Interaction between local hydrodynamics and algal community in epilithic biofilm [PDF]
, 2013 Interactions between epilithic biofilm and local hydrodynamics were investigated in an experimental flume. Epilithic biofilm from a natural river was grown over a 41 day period in three sections with different flow velocities (0.10, 0.25 and 0.40 m s-¹ ...

The Role of Periphyton in the Everglades
EDIS, 2010 SL310, a 3-page illustrated fact sheet by Pamela Brown and Alan L. Wright, defines periphyton, describes its role in nutrient cycling for the Everglades ecosystem, and explains the ongoing research related to periphyton in Everglades restoration ...

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 ...

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

Benthic grazing in a eutrophic river: cascading effects of zoobenthivorous fish mask direct effects of herbivorous fish [PDF]
PeerJ, 2018 Benthic grazing strongly controls periphyton biomass. The question therefore arises whether benthic grazing could be used as a tool to reduce excessive growth of periphyton in nutrient-enriched rivers.

The relationship between cellular protein content and selenium accumulation in freshwater microalgae
Integrated Environmental Assessment and Management, EarlyView.Abstract Variability in the bioconcentration of selenium (Se) by primary producers at the base of the food web results in uncertainty in predictions of bioaccumulation and ecological risk to higher trophic level organisms. Water chemistry, speciation of Se, and periphyton community composition have all been suggested as factors that contribute to ...

Effects of sedimentation and periphyton communities on embryonic rainbow smelt, Osmerus mordax [PDF]
, 2009 The decline of anadromous rainbow smelt (Osmerus mordax) populations has been suspected to be linked to anthropogenic causes. Increased runoff from agriculture and urbanization has led to additional sediment inputs and eutrophying compounds in rivers ...

The effect of periphyton on the light environment and production of Potamogeton perfoliatus L. in the mesotrophic basin of Lake Balaton [PDF]
, 2013 Light within the littoral zone affects the productivity and interaction between periphyton and its macrophyte substrate. The effect of periphyton on macrophyte photosynthesis, seasonal variation and vertical distribution of periphyton on artificial ...
