چکیده انگلیسی
Aquilegia paui is a narrow endemic species from the north-eastern Iberian Peninsula. It has a reduced number of populations in the limestone mountain massif of Els Ports. Genetic diversity was evaluated through allozyme electrophoresis in this rare columbine, together with its widespread congener Aquilegia vulgaris. Low levels of genetic diversity were detected in both taxa, especially for A. paui. Genetic identity between the two columbines was particularly high (I = 0.990), and the allele pool of A. paui is a subset of that of its widespread congener (with the exception of a low-frequency allele that was only detected in one population of A. paui). A. paui may have recently evolved from nearby populations of A. vulgaris. Speciation of this taxon, which may still be ongoing, seems to be driven by ecological differentiation, as generally occurred for the European columbines as well as in many Mediterranean endemic species.
