My main interest is researching processes of environmental change and how these are registered by tropical vegetation, how this may respond in a future of uncertain change and how we can use such information to guide appropriate policy development. My research covers the fields of biogeography, ecology, palaeoecology and ecosystem modelling. Combining these disciplines I develop an understanding, at an ecologically sensible timeframe, of the events that have shaped the past, present and future composition and distribution of tropical ecosystems.
Climate dynamics impact on tropical ecosystems have a global signal understanding the phase relationships of how ecosystems respond to these large scale processes is vital for a considered insight into understanding the spatial pattern and associated impacts of future climate change. We need to explore the relationship between ecosystem dynamics, climate change, and human impacts in Africa if we are to truly manage their sustainable futures.
