Variation in structural gender in the hermaphrodite Helleborus foetidus (Ranunculaceae): within- and among-population patterns

Description: In hermaphrodite plants, variations in structural gender (defined as the ratio between male and female gametes) may occur at different levels (among flowers, plants, and populations). In this study, we investigated variation in four traits influencing structural gender (number of carpels, ovules per...

Geographical variation in autonomous self-polliantion levels unrelated to pollnator service im Jelleborus foetidus (Ranunculaceae)

Description: Autonomous self-pollination may be considered as a mechanism enhancing plant reproductive success when plant access to pollen sources may limit seed production. We have studied the relationship between geographical patterns of variation in pollinator service to Helleborus foetidus and self-pollinati...

Plant Traits, Environmental Factors, and Pollinator Visitation in Winter-flowering Helleborus foetidus (Ranunculaceae

Description: • Background and Aims This study examined the effect of plant traits and environmental factors on pollinator visitation in the winter-flowering Helleborus foetidus (Ranunculaceae) in three distant regions in the Iberian Peninsula. • Methods Geographical variation in floral visitor assemblage, plant ...

The geographic mosaic in predispersal interactions and selection on Helleborus foetidus (Ranunculaceae)

Description: We examine the hierarchical geographic structure of the interaction between a plant, Helleborus foetidus, and its floral herbivores and pollinators (interactors). Six populations from three distant regions of the Iberian Peninsula were used to examine intra- and inter-regional variation in p...

Seedling establishment in Olea europaea: Seed size and microhabitat affect growth and survival

Description: We investigated the effects of seed size and microhabitat on the dynamics of seedling establishment in Olea europaea. We tested the hypothesis that the type of microhabitat suitable for O. europaea recruitment is influenced by microhabitat-specific relationships between seed size and seedling growth...

Geographical variation in the potential of mice to constrain an ant- seed dispersal mutualism

Description: Pre- and post-dispersal Helleborus foetidus (Ranunculaceae) seed predation by mice Apodemus sylvaticus as well as post-dispersal seed removal by ants was studied, during two years, in six plant populations within three geographical regions (Caurel, Cazorla and Ma´gina) of the Iberian Peninsula. ...

Interaction of pollinators and herbivores on plant fitness suggests a pathway for correlated evolution of mutualism- and antagonism-related traits

Description: Different kinds of plant–animal interactions are ordinarily studied in isolation, yet considering the combined fitness effects of mutualistic and antagonistic interactions is essential to understanding plant character evolution. Functional, structural, or phylogenetic associations between attractive...
