Relative abundances of the dominant bacteria in the Hooded Crane and Domestic Duck samples. Bar represents means; error bars denote standard deviations; The lower case letters above error bar represents the statistically significant differences, as determined with the Kruskal-Wallis test (P < 0.05). The one with the highest alpha diversity is marked as “a”. The alpha diversity is compared with other values, and the difference is significant, marked as “b”. Significant with all three, marked as “c”
