Title

Importance of polyploidization for diversification of hyperdiverse Euphorbia subgen. Esula : polyploidy is positively correlated with increasing latitude, but negatively with elevation

Špela Pungaršek; Jasna Dolenc Koce; Božo Frajman Annals of Botany 2026. doi:10.1093/aob/mcag056

Other claims from this paper (8)

Observation Polyploidy frequency varied unevenly among lineages.
Observation Putative auto- and allopolyploids had similar incidence.
Association Life-cycle transitions primarily drove evolutionary genome-size down- and up-sizing.
Association Polyploidy contributed less to genome-size change than life-cycle transitions.
Association Annual species had smaller genome size than perennials.
Association Annual and perennial species had the same probability of polyploidy.
Association Polyploids were associated with higher latitudes.
Association Polyploids were associated with lower elevations.
