Fig. 5. Effects of environmental factors on homogeneous selection.

a Correlations under warming (orange) and control (aqua) based on Mantel test. This figure showed only the factors with significant correlations. See Supplementary Table 2 for other factors. b Multiple Regression on distance Matrix (MRM) under warming. c MRM under control. R², coefficient of determination based on the best model from Mantel analysis (see Supplementary Table 2 for details). The correlation was determined based on the difference (with a triangle before the name) or the mean (without triangle) of a factor between each pair of samples. Factors marked with ‘.Ann’ are annual means, while the remaining were measured in the sampling month. Livid circle under each factor name indicate the factor related to water (W), plant (P), soil properties (S), or temperature (T). Significance was expressed as ***p < 0.01; **p < 0.05; *p < 0.1 (see Source Data file for exact p values). Temp, temperature. Source data are provided as a Source Data file.
