|I am broadly interested in the phylogeography of Southeast Asian animals, particularly that of flying foxes (Chiroptera: Pteropodidae: Pteropus). Pteropus is an ideal focal taxon for Southeast Asian biogeographic studies because it is: 1) found everywhere in the region; 2) species-rich with several widespread species and many island endemics; and 3) relatively easy to sample. The species richness of Pteropus, their unique distributions, and their distinct life histories make them well-suited to investigating mechanisms of divergence using genetic data among populations or between species. Vicariant and ecologically driven divergence each leave distinctive molecular signatures in descendent populations that can inform phylogeographic studies. I aim to use multilocus statistical phylogeographic methods to examine questions related to the biogeography of flying foxes such as: |
Ultimately, these findings related to population dynamics can be used for studying disease ecology of pathogens that flying foxes are a natural reservoir host for. Moreover, reconstructing a species tree for Pteropus will allow us to answer other questions related to biogeography and diversification of the genus in the geologically complex landscape of Southeast Asia.
- What is the evolutionary history of the genus Pteropus in Asia and what role did the region's complex geography play in diversification?
- Has vicariance or ecological divergence driven the diversification of Pteropus?
- What are the most common dispersal routes of widespread species and how frequent is dispersal? What are the population sizes and metapopulation structures of widespread Pteropus species?
I am currently funded on the NIH 1R21AI105050 grant: "Diversity and dispersal potential of bat-borne zoonotic viruses in the Indo-Australian Archipelago." This project is a novel collaboration between the Lohman Lab (CCNY), the Simmons Lab (AMNH) and the Dhanasekaran and Smith Labs (Duke-NUS Medical School, Singapore). This project is an extension of a collaboration I built while away on an NSF EAPSI in Singapore and of an existing collaboration between myself and Indonesian mammalogist Sigit Wiantoro (LIPI).
