Table 1 Linear regression relating predicted changes in range size of species as well as in changes in the frequency of the warm-adapted haplotype to potential drivers

  1. Range size changes were measured as log(range size in 2080/range size in 2000) and haplotype frequency changes as log(percentage of warm-adapted haplotypes in 2080/percentage of warm-adapted haplotypes in 2000). Values shown are for the European Alps/an artificial test grid representing a mountain slope under moderate/severe climate change (CC), respectively. P values are derived via F-statistics.
