Table 2 Community level network metrics for the standard dataset, showing observed network metrics, mean and standard deviation of null model predictions (1000 null models) and metrics corrected by null model predictions. Number of interactions are controlled for in the null model, so are not predicted. Observed values in bold are significantly different from null model predictions (p < 0.001).
