Results of hierarchical generalized linear mixed models of PC1 (grass structure) in relation to kangaroo density and tree canopy class (dummy variable) showing trends (Slope) including standard errors (SE).

Grassland has been used as a reference level for tree canopy class categories. Significance is indicated by the Wald statistic (χ2) and p-value as follows: *pResults of hierarchical generalized linear mixed models of PC1 (grass structure) in relation to kangaroo density and tree canopy class (dummy variable) showing trends (Slope) including standard errors (SE).草原已被用作林冠（tree canopy）类别的参照水平。显著性通过瓦尔德统计量（Wald statistic，χ²）与p值（p-value）进行判定，具体如下：*p。针对主成分1（PC1，对应草原结构）与袋鼠密度、林冠类别（虚拟变量dummy variable）的分层广义线性混合模型（hierarchical generalized linear mixed models）分析结果，展示了包含标准误（SE）的趋势（斜率）。
