Live sieving of freshwater zooplankton: a technique for monitoring community size structure

Body size and food size in freshwater zooplankton.

We used double-label liquid scintillation techniques to measure the efficiencies with which eight different-sized zooplankton species ingested four cell types relative to a standard cell type (Chlamydomonas). Efficiency ratios (ERs: clearance rate on cell type X / clearance rate on Chlamydomonas) on the three ultraplankton (<5 mum in diameter) cells (a coccoid bacterium and the algae Synechococ...

Vertical Distribution of Zooplankton and Copepod Community Structure in the Straits of Malacca

Vertical distribution of zooplankton biomass and abundance, copepod taxonomic composition and species diversity were analyzed at eight stations during an oceanographic expedition along the Straits of Malacca. Samples were collected in vertical hauls (140 μm mesh using 45 cm diameter NORPAC net) from four depth strata. Zooplankton biomass was higher at 10-20 m depth in the central and southern p...
