The biomass of spring and summer plankton consisted mainly of diatoms. Based on the species composition, phytoplankton biomass, concentration of chlorophyll a and TSI, the ur Reservoir was generally classified as moderately eutrophic with distinct trophic diversification of the water at particular studied sites. %K reservoir lake %K phytoplankton %K seasonal variation %K biomass %K chlorophyll %K physico-chemistry of waters %K trophy %U http://versita.metapress.com/content/t8v22326t2175gt6/?p=251e39c84a7443ec8f12ca7ff76e23c3&pi=0
