Photosynthetic primary production in the Mesoproterozoic

open access: yesNew Phytologist, Volume 251, Issue 1, Page 64-80, July 2026.
Summary The Mesoproterozoic atmosphere had more CO2 and less O2 than at present. While the upper ocean was oxygenated, the deeper ocean was euxinic or ferruginous. Primary production was performed by Chlorobia, Cyanobacteria, Proteobacteria, and Archaeplastida.

Spatio‐Temporal Resolution of Microbial Functions and Taxa Associated With Cyanobacterial Harmful Algae Blooms Along a 500‐Km Aquatic Continuum in the Lake Erie Watershed

open access: yesEnvironmental Microbiology, Volume 27, Issue 10, October 2025.
The aquatic microbiome can influence cyanobacterial harmful algal blooms. Abundances of genes and transcripts for phosphorus acquisition, denitrification and nitrogen fixation were higher upstream, whereas in Lake Erie genes and transcripts for microcystin production were higher.
