Arctic-alpine biota occupy enormous areas in the Arctic and the northern hemisphere mountain ranges, and have undergone major range shifts during their comparatively short history. The origins of individual arctic-alpine species remain largely unknown. In the case of the Purple saxifrage, Saxifraga oppositifolia, an important model for arctic-alpine plants, phylogeographic studies have remained inconclusive about early stages of the species’ spatiotemporal diversification, but have provided evidence for long-range colonization out of a presumed Beringian origin to cover today's circumpolar range. . We re-evaluated the species’ large-scale range dynamics based on a geographically extended sampling including crucial areas such as Central Asia and the (south-)eastern European mountain ranges and employing up-to-date phylogeographic analyses of a plastid sequence and a more restricted AFLP data set. In accordance with previous studies, we detected two major plastid DNA lineages also reflected in AFLP divergence, ... : Results Diffusion ModelRange connectivity (Bayes Factors) and ancestral location probabilities among nine discrete geographical regions in Saxifraga oppositifolia inferred using reversible and non-reversible models of geographic diffusion of plastid DNA sequencesResultsDiffusionModelSaxOpp.txtAFLP MatrixAFLP data matrix (excluding not repeatable, monomorphic and single fragments) with individuals in rows and markers in columns.
