Oddly enough, //Datura// leaves are the main food of the hawkmoth's larvae. The evolutionary costs and benefits for both species have been extensively investigated. Population dynamics is much less explored. ===== Assignment ===== Identify the key players of this system and their roles. Propose a model for their population dynamics that take into account the relevant biological information available. ==== Suggested questions ==== * What is the minimal model that predict coexistence of a plant and a pollinator that is also his herbivore ? * Can this minimal model describe properly population dynamics of the system //Datura// / hawkmoth ? If not, what key biological aspect of the system should be considered? ===== References ===== * Bronstein, J.L., T.H. Huxman, and G. Davidowitz (2009).
