We might think of flowers in terms of their colour and scent, but what about their temperature? A new review in Annals of Botany looks at the thermal ecology of flowers. In the paper Casper van der Kooi and colleagues...
Many plants produce colourful flowers that play a role in pollinator attraction. These floral visual signals may have distinct optical properties that differ in biological relevance. In this review, van der Kooi et al...
Flower colour plays a major role in the attraction and decision-making of pollinators. Different functional groups of pollinators tend to prefer different flower colours, and therefore may lead to different flower...
Red flowers have evolved repeatedly across angiosperms and are frequently examined in an ecological context. However, less is known about the biochemical basis of red colouration in different taxa. In a recent study...
We currently know little about the evolution of flower colour when multiple pigment families are present. Ellis and Field examined the patterns of evolutionary transitions between anthocyanin-pigmented (red, pink, blue...
The conical epidermal cells found on the petals of most Angiosperm species are so widespread that they have been used as markers of petal identity, but their function has only been analysed in recent years. Whitney et...
