Special Issue: Hybridisation, invasion and adaptation: the evolutionary dynamics of polyploidy in changing environments
This special issue is focused on how polyploidy and hybridization affect the ability of organisms to adapt to novel or changing environments. By combining papers describing classic cases of invasions dominated by allopolyploids, methodological challenges of working with polyploid and hybrid genomes, physiological consequences of polyploidy, and application of the latest genomic advances to investigating the evolutionary dynamics of polyploid genomes, a central purpose is to highlight the new insights that can arise from readdressing old questions in ecology and evolution with new tools. Although more data are needed, results suggest that genome duplication or combination could play a creative evolutionary role in changing environments.
