| incipient speciation with gene flow on a continental island: species delimitation of the hainan hwamei (leucodioptron canorum owstoni, passeriformes, aves). | because of their isolation, continental islands (e.g., madagascar) are often thought of as ideal systems to study allopatric speciation. however, many such islands have been connected intermittently to their neighboring continent during recent periods of glaciation, which may cause frequent contact between the diverging populations on the island and continent. as a result, the speciation processes on continental islands may not meet the prerequisites for strictly allopatric speciation. we used m ... | 2016 | 27233437 |
