  • Counts consistently exceed those obtained by randomizing the data (Table S1). “Species” is number of species analyzed. “Prior” is average extinction probability based on a first-pass analysis of the data. “Posterior” is average extinction probability based on a reanalysis using the computed prior. “Extinct” is sum of extinction probabilities. “CI” is bootstrapped 95% confidence interval.
