An ideal ecosystem “simulator” would permit the study of ecological questions that are difficult to analyze in the field, and whose details are sometimes not easy to incorporate by means of ab initio computer models. Here, I propose the use of synthetic bacterial systems as such “simulators” by discussing one case study. This is focused on the issue of how certain stressors impact ecosystems that rest on public resources, a fundamental question for risk assessment. We will thus engineer a community that relies on public goods to manage stress. With this “simulator”, I will try to show how the availability of essential resources, and the presence of habitat heterogeneities eventually influence the effect of the stressor. Some surprises are guaranteed.
