The importance of marginal population hotspots of cold-adapted species for research on climate change and conservation

Areas hosting hotspots of low-latitude marginal populations of coldadapted plant species could be key areas for understanding geographical attributes that result in refugia during climatic shifts as well as the conservation of genetic diversity in the face of climate change. Low-latitude populations...

Low-latitude populations of cold-adapted plants are important because they may harbour the combination of alleles that foster persistence in a warmer climate.

Rockies and Sierra Nevada both in California and Spain, Apennines, and the southern Scandes, maintain their hotspot status even with more stringent cut-off thresholds (>3 and >5 species per cell group).
