Generously illustrated, this essential handbook for herpetologists, ecologists, and naturalists features comprehensive keys to eggs, embryos, salamander larvae, and tadpoles; species accounts; a glossary of terms; and an extensive bibliography. The taxonomic accounts include a summarization of the morphology and basic natural history, as well as an introduction to published information for each species. Tadpole mouthparts exhibit major characteristics used in identifications, and the book includes illustrations for a number of species. Color photographs of larvae of many species are also presented. Handbook of Larval Amphibians of the United States and Canada, written by the foremost experts on larval amphibians, is the first guide of its kind and will transform the fieldwork of scientists and fish and wildlife professionals.

Amphibian skin has, over the last century, proven to contain a treasure-trove of biologically active compounds. Since that time further investigation has added hundreds of such compounds to the list of active substances from amphibian skin. Peptides, proteins, bufadienolides steroids and alkaloids (tetrodotoxins, biogenic amines and lipophilic alkaloids) represent the main compounds found in the amphibian skin. This book discusses the anatomy of amphibians. It also provides topics on the ecological significant and conservation strategies of these marine animals.

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

In this book the authors present current research in the study of frogs. Frog's neuromuscular junction (NMJ) is a classic and favourite object which have played a leading role in developing understanding of the basic mechanisms of synaptic transmission and secretion of neuromediator. The genetic diversity, neural development and ecological implications of frogs are examined throughout the book. Some of the topics the authors discuss in this compilation include poison storage and maturation in serous cutaneous glands of anurans; a mini review of the suppression of anuran metamorphosis by synthetic chemical compounds; mechanisms of suprathreshold excitation of a frog tectal neuron column by discharge of a single moving edge or darkness detector and their relation to a frog escape reactions; behavioral, ecological, and evolutionary aspects of diversity in frog colour patterns; physiological features of blood's system of frogs rana ridibuda pall; and presynaptic voltage-dependent calcium channels at the frog neurmuscular junction.

With many frog populations declining or disappearing and developmental malformations and disease afflicting others, scientists, conservationists, and concerned citizens need up-to-date, accurate information. "Frogs of the United States and Canada" is a comprehensive resource for those trying to protect amphibians as well as for researchers and wildlife managers who study biodiversity. From acrobatic tree frogs to terrestrial toads, C. Kenneth Dodd Jr. offers an unparalleled synthesis of the biology, behavior, and conservation of frogs in North America.

This two-volume, fully referenced resource provides color photographs and range maps for 106 native and nonindigenous species and includes detailed information on- past and present distribution- life history and demography - reproduction and diet- landscape ecology and evolution- - diseases, parasites, and threats from toxic substances- conservation and management

In this book, the authors gather and present topical research from across the globe in the study of the biology, ecology and uses of frogs. Topics discussed include using frog red blood cells for exploring the ion transport pathways across cellular plasma membranes and their regulation; the significance of retinal glial cells for glutamatergic neural transmission in frog retina; a review of the intraspecific patterns and differences in life-history traits of frog populations living at different altitudes; the peripheral nervous system in the frog as a tool to examine the regulation of the transmission of neuronal information; ecological traits in the Omei treefrog in western China; taxonomic patterns of tadpole behavioural responses to alarm cues and frogs and toads used as bioindicator organisms in pollution studies.

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.

Reef Aquarium Success - Volume 1: Learn How To Maintain A Beautiful Mini-Ocean Environment Within Your Tank" is Volume 1 of the original electronic book "Reef Keeping Basics - Successful Reef Management." To assist in the marketing and promotion of that original book, the author - Eric V. Van Der Hope, decided to publish a paperback version of the book.

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.

This book covers bog frogs, spring peepers, and more.With more than forty native and introduced species of frogs and toads occurring in the southeastern United States, the region represents the heart of frog and toad diversity in the country. Renowned herpetologists Mike Dorcas and Whit Gibbons provide us with the most comprehensive and authoritative, yet accessible and fun-to-read, guide to these sometimes wet, sometimes warty wonders of nature.Dorcas and Gibbons enumerate the distinguishing characteristics of frogs and toads, including how they are different from other amphibians and the differences between a frog and a toad. Also discussed are the morphology of frogs and toads, the main groups to be found in the Southeast, and their habitats. Individual species accounts contain a physical description of the species plus information about distribution and habitat, behavior and activity, food and feeding, predators and defense, calls and vocalizations, reproduction and description of eggs and tadpoles, and conservation. Accompanying each account are photographs illustrating typical adults and variations and distribution maps for the Southeast and the United States.Given the recent worldwide decline in amphibian populations and increasing scientific and popular concern for what these declines mean for all other organisms, ""Frogs and Toads of the Southeast"" will appeal to people of all ages and levels of knowledge interested in natural history and conservation. The guide will help foster the growing interest in frogs and toads as well as cultivate a desire to protect and conserve these fascinating amphibians and their habitats.It provides a conservation-oriented approach. It includes approximately 250 color photographs. It contains approximately 45 distribution maps. It provides a clear description and photographs of each species in both tadpole and adult stages. It includes chapters on identification, vocalizations, reproduction, global diversity (including remarkable species such as the gastric brooding frog, poison dart frogs, and saltwater frogs), and introduced species.

Millions upon millions of salmon and steelhead once filled California streams, providing a plentiful and sustainable food resource for the original peoples of the region. But over the years, dams and irrigation diversions have reduced natural spawning habitat from an estimated 6,000 miles to fewer than 300. River pollution has also hit hard at fish populations, which within recent decades have diminished by 80 percent. One species, the San Joaquin River spring chinook, became extinct soon after World War II. Other species are nearly extinct. This volume documents the reasons for the decline; it also offers practical suggestions about how the decline might be reversed. The California salmon story is presented here in human perspective: its broad historical, economic, cultural, and political facets, as well as the biological, are all treated. No comparable work has ever been published, although some of the material has been available for half a century. In the richly varied contributions in this volume, the reader meets Indians whose history is tied to the history of the salmon and steelhead upon which they depend; commercial trollers who see their livelihood and unique lifestyle vanishing; biologists and fishery managers alarmed at the loss of river water habitable by fish and at the effects of hatcheries on native gene pools. Women who fish, conservation-minded citizens, foresters, economists, outdoor writers, engineers, politicians, city youth restoring streambeds-all are represented. Their lives-and the lives of all Californians-are affected in myriad ways by the fate of California's salmon and steelhead.
