Table 5 Base and best-fit models of two responses species richness (SR) and species abundance (SC) with site and RPM complex treated as random effects. Selected models had the lowest corrected Akaike information value (AICc) and the lowest delta value (Δ)
Response variable | Type of model | Model | AICc | Δ |
|---|---|---|---|---|
SR | ZIGLMM (base model), Poisson distribution | SR ~ size + plant_com + RPM + canopy + elevation + age + (1|site) + (1|RPM) | 1107.6 | 36.99 |
ZIGLMM (best-fit model), Poisson distribution | SR ~ size + forest_com + + (1|site) + (1|RPM) | 1076 | 0 | |
SC | GLMM (base model), Gamma distribution | SC ~ size + plant_com + RPM + canopy + age + (1|site) + (1|RPM) | 2227.7 | 12.59 |
GLMM (best-fit model) | SC ~ RPM+ age+(1|site) + (1|RPM) | 2215.1 | 0 |
