View: 6016Transportation 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.

The book covers the origin and dispersal of plants, literature, use of medicinal plants within traditional Fijian culture, diseases of Fiji, and medicinal chemicals from plants. Four hundred and fifty plant species are described.The entries for species are arranged by plant family, and give current botanical name, Fijian or local name, brief botanical notes, medicinal uses and chemistry. Separate indexes to plant species and Fijian names are provided, as well as a glossary of medicinal and botanical terms.This book may point the way to plants from which new and effective cures might be obtained.

View: 4358This book provides one of the first detailed examinations of the problems of nature-based tourism development in peripheral areas. A diverse range of environments is used to illustrate the challenges and difficulties of managing nature-based tourism resources. A central theme throughout the book is the degree of opportunity that nature-based tourism provides as the basis for peripheral region development.
