The pollination effectiveness of a flower visitor has traditionally been measured as the
product of a quantity component that depends on the frequency of interaction and a quality …

Background Biparental inbreeding, mating between two relatives, occurs at a low frequency
in many natural plant populations, which also often have substantial rates of self-fertilization …

To explain the co-existence and maintenance of females along with hermaphrodite plants,
the female advantage hypothesis has been proposed where females should show greater …

Vegetation clearing, land modification and agricultural intensification have impacted on
many ecological communities around the world. Understanding how species respond to …

Newly formed selfing lineages may express recessive genetic load and suffer inbreeding
depression. This can have a genome-wide genetic basis, or be due to loci linked to genes …

Abstract Background and Aims Gynodioecy is a phylogenetically widespread and important
sexual system where females coexist with hermaphrodites. Because dioecy can arise from …

Assisted gene flow (AGF) can restore fitness in small plant populations. Due to climate
change, current fitness patterns could vary in the future ecological scenario, as highly …

The component Allee effect has been defined as 'a positive relationship between any
measure of individual fitness and the number or density of conspecifics'. Larger plant …

Spatial shifts in insect fauna due to ecological heterogeneity can severely constrain plant
reproduction. Nonetheless, data showing effects of insect visit patterns and intensity of …

Abstract Dianthus morisianus Vals.(Caryophyllaceae) is a narrow endemic species of
Sardinia, growing with only one natural population on the Portixeddu coastal dune system …
