2. Centaurea corymbosa, a cliff-dwelling species tottering on the brink of extinction: A demographic and genetic study
Centaurea corymbosa (Asteraceae) is endemic to a small area (≤3 km2), and <500 individuals reproduce in any given year. Nevertheless, enzyme polymorphism was found within and among the six local extant populations, the most distant at 2.3 km. Levels of gene flow among populations and seed and pollen dispersal data indicated very low dispersal capacity
