Book Description
This book describes how the various alien reptiles and amphibians now living in the wild throughout the world were first introduced, how they subsequently became naturalized, their present distribution and status in those countries to which they were introduced, and their ecological and socio-economic impact on the native biota and local economies. Many species have had a more or less neutral impact, being neither beneficial nor harmful. However, several have had a positive ecological or socio-economic impact, while some such as the cane toad, have had an extremely destructive effect.The criteria for inclusion of a species are that it should have been imported from its natural range to a new country by human agency--either accidentally or deliberately--and that it should currently be established in the wild in self-maintaining and self-perpetuating populations unsupported by and independent of mankind.

Book Description
Tropical East Asia is home to over one billion people and faces massive human impacts from its rising population and rapid economic growth. It has already lost more than two-thirds of its forest cover and has the highest rates of deforestation and logging in the tropics. Hunting, coupled with the relentless trade in wildlife products, threatens all its large and many of its smaller vertebrates. Despite these problems, the region still supports an estimated 15-25% of global terrestrial biodiversity and is therefore a key area for conservation. Effective conservation action depends on a clear understanding of the ecological patterns and processes in the region. The first edition of The Ecology of Tropical East Asia was the first book to describe the terrestrial ecology of the entire East Asian tropics and subtropics, from southern China to western Indonesia. This second edition updates the contents and extends the coverage to include the very similar ecosystems of northeast India and Bhutan. The book deals with plants, animals, and the ecosystems they inhabit, as well as the diverse threats to their survival and the options for conservation. It provides the background knowledge of the region's ecology needed by both specialists and non-specialists to put their own work into a broader context. The accessible style, comprehensive coverage, and engaging illustrations make this advanced textbook an essential read for senior undergraduate and graduate level students studying the terrestrial ecology of the East Asian tropics, as well as an authoritative reference for professional ecologists, conservationists, and interested amateurs worldwide.

Book Description
Long celebrated for its more than 7,100 islands, the Philippines is a country in Southeast Asia that shares only with Madagascar the distinction of having been designated as both a Megadiverse Nation and a Global Biodiversity Conservation Hotspot. The terrestrial vertebrate fauna of the northeastern Philippines, specifically Luzon Island, has been the subject of intense interest since the first historical explorations. Historically, numerous works considered the biodiversity of Luzon as ?depauperate? in the sense that they was presumed to contain a reduced number of species shared with a continental mainland source. This view has persisted until recently, when a renewed interest in faunistic studies of the northern Philippines has produced a series of notable discoveries, drawing attention to high levels of species diversity and endemism in the northern reaches of the archipelago. We provide the first report on the herpetological biodiversity (amphibians and reptiles) of the northern Sierra Madre Mountain Range, northeast Luzon Island, Philippines. We combine new and historical data, and the results of recent fieldwork, to highlight at least 101 species present in this unique region of the archipelago. Not only is this fauna largely endemic (approximately 70%), but also our results add to a nascent body of literature suggesting that the northern portions of the archipelago may be substantially more diverse than currently appreciated.
