Spatial genetic structure of Aquilegia taxa endemic to the island of Sardinia

Description: Background and Aims The Mediterranean Basin is one of the most important regions for the Earths plant biodiversity; however, the scarcity of studies on fine scale patterns of genetic variation in this region is striking. Here, an assessment is made of the spatial genetic structure of all known locat...

Negative evidence of local adaptation to the establishment conditions in a perennial herb

Description: The differential adaptation of populations of the same species to their local environmental conditions through divergent selection, known as local adaptation, is a key step in the process of diversifica- tion of species. Here, we explore the local adaptation of the perennial mountain herb Helleborus...

Geographical variation in diaspore traits of an ant-dispersed plant (Helleborus foetidus): are ant community composition and diaspore traits correlated?

Description: 1 We explored geographical variation in the interaction between the elaiosome-bearing seeds of Helleborus foetidus and ant dispersers. We looked for correlation across nine Iberian localities, between diaspore traits and structural and functional characteristics of ant communities. 2 Mean diaspore...

A new species of Aquilegia (Ranunculaceae) from Sardinia (Italy)

Description: The new species Aquilegia cremnophila (Ranunculaceae) from the Italian island of Sardinia is here described and illustrated. It occurs in shady rocky crevices, near the upper parts of Mt. Corrasi (Supramontes Region), where it is a member of chasmophilous communities. This species is morphologically...

Effect of plant traits and population structure on the female reproductive success of the endemic Primula elatior subsp. bergidensis (Primulaceae)

Description: his study explores the possible causes of variation in female reproductive success of the subspecific taxon Primula elatior subsp. bergidensis, a distylic endemic to the north-western Iberian Peninsula, by analysing both vegetative and reproductive traits. In three populations, we marked vegetative ...

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. ...

Geographic genetic structure of Iberian columbines (Gen. Aquiliegia)

Description: Southern European columbines (genus Aquilegia) are involved in active processes of diversification, and the Iberian Peninsula offers a privileged observatory to witness the process. Studies on Iberian columbines have provided significant advances on species diversification, but we still lack a compl...
