Family-level surrogates are too coarse to assess environment-community interactions: A response to Jiang et al. (2019)
Publication date: July 2019Source: Ecological Indicators, Volume 102Author(s): Wei Xiong, Yuzhan Yang, Aibin ZhanAbstractJiang et al. (Ecological Indicators, 2019, 96, 750–752) recently commented on our paper (Xiong et al., 2018a) that we underestimated the effectiveness of family-level surrogates for assessing environment-community interactions. Indeed, they did not properly perform statistical analyses, particularly redundancy analysis models. Even worse, they wrongly recommended the use of family-level surrogates according to their improper analyses. Here we clarify that the use of...
