  • The πWithin statistic signifies the average number of pairwise differences between two individuals sampled from the same population. The πBetween statistic denotes the average number of pairwise differences between two individuals sampled from different populations (Populations 1 and 2). “Pop 1” and “Pop 2” refer to Population 1 or 2 from columns 1 and 2, respectively. The “All Western Barred Owls” population is a combination of the “Western Barred Owls” and “Siskiyou Barred Owls” populations. The “Spotted Owls (pre-contact)” and “Spotted Owls (post)” populations indicate Strix occidentalis from populations not in contact or in contact with S. varia, respectively.
