Long-term microbial population dynamics can reveal how ocean microbiomes respond to environmental variation, but resolving within-species change requires suitable genomic references. We integrated 30 PacBio HiFi long-read metagenome-assembled genomes (MAGs) from the northwestern Mediterranean Sea with monthly Illumina...

The reductive TriCarboxylic Acid cycle, long considered restricted to anoxic environments, was detected in three phylogenetically distinct Campylobacterota lineages from oxygenated surface seawater, suggesting a previously unrecognized and unexpected niche for this pathway.

Beyond seasonality, long-term climatic oscillations may shape microbial populations, and recurrent seasonal mutations and non-synonymous to synonymous mutation ratios from multiple genes are found, together with signatures of positive selection coinciding with El Niño events in MiCRO.
