ResumenWe aimed at quantifying fruit size and shape variability of Corema album at within-plant, among-plant, among-population and among-year levels. For two years, we measured fruit size and shape along the geographic range along Atlantic coast of Iberian Peninsula. Most variance concentrated on within- and among-individual levels for size, showing higher values for among-individual variation in fruit shape. While fruit size retained important variation among populations, this source of variance was negligible for fruit shape. This difference could arise from contrasting mechanical or developmental constraints. Despite the marked climatic differences along the latitudinal range of the species, latitude did not affect the ratio of within- to among- plant variation.
DescripciónSampling 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.
