Sample name	Reads	OTUs	Simpson	Shannon	Chao	ACE	Goods coverage
HC	55564± 5369	940±108	0.97±0.01	6.79± 0.40	1048±118	1080±125	0.9962±0.0008
NC	57779± 6678	1138±197	0.97±0.02	7.27±0.60	1258±211	1276±190	0.9957±0.0005

Values are the mean ± standard deviation of six replicates. The number of reads, OTUs, richness estimator (Chao and ACE) and diversity estimator (Shannon and Simpson) were calculated at the 97% similarity level. NC = Mice raised in low altitude (2200 m above sea level); HC = raised in high altitude (5000 m above sea level).
