1. Biological monitoring of lakes and rivers

Program collects data of fresh water phytoplankton, phytobenthos, aquatic invertebrates, fish and plants. It intends to reach sufficient data to assess biological quality of water bodies and monitor their change in time. The program is designed to answer the needs of ecological classification determined by Water Framework Directive. The program is managed by Finnish Environment Institute (SYKE). Regional centres for economic development, transport and the environment (ELY-centre) and Game and Fisheries Research (RKTL) are responsible for the field work. Observations are done in the monitoring of water quality network and in specially designed network for anthropogenically eutrophicated lakes and rivers. Monitoring frequency varies between the locations and measured elements.

2. Ecological interactions between zoo- and phytobenthos with regard to defense-mechanisms against grazing pressure

Benthic macroalgae communities of the arctic ocean provide habitat, protection, nursery and nutrition to a large number of invertebrates. In contrast to temperate and tropical regions the basic ecological interactions between zoo- and phytobenthos of the Arctic are little understood. Therefore this project for the first time investigates biological and chemical interactions between invertebrates and macroalgae on Spitsbergen/Svalbard (Koldewey Station) with special emphasis on defense mechanisms against grazing pressure. Initial diving-investigations will map the invertebrate fauna which is associated with the macroalgae; the following feeding-experiments with herbivorous animals aim to selectively identify generalists, generalists with preference or specialists. Additional bioassays serve to reveal structural and/or chemical properties of those plants, which affect a specific impact on the grazing of herbivores. Our investigations on the chemical protection of the algae against grazing focus on the basic mechanisms and the chemical structure of potent secondary metabolites carried out in cooperation with natural product chemists.
