Effects of vertebrate exclusion, tree age, and study site on leaf damage.

Statistical results (generalized linear mixed models with log likelihood estimates and AIC) of the analysis of the effects of vertebrate exclusion, tree age, and study site on leaf damage given as mean damage of leaf area (%) and mean number of holes per leaf. Significance of treatments were tested by model comparison fitted with (Model 1) and without factor “exclusion”, “age”, or “site”, respectively (Model 2) with the anova command in R 2.10.0 based on model deviances.

本数据集包含针对脊椎动物排除、树木树龄与研究样地对叶片损伤影响的分析统计结果：分析采用广义线性混合模型（generalized linear mixed models）构建，附带对数似然估计值与赤池信息准则（Akaike Information Criterion, AIC）；叶片损伤以叶片面积平均损伤百分比（%）及单叶平均穿孔数两种指标量化。各组处理的显著性通过模型对比法检验：针对“排除”“树龄”“样地”三个因子，分别构建包含对应因子的模型（模型1）与不包含该因子的对照模型（模型2），并基于模型偏差值，使用R 2.10.0软件中的anova命令完成显著性检验。
