change in precipitation, nitrogen deposition, and land-use change have the potential to significantly affect future stocks of soil organic carbon (SOC). These factors, individually or by interacting with each other, can also trigger positive or negative feedback to the processes affecting the rate ...
This study challenges the hypothesis that high-quality plant litters form stable, mineral-associated soil organic carbon most efficiently, providing evidence that litter-microbial interactions and soil mineralogy regulate soil organic carbon formation. ...

A progressive trend towards heavier δ13C values of Devonian-Mississippian brachiopods from North America, Europe, Afghanistan and Algeria probably reflects expansion of the terrestrestrial and/or marine biomass and/or burial of carbon in soils/sediments. Oceanic Productivity crises, based on perturbatio...

Stable carbon isotopes and PhyloChip gene hybridization analyses were done on groundwater samples. Microbes from the FTSIR co-metabolically degraded approximately 7.5 mg of TCE per liter of groundwater. Proteins from aerobic methanotrophs were detected in the aquifer and on the basalt from the FTISR...

The search was limited to the following keywords to clearly indicate the main focus of our paper: temperate forests, carbon and nitrogen isotopes, litter decomposition, and SOM. Even in references, we excluded results from non-temperate forest sites and indoor experiments that used agricultural ...
