Description
| - Pelagic food webs in 15 lakes from European mountains were investigated during ice-free seasons. Eight lakes were acidified: pH < 6, alkalinity < 20 eq/l. The total phosphorus (TP) was 0.5-12.5 g/l without relation to pH. In alpine catchments, the only lakes with TP > 5 g/l were Starolesnianské pleso and Jörisee III. Bacteria were more important in pelagic food webs, both in terms of biomass and of activities, than in lowland lakes. Heterotrophic protozoans were scarce. Total pelagic biomass (Tbi) was directly correlated with TP (log/log). Total heterotrophic microbial biomass (THMi) reached 8.1 to 170 g/l C, i.e. 5 to 90 of Tbi. The highest THMi were found in Bohemian Forest. In Starolesnianské pleso the highest phytoplankton biomass (PHY) and PHY/THMi ratio were observed. The lowest zooplankton (ZOO) to PHY and ZOO/Tbi ratios occurred in the lakes of Bohemian Forest and of Tatra Mts. The percentage of exudation in total primary production was higher at low total production (20-90 in alpinelakes
