Pollination context and abiotic stress reshape variation in floral longevity and its exposure to selection

Floral longevity is thought to evolve by natural selection imposed by pollinators and resource constraints acting on heritable phenotypic variation. In species with pollination-induced wilting, pollination rates may also influence expression of variation, raising questions of how and when floral longevity is shaped by adaptation. We created an experimental range of pollen deposition rates in a wild population of Sabatia angularis (Gentianaceae) against the backdrop of natural abiotic variation. We investigated how pollination environment affected expression of longevity, distribution of variation, phenotypic correlations, and predispersal seed predation risk. We evaluated whether any effects of abiotic factors are modified by pollination environment. Mean and variance in floral longevity declined with increasing pollen deposition rates, and phenotypic distributions became increasingly compressed. Nevertheless, we detected a flower lifespan-number trade-off and positive flower lifespan-s..., , # Pollination context and abiotic stress reshape variation in floral longevity and its exposure to selection
