Abstract

We used the random amplified polymorphic DNA (RAPD) technique to decipher the genetic structure of the Bank Myna (Acridotheres ginginisnus) in Pakistan. The samples were collected from four cities namely: Dera Ghazi Khan, Jahanian, Khanewal and Gujranwala. The analysis showed a high genetic diversity at species level (H = 0.318, S = 0.467) but low levels at population levels (H = 0.047, S = 0.069 to H = 0.195, S = 0.283). The four populations analyzed were genetically distant from each other and hinted the effect of urbanization role in isolating the urban dwelling species. The genetic distances between populations ranged from D = 0.2403 to D = 0.3419 and the similarity coefficient showed low range from 0.66 to 0.70. This study will help in future conservation plans and also help the understanding of the role of urbanization on fragmentation of species’ natural distribution and dispersal mechanism.


Key words: Acridotheres ginginisnus, Bank Myna, random amplified polymorphic DNA (RAPD), genetic structure.
