Fig. 4From: A combination of long term fragmentation and glacial persistence drove the evolutionary history of the Italian wall lizard Podarcis siculus Extended Bayesian skyline plots inferred with BEAST, illustrating effective population sizes (Ne) through time. The grey lines represents the median population size, and the colored lines represent 95% higher posterior probability of (a) T clade, (b) A2 clade, (c) S3 clade and (d) S1 clade. The grey rectangles corresponds to the Würm, Riss and Mindel glacial periods while dashed lines indicate approximately the last glacial maximumBack to article page
