Abstract

Bacteria convert dissolved organic matter (DOM) into detrituslike particles and clump small particles into larger ones, which may then become available to higher consumers. Microbial aggregates produced in the laboratory from DOM and particles <100 µm (both sources derived from freshly collected North Sea macroalgae), were ingested by the epibenthic harpacticoid copepods Paramphiascella vararensis and Tisbe holothuriae in short-term laboratory experiments. The production of fecal pellets was used as an indicator of aggregate consumption. Results showed that between 1-3 pellets copepod-1 h-1 were produced by P. vararensis, independently of algal aggregate source and age. In contrast, T. holothuriae produced between 5-13 pellets copepod-1 h-1...
