From the north into the Himalayan–Hengduan Mountains: fossil‐calibrated phylogenetic and biogeographical inference in the arctic‐alpine genus Diapensia (Diapensiaceae)
Abstract Aim Many arctic species are believed to be descendants from ancestors that migrated northwards from high mountains during the formation of the modern arctic biome 2–3 million years ago (Ma). Here, we test whether this hypothesis is consistent with the biogeographical history of the arctic‐a...
