Where do macaronesian bryophytes come from?

Bryophytes exhibit efficient long-distance dispersal capacities, ‘all-purpose’ genotypes, low levels of endemism and limited biotic interactions. Their community structure and composition are therefore expected to display little differences with continental sources. However, endemic species show different patterns compared to non-endemic: the former have affinities with neotropical clades while the latter are almost the same as in Europe. To test this hypothesis, we identify, based on analyses of floristic similarities, coalescence phylogeographic analyses of non-endemic species, and phylogenies of endemic species, which continental floras are and have been the most likely sources for the Macaronesian flora.
