DOWNLOAD EBOOK →This bulletin supplies checklists and keys for identification of Mexican snake species. This work arose partially out of a joint, active interest resulting from a collecting trip to Mexico in 1932. Additionally, in gathering information, the authors studied specimens in the United States National Museum and other collections. The authors acknowledge that this treatise can be revised over the years as new materials are found and described. Where available, the authors have included United States National Museum catalog numbers for type specimens in the species descriptions.

DOWNLOAD EBOOK →In the first bilingual work on the reptiles and amphibians of the US–Mexico border, top herpetologists come together to describe the herpetofauna of the states of this region, which includes more than 600 species of toads, frogs, salamanders, turtles, sea turtles, alligators, lizards, snakes, and sea snakes that are found along the almost 2,000-mile border between the two countries. Each chapter is devoted to one state—four in the US (California, Arizona, New Mexico, and Texas) and six in Mexico (Baja California, Sonora, Chihuahua, Coahuila, Nuevo León, and Tamaulipas)—with text in both English and Spanish. The chapters contain an introduction to the area, a review of the research, a sketch of the state’s physiography, and a description of the species present as well as the pertinent conservation issues they face. A color photo gallery includes images of nearly all species. Almost 40 percent of the featured native species are shared between the US and Mexico, reminding us that animals depend on the integrity of natural landscapes and proving the need for a comprehensive, bilingual reference to help lead a shared effort in the management and conservation of the borderlands.

DOWNLOAD EBOOK →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.
