Variation in Silene vulgaris and S. uniflora (Caryophyllaceae): genetic diversity, gene flow and habitat selection
Genetic and morphometric variation was studies in the three closely-related taxa Silene vulgaris (a widespread weed), S. uniflora ssp. uniflora (restricted to coastal habitats) and S. uniflora ssp. petraea (endemic to Sweden and confined to open limestone habitats). The majority of alleles at the investigated allozyme loci are common to the three taxa, but the taxa show significant differences in
