allopatric

“The scientists first played the birds two unfamiliar recorded sounds. One was the alarm cry of an allopatric chestnut-rumped thornbill, a bird not native to Australia. The other was a computer-generated bird sound dubbed ‘buzz’.” Christina Larson; Birds Learn Another ‘Language’ by Eavesdropping on Neighbors; Sunday Gazette-Mail (West Virginia) Aug 5, 2018. “Allopatric speciation is the most commonly accepted mode of speciation; it requires geographic separation and considerable time for populations of one species to become adapted to different environments and evolve mechanisms that prevent mating.” Jeff Mitton; Treehoppers’ Environments Are Defined by Their Host Species; The Daily Camera (Boulder, Colorado); Jul 27, 2017.
