Ecology Brunet, Johanne [1], Van Etten , Megan [2]. The impact of temperature and water availability on floral traits influencing pollinator attraction and plant mating system. Temperature and spring and early summer rainfall are expected to increase in high-altitude habitats in response to global warming. Such environmental changes could influence floral traits with consequences for pollinator attraction and plant mating system. To mimic environmental changes associated with global warming in high-altitude habitats, we grew A. coerulea plants from 17 families from each of three natural populations at two temperatures and two water regimes. We measured a variety of floral traits with potential impact on pollinator attraction and/or plant mating system. Temperature and/or water affected most floral traits except for flower chroma, hue and nectar concentration. We observed phenotypic plasticity for various floral traits in response to changes in environmental factors associated with global warming. We detected a genetic basis for many floral traits. We discuss the implications of these results for the evolution of floral traits in response to global warming and the potential impact on pollinator attraction and plant mating system.
