Abstract

Copper mine populations ofLychnis alpina are shown to be significantly more resistant to increased copper concentrations compared to populations on normal soils. Data obtained from isozyme polymorphism analysis revealed that although the copper populations display considerable variation, they have lower genetic variability than the populations from normal soils, both on a local and a global scale, thus indicating a slight founder effect. Copper ecotypes inL. alpina have originated independently. The results are similar to what recently have been reported in heavy metal tolerant populations ofArmeria maritima.
