Research project

For my master's thesis, I am interested in the interaction between one plant and their pollinators. In particular, the interaction between bees populations and the birdsfoot trefoil (Lotus corniculatus).

It has been shown that pollen from this flower species can be toxic to some bee larvae species. Indeed, the trefoil produces cyanogenic compounds (linamarine and lotaustraline). The question is whether the plant produces these chemicals in pollen or whether it is simply the flow of the compounds through the plant and therefore there is a correlation in the concentration of these secondary compounds between different parts of the plant.

My project will investigate the effect of altitudinal variation on cyanogenic compounds in different parts of the plant and on the influence of cyanogenic compound content on pollinator communities.

Main topics

  • Plants-insects interaction
  • Cyanogenic glycosides
  • Chemical ecology
  • Lotus corniculatus
