Algal communities of humic acid sites: biomass and diversity in lake water versus peat-mat water

Luścińska M., Soska R.

Polish Journal of Ecology

1998

Vol. 46, no 2

123-135

In the water of a humic lake, and in the peat-bog surrounding it, there were recorded 70 taxa of algae: Cyanophyta, Pyrrophyta, Cryptophyta, Chrysophyta, Euglenophyta and Chlorophyta. In the peat-bog water a higher variety of species and algal biomass was observed than in the lake water. The relatively low biomass of algae in the lake water, was produced by few nanoplanktonic species, i.e. mixotrophic flagellates from Cryptophyta, Pyrrophyta and Chrysophyta.The comparatively higher biomass was formed by peat-bog algae, both in the nearest neighbourhood of the lake and in the bog pine forest. Community of algae from the peat-bog differs also according to the distance from the lake.
