19.08.2015 Our af1000rticle: Settling down of seasonal migrants promotes bird diversification., Proceedings. Biological Sciences / the Royal Society, 2014 (DOI: 10.3410/f.718361426.793508993), has been recommended in F1000Prime as being of special significance in its field by F1000 Faculty Member Ellen Ketterson. Here is here comment:

“This fascinating study examines the effect of migration on diversification in birds. Using phylogenies that included most extant bird species (9832 of 10,625) Rolland et al. found that seasonal migration increases diversification via sedentary populations arising from migratory populations, making it a leading factor of diversification in birds. Asymmetrical speciation, speciation of ancestral species into one sedentary and one migratory species, was more frequent in migratory species than sedentary. The authors suggest that the mobility of migratory species promotes the colonization of new areas and, if adapted to the new habitat, populations can become sedentary and diverge from the founding migratory species. The authors also found a lower extinction rate in migratory species compared to sedentary species. With higher diversification rates and lower extinction rates, migratory species have higher net diversification rates than sedentary species.”
