Note: Geographic distances in km
All F _ST estimates of protein-coding genes are significant after Bonferroni correction, but some (^*) of the 16S encoding gene are not significant after Bonferroni correction. Italicized F _ST represent comparisons between populations belonging to two geographical groups, EPR + GAR and PAR. Bold italicized F _ST estimates indicate highly genetic differentiation of functional genes between two populations, 23and 32°S, that are isolated from each other with the Easter Microplate intervening
