Testing which axes of species differentiation underlie covariance of phylogeographic similarity among montane sedge species
Richard G.J. Hodel, Robert Massatti, Sasha G.D. Bishop, L. Lacey Knowles
2021, Molecular Ecology (75) 349-364
Co‐distributed species may exhibit similar phylogeographic patterns due to shared environmental factors or discordant patterns attributed to the influence of species‐specific traits. Although either concordant or discordant patterns could occur due to chance, stark differences in key traits (e.g., dispersal ability) may readily explain differences between species. Multiple species’ attributes...
