Experimental Assessment of Epipelon Responses to Phosphorus Limitation in a Eutrophic Lake

Ecological Research, Volume 41, Issue 6, November 2026.
We evaluated the responses of epipelic algal and cyanobacterial communities to increasing phosphorus limitation in the water column under eutrophic conditions. Nitrogen enrichment increased the N:P ratio and intensified phosphorus limitation in the water column, promoting changes in community composition. The greater contribution of cyanobacteria (e.g.,

Organic‐matter sources and stability in kettle‐hole sediments: A combined thermogravimetric and isotopic approach

Agrosystems, Geosciences &Environment, Volume 9, Issue 3, September 2026.
Abstract Kettle‐holes are small but biogeochemically active landscape elements that integrate terrestrial inputs and influence carbon and nitrogen cycling. However, the stability and sources of organic matter (OM) in kettle‐hole sediments remain poorly understood.

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.

Exploring the Geodiversity—Biodiversity Relationships in Freshwaters for Environmental Conservation: A Global Systematic Literature Review

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 9, September 2026.
ABSTRACT Geodiversity refers to the heterogeneity of abiotic characteristics in nature, and in freshwater ecosystems, it mostly mirrors the diversity of hydro‐geomorphological features in inland waters. Although several scholars have highlighted that geodiversity contributes to habitat formation and influences biodiversity and ecological processes, it ...

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.

Contrasting Temporal Dynamics of Ostracod (Crustacea) Communities in Protected and Impacted Areas in a Brazilian Floodplain

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 9, September 2026.
ABSTRACT Environmental integrity is vital for the long‐term preservation of freshwater biodiversity, which is currently among the most threatened on Earth due to anthropogenic pressures such as dam construction. The present study investigated the temporal responses of ostracod communities over 8 years (2017–2024) in the Upper Paraná River floodplain ...

Seasonal Effect of a Small Hydropower Plant on Benthic Biofilm Microbial Community Structure and Predicted Functional Potential

Ecology and Evolution, Volume 16, Issue 9, September 2026.
Biofilm microbial composition varies significantly; diversity is higher in spring and autumn. The dewatered reach shows the broadest niche and dominant stochastic assembly. Seasonal assembly shift: deterministic in summer, stochastic in winter. Nutrient cycling genes vary more among sites than seasons under SHP influence.

Rapid phosphorus removal promotes a sustained decrease in nitrogen in eutrophic lakes

Limnology and Oceanography Letters, Volume 11, Issue 5, September 2026.
Abstract Excess phosphorus (P) leads to lake eutrophication, prompting interventions to reduce P availability. However, we have a limited understanding of how P availability impacts nitrogen (N), which also affects lake water quality. The in‐lake application of alum rapidly decreases P availability, presenting an opportunity to explore how P influences

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 ...

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 ...
