Table 2. Initial concentrations of total chlorophyll a, diatoms and biomass of heterotrophic prey (dinoflagellates and ciliates) converted to carbon biomass (mgC l⁻¹), clearance rates (ml cop⁻¹ day⁻¹ ) and specific ingestion (% body C ingested day⁻¹ ) of Acartia clausi on chlorophyll a, diatoms, dinoflagellates and ciliates during the incubation experiments in control C and heat T treatments on Days 1, 9 and 19.

Error bars indicate± STDV of the mean.
