FIG 3.

Two-dimensional nonmetric multidimensional scaling (2D-NMDS; stress, 0.116) plot of Bray-Curtis similarity matrices of microbial communities in soil (brown circles), sand (green circles), clay (blue circles), cushion sand (yellow circles), and rock layer (red circles) of the NIT cover system, and underlying tailings at the Kam Kotia Mine (black circles), determined by high-throughput amplicon sequencing. Points represent the composition of a community, and the distance between any two points represents the difference between those two communities.
