It is demonstrated that herbicide resistance encompasses contrasting genetic routes, with polygenic NTSR evolving largely through selection on standing variation, offering broader insights into the evolutionary dynamics of rapid polygenic adaptation under novel anthropogenic selection.
Hybridization may have multiple impacts on speciation and adaptation. Yet the evidence of adaptive introgression events that have historically occurred between nonradiating or established species is still lacking. The oakleaf butterflies in the genus Kallima include multiple sympatric and incipient species with a kno...

Demographic processes such as colonization to new environments and gene flow fundamentally shape the genomic landscape, either facilitating or constraining the efficiency of selection by altering the balance between genetic diversity and adaptive responses. Although theoretical predictions suggest that the efficacy of...

Chromosomal rearrangements are hypothesized to facilitate speciation by suppressing recombination in locally adapted genomic regions, yet how they shape evolutionary rates during rapid divergence remains poorly understood. Here, we investigate the genomic architecture of two sister Carex (Cyperaceae) species on Réunion...

Defining the genetic basis of local adaptation is a key goal of evolutionary biology and crop improvement. Theory predicts that when selective pressures follow differences in the environment, a cline will be established. Clines can be exploited to uncover adaptive variation by association of alleles with the environmen...

Climate change is increasing drought and heat stress in European forests, raising concerns about the capacity of long-lived tree species to respond to rapidly changing environmental conditions. While local adaptation has been documented in many forest trees, it remains unclear whether newly established seedlings, which...

Speciation has classically been viewed as a process requiring complete reproductive isolation between species. However, genomic studies increasingly show that gene flow, the transfer of genetic material between species via hybridization, can promote adaptation and speciation by boosting genetic variation within lineage...
