Interactions between Fe and light strongly affect phytoplankton communities in a eutrophic lake

The global increase in occurrence of harmful algae blooms in lakes has gained widespread attention. Although N and P are the main factors for primary productivity in lake ecosystems, dissolved iron (Fe) plays a crucial role as an essential micronutrient for phytoplankton growth. The interaction betw...
