Metabolism and biomass vertical distribution of zooplankton in the Bransfield Strait during the austral summer of 2000
The vertical distribution (0?550 m) of zooplankton biomass, and indices of\nrespiration (electron transfer system [ETS]) and structural growth (aminoacyltRNA\nsynthetases activity [AARS]), were studied in waters off the Antarctic\nPeninsula during the austral summer of 2000. The dominant species wer...
