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...

(English) The surface ocean harbours a vast diversity of microorganisms, including prokaryotes (bacteria and archaea), which are key drivers of global biogeochemical cycles. Understanding how these microorganisms respond to environmental variability requires linking patterns across different biological scales, from com...
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.
