Abstract [en]
The most common and widespread alpine plants on ultramafic soils in Fennoscandia belong to the Cerastium alpinum complex (Caryophyllaceae). This complex consists of polyploid alpine plants, which show great morphological variation. Both hairy and glabrous morphotypes are found on ultramafic soils. To shed light on the evolution and the postglacial colonization of the C. alpinum complex, we have studied the genetic differentiation of populations on ultramafic soils in Fennoscandia. Thirteen populations in Norway, Sweden and Finland were analysed by starch gel enzyme electrophoresis. Preliminary results show that there is a genetic and geographical differentiation of populations on ultramafic soils, resulting in one eastern and one western group. This suggests that there were two independent postglacial colonization events of C. alpinum on ultramafic soils in Fennoscandia. The hairy and glabrous morphotypes are found both in the eastern and western population groups, suggesting that the morphotypes on ultramafic soils have a multiple origin.
