The most effective pollinator principle applies to new invasive pollinators
(Royal Society, 2018-06)
G. L. Stebbins' most effective pollinator principle states that when pollinators are not limiting, plants are expected to specialize and adapt to the most abundant and effective pollinator species available. In this study, ...

Pollinator-mediated selection in a specialized pollination system: matches and mismatches among populations
(Wiley Blackwell Publishing, Inc, 2010-09)
Most studies on pollinator-mediated selection have been performed in generalized rather than specialized pollination systems. This situation has impeded evaluation of the extent to which selection acts on attraction or ...
Pollinator-mediated selection in a specialized pollination system: matches and mismatches across populations
(WILEY-BLACKWELL PUBLISHING, 2010-06-17)
Most studies on pollinator-mediated selection have been performed in
generalized rather than specialized pollination systems. This situation has
impeded evaluation of the extent to which selection acts on attraction ...
Do pollinators simultaneously select for inflorescence size and amount of floral scents? An experimental assessment on Escallonia myrtoidea
(BLACKWELL, 2006-11)
Correlation among phenotypic traits may be explained by correlational selection, the simultaneous selection of more than one trait, or by genetic and/or developmental factors. In Escallonia myrtoidea, a tree with scented ...
Reproductive assurance weakens pollinator-mediated selection on flower size in an annual mixed-mating species
(Oxford University Press, 2019-02)
Background and Aims In animal-pollinated plants, direct and indirect selection for large and small flowers in predominantly outcrossing and selfing species, respectively, is a common consequence of pollen limitation (PL). ...
Pollinator-mediated selection on the nectar guide phenotype in the Andean monkey flower, Mimulus luteus
(Ecological Society of America, 2003)
Mimulus luteus (Scrophulariaceae) is a perennial herb occurring in the South
American Andes that shows a wide variation in the size and shape of a red spot on the
lower lobe of the yellow flower. We describe the preference ...
The influence of insects and hummingbirds on the geographical variation of the flower phenotype in Mimulus luteus
(BLACKWELL, 2007-12)
We describe the geographical variation of corolla and nectar guide size in seven populations of Mimulus luteus (Phrymaceae) in central Chile, and examine whether flower phenotypes associate with taxonomic composition and ...

Phylogenetic analysis of floral integration in Schizanthus (Solanaceae): Does pollination truly integrate corolla traits?
(2007)
To assess whether floral integration patterns result from the action of pollinator selection on functionally related traits, we compared corolla integration patterns in eight Schizanthus species differing in pollination ...
