Notably, the “browning” of surface waters increases light attenuation, thereby decreasing primary production, but also changes in fluxes and inputs of nutrient elements will affect primary production and community composition. The research in this group also address the impacts of reduced calcium of the biota.
The approaches cover large scale spatial and temporal models in the boreal zone, partly based on existing databases, and encompass biota from bacteria to fish. Field studies and experiments are important tools.
