The relationship between native species richness and exotic species richness or occurrence will always be negative when the total number of species is accounted for in statistical models: A response to Beaury et al.

Beaury et al. (2020) attempt to address the scale dependence of evidence for biotic resistance by including environmental covariates that can account for total species richness. However, this approach will incorrectly estimate relationships, driven by the accuracy of the covariates rather than the true relationship between native and exotic species.

当在统计模型中考虑物种总数时,本地物种丰富度与外来物种丰富度或发生率之间的关系将始终为负:对 Beaury 等人的回应。

博里等人。(2020) 试图通过包括可以解释总物种丰富度的环境协变量来解决生物抗性证据的规模依赖性。然而,这种方法会错误地估计关系,这是由协变量的准确性而不是本地和外来物种之间的真实关系驱动的。
