- 摘要：
- , conservation without elephants and communal rangelands) across a rainfall gradient in South African savannas. Different directions of woody cover change would
Data from: Woody cover in wet and dry African savannas after six decades of experimental fires

- 摘要：
- n the dry savanna. In the dry savanna, fire was more effective in greatly increasing coppicing in trees, when compared to the wet savannas. 4. Synthesis
Data from: The future distribution of the savannah biome: model-based and biogeographic contingency
- 负责人：
- DOI：
- doi:10.5061/dryad.4mm12
- 摘要：
- projections are given when using different modelling approaches to estimate future distributions. Furthermore, biogeographic variation within savannas in plant

- 摘要：
- also strongly affects tree cover. However, in African savannas and forests, harvest of trees by humans for cooking and heating is an oft overlooked
Data from: The mesic savannas of the Bateke Plateau: carbon stocks and floristic composition

- 摘要：
- to other African savannas, is surprising considering the high rainfall. We speculate it is due to low nutrient soils, high fire frequency and the effect
Data from: The present and future effects of land use on ecological assemblages in tropical grasslands and savannas in Africa
- 负责人：
- DOI：
- doi:10.5061/dryad.qs1k6
- 摘要：
- l grasslands and savannas under land-use change. We show that ecological assemblages are affected more by land use in African grasslands and savannas than in other biomes

- 摘要：
- Savannas are widespread global biomes covering ~20% of terrestrial ecosystems on all continents except Antarctica. These ecosystems play a critica
Data from: Seedling growth of savanna tree species from three continents under grass competition and nutrient limitation in a greenhouse experiment

- 摘要：
- -grass patches. 2. We compared seedlings of 40 tree species sampled from humid and semi-arid savannas of three continents (Africa, Australia, South America
Data from: A stoichiometric perspective of the effect of herbivore dung on ecosystem functioning

- DOI：
- doi:10.5061/dryad.3sq24
- 摘要：
- Ungulate herbivores play a prominent role in maintaining the tree–grass balance in African savannas. Their top-down role through selective feeding
Data from: Competitive response of savanna tree seedlings to C4 grasses is negatively related to photosynthesis rate

- 摘要：
- competitive asymmetry. Our results identify a potentially important trade-off that enhances our ability to predict how savanna tree communities might respond
