  1. Binomial models for forest dependent and non-forest species were conducted and full models (glm, R package ‘stats’; glme, R packages ‘lme4’) after eliminating multicollinearity (vif, R package ‘car’) are presented; Generalized Linear Model (GLM): variables included: SVL females, sexual dimorphism, clutch size class, larval habitat; removed due to co-linearity: adult habitat, reproductive mode, and egg deposition site; Generalized Linear Mixed Model (GLMM): range size and elevation range as fixed and region of continent random factors (no co-linearity among explaining variables); significant effects are in italics; D forest dependent species (n = 33), NR non-responding species (n = 83), I forest independent species (n = 19)
