Alpha diversity comparisons between different methods in granivore (a), omnivore (b) and carnivore (c). Observed OTU, Shannon diversity and phylogenetic diversity were used to estimate alpha diversity. The median, first and third quartiles were shown in the box (middle bar represents median, upper bound the third quartile, lower bound the first quartile). The statistical significance was determined using a Student’s t-test with a Benjamini–Hochberg correction. ns: no significant difference; *: FDR < 0.05; **: FDR < 0.01; ***: FDR < 0.001
