Genetic Variability and its Geographical Distribution in the Widely Disjunct Cavernularia Hultenii
Abstract The fruticose lichen Cavernularia hultenii exhibits a strongly disjunct distribution between north-western North America, Newfoundland and north-western Europe. An investigation of its population structure, based on nuclear ITS and IGS DNA sequences, shows that western North America has a h...
