The preeminent naturalists Albert Hazen Wright and Anna Allen Wright spent years assembling the wealth of material on frogs and toads appearing in this widely used handbook, the third edition of which was originally published in 1949. With abundant black-and-white photographs, colorful descriptions, journal notes from the field, and excerpts from the literature, their personalized natural history emphasizes amphibians observed in the wild. In a foreword to the 1995 paperback edition, Roy McDiarmid, a foremost specialist on frogs and toads, brings the book into historical perspective and supplies information to bring it up to date. Accounts of more than 100 species and subspecies cover such topics as common and scientific names, range, habitat, size, and general appearance, as well as color, structure, voice, and breeding. Separate keys are given for secondary sexual characteristics, eggs, tadpoles, families, and species. Generous quotations from the Wrights' field journals give the reader a sense of the problems and satisfactions of their work.

"The premiere reference book on the 108 species of frogs inhabiting North America north of Mexico. An unparalleled synthesis of the biology and behavior of all native and nonindigenous species, this two-volume, extensively referenced resource has been called the most important book ever published on North American anura. Color photographs and range maps accompany species accounts detailing information on etymology, nomenclature, identification, distribution, fossil record, systematics and geographic variation, life history and ecology, behavior, population and community biology, and conservation. This new edition of the text contains the following updates: Literature citations have been added from 2012 to 2021, now spanning from 1709 to 2021. Distribution maps have been updated, recording the decreased ranges due to declining amphibian populations. Photographs have been revised to ensure the highest digital quality. Anaxyrus williamsi and Lithobates kauffeldi, newly described species, have been included. An account is also included for Gastrophryne mazatlanensis, now recognized as occurring within the United States. Generic keys have been added. A brief section on N.A. frogs in history and art have been added. Nomenclature has been updated (Incilius for Ollotis). Now the only up-to-date and comprehensive resource for those trying to protect amphibians in the US and Canada, as well as for researchers and wildlife managers who study biodiversity"--

This book is a softbound reprint of one in a classic series of American natural history handbooks originally published in the 1930's through the 1950's. Each volume is identical to the original in content, with the exception of a new forward, part of which highlights changes in systematics during the past half century. This volume presents an in-depth discussion of the frogs and toads of Canada and the United States. An introductory section provides general information on distribution, anatomy, habitats, habits, voice, reproduction, development, and other topics. The bulk of the text is taken by identification keys and the systematically arranged species accounts. All species are treated as evenly as the available information allows. The text is illustrated, heavily referenced, and indexed. Synopsis copyright (c) 1996 by Biological Abstracts, Inc. (BIOSIS).

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.

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.

“A huge, beautiful compendium of 600 frogs from around the world, from the famed poison-arrow variety on up to the intriguingly named plaintive rain frog.” —Wired With over 7,000 known species, frogs display a stunning array of forms and behaviors. A single gram of the toxin produced by the skin of the Golden Poison Frog can kill 100,000 people. Male Darwin’s Frogs carry their tadpoles in their vocal sacs for sixty days before coughing them out into the world. The Wood Frogs of North America freeze every winter, reanimating in the spring from the glucose and urea that prevent cell collapse. The Book of Frogs commemorates the diversity and magnificence of all of these creatures, and many more. Six hundred of nature’s most fascinating frog species are displayed, with each entry including a distribution map, sketches of the frogs, species identification, natural history, and conservation status. Life-size color photos show the frogs at their actual size—including the colossal seven-pound Goliath Frog. Accessibly written by expert Tim Halliday and containing the most up-to-date information, The Book of Frogs will captivate both veteran researchers and amateur herpetologists. As frogs increasingly make headlines for their troubling worldwide decline, the importance of these fascinating creatures to their ecosystems remains underappreciated. The Book of Frogs brings readers face to face with six hundred astonishingly unique and irreplaceable species that display a diverse array of adaptations to habitats that are under threat of destruction throughout the world. “If you are a serious (and I mean serious) fan of the frog, you are in for a real treat.” —Boing Boing

Casting a wide net, this volume provides personal and professional information on some 445 American and Canadian naturalists and environmentalists, who lived from the late 15th century to the late 20th century. It includes explorers who published works on the natural history of North America, conservationists, ecologists, environmentalists, wildlife management specialists, park planners, national park administrators, zoologists, botanists, natural historians, geographers, geologists, academics, museum scientists and administrators, military personnel, travellers, government officials, political figures and writers and artists concerned with the environment. Some of the subjects are well known. The accomplishments of others are little known. Each entry contains a succinct but careful evaluation of the subject's career and contributions. Entries also include up-to-date bibliographies and information concerning manuscript sources.

Animals have been studied for centuries. But what are the most important and relevant reference and information sources in the zoological sciences? This work is a comprehensive, thoroughly annotated directory filled with hundreds of esteemed resources published in the field of zoology, including indexes, abstracts, bibliographies, journals, biographies and histories, dictionaries and encyclopedias, textbooks, checklists and classification schemes, handbooks and field guides, associations, and Web sites. A complete revision of the award-winning Guide to the Zoological Literature: The Animal Kingdom (1994), this new title includes extensive, up-to-date coverage of invertebrates, arthropods, vertebrates, fishes, amphibians and reptiles, birds, and mammals. In addition, the work features a detailed introduction by the author, as well as thorough subject, title, and author indexes.
