Figure 7From: Historical biogeography of the land snail Cornu aspersum: a new scenario inferred from haplotype distribution in the Western Mediterranean basinBayesian skyline plots showing the historical demographic trends for both B and C lineages detected for cyt b (a and b) and 16S RNA (c and d) sequences. Along the y-axis is the expressed population size estimated in units of N e μ (N e : effective population size, μ: mutation rate per haplotype per generation). Solid lines are median estimates whereas shaded areas represent confidence intervals.Back to article page
