The abundance and composition of microbial communities were investigated during 2007 in Marennes Oleron Bay (France) in order to characterize the biological relationships governing the planktonic food web. Compared to the results of previous years, there was a lower abundance and a lower magnitude of variations in autotrophic and heterotrophic microbial entities in 2007. Using a Spearman rank correlation analysis, a significant link for biological abundance was only noted between bacteria and ciliates. However, an interesting relationship was highlighted between chlorophyll a and bacterial aminopeptidase and beta-glucosidase exoenzymatic activities. Two characteristic periods of virus-bacteria uncoupling were observed in spring and autumn 2007. Using... |
