+===== Introduction =====
-The evolution of species traits is driven by different selective pressures, which can be determined by species interactions. If different interactions can lead to distinct selective pressures, the overall combination of each interactions' relative contribution will determine species traits. //Primula farinosa// is a perennial herb with two different types of floral morphs, a short morph and a tall morph. Antagonistic interactions such as herbivores that consume flores favor a short floral morph, whereas pollinators are more attracted by tall floral morph. Ågren and colleagues (2013) found geographical variation in the distribution of floral morphs from //P. farinosa// along with variation in the strength of interaction with herbivores and pollinators.

 ===== Assignment =====
-Unravel the relative contribution of mutualistic vs antagonistic interaction for the adaptive differentiation of floral morph in a perennial herb
+Propose a simple but realistic mathematical model that unravels the relative contribution of mutualistic //vs.// antagonistic interactions for the adaptive differentiation of floral morph in this system. Use this model to explore the ecological and/or evolutionary consequences of the proposed dynamics.
 ===== Proposed questions =====
-  *Floral dimorphism in //Primula farinosa// is geographically structured. Can a simple model, with no geographic structure result in floral dimorphism?
+  *Floral dimorphism in //Primula farinosa// is geographically structured. Can a simple model, with no explicit spatial structure result in floral dimorphism?
   *How the strength of each type of interaction (mutualistic and antagonistic) determines the frequencies of floral morphs?
