The zooplankton biomass of Lake Boeckella (Hope Bay, Antarctic Peninsula) is strongly dominated by the calanoid copepod Boeckella poppei Mrázek. This work analyses the grazing impact of this copepod on the two dominant fractions of phytoplankton, pico- and nanoplankton, and on the bacterioplankton. By means of in-situ experiments using microcosms, the following hypotheses were tested: (a) the early stages of the copepod mainly graze on phytoplankton; (b) the pre-adult and adult stages graze on… CONTINUE READING
