"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"--
