Wetlands in semiarid Europe - how to cope with eutrophication

Objective



Research objectives and content The restoration of polluted aquatic environments has become a major worldwide task. This study contributes to the question of whether wetlands in semiarid Europe can be restored by simple and reasonable ecotechnologies such as biomanipulation of foodwebs, rather than using expensive water treatment plantsbecause environmentally-safe operation and effectiveness in such areas seem to be doubtful, The application of biomanipulation techniques in the model ecosystem Las Tablas de Daimiel (a Spanish National Park in the Objective region Castilla-La Mancha) appears to be a promising intervention approach toreduce eutrophication. Field- and laboratory investigations will study thecascading effects of the absence of mosquitofish and the competition betweenphytoplankton, periphyton and macrophytes. Manipulation of community inter- actions will then result in water quality improvement and biodiversity preservation as well. Thus, we will provide an ecological basis for the menagement of wetlands in Mediterranean Europe. Training content (objective, benefit and expected impact)
Fresh knowledge and skills on wetland ecology will be acquired. Wetlands as l important aquatic environments largely remain to be investigated ecologically. This new knowledge will help in specializing in wetland ecology and its management. These new skills can be applied throughout the community tocontribute to the protection and rehabilitation of valuable but endangered l aquatic environments.
