Background Flower coloration is a key enabler for pollinator attraction. Floral visual signals
comprise several components that are generated by specific anatomical structures and …

The evolution of floral traits in animal-pollinated plants involves the interaction between
flowers as signal senders and pollinators as signal receivers. Flower colors are very diverse …

Colour is one of the most obvious advertisements of flowers, and occurs in a huge diversity
among the angiosperms. Flower colour is responsible for attraction from a distance, whereas …

Angiosperm flowers have evolved a dazzling palette of colours and a rich bouquet of scents,
principally serving to attract pollinators. Despite recent progress in the ecology of pollination …

Flowers are complex structures, synchronously displaying both olfactory and visual
signals/cues in the context of a particular floral morphology, that also vary in resource …

Flower colour is mainly due to the presence and type of pigments. Pollinator preferences
impose selection on flower colour that ultimately acts on flower pigments. Knowing how …

Colour signals are the main floral trait for plant–pollinator communication. Owing to visual
specificities, flower visitors exert different selective pressures on flower colour signals of …

Pollinators make foraging decisions based on numerous floral traits, including nectar and
pollen rewards, and associated visual and olfactory cues. For insect‐pollinated crops …

The coloration of flowers is due to the wavelength-selective absorption by pigments of light
backscattered by structures inside the petals. We investigated the optical properties of …

The high variability observed in floral traits has been interpreted as resulting from the
adaptation of plants to pollinators, as the latter present innate preferences for specific floral …
