Treatment effects on food web variables.

Results of linear mixed-effects modeling of food web variables as a function of experimental treatment. Effect sizes are given for the three planned contrasts: high vs. low SL variance (HV–LV); fish present vs. absent (Fish – NF); enclosed vs. outside enclosures (In – Out), while the random block effect was included in the model but is not shown. Significant or marginally significant effects are indicated in boldface () or italics (). Variables marked with an asterisk (*) were log-transformed to improve normality.食物网变量随实验处理变化的线性混合效应模型（linear mixed-effects modeling）分析结果。本次分析给出了三项预设对照的效应量：高与低体长（SL）方差组（HV–LV）、有鱼组与无鱼组（Fish – NF）以及围栏内与围栏外组（In – Out）；模型中纳入了随机区组效应（random block effect），但未在此处展示。显著或边际显著的效应以粗体（boldface）或斜体（italics）标注。标有星号（*）的变量已进行对数转换以改善正态性。
