Goodness of fit tests for a random (Poisson) or aggregated distribution (Morisita’s Standarised Index of Dispersion).

*denotes significant difference from a Poisson distribution (p<0.05). ∧denotes a significant departure from randomness at p<0.05.* 表示与泊松分布（Poisson distribution）存在显著差异（p<0.05）。∧ 表示在p<0.05水平下与随机性存在显著偏离。
