Distribution maps of the studied species across Europe. For each species (a, Pinus uncinata; b, Abies alba; c, Fagus sylvatica; d, Pinus sylvestris; e, Quercus robur; f, Quercus petraea) the green area represents the distribution of the species in Europe. The dots in the graph indicate the location of the northern (blue triangle), intermediate (black circle) and southern or rear-edge (red squares)
