From: Long-term patterns of an interconnected core marine microbiota
The monthly variation in the resident and core microbiotas over 10Â years. Upper panels: The resident microbiota is defined as those eukaryotes and bacteria that occur in at least 30% of the samples over 10Â years. The relative OTU abundance (left panel) and number of OTUs (right panel) for different domains and taxonomic levels in the resident microbiota are shown. Note that the relative abundance of Bacteria vs. Eukaryotes does not necessarily reflect organismal abundances on the sampling site, but the amplicon relative abundance after PCR. Relative abundances were calculated for each year and aggregated over the corresponding months along the 10Â years for the resident microbiota, then split into size fractions (NB: relative abundance for both domains and size fraction sums up to 1 for each month across ten years, see methods for details). Lower panels: Core microbiota over 10Â years. The relative abundances of core OTUs reflect the remaining proportions after removing all the OTUs that were not strongly associated when building networks.
