Tracing Scots Pine Expansion in Europe Using Patterns of Rare Alleles.

ABSTRACT: Past climatic oscillations have likely played a key role in the evolution of all tree species in Europe, by causing alternating phases of range expansions and population declines. Nevertheless, tree species display remarkable variation in terms of spatial differentiation and levels of genetic diversity, suggesting that other factors have played an important part. Among wind-pollinated trees, Pinus sylvestris displays an extremely low level of genetic structure over most of its distribution, but little is known about how this pattern has emerged. To better understand the processes that shaped this pattern of genetic diversity in P. sylvestris, we analyzed 11,020 SNPs from the nuclear and organellar genomes, sequenced from 185 trees across 20 populations from Europe, including
