Herbaceous biomass–species diversity relationships in nutrient hotspots of a semi-arid African riparian ecosystem
Item type: Journal Article • Journal: African Journal of Range & Forage Science • Authors: Helga van Coller --- Unit of Environmental Sciences and Management, South Africa Frances Siebert --- Unit of Environmental Sciences and Management, South AfricaThe hump-back relationship between species diversity and productivity predicts highest species richness at intermediate levels of biomass, and low species numbers in least and most productive habitats. Sodic patches of semi-arid savannas are considered ‘nutrient hotspots’ by producing high-quality forage...
