Seasonal variation in zooplankton composition and grazing impact on phytoplankton standing stock in the Pearl River Estuary, China
The composition, abundance, distribution and grazing impact of dominant components of the meso- and macrozooplankton community were investigated in the Pearl River Estuary (PRE) wet and dry season cruises during the summer of 1999 and winter 2000, respectively. Throughout the investigation, mesozoop...
