Název v původním jazyce

Bacteria and pelagic food webs in Pristine alpine lakes (Retezat Mountains, Romania)

Popis výsledku v původním jazyce

Nine lakes above timber line in Retezat National Park were investigated for pelagic biota (in 2000 ? 2001): bacterial abundances and biomasses, chlorophyll, and zooplankton species structure. In autumnal samples, bacterial abundances were in the range of0.049 ? 1.67 mill. per ml, bacterial mean cell volumes in the range of 0.083 ? 0.176 um^3, bacterial biomasses expressed in carbon between 1.25 and 61.21 ug C per litre and chlorophyll between 0.70 to 7.18 ug per litre. In all lakes Daphnia rosea Sars and Chydorus sphaericus Mueller were found. Cladocerans prevailed above copepods in all lakes except of two. Cyclopids were found in all lakes but one, whereas diaptomids were absent in 4 lakes. Two lakes were investigated 4 times during ice-free season.In Gemenele lake, primary production of phytoplankton was measured in August 2001 and found rather high, corresponding to an oligo-mesotrophic lake.
