Zooplankton feeding on algae and bacteria under ice in Lake Druzhby, East Antarctica
The feeding of the cladoceran Daphniopsisstuderi on algae and bacteria was investigated under ice in anultra-oligotrophic Antarctic lake from late autumn (May)to early spring (October) in 2004. D. studeri fed on both algaeand bacteria with estimated filtering rates of 0.048 and0.061 l ind-1 day-1),...
