Variability in fire-induced change to vegetation physiognomy and biomass in semi-arid savanna

Fire plays an intrinsic role in shaping the biophysical attributes of savanna ecosystems. Savanna fires limit vegetation biomass below their climatically determined potential, but the magnitude of this effect and how it varies across heterogeneous …

Habitat differences do not explain population declines of sable antelope in an African savanna

Sable antelope, Hippotragus niger, populations have declined substantially in Kruger National Park, South Africa despite large-area protection from land use and poaching. Since Africa's large mammal populations are restricted to protected areas, …

Large-scale impacts of herbivores on the structural diversity of African savannas
