Název v původním jazyce

Seasonal dynamics, composition and feeding patterns of ciliate assemblages in oligotrophic lakes covering a wide pH range

Popis výsledku v původním jazyce

Ciliates from ten lakes of pH 4.9 to 9 were studied using quantitative protargol staining and fluorescence microscopy approach. Ciliate numbers were low (200 cells/l) but in two lakes (to 21 000 cells/l). Nano- to microphytoplankton hunters and/or mixotrophic ciliates prevailed in all acidic lakes. Prostomes dominated particularly in acidified lakes. Among mixotrophs, oligotrichs were the most prominent. The picoplankton-feeders (stichotrichs, peritrichs and scuticociliates) were found important but never dominating. The lakes were clustered according to the contributions of distinct feeding pattern ciliate groups that followed the clustering based on chemical parameters. Scottish Lochnagar and an alkaline Mexican Lake Alchichica differed from the rest, which branched to Northern remote pristine lakes (Norway and Kola-peninsula) and Southern lakes (Pyreneans, Alps, Tatra Mts.). No marked differences were detected between the above-timberline and forest surrounded mountain lakes.
