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 ...

Combined stable isotope and gut contents analysis of food webs in plant-dominated, shallow lakes [PDF]
, 2003 1. To determine feeding links between primary producers, invertebrates and fish, stable isotope analyses and gut content analyses of fish were conducted on the components of four shallow, eutrophic to hypertrophic, plant-dominated lakes. 2.

Sensitivity of freshwater periphytic diatoms to agricultural herbicides [PDF]
, 2009 The biomonitoring of pesticide pollution in streams and rivers using algae such as diatoms remains difficult. The responses of diatomcommunities to toxic stress in streamwater are disturbed by the variations of environmental parameters.

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.

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.

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 ...
