植物-传粉者相互作用网络是一个动态的实体，植物物候的季节变化可以在短时间尺度和长时间尺度上重塑其结构。然而，这种季节性的动态很少被考虑，特别是对于海洋岛屿授粉网络。在这里，我们评估的时间动态的变化，植物传粉者的相互作用，在海洋岛屿社区的花卉资源丰富度的季节性变化。方法对永兴岛群落传粉网络的季节变化进行分析。四个时间的定性授粉网络进行了分析，使用四个季节的植物-传粉者相互作用的数据。我们收集了四个季节中每个季节连续两个月的植物传粉者相互作用的数据。计算了四个网络级指数来表征网络的整体结构。社区差异的统计分析被用来比较这个社区在四个季节，探索驱动这些模式的潜在因素。我们还评估了植物和传粉者功能组的两个物种水平指数的时间变化。重要结果网络级专业化和模块化表现出显着相反的趋势，植物物种丰富度在四个季节。植物物种数量的增加可能会促进传粉者之间的竞争，导致生态位重叠增加，导致专业化和模块化下降，反之亦然。进一步的分析表明，季节到季节的营业额的相互作用占主导地位的相互作用重新布线。因此，季节性变化的生态位重叠传粉者之间的相互作用重新布线，从而推动互动周转在这个社区。与其他传粉者功能群相比，天蛾具有较高的专化值，蜜蜂科具有较高的物种强度值。这些发现应该被认为是在探索孤立的海洋岛屿生态系统和其他生态系统中植物-传粉者相互作用的基础。
Aims Plant–pollinator interaction networks are dynamic entities, and seasonal variation in plant phenology can reshape their structure on both short and long timescales. However, such seasonal dynamics are rarely considered, especially for oceanic island pollination networks. Here, we assess changes in the temporal dynamics of plant–pollinator interactions in response to seasonal variation in flo al resource richness in oceanic island communities. Methods We evaluated seasonal variations of pollination networks in the Yongxing Island community. Four temporal qualitative pollination networks were analyzed using plant–pollinator interaction data of the four seasons. We collected data on plant–pollinator interactions during two consecutive months in each of the four seasons. Four network-level indices were calculated to characterize the overall structure of the networks. Statistical analyses of community dissimilarity were used to compare this community across four seasons to explore the underlying factors driving these patterns. We also evaluated the temporal variation in two species-level indices of plant and pollinator functional groups. Important Findings Both network-level specialization and modularity showed a significantly opposite trend compared with plant species richness across four seasons. Increased numbers of plant species might promote greater competition among pollinators, leading to increased niche overlap and causing decreased specialization and modularity and vice versa. Further analyses suggested that the season-to-season turnover of interactions was dominated by interaction rewiring. Thus, the seasonal changes in niche overlap among pollinators lead to interaction rewiring, which drives interaction turnover in this community. Hawkmoths had higher values of specialization and Apidae had higher values of species strength compared with other pollinator functional groups. These findings should be considered hen exploring plant–pollinator interactions in ecosystems of isolated oceanic islands and in other ecosystems.
