Population histories of Tarim red deer (TRD_Y) and Tule elk (TE_S) populations. a PSMC analysis inferring variation in Ne over the last 106 years for the Tarim red deer and Tule elk populations. Generation time (g) = 6.3 years, and neutral mutation rate per generation (μ) = 1.5 × 10 − 8. b ∂a∂i analysis showing effective population sizes for the ancestral population and the Tarim red deer and Tule elk populations from ~ 1.17 × 10 7 years ago to the present. The average number of migrants per year between the two populations in each time interval is indicated by the labeled arrows
