Abstract
ABSTRACT: We studied the effect of variable phytoplankton biomass and dominance of thediatom Skeletonema marinoi on the planktonic community respiratory carbon requirement over aperiod of 14 d (14 to 28 April 2008) in 3 different mesocosms filled with natural water at Espegrendmarine biological field station in Raunefjord, Norway. The carbon requirement was measured onmesozooplankton (the calanoid copepod Calanus finmarchicus) and 3 other size fractions of plankton—50% of the primary production, while bacterioplanktonshowed an intermediate and variable contribution (ca.
