Genet age in marginal populations of two clonal Carex species in the Siberian Arctic
During a Swedish‐Russian expedition to northern Siberia 1994, we sampled two marginal populations of two Carex species at two high arctic sites ( C, stans Drej. on Faddeyevsky Island and C. ensifolia V. Krecz ssp. arctisibirica Jurtz. at north‐eastern Taymyr Peninsula), both north of previously docu...
