Summary of relationships among predictors (yellow rectangles) and dependent variables (grey ovals). Models were fit using phylogenetic generalized least squares regressions. Effect size is a standardized regression coefficient and is depicted by path width. We did not use phylogenetic path analyses, because that would lead to substantially reduced sample sizes. “Growth rate” is peak growth rate (U-Logistic curve) and it was not estimated for tail length (see Methods). “Latitude” is a geographic latitude, increasing away from the equator.
