2010/1/21
Numerous recent studies have indicated that dissolved organic carbon (DOC) and nitrogen (DON) play an important role in C and N cycling in natural ecosystems, and have shown that N deposition alters t...
Nitrogen deposition, catchment productivity, and climate as determinants of lake stoichiometry
Nitrogen deposition catchment productivity climate as determinants of lake stoichiometry
font style='font-size:12px;'>
2014/4/17
Nearly 1000 Norwegian lakes in catchments with low human activity were surveyed. By covering a wide range of nitrogen (N) deposition (0.1-2 g m-2 yr-1) along a latitudinal and climatic gradient, we cl...
Modelling the ecosystem effects of nitrogen deposition：Model of Ecosystem Retention and Loss of Inorganic Nitrogen
