- | Propose a mathematical model to describe the dynamics of different behavioral strategies concerning sexual canibalism in female and/or male mantids. Your model should take into account that a females can engage in sexual canibalism, and/or that males can react to canibalistic females (e.g. avoiding them). | + | Propose |

+ | * Two different strategies can coexist, and in this kind of systems they were reported to coexist, but there is no apparent reason why would this happen in this situation | ||
