On modeling chronic detachment of periphyton in artificial rough, open channel flow [PDF]
, 2012 Periphyton communities, which are native to river beds, serve as a functional indicator of river health but remain one of the least-studied communities despite the significant increase in the examination of aquatic microbial communities in recent years ...

Light increases energy transfer efficiency in a boreal stream. [PDF]
PLoS ONE, 2014 Periphyton communities of a boreal stream were exposed to different light and nutrient levels to estimate energy transfer efficiency from primary to secondary producers using labeling with inorganic (13)C.

Aquatic Insect Colonization and Substrate Changes in a Relocated Stream Segment [PDF]
, 2017 A section of Bear Creek in northwestern Wisconsin was relocated to accommodate new highway construction. The 850-m section of the stream was shortened to 650 m and fashioned with five broad bends and a uniform width and depth. Sandy substrate and lack of

The effects of nutrient level on periphyton–macrophyte interactions in freshwater ecosystems
Water Biology and SecurityPeriphyton are one of the key primary producers in aquatic ecosystems, particularly in oligotrophic shallow lakes. Submerged macrophytes are capable of competing with periphyton for nutrients and light, but may also facilitate periphyton by providing ...

Ranking stressor impacts on periphyton structure and function with mesocosm experiments and environmental-change forecasts. [PDF]
PLoS ONE, 2018 Streams are being subjected to physical, chemical, and biological stresses stemming from both natural and anthropogenic changes to the planet. In the face of limited time and resources, scientists, resource managers, and policy makers need ways to rank ...
