Documents in comprehensive detail a major environmental crisis: rapidly declining amphibian populations and the disturbing developmental problems that are increasingly prevalent within many amphibian species.
Covering all 101 species of frogs in the United States and Canada, this book contains natural history information, identification tips, range and habitat information, summaries of behavior, and descriptions of calls. A 70-minute audio compact disc includes the calls of nearly every species.
"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.

These superb collections of field recordings and descriptions offer unparalleled access to the sounds and calls of numerous popular and less well known birds and amphibians. Each book and CD provides an introduction to the sound repertoire of species living in eastern and central North America--a variety of calls from each species are included, along with an in-depth description and explanation of their significance. In addition to color photographs of the most common species, the text offers a fascinating look at the science of avian and amphibian calls, making these guides indispensable aids for the outdoor enthusiast.
A young child eagerly reports on huge numbers of leopard frogs making a racket as they descend on a pond to mate! Readers will follow along as the narrator observes the leopard frogs' behavior up close, including their incredible transformation from young tadpoles to froglets and, finally, to adult frogs. Colorful photos, diagrams, and clear, age-appropriate text will engage young readers as they explore the life cycle, natural habitat, physical characteristics, diet, and behavior of these amazing amphibians. The diary format models scientific observation and critical thinking--and encourages children to keep notebooks recording their own investigations into the natural world.
Female northern leopard frogs can lay up to 6,000 eggs! The tadpoles will grow up into some of the quickest little amphibians around. Northern leopard frogs have a host of adaptations to help them hop through migration, hibernation, and breeding seasons. Early readers will be captivated by this informative title.
This book of photography represents National Geographic's Photo Ark, a major cross-platform initiative and lifelong project by photographer Joel Sartore to make portraits of the world's animals -- especially those that are endangered. His message: to know these animals is to save them. Sartore intends to photograph every animal in captivity in the world. He is circling the globe, visiting zoos and wildlife rescue centers to create studio portraits of 12,000 species, with an emphasis on those facing extinction. He has photographed more than 6,000 already and now, thanks to a multi-year partnership with National Geographic, he may reach his goal. This book showcases his animal portraits: from tiny to mammoth, from the Florida grasshopper sparrow to the greater one-horned rhinoceros. Paired with the prose of veteran wildlife writer Douglas Chadwick, this book presents an argument for saving all the species of our planet.
This is the first guide yet produced to the amphibians and reptiles of New York State, a large and heavily populated state that hosts a surprisingly diverse and interesting community of amphibians and reptiles. This much needed guide to the identification, distribution, natural history and conservation of the amphibians and reptiles of New York State fill a long-empty niche. The book is the first comprehensive presentation of the distributional data gathered for the New York State Amphibian and Reptile Atlas project. With more than 60,000 records compiled from 1990-1999, this extraordinary and up-to-date database provides a rich foundation for the book. This volume provides detailed narratives on the 69 species native to New York State. With a heavy emphasis on conservation biology, the book also includes chapters on threats, legal protections, habitat conservation guidelines, and conservation case studies. Also included are 67 distribution maps and 62 pages of color photographs contributed by more than 30 photographers. As a field guide or a desk reference, The Amphibians and Reptiles of New York State is indispensable for anyone interested in the vertebrate animals of the Northeast, as well as students, field researchers and natural resource professionals.
The definitive resource for finding, identifying, and conserving Maryland’s amphibians and reptiles. Naturalists, herpetologists, and ecologists alike agree that tracking herpetofauna is a challenging undertaking. Scientists are concerned about the decline of once-familiar species, but evidence has often been too anecdotal to support firm conclusions. To better understand the distribution of amphibians and reptiles in Maryland and forecast species' futures in a time of accelerated environmental threats, conducting a comprehensive statewide survey updating 1970s-era distribution maps seemed ideal. However, this endeavor was of an impossibly ambitious scope for scientists alone to tackle. Enter the Maryland Amphibian and Reptile Atlas project, comprising nearly a thousand dedicated citizen scientists who discovered and recorded the locations of herpetofauna throughout every corner of Maryland. In The Maryland Amphibian and Reptile Atlas, Heather R. Cunningham and Nathan H. Nazdrowicz present the findings of this massive undertaking. This definitive guide combines nearly 160 comprehensive new herpetological maps with historical distribution maps and in-depth species accounts. Color photos illustrate the natural history of the 89 species of frogs, salamanders, turtles, snakes, and lizards that call the state home. Essays discuss historical studies, the effects of Maryland's current climate, geology, and habitat diversity—and the myriad conservation issues these animals face. This richly detailed book represents a triumph of citizen science and the culmination of an intensive research partnership. It will appeal to both amateurs and professionals interested in herpetology, natural history, or ecology, as well as those with a special interest in Maryland's biodiversity.
