    Description: 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.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Loreau, M -- Naeem, S -- Inchausti, P -- Bengtsson, J -- Grime, J P -- Hector, A -- Hooper, D U -- Huston, M A -- Raffaelli, D -- Schmid, B -- Tilman, D -- Wardle, D A -- New York, N.Y. -- Science. 2001 Oct 26;294(5543):804-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratoire d'Ecologie, UMR 7625, Ecole Normale Superieure, 46 rue d'Ulm, F-75230 Paris Cedex 05, France.

    Description: The loss of biodiversity can have significant impacts on ecosystem functioning, but the mechanisms involved lack empirical confirmation. Using soil microcosms, we show experimentally that functional dissimilarity among detritivorous species, not species number, drives community compositional effects on leaf litter mass loss and soil respiration, two key soil ecosystem processes. These experiments confirm theoretical predictions that biodiversity effects on ecosystem functioning can be predicted by the degree of functional differences among species.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Heemsbergen, D A -- Berg, M P -- Loreau, M -- van Hal, J R -- Faber, J H -- Verhoef, H A -- New York, N.Y. -- Science. 2004 Nov 5;306(5698):1019-20.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Vrije Universiteit, Institute of Ecological Science, Department of Animal Ecology, de Boelelaan 1085, 1081 HV Amsterdam, Netherlands.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/15528441" target="_blank"〉PubMed〈/a〉
