Aquatic Botany, 2019
Periphyton in aquatic ecosystems is comprised of algae, heterotrophic microbes, and detritus. In shallow lakes, periphyton is affected by substrate type, nutrient supply, and other factors.

Study of the effect of periphyton nutrient removal on eutrophic lake water quality
Ecological Engineering: The Journal of Ecotechnology, 2019To study the effect of periphyton on water quality, we chose to start our experiment in the summer, when microorganisms are active. In this study, we constructed six experimental groups to simulate eutrophic lakes and used polyurethane sponges as ...

Factors Affecting Sampling Variability of Freshwater Periphyton and the Power of Periphyton Studies
Canadian Journal of Fisheries and Aquatic Sciences, 1992Estimates of periphyton abundance, biomass (as biovolume, chlorophyll, dry mass, or ash-free dry mass), and production were reanalyzed to examine the effect of the mean value, sampler size, type of substratum, and habitat on the variance of these estimates.

Selenium oxyanion bioconcentration in natural freshwater periphyton.
Ecotoxicology and Environmental Safety, 2019Selenium (Se) enrichment has been demonstrated to vary by several orders of magnitude among species of planktonic algae. This is a substantial source of uncertainty when modelling Se biodynamics in aquatic systems.

Periphyton in a Stabilization System
Acta hydrochimica et hydrobiologica, 1990AbstractPeriphyton consisting of decomposers, producers and consumers proved to be an excellent indicator of the water quality in the course of selfpurification of dairy wastes in a stabilization system consisting of 3 reservoirs in Dvorec near Nepomuk.

Journal of Great Lakes research, 2019
Stable isotope ratios of carbon (δ13C) and nitrogen (δ15N) are frequently used to examine food web structure. Despite periphyton's importance to lake food webs, little is known about spatial variation of periphyton δ13C and δ15N values in the Great Lakes.

Groundwater discharge gives periphyton a competitive advantage over macrophytes
Aquatic Botany, 2019Lacustrine groundwater discharge (LGD) can significantly contribute to nutrient budgets of lakes. LGD usually occurs in shallow littoral zones, and thus, potentially affects periphyton and macrophytes.

Size Distribution in Periphyton
Canadian Journal of Fisheries and Aquatic Sciences, 1987When periphytic organisms growing on artificial plants were grouped in logarithmically increasing size classes, patterns in the distribution of biomass were consistent over the season and under different grazing regimes, despite taxonornical changes in the dominant taxa of algae and invertebrates.

Reaction of Lotic Periphyton to Experimental Acidification
Water, Air, and Soil Pollution, 1986Two hypotheses that could explain increases in the biomass and production of lotic periphytic communities in acidified habitats were tested: 1) a greater bioavailability of P due to its greater release from sediments at low pH, and 2) utilization of S from the H2SO4 addition.

Periphyton: Autoradiography of Zinc-65 Adsorption
Science, 1970The major site of sorption of zinc-65 in natural, matlike periphyton is on the upper surface of the community. There is a diffusion gradient within the community. Expression of results from short-term spiking experiments should thus be presented on an areal rather than gravimetric basis.
