a decreasing trendP < 0.05
Bacterial 16S rRNA gene copy numbers showed a decreasing trend along the succession age ( P < 0.05), which had a significant correlation with TC ( r = 0.717, P < 0.001).

A total of 24 ARGs and two mobile genetic elements (MGEs) were detected from all the glacier samples, and the numbers of detected ARGs showed a unimodal pattern with an increasing trend at the early stage (0∼8 years) but no significant change at later stages (17∼50 years).
