“Y” represents “yes” for the three rightmost columns under “Core at.” SA, Saskatoon; ME, Melfort; and SC, Scott sites. The numbers in bracket indicate the number of amplicon sequence variants for that genus. Please see Supplementary Table S5 for full table showing their corresponding prevalence and relative abundance. ^∗There were two amplicon sequence variants for that genus.
