Different measures were calculated to describe clade stability: posterior probability, bootstrap value (BS), decay index (DI), Bayesian cluster recognition (GMYC) and branch length. Further, trophic level of the bats was also considered (Figure 3). Decay indices were obtained with TreeRot.v3 [117] in combination with the phylogenetic software PAUP 4.0 beta [89]. A decay index greater than ten is considered as strong support for a specific node. Automated cluster recognition via the "Generalized Mixed Yule-Coalescent" (GMYC) approach with multiple threshold extension was used [118–120]. Branches longer than the mean branch length (0.03 substitutions per position) are considered as long. Congruence indices were calculated by the number of useable support measures for a specific node divided by the number of cases in which there was high support.
