S. islandicus strains have diverse spacer repertoires. (a) The total number of spacers encoded by each strain from each S. islandicus population. The average and standard deviation are shown. Populations were compared using a one-way ANOVA with Tukey's multiple comparison test (***p < 0.001). (b) The number of strains from the combined Mutnovsky population (2000 and 2010) (grey) or the Yellowstone population (black) that have each unique CRISPR spacer.
