So Young, So Rich: Habitat Shifts Combined With Trait Evolution Promoted Species Radiation in Senecio in the Andes

Popis výsledku v původním jazyce

The outstanding Andean biodiversity has been linked to the occurrence of evolutionary radiations that are common among high-elevation plant lineages. One of the most iconic examples is found in the species-rich genus Senecio, with an impressive variation in growth forms and habitat preference. Here, we use Hyb-Seq to overcome the lack of phylogenetic resolution found in previous studies with the aim of disentangling the processes shaping Senecio's hyper-diversity in the Andes, including the evolution of woodiness, growth form and habitat preference.nSenecio ser. Culcitium is a monophyletic lineage, likely of a Pleistocene origin. Hybridisation, possibly promoted by altitudinal range shifts during the Pleistocene climatic oscillations, played an important role in its evolution. We found evidence for several events of south-to-north migration from the puna on the Central Andes to the páramo on the Northern Andes. One of these migrations to the páramo resulted in a dramatic species diversification. Habitat changes from the páramo to the montane forest occurred multiple times and were associated with growth form shifts.nWith a net diversification rate of 2 species per million years, high-elevation Andean Senecio is among the fastest diversifying lineages documented so far in the region. Frequent shifts in woodiness, growth form, and habitat played a crucial role in the diversification of this lineage.
