Amphibians and reptiles from the Mt. Hamiguitan Range of eastern Mindanao Island, Philippines: new distribution records

摘要

Despite extensive surveys conducted in the past, many remote areas in the Philippines remain unexplored and many species are unknown to science. The Mount Hamiguitan Range (MHR) is among these areas, containing large remaining forests tracts. In this study, we report new records of amphibians and reptiles from MHR and propose removing two species from the previously listed species from this mountain range. We used standardized techniques to sample populations of amphibians and reptiles in fragmented forests of Mt. Hamiguitan. Our survey resulted in 16 new records of species (four frogs, three lizards and nine snakes). Combining our results with previous studies, the known species diversity from the MHR is now increased to a total of 61 taxa. Our results highlight the underestimated diversity of herpetofauna of Mt. Hamiguitan, and we discuss the importance of repeated surveys for determining species occurrences and assessing their conservation status.
