- Numerator degrees of freedom (numDF) are constant across all models, while denominator degrees of freedom (denDF) change with the number of parameters in the model. Significance of F value of P < 0.001, <0.01, <0.05 and not significant are indicated by ***, **, * and n.s, respectively. Models were simplified manually until only significant effects remained (or effects marginal to interactions). Design variables were always included in the model, irrespective of significance. LUT and Explo refer to land-use type and exploratory region, respectively
