Possible impacts of global warming on tundra and boreal forest ecosystems: Comparison of some biogeochemical models
International audience Global warming affects the magnitude of carbon, water and nitrogen fluxes between biosphere and atmosphere as well as the distribution of vegetation Types. Biogeochemical models, global as well as patch models, can be used to estimate the differences between the mean values of...
