Comparison of succession of reed periphyton in a degraded and in an undisturbed part of a shallow lake (Lake Velencei, Hungary, Central Europe)

Abstract

The decay of the influence of reeds on the succession of algae coating them was stuided. In the same lake, and at very close places, periphyton colonization was found to be significantly different. At a ’degraded’ point, the quantity of algae fluctuated with respect to both biomass and the number of individuals. The number of taxa was low in the first three weeks and began to grow only in the fourth week. The dominant species were also different.
