Background Floral nectar is an important determinant of plant–pollinator interactions and an
integral component of pollination syndromes, suggesting it is under pollinator-mediated …

Terrestrial orchid life-cycles are complex and dependent on pollinators and mycorrhizal
associates. Worldwide, orchid populations are declining because of urbanization …

Pollinator-driven diversification is thought to be a major source of floral variation in plants.
Our knowledge of this process is, however, limited to indirect assessments of evolutionary …

Floral traits are hypothesized to evolve primarily in response to selection by pollinators.
However, selection can also be mediated by other environmental factors. To understand the …

In animal‐pollinated plants, the opportunity for selection and the strength of pollinator‐
mediated selection are expected to increase with the degree of pollen limitation. However …

A predictive understanding of adaptation to changing environments hinges on a mechanistic
understanding of the extent and causes of variation in natural selection. Estimating variation …

Pollinator-mediated selection to a large extent shapes angiosperm floral diversity, but clearly
not in isolation. To understand how selection by pollinators interacts with other selective …

The individual and combined effects of abiotic factors on pollinator‐mediated selection on
floral traits are not well documented. To examine potential interactive effects of water and …

Flower traits, such as flower size or color changes, can act as honest signals indicating
greater rewards such as nectar; however, nothing is known about shelter-rewarding …

Floral scent is a crucial trait for pollinator attraction. Yet only a handful of studies have
estimated selection on scent in natural populations and no study has quantified the relative …
