Focus: Climate change and invertebrates

Investigating the impacts of global climate and atmospheric change on terrestrial invertebrates is one of our key research areas. We use a diverse array of platforms including EucFACE and DRI-Grass in addition to conventional glasshouses and cabinets.

Much of our recent climate change research now involves plant silicon.
