My research focuses on how shared evolutionary history shapes species’ interactions, and how such interactions influence species level & community responses to environmental change. Here community and population level consequences of mutualistic & antagonistic interactions with keystone species are particularly informative. I am considering their adaptive backgrounds as local adaptation or phylogeographic histories and how these affect associated communities of parasites/herbivores and their parasitoid natural enemies. Examples include the ecology and evolution of social parasites in ant societies and determinants of community structure and community dynamics of herbivorous insects on oak and their associated parasitoids. Lately have included the microbiota of the foundation species and investigate how their communities are shaped by the genetic background of their host (= the extended phenotype) and how their communities might affect interactions with the higher trophic levels.
I have been focussing on two study systems: (1) trees their associated herbivores and their natural enemies and (2) ants and their social parasites. In both I assess their adaptive potential and the impact on the wider community particularly in relation to Climate Change and community resilience to environmental change. My current work considers tree microbomes in the context of tree health (e.g. Red Needle Blight, Scots Pine & Acute Oak Decline)
In a separate line of research I continue studies of biological invasions and the post-invasion recruitment of natural enemies. Our current focus is the Oriental Chestnut Gallwasp that is well established in the Mediterranean and was recently recorded from the UK. I have been involved in horizon scanning exercises for the UK and the EU and have worked on minimum standards of risk assessments for invasives.
