Clonal growth forms in Arctic plants and their habitat preferences: a study from Petuniabukta, Spitsbergen
Abstract The ability to grow clonally is generally considered important for plants in Arctic regions but analyses of clonal characteristics are lacking for entire plant communities. To fill this gap, we assessed the clonal growth of 78 plant species in the Petuniabukta region, central Spitsbergen (S...
