有利于稀有物种的机制是维持多样化群落的关键1-3。保护开花植物生物多样性的最关键任务之一是了解植物与传粉媒介的相互作用如何有助于稀有物种的维持4-7。在这里，我们使用系统发育结构方程模型，将植物-传粉者和种间花粉转移网络与花卉功能性状相结合，表明传粉者使用中的生态位划分和不对称促进赋予了生物多样性热点中稀有物种的适应性优势。共花物种通过花特征过滤传粉媒介，而较稀有的物种表现出更大的传粉媒介专业化，导致比更丰富的物种更高的授粉介导的雄性和雌性适应性。当植物共享传粉媒介资源时，通过花粉运输动力学的不对称促进以牺牲更丰富的物种为代价，使更稀有的物种受益，作为一种替代的多样性促进机制。我们的结果强调了社区范围内的植物与传粉者相互作用的重要性，这种相互作用影响着生物多样性维持的繁殖。作者表明，植物与传粉媒介的相互作用为生物多样性热点地区的稀有植物物种带来了适应性优势。
Mechanisms that favour rare species are key to the maintenance of diverse communities1–3. One of the most critical tasks for conservation of flowering plant biodiversity is to understand how plant–pollinator interactions contribute to the maintenance of rare species4–7. Here we show that niche partitioning in pollinator use and asymmetric facilitation confer fitness advantage of rarer species in a biodiversity hotspot using phylogenetic structural equation modelling that integrates plant–pollinator and interspecific pollen transfer networks with floral functional traits. Co-flowering species filtered pollinators via floral traits, and rarer species showed greater pollinator specialization leading to higher pollination-mediated male and female fitness than more abundant species. When plants shared pollinator resources, asymmetric facilitation via pollen transport dynamics benefitted the rarer species at the cost of more abundant species, serving as an alternative diversity-promoting mechanism. Our results emphasize the importance of community-wide plant–pollinator interactions that affect reproduction for biodiversity maintenance. The authors show that plant–pollinator interactions confer a fitness advantage to rare plant species in a biodiversity hotspot.
