Figure 1 Relative abundance of bacterial phyla. (A) Stacked
barplots showing the relative abundance of each phylum with each column
representing one individual sample, ordered by day of capture and
separated by sampling period. Phyla with total abundance less than 1%
and unclassified phyla are represented by gray. (B) Relative abundance
boxplots of the five most common phyla per individual by sampling period
representing the change in relative abundance from Cat Island, The
Bahamas (CIB) to the first Michigan recapture period (MI1) and the
second Michigan recapture period (MI2). Individual points represent the
relative abundance of each phyla per individual per sampling period.
Significance levels are pairwise comparisons between sampling periods
are shown (ns: p>0.05; * p<0.05; **
p<0.01; *** p<0.001; **** p<0.0001).
Figure 2 Alpha diversity measurements of amplicon sequence
variants (ASVs) including Observed ASV richness (log transformed, top
row) and Shannon Diversity index (bottom row) Boxplots of alpha
diversity at each sampling period (Column A). Individual points
represent the alpha diversity measure of the individual at that period.
Significance levels are pairwise comparisons between sampling periods
are shown (ns: p>0.05; * p<0.05; **
p<0.01; *** p<0.001; **** p<0.0001). Alpha
diversity change over time in the individuals sampled two (Column B) or
three times (Column C). Each line connects the measurements of the same
individual between the respective sampling periods. Continuous lines
represent a negative change in alpha diversity and dotted lines
represent a positive change.
Figure 3 Association between gut microbiome alpha diversity and
length of time birds have been in Michigan following end of Spring
migration. Each point shows alpha diversity of an individual bird. The
blue line represents the moving average between days
