description The Mariana flying fox ( Pteropus mariannus ) has suffered substantial decline in recent years. Taxonomic classification of P. mariannus has been inconsistent, with subspecies designations based mainly on geography and morphological variation within small sample sizes. In this study, we examine relationships of P. mariannus across two island groups in the western Pacific Ocean. Microsatellite data and mitochondrial sequences, from D-loop, cytochrome oxidase I, and cytochrome b, suggest that the population on the islands of Palau is genetically isolated from the populations in the Mariana Islands. Our data confirm that the bats of Palau should be considered a separate conservation unit from the bats of the Mariana Islands, supporting the current subspecies separation of these two populations. Our results also suggest that there is gene flow among islands within the Mariana archipelago and that the bats on these islands, currently classified as two subspecies, should be managed as a single conservation unit, although we refrain from suggesting taxonomic revisions until genetic and morphological data become available from geographically intermediate populations.
