Carnicero P., Kröll J., Schönswetter P. 2023: Homoploid hybrids are common but evolutionary dead ends, whereas polyploidy is not linked to hybridization in a group of Pyrenean saxifrages. Molecular Phylogenetics and Evolution, Volume 180. https://doi.org/10.1016/j.ympev.2023.107703

Highlights

  • Pervasive homoploid hybridization without evolutionary consequences.
  • Polyploidy occurs within S. moschata, unlinked from hybridization.
  • Autotetraploids are partly morphologically and ecologically differentiated.
  • S. pubescens and S. iratiana are separate species and no subspecies.
