High morphological diversity in remote island populations of the peat moss Sphagnum palustre: glacial refugium, adaptive radiation or just plasticity?

Many islands are characterized by high biological diversity, and both adaptive and non-adaptive factors have been found to contribute to island richness. Here we study extensive color morph variability in the allopolyploid peat moss Sphagnum palustre on the Azores Islands. By comparing genetic diver...
