Report on the genetic characterization

The genetic analysis with the specific molecular markers identified for Calendula maritima allowed us to distinguish pure populations from populations affected by hybridization with the congeneric species Calendula fulgida. Based on genetic purity, degree of intra-population diversity, consistency of population and health status, we selected among the purest populations the…

Mapping of the populations of Calendula maritima

After an accurate exploration of the whole coastline between the nature reserves ‘Foce del fiume Belice’ and ‘Zingaro’, a 1:2000 scale map of all extant populations of Calendula maritima has been carried out. We mapped 15 distinct populations, growing between the nature reserves ‘Isole dello Stagnone di Marsala’ and ‘Monte…
