SUPPLEMENTAL MATERIAL
Figure S1. Rarefaction curves for each sample type with red
dotted line indicating the number of sequences to which the samples were
rarefied: A. blood, B. buccal, C. cloaca, D. intestine, E. gizzard, F.
liver, G. spleen.
Figure S2. Correlations between microbiota alpha diversity and
average bird weight using Observed (upper left), Shannon (upper right),
and Simpson diversity (bottom left) metrics; correlation and
significance values with and without controlling for phylogeny are also
reported (bottom right) for the (A) blood, (B) buccal, (C) cloaca, (D)
intestine, (E) gizzard body sites for all samples.
Figure S3. Correlations between microbiota alpha diversity and
average bird weight using Observed (upper left), Shannon (upper right),
and Simpson diversity (bottom left) metrics; correlation and
significance values (in green) with and without controlling for
phylogeny are also reported (bottom right) for the (A) blood, (B)
buccal, (C) cloaca, (D) intestine, (E) gizzard body sites for only
samples belonging to the order Passeriformes.
Table S1 . Metadata for all samples, including FMNH#, species,
body site and raw reads.
Table S2. Relative abundance of bacterial phyla for the seven
body sites. Phyla that were represented at below 10% of the sequences
within the sample were placed in the “Other” category. Samples are
separated by sample type.
Table S3. Pagel’s lambda (and significance) for bird weight,
using the species in each of the body site specific datasets.
