DESCRIPTION:Ignacio Rodriguez-Iturbe\, James S.McDonnell Distinguished Uni
 versity Professor\, Dpt of Civil & Environ. Eng.\, Princeton Univ.\nThe di
 versity of life on earth is essential for the functioning of the ecosystem
 s which make possible the well being of human societies. This Biodiversity
  is intimately linked to the dynamics of the water cycle on earth\, e.g.\,
  the hydrologic cycle. Among many other crucial factors\, both the habitat
  capacity of different regions as well as the dispersal mechanisms of diff
 erent species are linked to the dynamics of the water cycle and to geomorp
 hoclimatic characteristics of the different ecosystems. Thus\, the biodive
 rsity of freshwater fish depends on the runoff characteristics existing on
  the different parts of a river basin as well as on the structure of the d
 rainage network. Similarly\, the diversity of forests is very much depende
 nt on the rainfall regimes of the regions they occupy. Among the most impo
 rtant causes of biodiversity loss are the decrease of appropriate habitat 
 (particularly from conversion to agriculture) and the impact of anthropoge
 nic climate change. These two factors are studied in the possible reductio
 n of tree diversity in the Mississippi-Missouri River System.The controlli
 ng role of hydrologic dynamics on fish diversity in that system as well as
  in the vegetation of wetlands as the Florida Everglades is also examined.
 \n\nProf. Ignacio Rodriguez-Iturbe is an international recognized expert i
 n geophysical hydrology\, and was awarded the Horton Medal in 1998. In 200
 8\, he published with Prof. A. Rinaldo (EPFL-ENAC/ECHO) and others in the 
 May issue of Nature a report on rainfall and river networks as predictors 
 of fish biodiversity.\n\nLa conférence se terminera par un apéritif.
