Abstract
A new method for investigation of the influence of sand grain composition on benthic microalgae has been tested. It lies in glueing of sand fractions of different size (< 0.25; 0.25—0.5; 0.5—1; 1—2; 2—3 mm) to the slides by silicone. It was revealed the valid increase in the microalgae abundance with increasing of relative substrate surface, i. e. there was a positive correlation between number of algae and percentage of fine sand grains.
