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...

| description |
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
between individuals in the study, and to determine and identify characters which are efficient in
differentiating individuals among populations, respectively. Most characters were significantly affected by
sex, locality and their interactions. Thus, separate analyses were done for both sexes. The fourth digit
metacarpal length (D4MCL) and bulla length (BL) of males, and the hind foot (HF) and dental length (DL)
of females, were suggested as the best predictors for the external and craniodental characters, respectively,
in differentiating P. lucasi from different localities. These findings establish the morphological
morphological variation between three geographically separate populations of P. lucasi within Sarawak. It
is suggested that different ecological forces between populations, such as breeding, foraging behaviour,
crowding effects and resource availability, could have been the moulding factors behind the observed
morphological variations in the different P. lucasi populations. |
