Abundance and distribution of epiphytic bacteria, at the level of phylum and class of Proteobacteria, associated to macroalgal genera of the different macroalgal phyla: Chlorophyta (C), Heterokontophyta (H), and Rhodophyta (R). Proteobacteria classes were included because some articles included this taxonomic level. The scale in the upper left shows the correspondence between colors and abundance values of bacteria. Abundance was defined as the number of Presences/Absences of epiphytic bacteria reported for each macroalgal genus in the literature consulted (n = 32). The bacterial phyla were ordered from highest to lowest abundance value. “Unclassified” are microorganisms that could not be classified in any group. “Unidentified” classified as bacteria, but could not be strongly identified. Taxonomic classification corresponded to those used in the literature consulted (Tables S2, S3).
