Our study revealed high H-E and A(R) in all studied populations that were unconnected with population size, and the occurrence of unique alleles both in central as well as in marginal northernmost (Estonian) populations. Overall genetic structure reflected the geographical location of populations. Very weak population structure together with high historical migration at the distribution margin imply a past, more continuous occurrence of T. alpestre in the northernmost region. Recent bottlenecks, lowered seed production and lighter seeds in marginal populations point to the local suboptimal conditions and indicate the need to pay more attention to management to prevent loss of genotypes and maintain diverse populations in this region.
