Flowering plants are a major component of terrestrial ecosystems, and most of them depend on animal pollinators for reproduction. Thus, the mutualism between flowering plants and their pollinators is a keystone ecological relationship in both natural and agricultural ecosystems. Though plant-pollinator interactions have received considerable amount of attention, there are still many unanswered questions. In this paper, we use methods of evolutionary game theory to investigate the co-evolution of floral advertisement and pollinator preferences Our results indicate that competition for pollination services among plant species can in some cases lead to specialization of the pollinator population to a single plant species (oligolecty). However, collecting pollen from multiple plants - at least at the population level - is evolutionarily stable under a wider parameter range. Finally, we show that, in the presence of pollinators, plants that optimize their investment in attracting vs. rewarding visiting pollinators outcompete plants that do not.
开花植物是陆地生态系统的主要组成部分，其中大多数依靠动物传粉者进行繁殖。因此，开花植物与其传粉者之间的共生关系是自然生态系统和农业生态系统中的关键生态关系。尽管植物 - 传粉者相互作用已受到大量关注，但仍存在许多未解决的问题。在本文中，我们运用进化博弈论方法来研究花卉广告与传粉者偏好的共同进化。我们的结果表明，植物物种间对传粉服务的竞争在某些情况下会导致传粉者种群专门针对单一植物物种（寡食性）。然而，从多种植物收集花粉——至少在种群水平上——在更广泛的参数范围内是进化稳定的。最后，我们表明，在有传粉者存在的情况下，优化吸引与回报来访传粉者投资的植物比未优化的植物更具竞争力。
