Aulacoseira
Aulacoseira is a genus of freshwater centric diatoms, chain-forming algae with silica cell walls that are widespread and abundant in lakes and large rivers, with a fossil record reaching back to the Paleocene.
Cyclotella
Cyclotella is a genus of centric diatoms, single-celled algae with silica cell walls, common in the phytoplankton of lakes and widely used as an indicator of lake environmental change.
Diatom
Diatoms (Bacillariophyceae) are single-celled golden-brown algae with silica cell walls (frustules), 2–500 µm, 20,000 to 2 million estimated species, driving ~40% of oceanic carbon fixation and used in water monitoring and diatomite.
Fragilaria
Fragilaria, established by Lyngbye in 1819, is a genus of araphid freshwater diatoms forming ribbon-shaped colonies, widely used in paleolimnology to reconstruct past lake conditions.
Gomphonema
Gomphonema is a large, abundant genus of freshwater diatoms of single-celled algae. Described by Ehrenberg in 1832, it has silica cell walls shaped like a wedge or club.
Navicula
Navicula is a genus of boat-shaped biraphid diatoms, single-celled algae with silica cell walls, drastically revised since the late 1970s and used in stream water-quality assessment.
Tabellaria
Tabellaria is a genus of freshwater diatoms, single-celled algae with silica cell walls, that forms zig-zag colonies and is widely used in paleolimnology to reconstruct past lake acidity.
