Above-ground - below-ground trophic interactions

There is now emerging consensus that above-ground and below-ground compartments are intimately linked, with many examples of spatially separated organisms interacting to shape community dynamics via plant-mediated mechanisms. Research at SCRI aims to gain a mechanistic understanding of the genetic and chemical plant-mediated processes which underpin interactions between organisms that exploit different parts of the plant. By understanding these key processes, we aim to exploit natural resistance mechanisms to herbivore attack and manipulate trophic interactions to manage crop pests and maintain system stability.

We work on several systems including barley, raspberry and brassicas, focusing on how soil-dwelling herbivores (predominantly root-feeding insects) affect above-ground herbivores, their antagonists (for example, parasitoids) and plant pathogens. At present our experimental and modelling research is funded by the Scottish Government, the Natural Environmental Research Council and the Engineering and Physical Sciences Research Council. Examples of our current research include the following.Image of aphids
