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
The late 20th Century and the early 21st century has been characterized by an unprecedented deterioration of the environment of the earyh and the throes of one of the major extinction events of all time. New diseases have emerged. Unmitigated deforestation,desertation,erosion and salinization of soil,pollution of water and air,and thinning of the UV-protective ozone layer constitute dire ecological threats for life on the planet. This volume contains 12 dynamic chapters reated to amphibian decline; Viral and Bacterial diseases of amphibians,Fungal Diseases; Factors affecting Interspecific variation in susceptibility to Disease ,Digenitic trematodes and their relationship to amphibian declines and deformaties,Amphibian malformations,Ultra Violet-B radiation,pollution,impact of reactive nitrogen, evaluating the impact of pesticides,endocrine disrupting chemicals,role of petrochemicals and heavy metals,acidification,and its effects and climate change.

Book Description
Amphibian Conservation is the fourth in the series of Synopses of Conservation Evidence, linked to the online resource www.ConservationEvidence.com. This synopsis is part of the Conservation Evidence project and provides a useful resource for conservationists. It forms part of a series designed to promote a more evidence-based approach to biodiversity conservation. Others in the series include bee, bird, farmland and bat conservation and many others are in preparation. Approximately 32% of the 7,164+ amphibian species are currently threatened with extinction and at least 43% of species are declining. Despite this, until recently amphibians and their conservation had received little attention. Although work is now being carried out to conserve many species, often it is not adequately documented. This book brings together and summarises the available scientific evidence and experience relevant to the practical conservation of amphibians. The authors consulted an international group of amphibian experts and conservationists to produce a thorough summary of what is known, or not known, about the effectiveness of amphibian conservation actions across the world. "The book is packed with literature summaries and citations; a veritable information goldmine for graduate students and researchers. It also admirably provides decision makers with a well-researched resource of proven interventions that can be employed to stem/reverse the decline of amphibian populations." -John G Palis, Bulletin of the Chicago Herpetological Society
