+===== Introduction =====
+Insectivorous plants benefit from trapped, dead insects as a source of nutrients. On the other hand, most of these plants also depend on free-moving, live insects as pollen vectors for sexual reproduction.
+This pollinator-prey conflict can be resolved by temporal separation of flower and trap development through the life-history of individuals.
+Spatial segregation of both systems can also resolve this conflict, as illustrated here by two //Drosera// species (//D. spatulata// and //D. arcturi//; Figures 1A-B).
+Other species (such as //D. auriculata//; Figure 1C) are able to produce distinct chemical signaling profiles for flowers and traps, thus relying on the ability of pollinators to differentiate between these chemical cues.
+Nonetheless, even in the presence of such traits, potential pollinators may end trapped by their mutualistic partners.

+===== Assignment =====
+Develop a mathematical model that represents the dynamics of population densities on pollinator-prey conflicts in carnivorous plants and explore the implied consequences for these species.
+===== Suggestions and Questions =====
+Initially, you may consider a system with three components: one for carnivorous plant density, one for pollinator density, and one for prey density.
+Moreover, the following three questions may be used as guidelines for exploring this situation:
+  * What is the indirect effect of pollinator density on prey density?
+  * Can a carnivorous plant population survive only relying on pollinators for both reproductive and nutritional purposes?
+  * Investigate the effects of the mechanisms carnivorous plants may employ to resolve these conflicts. For instance, you may assume that during the phenological cycle of the plant there is a marked reproductive phase where flowers are produced and traps are supressed, thus inducing temporal segregation between flowers and traps.
