Data from: AFLP markers reveal high clonal diversity and extreme longevity in four arctic-alpine key species
We investigated the clonal diversity, genet size structure and genet longevity in populations of four arctic-alpine plants (Carex curvula, Dryas octopetala, Salix herbacea and Vaccinium uliginosum) in order to evaluate their persistence under past climatic oscillations and their potential resistance...

The presence of genets in all size classes and the dominance of presumably young individuals suggest continuous recruitment over time, a precondition for adaptation to changing environmental conditions.
