Bayesian skyline plot. Bayesian skyline plot depicting the historical demography of the Northeastern (a) and Southeastern (b) European populations of Mustela lutreola based on mt haplotype data. The y-axis is equal to Ne τ, where Ne represents the effective population size and τ the generation time in years. The x-axis represents units of time before the present in thousands of years (Kyr). The thick solid line represents the median estimated Ne, and the coloured area shows the 95 % HPD limits of Ne τ. The Last Glacial Maximum (LGM, 22–18 Kyr) and Younger Dryas interstadial (YD, 12.8–11.5 Kyr) are also indicated
