Alpine plant biodiversity: why is it so high?

Bucknell University/University of California-Berkeley and Rancho Santa Ana Botanic Garden

Alpine plant communities exhibit a high number of species, possibly due to plants' ability to make extra copies of their genomes (a phenomenon called polyploidy). We are using alpine plants to investigate the role of polyploidy in influencing increases in species numbers. We aim to explore facets of adaptation of alpine plants to climate change through collections, DNA analyses, and greenhouse studies.
