Threat status among amphibians declines with increasing body mass, or with increasing range size. Scatterplots show proportions of amphibian species classed as threatened according to IUCN categorization against (A) midpoints of binned log10(Body mass) classes and (B) midpoints of binned log10(Range size) classes. Fitted lines describe trends in probability of being threatened, derived from single-predictor phylogenetic logistic regressions with binary error structure. Point sizes are proportional to the log10 of sample size in each bin.
