Diatoms have adapted over time to grow under a variety of environmental conditions which are often detrimental to other microalgae. Moreover, diatom dominance over other algae can be linked to their silica-based cell wall, which needs less energy to build than cellulose cell walls, resulting in a higher division rate. Diatoms a high nutrient uptake efficiency and a higher rate of nutrient utilization in comparison to other microalgae groups. In addition, the efficiency of light conversion into biomass is twice as high in diatoms. When analysing plankton–plankton interactions, diatoms emerged as the only group of phytoplankton with a large exclusion signal towards other planktonic groups, implying their ability to successfully outcompete congeners.
