Inter-trophic correlations across coarse grain landcover categories.

Kendall's tau-b correlation coefficients, p-values, and sample sizes are shown for comparisons of ordinal densities between linked trophic levels. Letters in common indicate no significant difference between correlation coefficients via Fisher's z compared across landcover categories (within a bi-trophic correlation comparison) at a threshold of p = 0.05. ‘*’ represents a significant pairwise difference in correlation coefficients between trophic levels (within a category and between two bi-trophic correlations in the cherry system).

本结果展示了关联营养级之间有序密度比较的肯德尔τ-b相关系数（Kendall's tau-b correlation coefficients）、p值与样本量。在p=0.05的显著性阈值下，于双营养级相关比较范围内，针对不同土地覆盖类别通过费希尔z检验（Fisher's z）进行比较后，若相关系数间无显著差异，则标注相同字母。符号‘*’代表存在显著的两两相关系数差异：既包括同一类别内不同营养级之间，也包括樱桃系统中两组双营养级相关之间。
