Data and code from "Biodiversity loss underlies the dilution effect of biodiversity"

The dilution effect predicts increasing biodiversity to reduce the risk of infection, but the generality of this effect remains unresolved. Because biodiversity loss generates predictable changes in host community competence, we hypothesized that biodiversity loss might drive the dilution effect. In this file, we test this hypothesis by reanalyzing four previously published meta-analyses that came to contradictory conclusions regarding generality of the dilution effect.稀释效应（dilution effect）理论预测，生物多样性提升可降低感染风险，但该效应的普适性仍未得到明确验证。鉴于生物多样性丧失会使宿主群落的感染适宜性发生可预测的变化，我们提出如下假说：生物多样性丧失可能驱动稀释效应的产生。本数据集通过重新分析四项此前已发表的荟萃分析（meta-analyses）检验上述假说——这些荟萃分析针对稀释效应的普适性得出了相互矛盾的结论。
