Introduction
I am interested in evolutionary ecology and how the Savanna Biome may be formed through plant-plant competition over deep evolutionary timescales. What lurks behind fire, herbivores, and drought?

The coexistence of leguminous trees and C4 grasses in African savanna remains poorly understood. Trees are able to establish among grasses despite grasses being competitively superior for below ground resources. Here we test the hypothesis that trees are only able to establish when grass biomass has been reduced. We do this at four locations in Lim...
Globally there is increasing concern over the biodiversity and economic losses associated with bush encroachment. The dominant species responsible for bush encroachment in Africa belong to the mimosoid genera Senegalia and Vachellia, with previous research identifying Vachellia as the more aggressive invader. We asked whether these genera have evol...
