Divergent Functional Roles of Shredder Size: Interspecific Versus Intraspecific Effects on Aquatic Leaf Litter Decomposition

Ecology and Evolution, Volume 16, Issue 1, January 2026.
Biodiversity enhances stream ecosystem efficiency, with greater taxonomic and trait diversity improving functions like decomposition. Shredder diversity arises from both species differences and ontogenetic variation. We experimentally examined these factors to reveal how they shape the magnitude and timing of organic matter processing in streams ...

Responses of Chironomidae (Diptera; Insecta) to the exclusion of shrimps and Ephemeroptera in a coastal forest stream, Rio de Janeiro, Brazil

Brazilian Journal of Biology
In a benthic community on a continuous flat granite substrate in a third-order coastal forest stream, the dominant chironomid (Cricotopus) increased in number when shrimps (Macrobrachium olfersi and Potimirim glabra) and baetid ephemeropterans were ...

Metagenomic Sequencing of Marine Periphyton: Taxonomic and Functional Insights into Biofilm Communities

Frontiers in Microbiology, 2015
Periphyton communities are complex phototrophic, multispecies biofilms that develop on surfaces in aquatic environments. These communities harbor a large diversity of organisms comprising viruses, bacteria, algae, fungi, protozoans and metazoans. However,

Small Hydropower Plants With Ecological Flow Influence Nestedness of Riverine Algae: Insights From treeNODF Analysis in Oujiang River Basin

Ecology and Evolution, Volume 16, Issue 1, January 2026.
Algal nestedness is significantly present in river ecosystems affected by small hydropower plants (SHPs). Environmental filtering drives functional and phylogenetic nestedness in SHP rivers. Reservoir habitats show greater complexity in SHP‐affected rivers.

Investigating the Role of Periphyton in Nitrification in Paddy Fields [PDF]

علوم آب و خاک
Soil 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 ...

Phytoplankton and Periphyton Primary Production in Clear and Turbid Shallow Lakes: Influence of the Light Environment on the Interactions between these Communities

Wetlands (Wilmington, N.C.), 2017
The ecological relevance of shallow lakes has been largely documented. The Pampean plain (Argentina) holds one of the main wetlands of South America, constituted by thousands of shallow lakes which provide valuable ecosystem services, and can be found in

Multiple stressors in river networks: local and downstream effects on freshwater macroinvertebrates

Ecography, Volume 2026, Issue 1, January 2026.
River networks are complex ecosystems characterized by a continuous exchange of material and energy through longitudinal gradients. These ecosystems are threatened by various human‐induced stressors, which frequently co‐occur and may interact in complex ways, potentially triggering cascading effects throughout the river network.
