Bacillariophyta

, 2020
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.

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.

Signal, Uncertainty, and Conflict in Phylogenomic Data for a Diverse Lineage of Microbial Eukaryotes (Diatoms, Bacillariophyta)

Molecular biology and evolution, 2017
Diatoms (Bacillariophyta) are a species-rich group of eukaryotic microbes diverse in morphology, ecology, and metabolism. Previous reconstructions of the diatom phylogeny based on one or a few genes have resulted in inconsistent resolution or low support
