ADAPTATION IN TUNDRA PLANTS EXAMPLIFIED BY TRANSPLANTATION STUDIES AT TWO LATITUDES (17th Symposium on Polar Biology)
Transplantation studies between Spitsbergen (78° 55' N) and the Dovre mountains in southern Norway (62° 14' N, ca. 1100 m a.s.l.) are carried out on three species (Carex rupestris, Luzula confusa and Polygonum viviparum), naturally growing in both ecosystems. Growth of the first two specie...
