Sessile biotal components of a fresh-water ecosystem.



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 At present, the term is almost never used and has been replaced by the term “fouling.”

Pleurocerids are also significant functional components of aquatic ecosystems affecting periphyton community structure, abundance and diversity of other macroinvertebrate taxa, and populations of predators (Brown et al.
The high availability of habitats provided by the diversity of aquatic vegetation favors the establishment and development of several organisms, mostly the periphyton (WETZEL, 1981; WETZEL; LIKENS, 1991).

Examination revealed a diverse community of both high and low ionic condition periphyton species, which are common to nutrient enriched environments such as that found in Malibu Creek (Table 3).
So, the overwhelming contribution of sedimentary pigments in the depressions seems to be from autochthonous sources and major contributors are the plankton, pond weeds, periphyton, benthic algae and pigmented bacteria.

Periphyton diversity was slightly higher near the inflow.
Blaustein and Margalit (29) tested the experimental interaction of mosquito larvae, Culiseta longiarolata and immatures of Bufo viridis which largely feed on periphyton may create competition for natural food.
But finally, as we learned about the bedrock and the periphyton and the sedges and the Water Conservation District, our perceptions changed once again as we understood this endangered wetland in its own way as a built environment: both built by natural processes into a complex ecosystem over thousands of years, and built in the sense that the points of human intersection with this natural area are carefully controlled.
Unimpeded input of solar radiation results in elevated water temperatures and abundant periphyton (Feminella et al.
