Here, we present an on-field, real-time, high-frequency measurements of δ 13 C and isotopically partitioned NEE. We were able to detect seasonal and diel differences in isotopically partitioned fluxes, source of autotrophic fraction in daytime respiration, and limitation in standard estimation to identify stomatal conductance under water stress. St...

The growth dynamics of above- versus belowground tissues, i.e. carbon allocation, affect the forests’ ability to cope with environmental stresses and may affect their ability to mitigate and adapt to climate change. While aboveground growth dynamics have been well documented, the belowground growth, growth efficiency, and relationship to abovegroun...

Long-term trends in riverine nutrient availability have rarely been linked to both phytoplankton composition and functioning. To explore how the changing availability of N and P affects not only phytoplankton abundance and composition but also the resource use efficiency of N, P, and CO2, a 25-year time series of water quality in the lower Han Rive...

Although eutrophic urban rivers receiving loads of wastewater represent an important anthropogenic source of N2O, little is known as to how temperature and other environmental factors affect temporal variations in N2O emissions from wastewater treatment plants (WWTPs) and downstream rivers. Two-year monitoring at a WWTP and five river sites was com...

Wastewater may alter riverine fluxes of dissolved organic matter (DOM) and CO2, yet little is known about how treated and untreated wastewater affects riverine DOM biodegradation and CO2 emission to a different degree. In order to compare effects of treated vs untreated wastewater on DOM biodegradation and CO2 emission in downstream rivers, a three...
