Dominant archaeal genera in individual sample and the shared archaeal genera across ruminal samples. (A) Archaeal taxonomic composition of individual yak ruminal samples at the genus level. (B) Relative abundance of shared archaeal genera across yak ruminal samples, showen as a box plot of relative bacterial genera abundance shared by all samples with percentage on the X-axis. The boxes represent the interquartile range (IQR) between the first and third quartiles (i.e., 25th and 75th%, respectively), and the vertical line inside the box defines the median. The whiskers represent the lowest and highest values within 1.5 times the IQR of the first and third quartiles, respectively. Samples with a relative abundance exceeding those values for a given genus are represented as points besides the boxes. The groups are: indoor feeding regime (feed), pasture grazing regime (graze), and grazing and supplementary feeding regime (GSF).
