	abstract = {<p>Human activities are transforming grassland biomass via changing climate, elemental nutrients, and herbivory. Theory predicts that food-limited herbivores will consume any additional biomass stimulated by nutrient inputs ({\textquoteright}consumer-controlled{\textquoteright}). Alternatively, nutrient supply is predicted to increase biomass where herbivores alter community composition or are limited by factors other than food ({\textquoteright}resource-controlled{\textquoteright}). Using an experiment replicated in 58 grasslands spanning six continents, we show that nutrient addition and vertebrate herbivore exclusion each caused sustained increases in aboveground live biomass over a decade, but consumer control was weak. However, at sites with high vertebrate grazing intensity or domestic livestock, herbivores consumed the additional fertilization-induced biomass, supporting the consumer-controlled prediction. Herbivores most effectively reduced the additional live biomass at sites with low precipitation or high ambient soil nitrogen. Overall, these experimental results suggest that grassland biomass will outstrip wild herbivore control as human activities increase elemental nutrient supply, with widespread consequences for grazing and fire risk.</p>

	abstract = {<p>Soil nitrogen mineralisation (N), the conversion of organic into inorganic N, is important for productivity and nutrient cycling. The balance between mineralisation and immobilisation (net N) varies with soil properties and climate. However, because most global-scale assessments of net N are laboratory-based, its regulation under field-conditions and implications for real-world soil functioning remain uncertain. Here, we explore the drivers of realised (field) and potential (laboratory) soil net N across 30 grasslands worldwide. We find that realised N is largely explained by temperature of the wettest quarter, microbial biomass, clay content and bulk density. Potential N only weakly correlates with realised N, but contributes to explain realised net N when combined with soil and climatic variables. We provide novel insights of global realised soil net N and show that potential soil net N data available in the literature could be parameterised with soil and climate data to better predict realised N.</p>
