Whereas it is generally agreed that the Neotropical bat family Mormoopidae, as well as the two mormoopid genera (Mormoops and Pteronotus) are each monophyletic, relationships among the six extant species of Pteronotus remain unresolved. The purpose of this study was to evaluate phylogenetic relationships within Pteronotus using DNA sequence data from the mitochondrial ribosomal and cytochrome b genes and the nuclear Recombination Activating Gene-2 based on likelihood inferential techniques (maximum likelihood and Bayesian phylogenetics). Results of this study present, for the first time, a fully resolved and strongly supported phylogeny for all relationships within Pteronotus. These data strongly support: sister-group relationships between davyi and gymnonotus (subgenus pteronotus), between macleayii and quadridens (subgenus chilonycteris), and between the subgenera pteronotus and chilonycteris. Pteronotus personatus is sister to this clade and P. parnellii is the most basal lineage of Pteronotus. Although this is the first study to provide a fullyresolved and strongly supported hypothesis for the phylogenetic relationships among species of Pteronotus, future work must focus on phylogeographic surveys within each species because previous studies have suggested that parnellii and personatus may contain undescribed species.

Parks and other protected areas in tropical forests often include secondary forest, cropland, and pasture. Documentation of the impact of such anthropogenic disturbance is essential for effective management. We re-sampled bats within Mount Isarog Natural Park (MINP), a protected area in southeastern Luzon, Philippines, seventeen years after a survey in old- and second-growth forest and in agro-pastoral areas was conducted in 1988. By employing harp traps and a tunnel trap, in addition to mist nets as used in the earlier study, we aimed to document species previously undetected by mist netting alone. We documented 26 bat species, seven of which were captured exclusively in harp traps, and two that were only captured in a tunnel trap. This survey resulted in nine new records of bat species for MINP, bringing the total number to 30. We did not recapture four species documented in 1988, all of which were noted in that study as uncommon. Nineteen species were captured in agro-pastoral areas on the south slope, including two Hipposideros spp. not captured at the forested sites.
