Fig. 5: Differences in particle-associated (PA) community composition between the distinct water layers, in ice-covered and ice-free regions.

Enriched taxonomic families between each two consecutive depths (surface-epipelagic, epipelagic-mesopelagic and mesopelagic-bathypelagic), ordered according to labels between the panels. The y-axis represents the mean log2 fold-change for microbial families with more than 3 ASVs with log2 fold-change absolute value higher than 1 (standard error is smaller than the point). Positive value represent enrichment in deeper water layers and negative value represents enrichment in shallower water layer. The numbers near the symbols represent the number of ASVs enriched in the depth. The x-axis is ordered according to the different taxonomic classes, represented by the color code.
