Results of linear models testing the effect of tree branch length to the root extracted from a treemix population phylogeny on the load (πN/πS,panel A) and different metrics of selection efficacy B: relationship between ωNA and tree branch length; C: relationship between ωA and tree branch length; D: relationship between α and tree branch length. See text for a definition of each metrics). Sample sites are coloured by region. The blue line represents the value of the regression line. In all panels each point represents a sampling site and is coloured according to the region in which it was sampled. Displayed is the adjusted R2 along with its p-value. (TIF)
