Table 1 Results of phylogenetic generalized least-squares (PGLSs) models explaining the variation in genome size in squamates as a function of microhabitat, parity mode and bioclimatic variables (PC1, PC2) and their interaction. The number of parameters (K), corrected Akaike’s information criterion (AICc), difference in AICc with respect to the model with the highest support (∆AICc) and Akaike’s weight (wi) are given for each model. Absolute value of median latitudes (Lat) and Pagel’s lambda (λ = 0/1) were included as covariates in all models. Asterisks indicate models with P < 0.05 after a full-null model comparison
