This book introduces updated information on conservation issues, providing an overview of what is needed to advance the global conservation of freshwater decapods such as freshwater crabs, crayfish, and shrimps. Biodiversity loss in general is highest in organisms that depend on intact freshwater habitats, because freshwater ecosystems worldwide are suffering intense threats from multiple sources. Our understanding of the number and location of threatened species of decapods, and of the nature of their extinction threats has improved greatly in recent years, and has enabled the development of species conservation strategies. This volume focuses on saving threatened species from extinction, and emphasizes the importance of the successful implementation of conservation action plans through cooperation between scientists, conservationists, educators, funding agencies, policy makers, and conservation agencies.

The Ecology of Papua provides a comprehensive review of current scientific knowledge on all aspects of the natural history of western (Indonesian) New Guinea. Designed for students of conservation, environmental workers, and academic researchers, it is a richly detailed text, dense with biogeographical data, historical reference, and fresh insight on this complicated and marvelous region. We hope it will serve to raise awareness of Papua on a global as well as local scale, and to catalyze effective conservation of its most precious natural assets. New Guinea is the largest and highest tropical island, and one of the last great wilderness areas remaining on Earth. Papua, the western half of New Guinea, is noteworthy for its equatorial glaciers, its vast forested floodplains, its imposing central mountain range, its Raja Ampat Archipelago, and its several hundred traditional forest-dwelling societies. One of the wildest places left in the world, Papua possesses extraordinary biological and cultural diversity. Today, Papua’s environment is under threat from growing outside pressures to exploit its expansive forests and to develop large plantations of oil palm and biofuels. It is important that Papua’s leadership balance economic development with good resource management, to ensure the long-term well-being of its culturally diverse populace.
