Table 5 Twelve candidate linear mixed-effects models used to analyse shear forces exerted by the three Oedura geckos, O. castelnaui, O. monilis and O. coggeri
From: Geckos cling best to, and prefer to use, rough surfaces
Model | Response variable | Random effect | Fixed effects |

4 | log(shear force) | gecko ID | Substrate + Species + log(mass) + log(toepad area) |
5 | log(shear force) | gecko ID | Substrate + Species + log(mass) |
6 | log(shear force) | gecko ID | Substrate + Species + log (toepad area) |
