Topography explains the distribution of genetic diversity in one of the most fragile European hotspots

Aim To investigate factors that explain the spatial pattern of genetic diversity in three closely related species ( Linaria glacialis , Linaria nevadensis and Chaenorhinum glareosum ) endemic to a fragile high mountain ecosystem. Location The alpine belt of Sierra Nevada, Spain. Methods We analysed the spatial pattern of cpDNA diversity of the three species. To explain the distribution of genetic diversity, we investigated the effect of...
