PIC analysis was conducted for each ecological category with ecology treated as a binary state. For instances where species had ambiguous or multiple ecological states, separate analyses were run with the taxa in question coded both possible ways to determine the influence of the specific coding state for those taxa on the overall results. Saprotroph 1, Cryptococcus neoformans and Aspergillus spp. are coded as non-saprotrophic; Saprotroph 2,= C. neoformans and Aspergillus spp. are coded as saprotrophic; Animal path.1, C. neoformans, Aspergillus spp., and Neosartorya fisheri are coded as animal pathogens; Animal path. 2, C. neoformans, Aspergillus spp., and Neosartorya fisheri are coded as non-animal pathogens. MnConAll, average magnitude of independent contrast. SDConAll, standard deviation of independent contrasts, N, number of contrasts. Asterisk (*) symbols indicate P values less than 0.05, which are considered statistically significant.
