abstract = {The evolution of plant pollination systems is one of the main subjects of
debate in the fore of pollination biology. Along the gradient of specializationgeneralization,
generalist plants exist in higher frequencies than those expected
by some theoretical expectancies. Plants with this pollination system exhibit
great spatio-temporal variations in the pollinator assemblage that manifests at
different scales, from the populational to the individual level. At the individual
level this variation has been considered to be random and extent of any
functionality. However, there exist evidences against this thought.
We think that generalization might result from a pollinator-mediated
evolution in what we have labeled structured generalization. In this hypothesis
the individual level of generalization is associated to plant phenotype and
genotype as a result of the different preferences of pollinators. The individual
generalization will affect to the plant’s reproductive output and result in an
assortative mating. Consequently, the populational genetic structure may be
affected and phenotypic and genetic divergences may arise if this structure is
maintain over time.
In this study we explore the basis of the structured generalization from
its causes to its effects on the population genetic structure. To do so, we
use the generalist plant species Erysimum mediohispanicum (Brassicaceae) as
a species model. In a natural population and in two experimental plots we
monitorized a series of marked individuals during their flowering time. For
each individual plant, we characterized its phenotype and microenvironment
and surveyed all plant interactions with its pollinators along the flowering
season. Additionally, we genotyped each marked individual as well as part of
their progeny. Finally, we characterized the effectiveness of pollination of the
different functional groups visiting the flowers of E. mediohispanicum.},
