The effect of global climate change on plant–pollinator interaction is not limited to changes in phenology and richness within communities but also includes the spatial mismatch caused by the inconsistency of geographical distribution changes. Subsequently, the pollinator interaction network may be remodeled or even disrupted. In this study, we simulated the suitable habitat niche of 15 species and their eight pollinator species as well as their overlapping versus geographical mismatch under the current and three future climate change scenarios in 2090s, using MaxEnt. Results showed that the suitable habitat of all species would decrease in 2090s. In particular, 10, 8, and 13 n–pollinator assemblages would have a reduced spatial match region under the climate change scenarios, mainly due to the contraction of the suitable habitat of species. The results provide novel insights into the response of plant–pollinator interactions to global warming, useful to prioritize conservation actions of alpine plant ecosystems.

气候变化下高山杜鹃种群数量减少导致其传粉媒介空间分布不匹配

全球气候变化对植物-传粉媒介相互作用的影响不仅限于群落内物候和丰富度的变化，还包括地理分布变化不一致引起的空间错配。随后，传粉媒介相互作用网络可能会被重塑甚至被破坏。在这项研究中，我们使用 MaxEnt 模拟了 2090 年代当前和三种未来气候变化情景下 15 个物种及其 8 个传粉媒介物种的适宜栖息地生态位，以及它们的重叠与地理不匹配。结果表明，到2090年代，所有物种的适宜栖息地都会减少。特别是，在气候变化情景下，10、8和13个n传粉昆虫组合的空间匹配区域会减少，这主要是由于物种适宜栖息地的收缩。研究结果为植物与传粉者相互作用对全球变暖的反应提供了新的见解，有助于优先考虑高山植物生态系统的保护行动。
