Figure 4. Features of interaction and network.

(a), Probability density of distance between two males, for interacting and non-interacting pairs. (b), Probability of interacting with kth-neighbor. (c), Duration of interaction, i.e., the period of time that the correlation value stays above the threshold. (d), Probability of the size of subgroup in which a male may be included at each moment for subgroup sizes greater than one. The result is compared to a reference null model with randomized edges²³. (e), Number of subgroups versus swarm size with linear regression passing through the origin.
