Population Genetics of the Cave-dwelling Dusky Fruit Bat, Penthetor lucasi, Based on Four Populations in Malaysia

Population Genetics of the Cave-dwelling Dusky Fruit Bat, Penthetor lucasi, Based on Four Populations in Malaysia

The population genetics of P. lucasi was inferred using 1,061 base pairs (bp) of the Cytochrome b mitochondrial gene. A total of 77 individuals were classified a priori according to their localities, namely, Miri, Kuching, Sri Aman and Kelantan. Results showed that the populations of P. lucasi were...
