Further work should include morphological studies of these species to see if there are morphological differences between genetic groups. This can give an indication of individuals in the Pacific region and the ones in the Atlantic region should be treated as different taxa/species. This is important to know in relation to potential conservation. The populations of Sphagnum magellanicum in South America are genetically different from the ones in the Northern Hemisphere. This indicates that dispersal between the hemispheres are rare. In addition to molecular studies on peatmosses, I have compared refugial areas and colonization routes in Europe after the last glacial maximum for bryophytes. This is a review paper where already published data have been compared to see if there are some general trends among bryophytes. There are several species that show the same trends, and these patterns are also often found among other organism groups.
