| Abstract |
Algal microfossils are especially powerful tools for ecological monitoring programs because they can be used to assess deterioration and/or recovery in aquatic ecosystems, even when direct historical data are not available. Sedimentary diatom and chrysophyte assemblages have been the most widely used retrospective indicators. These assemblages have repeatedly proven to be reliable indicators for evaluating present-day surface water quality in comparison with natural ('reference' or 'background') conditions. Within the last few years, many advances have occurred in algal microfossil research. The paper describes the applicability and strengths of these new approaches, and shows how they can be successfully integrated into ecological monitoring programs. |
