Cytotype coexistence leads to triploid hybrid production in a diploid-tetraploid contact zone of Chamerion angustifolium (Onagraceae).


UNLABELLED PREMISE OF THE STUDY Polyploids are often geographically segregated from their diploid progenitors, but the extent of sympatry and the consequences for reproductive isolation and coexistence are rarely quantified. • METHODS In this study, we document the distribution and co-occurrence of diploid and tetraploid Chamerion angustifolium among… (More)
