Benthic diatoms and some environmental conditions in three lowland streams [PDF]
, 2002 This article reports on the ecological preferences of benthic diatoms in relation to pH, conductivity and organic pollution-eutrophication and their tolerance spectrums. Three Pampean streams subjected to different human impacts were studied.

Oikos, Volume 2026, Issue 3, March 2026.Food webs consist of trophic interactions of variable strength. However, it remains challenging to predict how changes in environmental conditions, such as nutrient enrichment, can affect these interactions. In this paper, we propose to integrate food web theory with ecological stoichiometry, which predicts how elemental ratios affect trophic ...

Water Resources Research, Volume 62, Issue 3, March 2026.Abstract Hydrodynamic and morphodynamic forces interacting across the sediment‐water interface control the biogeochemistry in the hyporheic zone. When investigating the redox zonation within streambeds, dissolved oxygen (O2) is considered a key solute to the understanding of river ecosystems.

Investigating the Role of Periphyton in Nitrification in Paddy Fields [PDF]
علوم آب و خاکSoil and water pollution and waste of resources have occurred due to the excessive use of nitrogen fertilizers in paddy fields. Considering that the biofilm of periphyton formed in paddy fields is mainly responsible for the exchange of nutrients, the ...
