Journal ArticleDOI
Assessing the vulnerability of species richness to anthropogenic climate change in a biodiversity hotspot
TL;DR: In this paper, the authors compared theoretical approaches towards estimating risks of plant species loss to anthropogenic climate change impacts in a biodiversity hotspot, and developed a practical method to detect signs of climate change impact on natural populations.
Journal ArticleDOI
The importance of low atmospheric CO2 and fire in promoting the spread of grasslands and savannas
TL;DR: In this article, a dynamic global vegetation model (DGVM) was used to simulate biomass in grassy ecosystems in South Africa with and without fire and the results indicated that fire has a major effect under higher rainfall conditions suggesting an important role for fire/[CO2] interactions.
Journal ArticleDOI
Specific Leaf Area and dry Matter Content Estimate thickness in Laminar Leaves

TL;DR: Leaf thickness can be estimated by (SLA x LDMC)(-1), allowing leaf thickness to be derived from easily and widely measured leaf traits.
Journal ArticleDOI
Carbon dioxide and the uneasy interactions of trees and savannah grasses
William J. Bond,Guy F. Midgley +1 more
TL;DR: Diverse tests of the magnitude of CO2 effects on both ancient and modern ecosystems with a particular focus on African savannahs are reported on, finding large increases in trees of mesicsavannahs in the region cannot easily be explained by land use change but are consistent with experimental and simulation studies ofCO2 effects.
Journal ArticleDOI
What controls South African vegetation — climate or fire?
TL;DR: In this paper, the relative importance of fire and climate in determining ecosystem characteristics was tested by simulating potential vegetation of South Africa with and without fire using a Dynamic Global Vegetation Model (DGVM).
