Název v původním jazyce

Strong, weak, and missing links in microbial community of the N.W. Mediterranean Sea.

Popis výsledku v původním jazyce

Planktonic microbial communities often appear stable over periods of days and thus tight links are assumed to exist between different functional groups (i.e. producers and consumers). We examined short-term temporal correspondences in the concentrationsand activities of microbes sampled at a coastal marine site every 3 h for 3 days. We estimated the abundance and activity rates of the autotrophic prokaryote .i.Synechococcus./i., heterotrophic bacteria and nanoflagellates, viruses, and dissolved organiccarbon (DOM). We found that .i.Synechococcus./i., heterotrophic bacteria, and viruses displayed distinct patterns. .i.Synechococcus./i. abundance was greatest at midnight while viral concentrations were minimal. Bacterial production could be related toshifts in the grazing rates of heterotrophic nanoflagellates and viral infection rates. Overall, we found weak links between DOM, or grazing, and bacterial activity, a possibly strong link between .i.Synechococcus./i. and viruses.
