Response of pico-nano-eukaryotes to inorganic and organic nutrient additions

11 pages, 5 figures, 2 tables, supplementary data https://doi.org/10.1016/j.ecss.2019.106565Organic nutrient loading in coastal waters has considerably increased due to anthropogenic activities over the last decades. In particular, the increase in the proportion of organic vs. inorganic nitrogen may have an impact on microbial plankton communities, particularly within the small size classes, where mixotrophy is likely to be widespread. Here we explore the change in taxonomic composition of small eukaryotes (
