Abstract

Phytoplanktonic biomass, species composition, and the main chemical parameters of the water were measured during summer stratification in 35 humic lakes in Finland. The lakes were situated in four chains with differing tropic status. Green algae were dominant in eutrophic lakes, blue-greens in mesotrophic, but cryptophytes and chrysophytes in oligotrophic brown waters. Diatoms were abundant in all types. The ecology of flagellated species, found significant for brown-water lakes, is discussed in relation to allochthonous loading of the lakes.
