Different interactions between bacterial genera were compared in the microbial networks of the high altitude (HA) and ultrahigh altitude (UHA) groups. a High-altitude Tibetans. b Ultra-high-altitude Tibetans. Nodes represent bacterial genera, and the size represents the relative abundance (larger circle indicates greater abundance). Red line: positive correlation; blue line: negative correlation. Relative thickness of the lines represents the degree of correlation (greater thickness of the edges means a stronger correlation)
