Benthic organic carbon release stimulates bacterioplankton production in a clear-water subarctic lake
We carried out a set of experiments in a small clear-water lake in northern Sweden during summer 2010 to assess the effect of organic C (OC) released from epipelic algae on pelagic bacterial production (BP). The release rate of OC (dissolved and particulate) from epipelic algae was ∼45.4 ng C m -2 h...
