This contribution has been edited from a working document, prepared by invited scientists attending a workshop in Konstanz, Germany, on the importance of external perturbations for short- and long-term changes in large lakes ecosystems, held from 21 to 26 October, 1991. It tries to assess our current understanding of the most important processes involved in the functioning of large lakes and to identify the currently most urgent research priorities in the fields of land-water interactions, physical processes, biogeochemistry and nutrient relations, remote sensing, biological interactions in food webs, and long-term monitoring programs.
