Results of likelihood-ratio analysis of deviance of marginal mixed models using generalized least square with threatened species richness as a dependent variable
| Df | AIC | LRT | P value | |
|---|---|---|---|---|
| (Full model) | − 50.202 | |||
| Area | 1 | − 44.958 | 7.244 | < 0.01 |
| Null model (simulated range) | 1 | − 51.967 | 0.235 | 0.627 |
| Elevation | 1 | − 48.772 | 3.430 | 0.063 |
| Empirical range: population density | 1 | − 48.078 | 4.124 | 0.042 |
Likelihood-ratio analysis tested whether the deviance of the full model significantly increases after each explanatory variable was excluded from the model. The denominator Df = 28
