Adaptive divergence is widely accepted as a contributor to speciation and the maintenance
of species integrity. However, the mechanisms leading to reproductive isolation, the genes …

Oak species show a wide variation in morphological and physiological characters, and
species boundaries between closely related species are often not clear-cut. Still, despite …

Introgression can be an important source of new alleles for adaption under rapidly changing
environments, perhaps even more important than standing variation. Though introgression …

The pace of tree microevolution during Anthropocene warming is largely unknown. We used
a retrospective approach to monitor genomic changes in oak trees since the Little Ice Age …

Loci considered to be under selection are generally avoided in attempts to infer past
demographic processes as they do not fit neutral model assumptions. However …

PREMISE OF THE STUDY: Introgression of adaptive alleles between hybridizing species is
likely an important mechanism to generate new genetic variation for adaptation to rapidly …

Background Hybridization and introgression are common phenomena among oak species.
These processes can be beneficial by introducing favorable genetic variants across species …

Abstract Background and Aims Hybridizing species such as oaks may provide a model to
study the role of selection in speciation with gene flow. Discrete species' identities and …

Understanding the effects of the demographic dynamics and environmental heterogeneity
on the genomic variation of forest species is important, not only for uncovering the …

Successful hybridisation and subsequent introgression lead to the transfer of genetic
material across species boundaries. In this process, species relative abundance can play a …
