Phenotypic variation at different spatial scales in relation to environment in two circumpolar bryophyte species
Morphology, physiology and biomass in two widespread bryophyte species, Hylocomium splendens and Racomitrium lanuginosum, were studied to examine the extent to which different species exhibit similar phenotypic variation patterns within and across regions. Analyses of nine morphological variables, c...

Morphology, physiology and biomass in two widespread bryophyte species, Hylocomium splendens and Racomitrium lanuginosum, were studied to examine the extent to which different species exhibit similar phenotypic variation patterns within and across regions.
