Fungi in the feces samples of Sceloporus grammicus Wiegmann found at 2600 m, 3100 m, and 4150 m as determined by ITS region barcode. Heat-map of the relative abundance of the most abundant taxonomic groups (a), non-metric dimensional analysis (MDS) of the Bray-Curtis distances of the three populations (b), and Venn diagram of the species of the core mycobiota (c). Kruskal-Wallis test (*p ≤ 0.05, **p ≤ 0.01, ***p ≤ 0.001) was used to determine the effect of altitude on the relative abundance of the different fungal groups and perMANOVA to find differences in fungal communities of the three populations
