The first large-scale historical biogeographical study of spikemosses reveals surprising patterns
2016 (English)Conference paper, Abstract (Other academic)
Selaginellaceae, spikemosses, is a lycophyte family with a history dating back some 350 million years. Selaginella selaginoides (dvärglummer) is the single Swedish species; the rest of the ca. 750 species are mainly found in the tropics. Recently, we presented a large-scale phylogeny of Selaginellaceae and with that as a framework, we have studied the historical biogeography of the group. Besides its old age, Selaginellaceae is an interesting study system due to its heterospory. Both small microspores and large megaspores are involved in reproduction and the "large" size of the megaspores (0.2–1.2 mm) is thought to have a negative effect on dispersal. The results of our historical biogeographical analyses are surprising and change our view on which plants that disperse over long distances.
