Selective feeding on natural phytoplankton by Calanus finmarchicus before, during, and after the 1997 spring bloom in the Norwegian Sea
Article Abstract:
A three-month study conducted in the Norwegian Sea in spring 1997 focused on selective feeding by Calanus finmarchicus, a calanoid copepod. A preference for diatoms was exhibited by C. finmarchicus throughout the study, and dinoflagellates were selected before and after the spring bloom. Both groups existed in relatively low concentration before and after the bloom. Cyanobacteria, pelagophytes and 'green algae' were avoided during the entire period of study. Temporal variation of pigments, contribution to chlorophyll of selected phytoplankton groups, and taxon-specific grazing effect of C. finmarchicus are also discussed.

Metal uptake by phytoplankton during a bloom in South San Francisco Bay: implications for metal cycling in estuaries
Article Abstract:
The phytoplankton in South San Francisco Bay may be able to cycle about 60% of the annual input of Cd, Ni and Zn from waste-water treatment. Metal trapping may therefore be affected by factors that influence the frequency or intensity of phytoplankton blooms in estuaries. The 1994 spring phytoplankton bloom in the South San Francisco Bay was studied. Cu concentrations were not affected by the bloom.

Influence of microalgal biomass on absorption efficiency of Cd, Cr, and Zn by two bivalves from San Francisco Bay
Article Abstract:
Two clams from San Francisco Bay, Potamocorbula amurensis and Macoma balthica, were studied to determine how microalgal biomass affected absorption efficiency of cadmium, chromium and zinc. Absorption efficiencies found with pulse-chase protocols were used as a measure of bioavailablility.
