Summary of the model selection statistics for the analysis that evaluated the relationship between paternal care and the mean and the variance of body condition proxies (controlled by structural body size) of Iporangaia males.

NOTE. - Models are ranked by increasing order of their bias-corrected modified Akaike Information Criterion (AICc). The best models in each stage are indicated in bold. ΔAICc is the difference between the AICc value of model i and the AICc value of the most parsimonious model; K is the number of estimable parameters in the model I; Weight is the Akaike weight of model I; DSL is the males' dorsal scute length (mm); V is the males' body volume (mm3); caring period is the estimated time males have already invested in parental activities (see text for methodological details); and parental state is the classification of males into the caring or non-caring categories.
