Evaluating impacts of hydroclimatic extremes on water use efficiency and carbon use efficiency of northern ecosystems
… ecosystems. As essential global water and carbon balance regulators, these sensitive ecosystems respond to increased warming and altered hydrology with modulated resource use efficiencies. This study aimed to investigate the impacts of various hydroclimatic drivers on ecosystem Water Use …

Corticular Photosynthetic Dynamics for a Coastal Evergreen Shrub: Myrica Cerifera
… photosynthesis contributes to whole plant carbon gain by reducing respirational CO2 loss. Maximum % refixation was 110 ± 39 % of CO2 efflux in the dark (Rd) in 1st order branches during winter, minimum was 18 ± 3 % in 5th order branches during summer. Variations in % refixation paralleled …

The response of grassland carbon cycling to drought events and changes in nutrient availability
… services, including agricultural production, carbon (C) storage and nutrient cycling. In particular, climate change is likely to increase the frequency and severity of extreme climate events, such as drought and the subsequent rewetting event. Yet the effect of drought events will not be …

Quantifying biophysical and biogeochemical influence on northern high latitudes greenhouse gases dynamics
… on northern high latitudes (NHLs) greenhouse gases (GHGs) emission in a terrestrial modeling framework. To achieve this objective, I extended and calibrated a land surface model, the Integrated Science Assessment Model (ISAM), to explore how the physical and chemical interactions within …
