Figure 4From: Species replacement along a linear coastal habitat: phylogeography and speciation in the red alga Mazzaella laminarioidesalong the south east pacificCOI Bayesian skyline plots for each haplogroup of M. laminarioides . Effective population size fluctuations throughout time are represented for the Northern, Center and Southern haplogroups. The solid line represents the median estimate and the grey area the 95% highest probability density. Abbreviations used: Ne = effective population size, T = time, BP: before present.Back to article page
