Abstract

Lentic (pools) and lotic habitats (streams) of Sphagnum bogs were studied, with the focus on the differences amongst the diatom assemblages. Regardless of the geographical location, the significant differences between the peat-bog pools and streams on the level of the measured abiotic variables (especially pH and concentrations of certain chemical elements), allow the existence of a much higher species richness and, therefore, diversity in the stream inhabiting diatom assemblages, as well as a strong majority separation between the two habitat types. However, for a reliable, comprehensive view of the living diatoms of a peat bog, both types of habitats need to be sampled simultaneously: lentic habitats seem to harbor the most extremophile species, while lotic habitats support the richest and the most diverse diatom assemblages with the highest presence of rare species.
