DOI: 10.1002/jsfa.12403
Abstract: BACKGROUND Nitrogen (N) is the most limiting nutrient in rice production. N loss via denitrification and ammonia (NH3 ) volatilization decreases N utilization efficiency. The effect of periphyton, which are widespread soil surface microbial aggregates… read more here.

DOI: 10.1007/s11356-017-0747-y
Abstract: Although the effects of periphyton on water quality and its relationship with flow conditions have been studied by researchers, our understanding about their combined action in eutrophic shallow lakes is poor. In this research, four… read more here.

DOI: 10.1016/j.aquatox.2018.08.015
Abstract: In surface waters within agricultural catchments, periphyton - i.e., biofilms containing algae, heterotrophs, and associated detritus - is subjected to multiple stressors including herbicides. Although herbicide effects on periphyton are frequently studied, the focus has… read more here.

DOI: 10.1016/j.ecoenv.2019.05.004
Abstract: Selenium (Se) enrichment has been demonstrated to vary by several orders of magnitude among species of planktonic algae. This is a substantial source of uncertainty when modelling Se biodynamics in aquatic systems. In addition, Se… read more here.
