Rivers are an important component of the global carbon cycle and contribute to atmospheric carbon exchange disproportionately to their total surface area. Largely, this is because rivers efficiently mobilize, transport and metabolize terrigenous organic
Drought level definition based on PAI. Because of difficulty to evaluate absolute droughts, the meteorological drought level was used to estimate the drought severity. Table 1 shows the relationship between the PAI and meteorological drought level in three temporal scales...
Unravelling biosphere feedback mechanisms is crucial for predicting the impacts of global warming. Soil priming, an effect of fresh plant-derived carbon (C) on native soil organic carbon (SOC) decomposition, is a key feedback mechanism that could release
