Diet composition of Guanapo River guppies from high predation (HP; N = 21) and low predation (LP; N = 21) sites during the dry season (data from [28]).

Proportions of the 3 food items are estimated marginal means (±SE) calculated by the MANCOVA (population of origin as the fixed effect and fish length as a covariate); data reported have been back-transformed.三种食物组分的占比为通过多元协方差分析（Multivariate Analysis of Covariance, MANCOVA）计算得到的估计边际均值（±标准误，Standard Error, SE），该分析以种群来源作为固定效应，鱼类体长作为协变量；所报告的数据均经过逆转换处理。
