The regression analysis was made only with the bromeliad variables retained as the best model based on the Akaike Information Criterion. The variations in the values of spider body size and flatness were partitioned into ecological (EC), niche conservatism (NCC) and phylogenetic components (PC; see text for details). The R² _adj value presents the explained variation of the best model for each component regressed against bromeliad morphological variables. Thus, the repeated R² _adj value does not represent the explained variation of each variable.
