Abstract

A mechanism to generate spatially segregated territories in two dimensions consists of individuals depositing their own marks and avoiding foreign ones. This form of environment-mediated interaction, called stigmergy, makes the emerging spatiotemporal territory dynamics quite rich. Short-lived marks produce rapidly morphing and highly mobile territories. Long-lived marks yield slow territories with a narrowly defined shape distribution. The change in territory mobility depending on the time for which individual marks remain active is accompanied by a liquid-hexatic-solid transition akin to the Kosterlitz-Thouless melting scenario.
