The Reptiles And Amphibians Of The Dutch Caribbean

" Intended as a filed guide to the one hundred or so species of reptiles and amphibians that occur on the islands of the Eastern Caribbean, from Angulla and Sombrero in the north to Grenada in the South..." Cover.

Most of the islands of the Caribbean have long histories of herpetological exploration and discovery, and even longer histories of human-mediated environmental degradation. Collectively, they constitute a major biodiversity hotspot – a region rich in endemic species that are threatened with extinction. This two-volume series documents the existing status of herpetofaunas (including sea turtles) of the Caribbean, and highlights conservation needs and efforts. Previous contributions to West Indian herpetology have focused on taxonomy, ecology and evolution, particularly of lizards. This series provides a unique and timely review of the status and conservation of all groups of amphibians and reptiles in the region. This volume introduces the issues particularly affecting Caribbean herpetofaunas, and gives an overview of evolutionary and taxonomic patterns influencing their conservation.

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.
