Book Description
"Grismer brings together an impressive amount of original field and laboratory research, supplemented with a thorough review of existing literature, to present a first-rate accounting of the Baja California herpetofauna. This book sets the stage for further research of the reptiles and amphibians of this remarkable region."—Robert Hansen, Editor, Herpetological Review "Grismer is without question the foremost authority on the herpetofauna of the Baja Peninsula; no one else could have produced such a detailed, comprehensive treatment of the amphibians and reptiles of the area. The book stands as a monument to Lee's many years of dedicated work on the Baja herpetofauna and will be the standard reference on the subject for many years to come."—Julian C. Lee, author of The Amphibians and Reptiles of the Yucatán Peninsula

Book Description
One of the most important hotspots of herpetological biodiversity in the United States, California is home to many endemic amphibians and reptiles found nowhere else on earth. Many of these taxa have unique ecological and morphological specializations, and their management is an important conservation challenge. Increasing climate change impacts, human development, and extreme drought mean many of these species face an ever-greater risk of extinction. California Amphibian and Reptile Species of Special Concern provides an up-to-date synthesis of the current state of knowledge regarding the biology and conservation risks faced by 45 of California’s most sensitive amphibian and reptile species. With the goal of enhancing management based on the best available science, the authors developed a novel set of risk metrics to identify special concern species and the threats they face, including population declines, range size and restrictions, and ecological specializations and niche restrictions. In addition to detailed species accounts, this book provides a quantitative analysis of the conservation status and pressing management issues facing individual species and the state’s amphibian and reptile fauna as a whole. The volume focuses on identifying threats, concrete recommendations for management and recovery, and future research needs. The text is complemented by detailed distribution maps, color photos, and graphs. Written in nontechnical language, California Amphibian and Reptile Species of Special Concern will be a valuable resource to a broad range of users from resource managers, field biologists, and academic herpetologists to students and recreational naturalists. Published in association with the California Department of Fish and Wildlife.

Book Description
Transportation of species to areas outside their native ranges has been a feature of human culture for millennia. During this time such activities have largely been viewed as beneficial or inconsequential. However, it has become increasingly clear that human-caused introductions of alien biota are an ecological disruption whose consequences rival those of better-known insults like chemical pollution, habitat loss, and climate change. Indeed, the irreversible nature of most alien-species int- ductions makes them less prone to correction than many other ecological problems. Current reshuffling of species ranges is so great that the present era has been referred to by some as the “Homogocene” in an effort to reflect the unique mag- tude of the changes being made. These alien interlopers often cause considerable ecological and economic d- age where introduced. Species extinctions, food-web disruptions, community alte- tions, ecosystem conversion, changes in nutrient cycling, fisheries collapse, watershed degradation, agricultural loss, building damage, and disease epidemics are among the destructive – and frequently unpredictable – ecological and economic effects that invasive alien species can inflict. The magnitude of these damages c- tinues to grow, with virtually all environments heavily used by humans now do- nated by alien species and many “natural” areas becoming increasingly prone to alien invasion as well. Attention to this problem has increased in the past decade or so, and efforts to prevent or limit further harm are gaining wider scientific and political acceptance.

Book Description
With its varied topography of coast, mountains, and desert, the San Diego region, considered one of the world’s biodiversity hotspots, boasts a rich variety of amphibians and reptiles—from the arboreal salamander to the green sea turtle to the secretive San Diego banded gecko and the red diamond rattlesnake. More than a field guide, this up-to-date, authoritative, conservation-oriented book is the first comprehensive resource on the herpetofauna of the region, which is unfortunately also known for its high number of endangered species. Jeffrey M. Lemm gives information on identification, habitats, biology, and the conservation status of all 88 amphibian and reptile species found in the San Diego region. Many of these animals can also be found in a wide area of Southern California and Northern Baja California, making this valuable guide useful for a wide geographic area and a must-have for outdoor enthusiasts, nature-lovers, and professionals alike. * Includes a special venom section written by Sean Bush of Animal Planet’s "Venom ER" * 160 color photographs illustrate the major habitats and all 88 amphibians and reptiles found in the region * 70 range maps pinpoint the locations of each subspecies * A new, easy-to-use taxonomic key by renowned herpetologist Jay Savage as well as line drawings of tadpoles and amphibian egg masses help make species identification simple

Book Description
A spectacularly illustrated field guide to the amphibians and reptiles of California California is home to more than 200 species of reptiles and amphibians that can be found in an extraordinary array of habitats, from coastal temperate rainforests with giant redwoods to southeastern deserts offering dazzling wildflower displays each spring. California Amphibians and Reptiles covers every species and subspecies in this biodiverse region of the United States, with outstanding color photography and in-depth species accounts that draw on the latest findings on taxonomy and distribution. Setting a new standard for regional field guides, this state-of-the-art guide will serve as the definitive reference for California’s amphibian and reptile fauna for many years to come. Covers all 209 species of amphibians and reptiles found in California Features hundreds of stunning photos that illustrate geographic and within-species variation as well as differences among males, females, and young Includes first-ever color images and species accounts for newly discovered species Shows every species and subspecies in full color on a white background Depicts all amphibian larvae in breathtaking color Detailed species accounts describe key identification features, similar species, habitat, range and elevation, activity and behavior, diet, reproduction, and conservation Provides updated status of all threatened, endangered, nonnative, and special concern species Accurate range maps reflect contemporary and, where applicable, historical distributions in light of significant habitat loss across the state An invaluable resource for amateur naturalists, resource managers, and professional herpetologists

Book Description
"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"--
