 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. Insectivorous plants benefit from trapped, dead insects as a source of nutrients.

 Nonetheless, even in the presence of such traits, potential pollinators may end trapped by their mutualistic partners. Nonetheless, even in the presence of such traits, potential pollinators may end trapped by their mutualistic partners.

 +  * 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. 
  
-  * Investigate the effects of the mechanisms carnivorous plants may employ to resolve these conflicts. For temporal segregation, you may consider some phase lag between flower and trap development. For spatial or chemical segregation, you may consider that this segregation is mediated by some phenotypic trait in the carnivorous plant population (for instance, the distance between flowers and traps). +===== References =====
