摘要: Spatial variation in plant-pollinator interactions may cause pollinator-mediated selection on floral traits, but to establish this link conclusively experimental studies are needed. We quantified flowering phenology and morphology four populations of the fragrant orchid Gymnadenia conopsea, compared mediated by diurnal nocturnal pollinators two populations. Variation explained most among-population strength directional correlational selection. Pollinators pairs display one trait spur length, a affecting pollination efficiency. Only selected for longer spurs, stronger number flowers with population. The types caused different traits combinations length flowers. results demonstrate that spatial result differences plant semi-generalized system, suggest relative importance can
