Greatest longitudinal length (cm) for seeds collected with and without ants and those eaten by Cacajao and collected directly under trees with no ants

The data set shows lengths (mm) of Macrolobium fruits collected from trees that had, and which did not have, colonies of Pseudomyrmex ants. Measurements for fruits collected beneath trees with no ants are provided (there were too few under trees with ants for statistical analysis and these are therefore not included in the data set)

本数据集记录了采集自两类植株的阔荚豆属（Macrolobium）果实的长度（单位：毫米），两类植株分别为携带有伪切叶蚁属（Pseudomyrmex）蚁群的树木，以及无该类蚁群的树木。本次仅提供了无蚁群树木下方采集的果实测量数据——由于有蚁群树木下方的果实样本量过少，无法满足统计分析要求，故未将此类样本纳入本数据集。
