要旨:
Realization of the rapid loss of species due to habitat destruction has
brought into focus the multiple dimensions of biodiversity and led to
the Convention on Biological Diversity. The biodiversity of inland
aquatic ecosystems has just started receiving some attention. Wetlands
whose conservation and wise use has been promoted by the Ramsar
Convention since 1971, are among the most threatened ecosystems because
they are directly destroyed as well as bear the impacts of all
anthropogenic activities in their watershed. Many of the well-known
wetland values are related to their biodiversity. Yet, our understanding
of their biodiversity is very poor. This introductory chapter elaborates
the background of the book and sets the stage for discussion of various
issues concerning the biodiversity in wetlands.
