Most plants attract multiple flower visitors that may vary widely in their effectiveness as pollinators. Floral evolution is expected to reflect interactions with the most important pollinators, but few studies have quantified the contribution of different pollinators to current selection on floral traits. To compare selection mediated by diurnal and nocturnal pollinators on floral display and spur length in the rewarding orchid Gymnadenia conopsea, we manipulated the environment by conducting…

Spatial variation in pollinator-mediated selection on phenology, floral display and spur length in the orchid Gymnadenia conopsea.
TLDR
The results demonstrate that spatial variation in interactions with pollinators may result in differences in directional and correlational selection on floral traits in a plant with a semi-generalized pollination system, and suggest that differences in the relative importance of diurnal and nocturnal pollinators can cause variation in selection.
Conflicting selection on floral scent emission in the orchid Gymnadenia conopsea.
TLDR
This study uses electroantennographic data to identify floral scent compounds detected by local pollinators and quantified pollinator-mediated selection on emission rates of 10 target compounds as well as on flowering start, visual display and spur length, demonstrating that minor scent compounds can be targets of selection.
Generalized pollination system: Are floral traits adapted to different pollinators?
TLDR
Flowers of E. chiloensis seem morphologically adapted to hawkmoth pollination, but diurnal and nocturnal pollinators contribute to similar extents to reproductive success and showed a synergic effect on the product of fruit set and seed set.
Diurnal versus nocturnal pollinators and the effect of anthesis onset on the reproductive success of Agarista revoluta (Ericaceae)
TLDR
The results indicate that A. revoluta presents a floral adaptation to nocturnal moths, suggesting specialization to these pollinators and that there is no effect of the period of anthesis onset on plant reproductive success.
Diel pattern of floral scent emission matches the relative importance of diurnal and nocturnal pollinators in populations of Gymnadenia conopsea
TLDR
This study highlights the importance of adding a characterization of diel variation of scent emission rates to comparative studies of floral scent, which so far have often focused on scent composition only.
Floral adaptation to local pollinator guilds in a terrestrial orchid.
TLDR
This study investigated local pollinator adaptation and variation in floral traits in the rewarding orchid Gymnadenia odoratissima, which spans a large altitudinal gradient and thus may depend on different pollinator guilds along this gradient.
Additive effects of pollinators and herbivores result in both conflicting and reinforcing selection on floral traits.
TLDR
The experimental results demonstrate that both pollinators and herbivores can markedly influence the strength of selection on flowering phenology and floral morphology, and cause both conflicting and reinforcing selection, and indicate that the direction ofselection on phenology will vary with the relative intensity of the mutualistic and antagonistic interaction.
Divergent selection on flowering phenology but not on floral morphology between two closely related orchids
TLDR
The results suggest ongoing adaptive differentiation of flowering phenology, strengthening this premating reproductive barrier between the two species.
Vegetation context influences the strength and targets of pollinator-mediated selection in a deceptive orchid.
TLDR
It is demonstrated experimentally that vegetation context can markedly influence the strength of pollinator-mediated selection on visual display traits, and indicate that this effect is weaker for traits affecting pollination efficiency.
The relative importance of diurnal and nocturnal pollinators of Platanthera hologlottis Maxim. (Orchidaceae)
TLDR
Results suggest that the floral traits of P. hologlottis may be specialized for nocturnal flower visitors rather than diurnal flower Visitors, and that the fitness was higher in flowers visited byNocturnal insects than in those visited by diurnal insects.

Pollinator-Mediated Selection on Floral Display and Spur Length in the Orchid Gymnadenia conopsea
TLDR
It is demonstrated that pollinators can mediate selection on both traits likely to be involved in pollinator attraction and traits affecting pollination efficiency and that spatiotemporal variation in the strength of pollinator-mediated selection can contribute substantially to differences in selection between years and populations.
Pollinators exert natural selection on flower size and floral display in Penstemon digitalis.
TLDR
The role of pollinators in selecting floral traits in a herbaceous perennial, Penstemon digitalis, is tested and stronger signatures of selection imposed by pollinators are found than by herbivores and co-flowering plant species.
Pollinator-Mediated Selection on Floral Display and Flowering Time in the Perennial Herb Arabidopsis lyrata
TLDR
The results demonstrate that interactions with pollinators may affect the strength of selection on floral display and the direction ofselection on phenology of flowering in natural plant populations, and support the contention that pollinators can drive the evolution of both floral displays and flowering time.
Pollinator-mediated selection on floral display, spur length and flowering phenology in the deceptive orchid Dactylorhiza lapponica.
TLDR
The results demonstrate that pollinators mediate selection on floral traits likely to affect both pollinator attraction and pollination efficiency, and are consistent with the hypothesis that deceptive species experience strong selection for increased display and mechanical fit between flower and pollinator.
Pollen limitation and natural selection on floral characters in the yellow monkeyflower, Mimulus guttatus.
TLDR
The novel pattern of selection on severely pollen-limited plants suggests that reproductive assurance against pollinator loss may have been directly involved in the floral evolution of closely related selfing taxa.

TLDR
In both measures of pollination effectiveness, nocturnal-visiting moths are better pollinators of S. alba than are the diurnal-Visiting bees, flies, and wasps.

TLDR
Despite the large variation in pollinator abundance over time and space, one species of bumble-bee or hawkmoth tended to predominate in each population each year.
Contribution of diurnal and nocturnal pollinators to the reproductive success of the orchid species Gymnadenia conopsea
TLDR
This study compares pollination services of nocturnal and diumal pollinators to Gymnadenia conopsea, a rare perennial orchid occurring in open grasslands in Europe and Asia, preferably on calcareous soils.
Pollinator specialization and pollination syndromes of three related North American Silene.
TLDR
Compared across the Silene species, divergent floral character states are consistent with increasing the attraction and/ or pollen transfer efficiency of their respective major pollinators, which suggests that the pollinators are past and/or contemporary selective agents for floral trait evolution in these three Silenespecies.
ENVIRONMENT‐DEPENDENT POLLEN LIMITATION AND SELECTION ON FLORAL TRAITS IN AN ALPINE SPECIES
TLDR
This study shows that the commonly assumed pathway from low pollinator availability to strong pollen limitation is not always correct but supports the view that selection on floral traits is positively related to the degree of pollen limitation, and examines how abiotic environmental conditions affect pollen limitation on female reproductive success and pollinator flower visitation.
