植物及其传粉媒介可能对环境变化（如气候变暖）的反应有所不同。结果，授粉媒介是否可以成功跟踪植物的迁移并重建有效的授粉媒介网络对于相互关系，尤其是强大的互惠性至关重要。 FICUS Altissima是一棵通常种植的树木，提供了一个机会，可以确定其强制性授粉的黄蜂物种Eupristina Altissima是否可以跟踪其宿主的范围扩展。使用mtDNA COI基因，我们发现E. altissima是F. altissima介绍的唯一授粉媒介物种，从而确认该特定的授粉媒介可以跟踪其宿主无花果树的范围扩展。但是，使用COI基因和微卫星标记的种群遗传分析检测到遗传变异的显着降低（MTDNA单倍型的数量和基于微卫星的遗传多样性指数），并且在扩展分布范围内的种群之间的分化增强。这些发现与创始人事件的后果一致。我们的发现表明，人工引入引起的植物范围扩展可能不会像以前预期的那样损失传粉媒介，即使在极端义务的互惠中，例如无花果 - 金字WASP系统，当时传粉媒介可以积极或被动地分散长距离。
Plants and their pollinators may respond differently to environmental changes like climate warming. As a consequence, whether the pollinators can successfully track the migration of the plants and rebuild an effective pollinator network are crucial for mutualistic relationships, especially obligate mutualisms. Ficus altissima is a commonly planted tree out of its native range, providing an opportunity to determine if its obligatory pollinating wasp species, Eupristina altissima, can track the range expansion of its host. Using mtDNA COI gene, we found that E. altissima is the only pollinator species at introduced sites of F. altissima, thereby confirming that this specific pollinator can track the range expansion of its host fig tree. However, population genetic analysis using both COI gene and microsatellite markers detected a significant reduction in genetic variation (number of mtDNA haplotypes and microsatellite-based genetic diversity indices) and an enhanced differentiation among populations within the expanded distribution range. These findings are consistent with the consequences of founder events. Our findings suggest that plant range expansion caused by artificial introduction may not suffer from loss of pollinators as previously expected, even within the extremely obligate mutualisms such as the fig-fig wasp system, when pollinators can disperse, actively or passively, over long distances.
