Phylogenetic dispersion of parasite assemblages among individual host species
Dispersion in parasite phylogenetic distances for host species carrying ≥3 parasites. Numbers in parentheses indicate the number of parasites observed infecting each host species. Observed and expected parasite distances were generated from 10 000 iterations, using a randomly sampled parasite phylogeny in each iteration. Negative differentials indicate phylogenetically clustered parasites (more closely related than expected by chance) while positive differentials indicate overdispersed parasites (more distantly related than expected). Presented are quantiles of parasite distances ranging from zero (nearest taxon distance; NTD) to 1 (mean pairwise distance; MPD). Boxplots show differential medians (lines within boxes) as well as 25% and 75% quartiles (hinges). Asterisks (*) indicate significant differences from 0.
