Intra-specific variation of fruit size and shape in Corema album (Ericaceae) along a latitudinal gradient: from fruits to populations

Sampling procedures: In September 1997, we haphazardly selected 15 fruit-bearing Corema females in each population. Minimum distance among selected plants was 5 m, covering an approximately along-seaside transect of more than 200 m. We collected 30 ripe fruits from each of the plants, one by one and from the whole canopy of the plant, ensuring we sampled fruits along the entire perimeter of the plant and at all possible heights. All fruits were measured in the field or few hours after collecting them. In September 1998, we repeated the same sampling procedure on 15 newly selected females per population.
