Heterotrophic activity of bacterioplankton along the gradients of the chlorophyll a concentration and water temperature in marine and limnetic ecosystems

Аннотация

The dependence of the heterotrophic activity of bacterioplankton (V, μg C L^–1 h^–1) on the concentration of chlorophyll a (Chl, μg L^–1) and the water temperature (T) was examined for lakes (37°29′–80°36′ N) and marine polar waters (69°16′–80°36′ N). It was shown that ~76% of the V variations was related to changes in Chl and T.
