This work relates to the other three freshwater diatom projects, but with an added dimension. Since benthic diatoms from ancient lakes are generally poorly understood and documented, any knowledge of ...

These tools were based on benthic diatoms, a major group of algae. Diatoms play a key role in the functioning of the ecosystems of oceans and freshwater basins and contribute approximately 25 per cent ...

In contrast, chlorophytes were usually diluted. The increase in diatoms was likely due to resuspension of meroplanktonic species from the bottom. The benthic retention hypothesis proposes that rapidly ...
