Figure 3

Habitat depths of cichlids (A) and phototrophic OTUs (B). Shared letters on box plots indicate no significant differences, and pairs that do not share any letters in common were significantly different by the Tukey post hoc test between cichlid species and between OTUs in (A) and (B), respectively. Species abbreviations are shown in Table 1. Ecomorphs of cichlids abbreviated in parentheses are as follows: G, grazer; B, browser; Sr, scraper; So, scooper. Colours of OTUs indicate their phyla, and patterns are the same as in Figure 2. Networks between algal farms of cichlid species and OTUs denote the frequency of occurrence with square-root transformation. Asterisks indicate significance in standardised specialisation based on d’ measures: *=5%, **=1%, ***=0.1%.
