Current velocity as factor affecting the periphyton biomass in karstic waters

The present study was an attempt at determining the response of periphyton biomass to current velocity in the karstic habitats on a travertine barrier. Organic mass (AFDM) and chlorophyll a content per unit surface, as variables indicating the periphyton biomass, could be associated nonlinearly with an increase of current velocity. The regression analysis showed that the exponential model y = ae-bx fitted the relation between periphyton biomass and current velocity satisfactorily.
