The Baja California peninsula is home to many forms of life found nowhere else on earth. This, combined with the peninsula's rugged and inaccessible terrain, has made the area one of the last true biological frontiers of North America. L. Lee Grismer is not only the foremost authority on the amphibians and reptiles of Baja California, but also an outstanding photographer. He has produced the most comprehensive work on the herpetofauna of the peninsula and its islands ever published. With its stunning color images, detailed accounts of many little-known species, and descriptions of the region's diverse environment, this is the definitive guide to the amphibians and reptiles of a fascinating and remote region. The culmination of Grismer's quarter century of fieldwork on the Baja peninsula and his exploration of more than one hundred of its islands in the Pacific Ocean and the Sea of Cortés, this book gives information on the identification, distribution, natural history, and taxonomy of each species of amphibian and reptile found there. Preliminary accounts of the life history of many of the salamanders, frogs, toads, turtles, lizards, and snakes are reported here for the first time, and several species that were almost unknown to science are illustrated in full color. The book also contains new data on species distribution and on the effect of the isolated landscape of the peninsula and its islands on the evolutionary process. Much of the information gathered here is presented in biogeographical overviews that consider the extremely varied environments of Baja California in both a contemporary and a historical framework. An original and important contribution to science, this book will generate further research for years to come as it becomes a benchmark reference for both professionals and amateurs.

The desert islands in the Sea of Cortez are little known except to a few intrepid tourists, sailors, and fishermen. Though at first glance these stark islands may appear barren, they are a refuge for an astounding variety of plants and animals. While many of the species are typical of the greater Sonoran Desert region, some are endemic or unique to one or two islands. For example, Isla Santa Catalina is home to the world’s only rattlesnake that has lost its ability to grow a rattle. Other islands host nesting birds, such as Isla Rasa, a tiny, flat flow of basalt lava that attracts nearly half a million elegant and royal terns and Heermann’s gulls each spring. The Desert Islands of Mexico’s Sea of Cortez is one of the few books devoted to the biogeography of this remarkable part of the world. The book explores the geologic origin of the gulf and its islands, presents some of the basics of island biogeography, details insular life—including residents of the intertidal zone —and provides a brief outlook for preserving this area. More than a simple guidebook, Aitchison’s writing will take both actual and armchair travelers through a gripping tale of natural history. Like the rest of our fragile planet, the Sea of Cortez and its islands are threatened by humans. Overfishing has eliminated or greatly diminished many fish stocks, and dams on rivers that once flowed into the gulf prevent certain nutrients from reaching the sea. The tenuousness of this area makes the book’s extraordinary photographs and the firsthand descriptions by a well-known teacher, writer, and photographer all the more compelling.

In this follow-up to Islands and Snakes, this book contains 15 chapters describing diversity and conservation of snakes on islands, with foci on selected island systems not previously summarized. Attendant topics include biogeography, plasticity and evolutionary responses to insular conditions, invasive species, importance and collapse of trophic systems, threats to insular snake populations, and strategies of conservation to save them. Chapters include descriptions of snake faunas on larger islands such as Borneo and New Guinea; reproductive biology of insular snakes; phenotypic evolution; physiology and growth patterns related to diet and environment; patterns of endemism; taxonomy of snake radiations; and history of invasions by snakes on islands. The final chapter presents a discussion of prospects and overview of conservation of snakes on islands. Chapters are contributed by international authorities on respective island-and-snake systems. The latter include some islands or archipelagos that are young, or of high importance, or support snake populations that were previously not well known. The content includes colourful photographs, informative illustrations, and in some cases synthesis of new data relevant to the importance of islands for understanding the ecological underpinnings and genesis of biodiversity. Each chapter is appropriately referenced with citations to scientific literature, and where useful, footnotes, tables and graphic information supporting the narrative of the respective subject matter. The overall presentation is intended to provide readers with an enhanced appreciation for islands and the spectacular snakes that might live there.

The first volume contains species accounts of the venomous lizards and elapid and viperid snakes found north of Mexico's twenty-fifth parallel. Volume two covers the twenty-one species of rattlesnakes found in the United States, Canada, and northern Mexico.

This book presents valuable and recent lessons learned regarding the links between natural resources management, from a Socio-Ecological perspective, and the biodiversity conservation in Mexico. It address the political and social aspects, as well as the biological and ecological factors, involved in natural resources management and their impacts on biodiversity conservation. It is a useful resource for researchers and professionals around the globe, but especially those in Latin American countries, which are grappling with the same Bio-Cultural heritage conservation issues.

West Southwest: Vertebrate Life in Southern California celebrates an amazingly diverse fauna with description, evolutionary background, geographic insight, and ecological detail. Southern California is a vast region of very different habitats – all with an abundance of unique species of plants and animals and all within a day’s drive. Southern California shares an evolutionary history with other areas of the Southwest, but it has its own identity. The book is not a field identification guide. Instead, the book provides the evolutionary history of species groups, details where the individual species occur and their habitat preferences, and how they avoid the perils of predation and human impact. Key Selling Features: Summarizes the evolutionary background and ecology of southern California’s vertebrates: freshwater fish, amphibians, turtles, snakes, lizards, birds and mammals. Reviews the history of southern California’s biotic communities from the coast to the deserts and their association with other areas of the Southwest. Discusses vertebrate design and how it affects performance and lifestyle. Extends and enhances the content of regional field identification guides. Includes 120 maps, figures and color plates.

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

The class Amphibia contains over 6,300 known species, 54% of which live in the neotropical region. They cannot tolerate the high salt content of sea water and are therefore the only vertebrates not to have colonized marine habitats (Capula, 1989). The class is divided into three orders. The largest, Anura, is divided into approximately 30 families and more than 4,500 spe-cies, ranging in size from a few millimeters to a couple of feet in length, and found in nearly every niche on earth. They have four limbs, the hind limbs typically being larger and modified for leaping or climbing. Most are external fertilizers. These species are also vocal, making sounds that range from squeaks to barks. In lentic environments, anuran breeding occurs in water bodies ranging from ephemeral pools to large permanent lakes (Richter-Boix et al., 2006). Most species deposit their eggs or live larvae in aquatic envi-ronments; these go through a larval phase (tadpoles) characterized by in-tensive morphological transformation—metamorphosis—to the juvenile stage, with an adult appearance; they then continue growing until the re-productive stage.

"This is the best book I've read about American bison and their habitat. It is vivid, concise, witty, erudite, first-hand, and up-to-date. Most important, it argues convincingly that the only way to assure survival of bison and their habitat in the wild is to establish a Great Plains National Park at least 5,000 square miles in extent."—David Rains Wallace, author of The Bonehunter's Revenge: Dinosaurs, Greed, and the Great Scientific Feud of the Gilded Age "Dr. Lott's scholarship is strong and thorough. American Bison presents an extensive, state-of-the-art review of key points of American bison that are unaddressed or under-addressed by previous books. Moreover, it does it in a popularized, often narrative form that makes the material comprehensible to the educated lay reader as well as to the bison scholar."—James H. Shaw, Department of Zoology, Oklahoma State University
