Tóm tắt

The ecological consequences of biodiversity loss have aroused considerable interest and controversy during the past decade. Major advances have been made in describing the relationship between species diversity and ecosystem processes, in identifying functionally important species, and in revealing underlying mechanisms. There is, however, uncertainty as to how results obtained in recent experiments scale up to landscape and regional levels and generalize across ecosystem types and processes. Larger numbers of species are probably needed to reduce temporal variability in ecosystem processes in changing environments. A major future challenge is to determine how biodiversity dynamics, ecosystem processes, and abiotic factors interact.

The conference “Biodiversity and ecosystem functioning: Synthesis and perspectives” was held from 6 to 9 December 2000 as a contribution to the International Geosphere-Biosphere Programme–Global Change and Terrestrial Ecosystems (IGBP-GCTE) Focus 4 and Diversitas Core Programme Element 1. We gratefully acknowledge financial support by the European Science Foundation the Centre National de la Recherche Scientifique (France) and the U.S. National Science Foundation. We thank all other conference participants for stimulating discussions.
