Selenium Bioconcentration in Freshwater Periphyton [PDF]

, 2019
Selenium is an essential micronutrient for most forms of life, but it can elicit developmental toxicity in aquatic and semi-aquatic vertebrates, such as fish and waterfowl, through dietary exposure to excess organic Se compounds.

Effect of near‐bed turbulence on chronic detachment of epilithic biofilm: Experimental and modeling approaches. [PDF]

, 2010
The biomass dynamics of epilithic biofilm, a collective term for a complex microorganism community that grows on gravel bed rivers, was investigated by coupling experimental and numerical approaches focusing on epilithic biofilm‐flow interactions.

The potential of fish production based on periphyton

, 2002
Periphyton is composed of attached plant and animal organisms embedded in a mucopolysaccharide matrix. This review summarizes research on periphyton-based fish production and on periphyton productivity and ingestion by fish, and explores the potential of
