Table 2. Design and results of the four Generalized Linear Mixed Models performed to relate δ 13C (response variables) with food availability and the level of humanization (explanatory variables).
Model | Response variable | Explanatory variables | Estimate | SE | AICc | AICc null | P Value |
---|---|---|---|---|---|---|---|
1 | δ 13C | Landfill proximity | -6.31E-05 | 3.57E-05 | 104.31 | 104.60 | 0.0928 |
2 | δ 13C | Extensive livestock | -4.45E-05 | 7.10E-05 | 106.74 | 104.60 | 0.5336 |
3 | δ 13C | Urban areas | 0.25 | 0.06 | 96.10 | 104.60 | 0.0009 |
4 | δ 13C | Rural areas | -0.06 | 0.01 | 93.13 | 104.60 | 0.0002 |
There are indicated parameter estimates and standard errors (SE), AICc of each model, AICc of null model and also P Value obtained with the ANOVA performed between null and full model.
