Elevated Carbon Dioxide Stimulates Net Accumulations of Carbon and Nitrogen in Terrestrial Ecosystems: A Meta-Analysis
نویسندگان
چکیده
The capability of terrestrial ecosystems to sequester carbon (C) plays a critical role in regulating future climatic change yet depends on nitrogen (N) availability. To predict long-term ecosystem C storage, it is essential to examine whether soil N becomes progressively limiting as C and N are sequestered in long-lived plant biomass and soil organic matter. A critical parameter to indicate the long-term progressive N limitation (PNL) is net change in ecosystem N content in association with C accumulation in plant and soil pools under elevated CO 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18

متن کاملStimulation of terrestrial ecosystem carbon storage by nitrogen addition: a meta-analysis.
Elevated nitrogen (N) deposition alters the terrestrial carbon (C) cycle, which is likely to feed back to further climate change. However, how the overall terrestrial ecosystem C pools and fluxes respond to N addition remains unclear. By synthesizing data from multiple terrestrial ecosystems, we quantified the response of C pools and fluxes to experimental N addition using a comprehensive meta-...
متن کاملLong-Term CO2 Stimulation of Carbon Influx Into Global Terrestrial Ecosystems: Issues and Approaches
Estimating the additional amount of global photosynthetic arbon influx into terrestrial ecosystems (PG) becomes possible with a leaf-level factor (Y) developed by Luo & Mooney only when an increase in atmospheric CO2 concentration (Ca) is small. Applying the Y factor to study long-term stimulation of PG with a large increase in Ca needs understanding of adjustments in leaf properties, canopy st...
متن کاملCarbon-Nitrogen Interactions in Terrestrial Ecosystems in Response to Rising Atmospheric Carbon Dioxide
Interactions involving carbon (C) and nitrogen (N) likely modulate terrestrial ecosystem responses to elevated atmospheric carbon dioxide (CO2) levels at scales from the leaf to the globe and from the second to the century. In particular, response to elevated CO2 may generally be smaller at low relative to high soil N supply and, in turn, elevated CO2 may influence soil N processes that regulat...
