Data from: Mountain building, climate cooling and the richness of cold-adapted plants in the northern hemisphere
Aim The summits of mountain ranges at mid-latitude in the Northern Hemisphere and the Arctic share many ecological properties including comparable climate and similar floras. We hypothesise that the orogeny during the Oligocene-Miocene combined with global cooling allowed the origin and early divers...

Methods We mapped the cold climate in the Northern Hemisphere for most of the Cenozoic (60 Ma until present) based on paleoclimate proxies coupled with paleoelevations. We generated species distribution maps from occurrences and regional atlases for 5464 cold-adapted plant species from 756 genera occupying cold climates. We fitted a generalised linear model to evaluate the association between cold-adapted plant species richness and environmental as well as geographic variables. We performed a meta-analysis of studies, which inferred and dated the ancestral geographic origin of cold-adapted lineages using phylogenies. Results We found that the subalpine-alpine areas of the mid-latitude mountain ranges comprise higher cold-adapted plant species richness than the Palearctic and Nearctic polar regions. The topo-climatic reconstructions indicated that the cold climatic niche occurred first in mid-latitude mountain ranges (42-38 Ma), specifically in the Himalayan region, and only later in the Arctic (22-18 Ma). The meta-analysis of the dating of the origin of cold-adapted lineages indicated that most clades originated in central Asia between 39 and 7 Ma. Main conclusions Our results support the hypothesis that the orogeny and the progressive cooling in the Oligocene-Miocene generated cold climates in mid-latitude mountain ranges, before the appearance of cold climates in most of the Arctic. Early, cold mountainous regions likely allowed for the evolution and diversification of cold-adapted plant lineages followed by the subsequent colonisation of the Arctic. Our results are in line with Humboldt’s vision of integrating biological and geological context in order to better understand the processes underlying the origin of arctic-alpine plant assemblages.
