Table 1 Model building of the factors involved in the behavioural variables displayed by the three Podarcis species in the Y maze. SVL: snout-vent length, Loc: locality, d.f.: degrees of freedom, AIC: Akaike’s Information Criterion, ΔAICc: delta score computed as AICci – min AICc. Selected models are in bold

From: Correction to: Invasive Italian wall lizards outcompete native congeneric species in finding food in a Y‑maze
