Application of ABB LGR water isotope analyzer on the partitioning of catchment evapotranspiration fluxesEvapotranspiration (ET) is an important process in the water budget of an ecosystem. Quantifying the components (Esoil and T)) of evapotranspiration is of great significance in revealing the ecohydrological process of alpine inland river basins. At present, the research on Esoil and T is mainly based on the observation site scale to calculate local evapotranspiration components, there are few reports on the changes of evapotranspiration components at the watershed scale. Hydrogen and oxygen ...

Arbuscular mycorrhizal fungi alleviate elevated temperature and nitrogen deposition- induced warming potential by reducing soil N2O emissions in a temperate meadowNitrous oxide (N2O) is one of the most important greenhouse gases and plays an important role in global warming (IPCC, 2013). N2O emissions contribute nearly 10% of anthropogenic climate warming because of their higher global warming potential. The emission of N2O has been influenced by many global changes, including elevated temperature, drought, and nitrogen (N) deposition. Arbuscular mycorrhizal (AM) fungi form mutualist...

Soil CO2 and CH4 emissions and their carbon isotopic signatures linked to saturated and drained states of the Three Gorges Reservoir of ChinaIncreased CO2 and CH4 emissions are the main causes of global warming (IPCC, 2013), with approximately 44% and 60% of CO2 and CH4 emissions being emitted into the atmosphere by anthropogenic activities. Human activities such as dams disturb the structure and function of wetlands, triggering large soil CO2 and CH4 emissions. However, controls over field CO2 and CH4 emissions and their carbon isotopic signatures in reservoir wetlands are not yet fully under...

Chenghai Lake BasinShrinkage of plateau lakes under climate strength has drawn growing attention. Because of its intricate implication to hydro-meteorological condition and climate system, stable isotopes in precipitation (e.g. δ2Hp and δ18Op) provide us a powerful tool to understand the climate-hydrologic dynamics in shrinking lakes. Most studies, however, focused on either the impact of large-scale atmosphere circulation and moisture sources or the local isotopic fractionation processes. So far, limited study has yet been carried out on the combined effect of both the regional atmospheric ci...

Application of ABB LGR CCIA on tracking the spatio-temporal fate of 13C-labelled assimilates in the soil of an old-growth pine forestWater is essential for all organisms and thus, the increasing intensity and frequency of drought in large areas of the Northern hemisphere is impacting the diversity and functioning of forest ecosystems. Impacts of drought on ecosystems range from immediate reductions of the metabolic activity of plants and soil organisms and the acclimation of physiological processes to species shifts under prolonged or reoccurring drought. The interrelation of different ecosyst...
