"The frogs, toads, salamanders, and newts that inhabit North America, numbering nearly 300 species, represent immense variation in form, habitat, distribution and ecology. This volume discusses the diversity of these animals in relation to the historical geography of the North American continent and portrays all of the formally recognized amphibian species to be found in the United States and Canada within a geographical context. Each species is presented with a color photograph, an account of its range, habitat and conservation status, and an up-to-date, full color range map that depicts its known occurrences in relation to the topography of the landscape. This volume reflects the enormous growth in interest about amphibians and increased intensity of scientific research into their biology and distribution that has occurred during the past two decades"--
A guide to amphibian species of the North American continent, excluding Mexico, including range maps, identification keys and detailed color illustrations.
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.
Presents a comprehensive guide to reptiles and amphibians of North America, and contains full-color illustrated photographs and drawings that describe eighty-two species, their body structure, habitats, and much more.
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.
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.
The book concludes with a discussion of the study of fossil salamanders as it relates to the development of a realistic phylogeny and classification of the group.
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.
Guide and reference to the snakes of Western North America.
Covering all mammals, reptiles, and amphibians of North America, this comprehensive guide gives general information on each species, such as behavior patterns, diet, dominant physical characteristics, and tips on where and when to look for each animal and how to approach it. 270 illustrations. Color range maps.
