Ecosystem Greenhouse Gas Fluxes and Carbon Dynamics

Terrestrial ecosystems such as forests, wetlands, grasslands, shrublands, croplands and tundra play an important role in mitigating the effects of greenhouse gases by efficiently removing atmospheric carbon. However, climate change mitigation benefits have to be achieved through maintenance, conservation and restoration. This research aims to discover the patterns and scaling laws of ecosystems and formulate models to predict the exchange of carbon.
