Estimated average brood size.

Mean of 3 replicates. SEM = Standard error of the mean. Group letter: Groups that share the same letter (ab) do not statistically differ from each other. Groups with different letters are significantly different from each other (a, b and c). ANOVA, Tukey post-hoc test. Adj. p-value threshold三次重复实验的平均值。SEM为均值标准误（Standard error of the mean）。组字母标注规则：带有相同字母（如ab）的组之间不存在统计学差异；带有不同字母（如a、b、c）的组之间则存在显著统计学差异。采用单因素方差分析（ANOVA）与Tukey事后检验。校正p值阈值。
