FIG 3.

Estimates of alpha diversity for lake sturgeon gut microbial communities from all treatments across all developmental stages. The differences in the gut microbiota composition across the treatments at the different ages were evaluated using a two-way ANOVA. Each point indicates the mean value of the diversity index, colored by the different treatments. The four treatment groups are denoted S, Sp, GW, and GWp, as defined in the text. (A) Alpha diversity in the gut microbiota at each time point, as measured by the inverse Simpson diversity index. (B) OTU richness based on the number of taxa observed in the gut microbiota from all treatments and times.
