Productivity and Diversity of Phytoplankton in Relation to Copper Levels in San Diego Bay.

Abstract

Biomass, productivity, and composition of phytoplankton communities were assessed at three sites in San Diego Bay over a period of 1 year, Phytoplankton assemblages taken from regions of low copper levels (less than 1.0 ppb) were characterized by high productivity, biomass and diversity. Samples taken from regions of high copper levels (greater than 3.0 ppb) were less diverse but maintained high biomass and productivity. Phytoplankton tolerance to various copper concentrations was demonstrated by laboratory tests. These findings suggest that the phytoplankton assemblages found in copper-contaminated regions are more tolerant to high copper levels. (Author)
