BACKGROUND AND AIMS Flower colour varies within and among populations of the Rocky Mountain columbine, Aquilegia coerulea, in conjunction with the abundance of its two major pollinators, hawkmoths and bumble-bees. This study seeks to understand whether the choice of flower colour by these major pollinators can help explain the variation in flower colour observed in A. coerulea populations. ME...

Flowers are a key source of released fragrance volatiles in the biotic world. Despite fact that volatile organic compounds (VOCs) have low molecular weights, polarity, and vapour pressures, process release is influenced by floral tissue’s morphology, anatomy, cellular properties. Polianthestuberosa L. flowering plant Agavaceae family (also known as Asparagaceae Amaryllidaceae some botanists) co...

Sexual dimorphism is one of the most widespread and recognizable patterns of phenotypic variation in the biotic world. Sexual dimorphism in floral display is striking in the dioecious plant Silene latifolia, with males making many, small flowers compared to females. We investigated this dimorphism via artificial selection on two populations to determine whether genetic variation exists within p...
