Figure 4.

Abundance and distribution of epiphytic bacteria, at the family level, associated to macroalgal genera of the different macroalgal phyla: Chlorophyta (C), Heterokontophyta (H), and Rhodophyta (R). The scale in the upper left shows the correspondence between colors and abundance values of bacteria. Abundance was defined as the number of Presence/Absences of epiphytic bacteria, at the family level, reported for each macroalgal genus in the literature consulted (n = 32). The bacterial family were ordered from highest to lowest abundance value. Taxonomic classification corresponded to those used in the literature consulted (Table S5).
