Why do some columbines make life harder for their pollinators?
The flowers of Aquilegia eximia, the serpentine columbine, face downward, but the hummingbirds that pollinate it prefer horizontal flowers, so why do the flowers face the wrong way?

The flowers of Aquilegia eximia, the serpentine columbine, face downward, but the hummingbirds that pollinate it prefer horizontal flowers, so why do the flowers face the wrong way?
The alpine plant Ranunculus kuepferi can face spring frosts while growing reproductive organs. Does the cold explain why sometimes the plant doesn’t bother with sex?
This study uses dual choice assays and experimental arrays of blue and white flowers to determine pollinators’ preference for flower colour in Aquilegia.
