Abstract
We study the spatial pattern formation and emerging long-range correla tions in a model of three species coevolving in space and time accordi ng to stochastic contact rules. Analytical results for the pair correl ation functions, based on a truncation approximation and supported by computer simulations, reveal emergent strategies of survival for minor ity agents based on selection of patterns. Minority agents exhibit def ensive clustering and cooperative behavior close to phase transitions.
