Marphological variation in the dusky fruit bat, penthetor lucasi, in Sarawak, Malaysia

Morphological analysis of 70 adult individuals of the dusky fruit bat, Penthetor lucasi, was performed using 15 external characters and 18 craniodental characters. Multiple regression and discriminant function analysis (DFA) were applied to test the effects of sex, location and interaction betwee...
