Periphyton

 

freshwater organisms that live attached to the underwater parts of riverboats, beacons, piers, and other man-made structures. The term was proposed by the Soviet hydrobiologist A. L. Bening in 1924. It was subsequently used to designate the overgrowth of marine hydroengineering structures with organisms. At present, the term is almost never used and has been replaced by the term “fouling.”

In DAZ-3 (estimated date AD 1750-1860) the diatom assemblage stabilized, periphytic diatoms dominated over planktonic taxa and small-sized fragilarioid diatoms as well as epiphytic Achnanthes minutissima increased.
minutissimum is periphytic and can tolerate small amounts of salt and is found in low nutrient to high nutrient environments (26), is a good initial colonizer on different habitats, and is present in both lotic and lentic environments with temperatures greater than 15[degrees]C (27).
Also, to the contribution of periphytic community, since in shallow environments, as wetlands, the increase in the water flow may cause the detachment of periphytic organisms, and then preventing the establishment of limits among the populations from the different compartments of the aquatic ecosystem.
