Seasonal pattern of relative read abundances (RRAs) in bison fecals within each of four functional groups.
(a,e) C3 graminoids, (b,f) C4 grasses, (c,g) non-N2-fixing eudicots, (d,h) N2-fixing eudicots for Kansas (a–d) and South Dakota (e–h) bison. All OTUs were aggregated to shared common genera. RRAs are only shown for the top 50 most abundant OTUs, which comprised an average of 90% of all reads. Data shown for 2011, 2013, 2014 for Kansas and 2014 for South Dakota.
