The important role of fire in regulating vegetation community composition and contributions to emissions of greenhouse gases and aerosols make it a critical component of dynamic global vegetation models and Earth system models. Over 2 decades of …
In this dissertation, I explore the role that agricultural fire management plays in global patterns of vegetation fire and thus carbon cycling between ecosystems and the atmosphere. No estimates previously existed of the amount of fire associated …
Fire regimes in savannas and forests are changing over much of the world. Anticipating the impact of these changes requires understanding how plants are adapted to fire. In this study, we test whether fire imposes a broad selective force on a key …
Biomass burning impacts vegetation dynamics, biogeochemical cycling, atmospheric chemistry, and climate, with sometimes deleterious socio-economic impacts. Under future climate projections it is often expected that the risk of wildfires will …
The global extent of agriculture demands a thorough understanding of the ways it impacts the Earth system through the modification of both the physical and biological characteristics of the landscape as well as through emissions of greenhouse gases …
The timing and length of burning seasons in different parts of the world depend on climate, land-cover characteristics, and human activities. In this study, global burned area estimates are used in conjunction with global gridded distributions of …
