OXYEVOL: The role of atmospheric oxygen in plant evolution over the past 400 million years

Oxyevol logo

ERC logoHow did changes in atmospheric O2 and CO2 concentration influence the timing of key evolutionary innovations and shifts in ecological dominance/success of various plant groups throughout geological time?

Biome-level vegetation response to future global change: implications for future flood risk

Oxyevol logo

SFI logoInvestigate how plant functional traits and leaf anatomy can be used to improve global climate models to predict future flood risk and to  reconstruct past climatic events.
