Down the tube: pollinators, predators, and the evolution of flower shape in the alpine skypilot, Polemonium viscosum.

Evolution; international journal of organic evolution - 1 Oct 2001

Galen C, Cuba J

Abstract excerpt

We address how a conflict between pollinator attraction and avoidance of flower predation influences the evolution of flower shape in Polemonium viscosum. Flower shape in P. viscosum is the product of an isometric relationship between genetically correlated (rA = 0.70) corolla flare and length. Bumblebee pollinators preferentially visit flowers that are more flared and have longer tubes, selecting for a...
