Table 1. Comparison of linear mixed-effect model fitted to the data on beetle Shannon diversity across 3 regions in Yunnan province, SW China. AICc means Akaike Information Criteria (Corrected). Delta means AICc Score differences. Weight refer to Akaike weights. Models with delta< 2 were presented and the top ranking model was the best. Conditional R2 represents the variance explained by both fixed and random effects (total R2), and marginal R2 refers to the variance explained by fixed effects only (fixed R2). The difference between these two components gives the R2 of the random effect (random R2).The full model was: BeeShannon_stdz ~ PlaPD_stdz + PlaChao1_stdz + PlaSimpson_stdz + PlaShannon_stdz + ELE_stdz + AMT_stdz + ATR_stdz + AMH_stdz + AHR_stdz + MTWM_stdz + MTCM_stdz + Latitude_stdz + (1|SiteName).
