Wind Shifts May Stir CO2 From Antarctic Depths--Releases May Have Speeded End of Last Ice Age—And Could Act Again（图）
Wind Shifts CO2 Antarctic Depths Last Ice Age
2009/12/10
Natural releases of carbon dioxide from the Southern Ocean due to shifting wind patterns could have amplified global warming at the end of the last ice age--and could be repeated as manmade warming pr...
Relative stability of soil carbon revealed by shifts in δ15N and C:N ratio
Relative stability soil carbon shifts δ15N C:N ratio
2010/1/15
Life on earth drives a continuous exchange of carbon between soils and the atmosphere. Some forms of soil carbon, or organic matter, are more stable and have a longer residence time in soil than other...
Community shifts and carbon translocation within metabolically-active rhizosphere microorganisms in grasslands under elevated CO2
Community shifts carbon translocation metabolically-active rhizosphere microorganisms
2010/1/14
The aim of this study was to identify the microbial communities that are actively involved in the assimilation of rhizosphere-C and are most sensitive in their activity to elevated atmospheric CO2 in ...
