According to number of woodlice initially introduced, the dynamics of the dispersion of groups held for 300 s (a) and the time necessary to disperse 50% of the population introduced (half-life time) (b).
For the experiment with 120 woodlice, only the first 1500 s were represented in Fig 1a for better visibility, but some aggregates persisted for more than 4300 s with 120 individuals.

According to the initial retention time of individuals, the dynamics of dispersion of groups of 40 woodlice (a) and the time necessary to disperse 50% of the population introduced (half-life time) (b).
