The overall model fit was highly significant (Adjusted R 2 = 0.2165, p < 0.001), indicating that the selected environmental factors could substantially explain the distributional variation in cryoconite bacterial communities.
For climatic variables, wind speed (r = 0.259, p < 0.01) and vapor pressure (r = 0.241, p < 0.01) showed significant correlations with species composition, while mean monthly temperature (r = 0.163, p = 0.033) and precipitation (r = 0.185, p < 0.01) approached significance thresholds.
