Periphyton as an important source of methylmercury in Everglades water and food web.

Journal of Hazardous Materials, 2020
Periphyton is ubiquitous in Florida Everglades and has a profound effect on mercury (Hg) cycling. Enhanced methylmercury (MeHg) production in periphyton has been well documented, but the re-distribution of MeHg from periphyton remains unknown.

Phytoplankton and Periphyton

1997
Most studies of Amazonian algae concentrate on phytoplankton. Taxonomy and aspects of community structure are discussed by Gronblad (1945); Forster (1969, 1974); Martins (1980); Scott et al. (1965); Uherkovich (1981); Uherkovich and Schmidt (1974); Uherkovich and Rai (1979); Thomasson (1971), and many others.

The influence of periphyton on the migration and transformation of arsenic in the paddy soil: Rules and mechanisms

, 2020
Periphyton, composed of algae, bacteria, protozoa, epiphytes, and detritus, is widely distributed on the surfaces of paddy soils. Little is known about the interactions between the periphyton and arsenic (As) in the paddy soil.

Phyco-Periphyton in an Oligotrophic Lake

Transactions of the American Microscopical Society, 1965
Much limnological literature over the last century has been concerned with problems of primary productivity. In lentic waters large enough in size to promote a harvestable standing crop of fish, there exists numerous biocoenoses which have not been sufficiently considered.

Modelling periphyton in irrigation canals

Ecological Modelling, 2010
Periphyton developments in water distribution canals induce major disturbances for system management, such as clogging problems when fixed algae are detached. Periphyton models can be used to simulate and improve canal management. The purpose of this paper is to review the periphyton models which integrate a hydrodynamic effect, and to discuss their ...

Linkages between hydrology and seasonal variations of nutrients and periphyton in a large oligotrophic subalpine lake

Journal of Hydrology, 2019
Periphyton is important to lake ecosystems, contributing to primary production, nutrient cycling, and benthic metabolism. Increases in periphyton growth in lakes can be indicative of changes in water quality, shifts in ecosystem structure, and increases ...

Periphyton bioconcentrates pesticides downstream of catchment dominated by agricultural land use.

Science of the Total Environment, 2019
Periphyton provides important ecosystem services in aquatic environments, including supporting diverse consumers. We studied pesticide bioconcentration in periphyton in a coastal marsh on Lake Erie.

Linking Microbial Activities and Low-Molecular-Weight Thiols to Hg Methylation in Biofilms and Periphyton from High-Altitude Tropical Lakes in the Bolivian Altiplano.

Environmental Science and Technology, 2018
The sources and factors controlling concentrations of monomethylmercury (MMHg) in aquatic ecosystems need to be better understood. Here, we investigated Hg transformations in sediments, periphyton associated with green algae's or aquatic plants, and ...

Periphyton-based aquaculture.

2020
Abstract Periphyton, the assemblage of attached aquatic plant and animal organisms on submerged substrates, has the same functions of oxygen and feed production as phytoplankton, but may be more stable and can be utilized more efficiently by fish.
