Understanding and predicting how spatial and temporal variability of a resource affects the social behavior of interacting agents ("harvesters") is a fundamental problem in many social-ecological systems. Here we propose a simple, yet generic, lattice-based evolutionary model, to investigate the dependence of evolutionary stable social strategies on the spatial distribution and the effective life-time of the resource landscape. In particular, we identify distinct parameter region which favor different behavioral strategies: territoriality, individualism and information sharing. Finally, we discuss briefly the results of an agent-based model in continuous time and space together with a simplified analytical description, which fully align with our lattice-model results.
