There is now compelling evidence of a reduction of pollinator richness and density at a global scale. In this opinion article, we argue that such pollinator decline intensifies pollen limitation and reduces plant reproductive success, threatening natural populations of extinction. We use genetic architecture and selection experiments on floral traits and evaluate the potential for plant reproductive strategies to adapt rapidly to new pollination environments. We propose that plant reproductive strategies could adapt to the current pollinator decline by decreasing or increasing their reliance to pollinators, for example, increasing autonomous selfing or reinforcing interactions with pollinators. We further discuss if and how adaptation of plant reproductive strategies can buffer the demographic consequences of pollinator decline, and possibly rescue plant populations from extinction.
现在有确凿的证据表明，在全球范围内，传粉者的丰富度和密度都有所下降。在这篇观点文章中，我们认为这种传粉者的减少加剧了花粉限制，降低了植物的繁殖成功率，从而威胁到自然种群的灭绝。我们利用花部性状的遗传结构和选择实验，并评估植物繁殖策略对新传粉环境快速适应的潜力。我们提出，植物繁殖策略可以通过减少或增加对传粉者的依赖来适应当前的传粉者减少，例如增加自主自交或加强与传粉者的相互作用。我们进一步讨论了植物繁殖策略的适应是否以及如何缓冲传粉者减少的人口后果，并可能使植物种群免于灭绝。
