field. In addition, an identification key and easy-to-navigate page layouts guide readers through extensive background material on each species' population, diet, predators, reproduction, and conservation status. A one-of-a-kind resource, the Field Guide to Amphibians and Reptiles of Illinois is a definitive guide aimed at biologists, teachers, students, wildlife specialists, natural resource managers, conservationists, law enforcement officials, landowners, hobbyists, and everyone else eager to explore herpetology and nature in the Prairie State.

Book Description
One of the most important hotspots of herpetological biodiversity in the United States, California is home to many endemic amphibians and reptiles found nowhere else on earth. Many of these taxa have unique ecological and morphological specializations, and their management is an important conservation challenge. Increasing climate change impacts, human development, and extreme drought mean many of these species face an ever-greater risk of extinction. California Amphibian and Reptile Species of Special Concern provides an up-to-date synthesis of the current state of knowledge regarding the biology and conservation risks faced by 45 of California’s most sensitive amphibian and reptile species. With the goal of enhancing management based on the best available science, the authors developed a novel set of risk metrics to identify special concern species and the threats they face, including population declines, range size and restrictions, and ecological specializations and niche restrictions. In addition to detailed species accounts, this book provides a quantitative analysis of the conservation status and pressing management issues facing individual species and the state’s amphibian and reptile fauna as a whole. The volume focuses on identifying threats, concrete recommendations for management and recovery, and future research needs. The text is complemented by detailed distribution maps, color photos, and graphs. Written in nontechnical language, California Amphibian and Reptile Species of Special Concern will be a valuable resource to a broad range of users from resource managers, field biologists, and academic herpetologists to students and recreational naturalists. Published in association with the California Department of Fish and Wildlife.

Book Description
From fishy beginnings, reptiles and amphibians have evolved into many different kinds of animals. This title helps you learn about creatures that live on the land, those that live in the water, and some that live in both environments.

Book Description
Historically the management of public lands from a multiple use perspective has led to a system that emphasizes those habitat components or faunal elements that primarily resulted in some sort of definable economic value. While this often benefitted other species that were not even considered in the original prescriptions, it also negatively impacted others. We no longer can afford to take this simplistic view of ecosystem management. We need to use a more holistic approach where ecological landscapes are considered as units, and land management practices incorporate all elements into an integrated policy. This includes examining the impacts of proposed land uses on amphibian, reptile, and small mammal populations.

Book Description
The first complete field guide to the exotic amphibians and reptiles established in the continental United States and Hawaiʻi, this volume covers 74 species that are not native to the country and 29 species that are native but occur beyond their original geographic range. Dispersed from their former habitats by human activity, many of these species are invasive in their new environments, causing ecological or economic harm. Ideal for naturalists of all levels, Exotic Amphibians and Reptiles of the United States details each species’ taxonomy, distribution, history, and ecology and portrays each one with vibrant photographs. Drawing on county-level distribution maps from 2,908 published records, this guide provides an in-depth understanding of local factors that drive the success of exotic species. It connects species-specific information to conservation issues as it explores human causes of exotic and invasive establishment. The book also includes eight invited essays which provide regional perspectives on scientific, economic, and management-related aspects of this phenomenon. As ecological pressures on native species and habitats increase, understanding the histories and roles of exotic species is becoming more and more important for conservation efforts. Providing practical identification skills and an awareness of the environmental impacts of these amphibians and reptiles, this indispensable guide equips readers to confront the unusual biodiversity crisis of exotic species.

Book Description
What makes a frog an amphibian but a snake a reptile? Both classes may lay eggs, but they have different skin coverings and breathe in different ways. Pages of fun facts will help kids identify each animal in the class like a pro after reading the fourth book in Arbordale’s Compare and Contrast series. Similar to Polar Bears and Penguins, Clouds and Trees; Amphibians and Reptiles uses stunning photographs and simple non-fiction text to get kids thinking about the similarities and differences between these two animal classes.

Book Description
Although reptiles and amphibians are different classes of vertebrates, they have long been studied together in the field of herpetology. This guide provides an account of the herpetology of Montana, first providing descriptions of herpetofauna biology, habitats in Montana, field observation, and conservation and management, then moving onto species accounts of 36 salamanders, frogs, toads, turtles, lizards, and snakes occurring in the western state. Including numerous color photographs, the species accounts provide information on morphology, taxonomy and distribution, habitat and behavior, and reproduction and development. Also provided are a simplified key to aid identification, a glossary, and appendices detailing reproductive features and other information.
