Several bioclimatic factors played a role in shaping the diversity of the ELF community. (a) Investigating the relationship between fungal species richness (Chao1) and isothermality (BIO3). (b) Analyzing the correlation of fungal species diversity (Shannon), mean temperature of warmest quarter (BIO5), max temperature of warmest month (BIO7), and temperature annual range (BIO10). The topmost distribution and scatter plots displayed the data distribution for each variable and Spearman correlation value between variables. The right-side stacked bar plot illustrated the semi-partial correlations of each variable. By performing multiple regression analysis with statistical significance and confirming multicollinearity with variance inflation factor calculation, we extracted climate data that are significantly associated with fungal diversity. *** p < 0.005, ** p < 0.01, * p < 0.05
