宿主对单个寄生虫物种的易感性的种内变异是常见的，但这些效应如何调节自然界中不同寄生虫群落的结构还不太清楚。为了解决这一知识差距，我们测试了宿主的遗传特性如何影响寄生虫群落恢复珊瑚礁与青少年牡蛎从不同的来源，一个区域的商业孵化场或两个野生祖先线之一。我们评估了恢复后4年的三个微型和两个大型寄生虫物种的患病率和强度。尽管恢复珊瑚礁的空间接近，牡蛎源身份强烈预测寄生虫群落患病率在所有年份，不同来源的相对易感性不同的寄生虫。牡蛎种子源还预测了珊瑚礁水平的寄生虫强度跨越空间和时间。我们的研究结果强调，宿主种内变异可以塑造自然系统中的寄生虫群落结构，并加强了在恢复设计中考虑来源身份和多样性的重要性。

Intraspecific variation in host susceptibility to individual parasite species is common, yet how these effects scale to mediate the structure of diverse parasite communities in nature is less well understood. To address this knowledge gap, we tested how host genetic identity affects parasite communities on restored reefs seeded with juvenile oysters from different sources—a regional commercial hatchery or one of two wild progenitor lines. We assessed prevalence and intensity of three micro- and two macroparasite species for 4 years following restoration. Despite the spatial proximity of restored reefs, oyster source identity strongly predicted parasite community prevalence across all years, with sources varying in their relative susceptibility to different parasites. Oyster seed source also predicted reef-level parasite intensities across space and through time. Our results highlight that host intraspecific variation can shape parasite community structure in natural systems, and reinforce the importance of considering source identity and diversity in restoration design.
