The geographical and environmental determinants of genetic diversity for four alpine conifers of the European Alps.

abstract：:Diversification and speciation of terrestrial organisms are anticipated in oceanic islands such as Macaronesia, a group of Atlantic islands that have remained unconnected to continental landmasses. Hitherto, the diversification of marine organisms in oceanic islands, especially those with low vagility, has received li...
