The spatial modelling of high-latitude plant richness and refugia in a changing environment
Arctic-alpine regions are facing notable climatic changes. Improved understanding is needed of how these changes cascade into species distributions and what they might mean for the Arctic-alpine realm. These high-latitudes are expected to be susceptible to change. This vulnerability highlights the …
