Analyses of changes in size, shell-weight and body-weight of large limpets.*

*Treatment (Tr) was fixed with 5 levels (3L, + macroalgae; 3L +10S, +/− macroalgae; 13L, +/− macroalgae); Plots (Pl) was nested in Tr with 2 levels. The replicates were the limpets (n = 2). Only 1 tagged individual remained from the 3L treatment without macroalgae. So, this treatment was not included in the analysis and the factor Macroalgae was removed. Cochran's test (C) was used to test assumptions of homogeneity. Non-significant interactions (x) were pooled when ns with PPP>0.05.实验处理组（Tr，Treatment）共设置5个水平，分别为3L组（添加大型藻类）、3L+10S组（±添加大型藻类）、13L组（±添加大型藻类）；样方（Pl，Plots）嵌套于实验处理组中，共设2个水平。实验重复单元为帽贝，每组重复次数为n=2。但无大型藻类添加的3L处理组仅剩余1个带标记的个体，因此该处理组未纳入后续分析，且移除“大型藻类”因子。本研究采用科克伦检验（Cochran's test，C）对数据的方差齐性假设进行检验。当交互效应无统计学显著性（ns）且P>0.05时，可将标注为x的非显著交互作用予以合并。
