3. Social environment use	3	95.3	1.51	0.13	0.11
4. Exploratory behaviour in the pool	3	95.7	1.84	0.11	0.11
5. Habitat use	3	95.7	1.85	0.11	0.11
6. Condition × habitat use	5	95.9	2.07	0.10	0.18
7. Condition × social environment use	5	97.8	4.00	0.04	0.13

Models 6 and 7 include both the main effects and the interaction term between the two factors. K is the number of parameters estimated. QAICc is a smaller-is-better measure of goodness of fit. Delta (Δ) is the difference between the ‘best’ model with the lowest QAICc and all other models. Akaike’s weight (w) is the relative probabilities of each model given the data. R² is the conditional R² that shows the variance explained by fixed and random effects.
