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.

Periphyton diversity in two different Antarctic lakes assessed using metabarcoding
, 2021 Antarctic lakes have generally simple periphyton communities when compared with those of lower latitudes. To date, assessment of microbial diversity in Antarctica has relied heavily on traditional direct observation and cultivation methods. In this study,

Epilithic biomass in a large gravel-bed river (the Garonne, France): a manifestation of eutrophication? [PDF]
, 2002 In order to evaluate the impact of outputs of the city of Toulouse (740 000 inhabitants) on the epilithic communities colonizing pebble banks in the river Garonne, a large gravel-bed river (eighth order), dry mass (DM), ash-free dry mass (AFDM) and ...

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 ...

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.
