My general interest is predicting vegetation dynamics at the global scale, based on information about climate and other controlling factors.
Currently, I am trying to find out which factors determine the global distribution of vegetation on the ground (e.g. mosses). This may be important, for instance, at high latitudes, where vegetation at the ground acts as an insulating layer for the frozen soil below (permafrost). If the soil warms up due to a reduction in vegetation, considerable amounts of CO2 may be released which would further enhance global warming.
As a tool to make these predictions I use numerical models which represent the complex processes and interactions associated with global vegetation in a simplified way. The modelling approach can be extended to simulate further aspects of global moss vegetation, such as patterns of biodiversity or the impact of moss on global weathering rates.
