Disturbance & Recovery Across Global Grasslands
DRAGNet is a distributed experiment that assesses the generality of factors influencing responses to disturbance in herbaceous-dominated ecosystems. This network spans over 60 sites in grasslands worldwide to examine theoretically-motivated questions about the effects and interactions of two pervasive global changes: land disturbance and nutrient supply. Primary goals include:
Quantify resistance to, and recovery from, soil disturbance across a wide variety of grasslands under ambient and elevated nutrient supply.
Assess the reproducibility of ecological experiments using data from sites that participate in both NutNet and DRAGNet and started nutrient addition treatments in different years.
Determine the relative importance of local and regional processes for community assembly by pairing theoretical models with plant, seed bank, and seed rain data.
