Diatom responses to TP and TN Of 137 OTUs included in analyses (>1% relative abundance in>1% of samples), TITAN identified 52 as decreasers (low P diatoms) and 49 as increasers (high P diatoms) along the TP gradient (Appendix S1: Table S3). Sum z scores for low P diatoms identified an assemblage change point at 96 µg TP/L (5 th and 95th percentiles of ...

Comparison between fluorometry and microscopy‐based phytoplankton assessments in the Laurentian Great Lakes

Limnology and Oceanography: Methods, Volume 24, Issue 5, May 2026.
Abstract Photosynthetic pigment fluorescence is commonly used in limnology and oceanography as a proxy for phytoplankton biomass. Fluorometry has been used to detect subsurface algal blooms, characterize dynamics of the deep chlorophyll layer, and to provide greater vertical resolution to phytoplankton monitoring.

Structure and functional genes associated with carbon, nitrogen, phosphorus, and sulfur cycling processes in periphyton: A comparison between natural and artificial rivers

River, Volume 5, Issue 2, Page 177-191, May 2026.
Network analysis of functional genes among prokaryotes, and eukaryotes in natural and artificial rivers. Abstract Periphyton in aquatic ecosystems plays vital roles in the elemental cycle process and is vulnerable to anthropogenic interference. However, few studies have explored the elemental cycles of carbon (C), nitrogen (N), phosphorus (P), and ...

Alternative stable states: Evidence from natural ecosystems and implications for ecological restoration

Ecological Solutions and Evidence, Volume 7, Issue 2, April–June 2026.
Ecosystems can occupy alternative stable states, maintained by positive feedbacks and critical thresholds. Recovery is often nonlinear, making simple driver reversal insufficient. Effective restoration should target critical thresholds, disrupt degradation‐reinforcing feedbacks and strengthen recovery‐promoting feedbacks.

A Systematic Review of Biofloc Technology and Periphyton in Giant Freshwater Prawn (Macrobrachium rosenbergii) Aquaculture

Aquaculture, Fish and Fisheries, Volume 6, Issue 2, April 2026.
Biofloc technology and periphyton‐based systems enhance the sustainable production of giant freshwater prawn (Macrobrachium rosenbergii). A PRISMA‐guided review (2005 – 2024) shows that BFT improves survival (75 – 78 %) and feed efficiency, while periphyton supports natural productivity in grow‐out.

Phytoplankton population structure of the Anzali wetland (2010 and 2011)

‬‭Majallah-i ̒Ilmī-i Shīlāt-i Īrān, 2016
Phytoplankton groups are very important producers in the Anzali wetland having a significant role in the quality and need to be constantly studied in term of their sequence and density.

Seasonal nitrate drawdown transitions lake ecosystems from phosphorus to nitrogen deficiency in annual cycles

Limnology and Oceanography, Volume 71, Issue 4, April 2026.
Abstract Phytoplankton biomass is often limited by nitrogen (N) and/or phosphorus (P). Quantifying the relative availability of N and P in an ecosystem is useful in indicating nutrient limitation status. In subtropical lakes, nitrate availability generally follows a seasonal pattern with maxima in the late winter/early spring and minima in late summer ...
