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

Background Obtaining an optimal flower temperature can be crucial for plant reproduction
because temperature mediates flower growth and development, pollen and ovule viability …

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 …

Glasshouse plants are species that trap warmth via specialized morphology and physiology,
mimicking a human glasshouse. In the Himalayan alpine region, the highly specialized …

Floral colour is a key reproductive character, often associated with environmental
adaptation, and subject to human intervention. A large number of Rhododendron species …

The flower perianth has various, non‐mutually exclusive functions, such as visual signalling
to pollinators and protecting the reproductive organs from the elements and from florivores …

Buttercup (Ranunculus spp.) flowers are exceptional because they feature a distinct gloss
(mirror-like reflection) in addition to their matte-yellow coloration. We investigated the optical …

Studies on animal colour vision typically focus on the chromatic aspect of colour, which is
related to the spectral distribution, and disregard the achromatic aspect, which is related to …

The colour vision system of bees and humans differs mainly in that, contrary to humans,
bees are sensitive to ultraviolet light and insensitive to red light. The synopsis of a colour …

Honey bees (Apis mellifera Linnaeus, 1758) potentially rely on a variety of visual cues when
searching for flowers in the environment. Both chromatic and achromatic (brightness) …
