    Snippet: In these analyses, phylogeny is not a covariate, but incorporated into the error structure, and an additional phylogenetic correlation parameter (k; Pagel 1999) is estimated, to determine if phylogeny can explain variation unexplained by the model covariates. For bats, k, was 0 for the best models for number of viruses and degree (Table S3 and S6), indicating that phylogeny did not explain any additional variation. A likely explanation is that th.....
    Document: In these analyses, phylogeny is not a covariate, but incorporated into the error structure, and an additional phylogenetic correlation parameter (k; Pagel 1999) is estimated, to determine if phylogeny can explain variation unexplained by the model covariates. For bats, k, was 0 for the best models for number of viruses and degree (Table S3 and S6), indicating that phylogeny did not explain any additional variation. A likely explanation is that the best models included diet, which is strongly related to phylogeny. However, k for the best model for betweenness was 0.79 (Table S9 ), indicating that phylogeny explained additional variation.
