By using stable isotope labelling and natural abundance approaches, I conduct research to:
1) explore how forest ecosystems respond to global environmental changes, e.g., N deposition and global warming;
2) reveal tree growth and N cycling in the past 200 years;
3) quantify nitrogenous gas losses and the contribution of microbial processes from terrestrial ecosystems soils;
4) examine plants plasticity and link them to plant biodiversity.
