The principal drivers of Grassland Biome conversion and degradation in South Africa
include agricultural intensification, plantation forestry, urban expansion and mining, together …

Human activities are enriching many of Earth's ecosystems with biologically limiting mineral
nutrients such as nitrogen (N) and phosphorus (P). In grasslands, this enrichment generally …

Terrestrial ecosystems have experienced rising nitrogen (N) inputs during the last decades
with consequences for belowground carbon (C) and N dynamics. This study investigates …

The soil under savanna woody species is often enriched in nutrients in what is termed an
'island of fertility'. We tested for positive feedbacks between encroaching woody plants and …

The relationship between soil microbial communities and enzymes on the nutrient dynamics
in phosphorus (P) deficient grassland ecosystem soils of KwaZulu-Natal province, South …

Nitrogen (N) and phosphorus (P) nutrient enrichment is important for grasslands. This study
aimed to determine how soils enriched with N and P influenced soil concentration …

Soil respiration is often used as an index of fertility because the majority of nutrients are
cycled through the microbial biomass. We assessed the role of soil respiration as a measure …

Net primary productivity (NPP) in global grasslands is a critical component of terrestrial
carbon cycling and the primary source of food for herbivores. However, the size and spatial …

Radical veld improvement (RVI), a concept explored in southern Africa during the mid to late
1900s, aimed to intensify agricultural landscapes by enhancing veld productivity by …

Background One key approach for anticancer therapy is drug combination. Drug
combinations can help reduce doses and thereby decrease side effects. Furthermore, the …
