Is early flowering in myrmecochorous plants an adaptation for ant dispersal?

Description: To analyze the extent to which early flowering of specialized myrmecochorous plants (i.e. plants producing elaiosome-bearing seeds) may be the result of adaptation for ant dispersal, we investigated flowering and fruiting patterns of common herb and shrub-layer species in a beechwood forest at the w...

Fuentes de variación en el tamaño de la semilla de la herbácea perenne Helleborus foetidus L. (Ranunculaceae)

Description: Seed size is one of the plant traits more thoroughly studied in plant sciences due to its pivoting ecological position between dispersal processes and emergence, survival and establishment of plant species. Frequently, most seed size variation is located within plant, exceeding variation between pla...

Influence of elaiosome on postdispersal dynamics of an ant-dispersed plant

Description: Specialized myrmecochorous plants bear an elaiosome attached to the seed. Ants benefit from food provided by this appendage and plants get their seeds eventually dispersed. Aside from the benefits conferred by seed dispersal, we hypothesize that the influence of the elaiosome might extend to late...

Regional and local variation in seedling emergence, mortality and recruitment of a perennial herb in Mediterranean mountain habitats

Description: Spatial patterns of seedling regener- ation of woody Mediterranean plants are widely documented, with seedlings and juve- niles growing almost exclusively under shrub and tree canopy. Neighbourhood habitat ame- lioration and consequent facilitative effects on r...

Pre- and post-germination determinants of spatial variation in recruitment in the perennial herb Helleborus foetidus L. (Ranunculaceae)

Description: 1 Recruitment in plant populations is a multiphase sequential process. An integrated view of the relationships between the stages and processes involved is therefore needed, but few studies have analysed the direct and indirect effects concerned. We propose a causal model of these relationships a...

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...

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...
