We reconstructed the phylogenetic tree of the bat species investigated in this analysis using 15 sequences under the constraint of acknowledged taxonomic relationships (Figure 3 ). The constrained tree (2lnL = 6439.91045) did not differ significantly from the unconstrained tree (SH test: diff. lnL = 7.89267, Table 5 . Levels of phylogenetic signal in the variables investigated using the parameter K and the parameter lambda. Figure 4 . Partial relationship between viral richness and distribution fragmentation, assessed by a measure of distribution shape using (A) phylogenetic independent contrasts, or (B) raw values (and using residuals from the general regression modelling in Table 7) . doi:10.1371/journal.pone.0100172.g004 P = 0.126), and was thus considered as a reasonable depiction of bat phylogeny.
