In contrast, the central west and east coast region showed unexpected genetic homogeneity.
Some frog species use roads as activity corridors, including the Cane Toad, Bufo marinus (Seabrook and Dettmann, 1996), and Natterjack Toad, Bufo calamita (Stevens et al. 2006). Fejevarya limnocharis is generally abundant in human habitation and this may increase the opportunity for the frog to be transported accidentally or deliberately into new areas (Toda et al. 1997).
Thus, it seems plausible that migration had occurred between the central west and east coast of Peninsular Malaysia via the East-West Highway and colonized new populations, thus reducing their genetic differentiation.
This is in tandem with the high capability of dispersal possessed
by this species.
