  1. All measures of parasite taxonomic richness and traits show significant phylogenetic signal. Measurements of parasite taxonomic richness are residuals from the regression of Google Scholar citation count against the measure of parasite richness. Significance of the likelihood ratio tests (LRT) was determined using the Chi-Squared distribution with 1 degree of freedom.
