Book Description
"Ohio's resident amphibians currently include 25 species and subspecies of salamanders, a complex of unisexual ambystomatid salamanders, and 14 species of frogs and toads. Existing, comprehensive works of amphibians for Ohio are dated and out-of-print. Given this deficiency, and pressured by recent survey and monitoring activity and current research needs, the decision to produce a comprehensive book about Ohio's amphibians, which this volume represents, quickly followed. Focusing on verifiable information about the amphibian species of Ohio, the core of this tome is comprised of 37 chapters, organized by sections on salamanders and on frogs and toads, covering all amphibians in Ohio that have been documented and vouchered. Preceding these taxonomic, species-oriented chapters are sections on the history of herpetological work in Ohio, a summary of the Ohio environment in which its amphibian species exist, informative introductions to amphibian systematics, brief summaries of the two groups, and keys to adult and larval stages. Following the species accounts are sections on potential occurences in Ohio; on species ranking based on conservation status and knowledge; on amphibian conservation; on amphibian distribution; on environmental applications; and, a summary. Completing the book are two appendices involving field and vouchering/documentation techniques, a glossary, a combined and comprehensive listing of cited literature, and an index. This book is both scientifically accurate and written in a style suitable for the complete spectrum of individuals and entities who are professionally or casually involved or interested in amphibians"--Abstract, page iii.

Book Description
In 1990 an international group of biologists, meeting to discuss rumors of declines in the number of amphibians, discovered that amphibian disappearances once thought to be a local problem were not--the problem was global. And, even more disturbing, amphibians were disappearing not just from areas settled by humans but from regions of the world once believed to be pristine. Under the mantle of the Declining Amphibian Populations Task Force, this timely book addresses three fundamental questions for the midwestern United States: are amphibians declining; if so, why; and, if so, what can be done to halt these losses? In the Midwest--defined here as Missouri, Iowa, Illinois, Indiana, Ohio, Minnesota, Wisconsin, and Michigan--there can be no doubt that the number of salamanders and frogs has declined with Euro-American settlement and the conversion to an agriculturally dominated landscape. Habitat loss and landscape fragmentation have been major factors in this decline, as have aquacultural uses of natural wetlands. Bullfrog introductions have eliminated populations of native amphibians, and collecting for the biological supply trade has reduced the number of individuals within many populations. The goal of the forty-two essays in this well-documented, well-illustrated book is to put between two covers all we know now about the status of midwestern amphibians. By doing this, the editor has created a readily accessible historical record for future studies. Organized into sections covering landscape patterns and biogeography, species status, regional and state status, diseases and toxins, conservation, and monitoring and applications, this landmark volume will serve as the foundation for amphibian conservation in the Midwest.
