Genetic diversity of alpine Dryas octopetala populations at their southern distribution limit in Europe
The arctic–alpine species Dryas octopetala has its southernmost European distribution in the northern part of Greece, where it forms isolated populations in three mountainous regions: Falakron, Tzena and Orvilos. This study aimed at estimating the intrapopulation genetic diversity and the overall ge...
