Abstract

Resolving phylogenetic relationships within Vespertilionidae has been difficult, with large datasets (>100 taxa, >7 kilobases) resolving portions of the phylogeny, but leaving intertribal relationships within the Vespertilioninae unresolved. As a result, the evolutionary history of the most speciose chiropteran family is largely unknown. The presence of short internodes followed by long terminal branches relative to other chiropteran phylogenies suggests evolutionary rates of DNA substitution and lineage diversification may be inhibiting phylogenetic resolution. To test this hypothesis, we obtained sequences of the mtDNA 12s rRNA, tRNAVAL, and 16s rRNA as well as the nuclear exon RAG2, resulting in over 3 kilobases of digenomic DNA sequence data for representatives of all subfamilies and tribes within Vespertilionidae and Phyllostomidae, a family of bats that radiated at approximately the same time as Vespertilionidae. Analyses revealed substitution rates for Vespertilionidae were significantly higher than Phyllostomidae, with the majority of fast-evolving lineages found within Vespertilioninae. Cladogenesis analyses characterized the vespertilionid radiation as compressed toward the root, with a rapid initial diversification, while the phyllostomid diversification was much more gradual. We suggest ecological differences between tropical and temperate environments may have influenced diversification rates for Vespertilionidae and Phyllostomidae.
