Warming and acidification effects on planktonic heterotrophic pico- and nanoflagellates in a mesocosm experiment
We studied the response of the heterotrophic flagellate (HF) community to the combined impact of warming and ocean acidification in a mesocosm experiment with a plankton community from the west- ern Baltic Sea. We performed a quantitative analysis of the response at the level of total biomass and si...
