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. Study of the mechaninsms of inorganic carbon acquisition in macroalgae of the Swedish westcoast

The aim of our work was to study the occurrence of inorganic carbon pumps in the cell membrane and their importance in the supply of C for photosynthesis in different macrophyte species. This was performed by checking and comparing responses of several green, brown and, especially, red marine macroalgae species under CO2 disequilibrium conditions in the presence of buffer and/or inhibitors of carbon uptake. In addition, the effect of the different treatments was also checked in the marine phanerogam Zostera marina.
