Diatoms (Bacillariophyta) in Rivers,Diatoms are unicellular algae that possess a cell wall composed of silicon dioxide often highly ornamented, made up of two parts. Diatoms are very diverse and common in streams and rivers, with a significant role in primary production. The benthic diatoms, in particular, have developed successful st

Freshwater species do not form parenchyma, but are based on one of the three filamentous growth forms: (1) uniseriate, creeping filaments infrequently or frequently branched; (2) complex branched forms producing basal and vertical series of filaments forming a crust; and (3) multiseriate

Ecophysiology of River Algae,heir habitat, growth form, and specific physiological abilities. Water flow imposes limitations in the diffusion and availability of gases and resources, also in relation to algal size and growth form. Algae adapt physiologically to light scarcity or excess via photosynthetic mechanisms, as well as
