The structure of allozyme variation in Silene nutans (Caryophyllaceae) in Denmark and in north-western Europe
We used allozymes to investigate the structure of genetic variation in populations of the perennial herb Silene nutans at local (Denmark), regional (Nordic area) and wide (over a 19° latitudinal gradient) geographic scales in north-western Europe. New data from Denmark were combined with data from p...
