The Masked Role of Periphyton in Phosphorus Cycling: Mechanistic Insights Under Large‐Scale Hydrologic and Seasonal Variability

Water Resources Research
The role of periphyton in lake phosphorus cycling has long been overlooked or simplified, as water quality models often classify periphyton parameters as non‐sensitive, thereby masking their key roles in phosphorus cycling.

Non‐native pink salmon Oncorhynchus gorbuscha carcasses benefit native benthic macroinvertebrates

Journal of Fish Biology, EarlyView.
Abstract The invasion of the North Atlantic by pink salmon Oncorhynchus gorbuscha has raised concerns regarding their impact on coastal rivers. Although the influence of marine‐derived nutrients from returning adult O. gorbuscha on rivers in their native range has received much attention, the ecological consequences of invasive O.

Individual and combined effects of shading and habitat complexity on benthic macroinvertebrate communities in a mesocosm stream experiment (São Paulo, Brazil)

Restoration Ecology, EarlyView.
Abstract Introduction Agricultural activities are a major driver of biodiversity loss and ecosystem degradation in subtropical streams, often altering macroinvertebrate community structure and associated ecosystem functions. Although restoration strategies increasingly target these impacts, the relative importance of riparian shading and in‐stream ...

Consumption of periphyton and bioseston by Mozambique tilapia in aqua dams with three different substrates

Aquaculture Environment Interactions
Periphyton-based aquaculture can reduce feed input costs. Here we characterised the periphyton and bioseston formation in aqua dams stocked with net, plastic, and stone substrates.

Changes in food‐web pathways and ecosystem functions after sidearm re‐connection in a large river (Danube, Austria)

Restoration Ecology, EarlyView.
Abstract Introduction River regulation schemes generally led to changes in riverine assemblage composition and their trophic status, which often is reflected in a general loss or decrease of characteristic species and a concomitant increase or dominance of generalist species.

Phototrophic periphyton techniques combine phosphorous removal and recovery for sustainable salt-soil zone

, 2016
The P (P-i as KH2PO4 and P-o as ATP) removal processes by phototrophic periphyton were investigated by determining the removal kinetics, metal content (Ca, Mg, Al, Fe, Cu, and Zn) of the solution and P fractions (Labile-P, Fe/Al-P, Ca-P, and Res-P ...

Periphyton effects on bacterial assemblages and harmful cyanobacterial blooms in a eutrophic freshwater lake: a mesocosm study

Scientific Reports, 2017
Periphyton comprises a broad range of autotrophic and heterotrophic organisms that grow on submerged surfaces in aquatic environments. To investigate the ecological roles of periphyton and their symbiotic bacterial assemblages related to the control of ...

Topic Modeling of Fatty Acid Studies: Evaluating Environmental Changes in Freshwater Ecosystems

International Review of Hydrobiology, Volume 111, Issue 1, June 2026.
ABSTRACT Fatty acids (FAs) are biochemical molecules with vital structural and metabolic functions in all living organisms. Over the last decades, FA analysis in ecological studies has garnered significant attention due to its diverse applicability, such as taxonomic support for species identification, investigations on trophic interactions, and ...

Periphyton pigment shifts in lakes with varying water colour: a possible monitoring method for freshwater Browning

Ecological Indicators
Despite several negative effects of browning, there are no sufficient bioindicators to monitor it. In this study, the effects of water quality on the photosynthetic pigment content of periphyton grown on artificial substrata in different depths were ...

Fishmeal replacement by periphyton reduces the fish in fish out ratio and alimentation cost in gilthead sea bream Sparus aurata

Scientific Reports, 2021
Aquaculture threatens natural resources by fishing down the sea to supply fishmeal. Alternative protein sources in aquafeeds can provide a solution, particularly those that are waste from other operations and thereby reduce feed production costs.
