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

Description: Plant trait variation can be the result of environmental variability, developmental instability, and plasticity, although it can also arise from previous selective pressures on fruit traits themselves or directly on their variation. We aimed to quantify fruit size and shape variability at within-pla...

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

Description: 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...

Seed predators exert selection on the subindividual variation of seed size

Description: Subindividual variation among repeated organs in plants constitutes an overlooked level of variation in phenotypic selection studies, despite being a major component of phenotypic variation. Animals that interact with plants could be selective agents on subindividual variation. This study examines s...

Selective Pressure along a Latitudinal Gradient Affects Subindividual Variation in Plants

Description: Individual plants produce repeated structures such as leaves, flowers or fruits, which, although belonging to the same genotype, are not phenotypically identical. Such subindividual variation reflects the potential of individual genotypes to vary with micro-environmental conditions. Furthermore, var...

Floral morphology and reproductive success in herkogamous Narcissus cyclamineus (Amaryllidaceae)

Description: We studied the variation on floral traits of Narcissus cyclamineus, a species endemic to the northwestern Iberian Peninsula. We analyzed the effect of different breeding systems and the degree of herkogamy and stigmatic exertion on female reproductive success. Results showed that, while variation on...

Flower color preferences of insects and livestock: effects on Gentiana lutea reproductive success

Description: Angiosperms diversification was primarily driven by pollinator agents, but non-pollinator agents also promoted floral evolution. Gentiana lutea shows pollinator driven flower color variation in NW Spain. We test whether insect herbivores and livestock, which frequently feed in G.lutea, play a role i...
