Anna Depetris: Microbial Cooperation

Different selective advantages determine the evolution of microbial social behaviors. Living in communities such as biofilms provides microbes with protection against environmental fluctuations and stresses. Nonetheless, the formation of closely dependent social systems comes at some costs. For instance, evolutionary cheaters may undermine the sustainability of these communities. Ultimately, the balance between costs and benefits of cooperation depends on the surrounding environmental conditions. My work focuses on the effects of different environmental factors in shaping microbial social interactions.
