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...

Adaptive advantages of myrmecochory: The predator-avoidance hypothesis tested over a wide geographic range

Description: The predator-avoidance hypothesis states that once released from the parent plant, myrmecochorous seeds are rapidly taken by ants to their nests, where they are protected from predators. Previous studies conducted to test this hypothesis have frequently neglected two major aspects necessary for its ...

Geographic and temporal variation in the ant-seed dispersal assemblage of the perennial herb Helleborus foetidus L. (Ranunculaceae)

Description: Spatio-temporal variations in the composition of the animal interactive assemblages may result in variations in selective pressures on the plants. In ant-seed dispersal mutualisms, the study of the magnitude of spatial and temporal variation of ant assemblages is rarely studied, limiting inferences ...

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...
