MSVAR results: population size change.

A) ratio of current and ancestral population sizes (r = N₀/N₁) where r = 1 signifies population stability, r<1 decline, and r>1 expansion. 4B–D) Posterior distributions of the current (N₀) and ancestral (N₁) effective population size using both the exponential (thick lines) and linear (thin lines) models: B) northwestern-historical, C) southern Sierra Nevada-contemporary, and D) southern Sierra Nevada-historical. The dotted line shows the prior distribution for N₀ and N₁.
