Diferenciación de hábitats en las aquilegias ibéricasimplicaciones en la radiación adaptativa del género

Abstract

The genus Aquilegia in North America has become an example of speciation and diversification, both by the variety of habitats they occupy and the variability in floral traits associated with different pollination syndromes. However, despite the lower diversity of potential pollinators that exists in Eurasia, the genus Aquilegia has a similar numbers of taxa in both continents, being most variable in vegetative than in floral traits. This work tries to answer the question: What has promoted niche differentiation and habitat divergence between different taxa of Iberian columbines? In general, our results obtained seem to confirm our hypothesis that contrary to what happened in North America, in the case of the Iberian columbines was specialization in habitat mediated by vegetative and eco-physiological traits, and no pollinator specialization, the main power of radiation in Iberian columbines.
