Fig. 2From: Cloacal swabs and alcohol bird specimens are good proxies for compositional analyses of gut microbial communities of Great tits (Parus major)a Relative abundances of bacterial phyla in different gut sections and cloacal swabs. b Heat map of the relative abundance of the 25 most abundant bacterial OTUs (accounting for a total of 89.5 ± 1.3% (mean ± SE) of sequences in the data set) in different digestive tract regions and cloacal swabs. Genus names provided on the right; U = unclassified genus within the given taxon; OTU numbers given in bracketsBack to article page
