Table 3. Results of the relationship between coral cover at Ningaloo Reef and explanatory variables using general linear mixed-effects model comparison based on Akaike’s information criterion (AICc) corrected for small sample sizes.
Model | df | –LL | AICc | wAICc | %DE |
Intercept only (cover ∼1) | 4 | −774.9794 | 1557.9587 | 0.0000 | 0.0000 |
Slope (year∼cover) | 23 | −747.6121 | 1541.2243 | 0.0000 | 3.5314 |
Habitat (year∼hab) | 27 | −736.8372 | 1527.6745 | 0.0000 | 4.9217 |
Area (year∼cover+area) | 24 | −753.02 | 1554.0400 | 0.0000 | 2.8335 |
Latitude (year∼cover+ lat) | 57 | −691.0784 | 1496.1568 | 0.9097 | 10.8262 |
All (year∼cover+area+hab+lat) | 62 | −688.3889 | 1500.7778 | 0.0903 | 11.1733 |
All models include the random effect ‘sampling site’. For each of the models contrasted, maximum log-likelihood (-LL), AICc, AIC weight (wAICc), and the % deviation explained (%DE) are shown..
