Chemical communication by trees

Thesis defence
Trees communicate: they warn each other, attract pollinators, and daunt enemies. This happens through chemical compounds called BVOCs. Ylva van Meeningen has studied the importance of the genetic diversity in the production of BVOCs, and the communication of trees.

That BVOCs affect our climate is quite well known, by changing the chemical properties of the atmosphere. But there are variations in how trees release them, both between individuals of the same species and between species, which make it difficult to decide how much and in what way the climate is affected.

Ylva van Meeningen has been travelling through Europe to look at genetically identical trees of the same species, at different locations along a latitudinal gradient. With this she aims to answer this question: is it the genetic material or the location that is more important?

Thesis title: Is genetic diversity more important for terpene emissions than latitudinal adaptation? : Using genetically identical trees to better understand emission fluctuations across a European gradient.
