IMPROVING GLOBAL CARBON CYCLE MODELS WITH OBSERVATIONS
(2014-05)
In the future warming world terrestrial ecosystems may mitigate increasing temperatures by sequestering CO₂ from the atmosphere, or they can intensify future global change, amplifying the rate of CO₂ production in response ...
Anaerobic reduction of hexavalent chromium by subsurface microorganisms.
(1999)
Anaerobic sediments from an aquifer contaminated with landfill leachate were used to study the potential for microbial reduction of Cr(VI) to Cr(III). The lightly colored, sandy sediments slowly reduced Cr(VI) in viable, ...
Responses of soil respiration and ecosystem productivity to climate change in southern Great Plains.
(2007)
The third is to investigate the role of precipitation on ecosystem carbon processes (i.e., biomass, litterfall, and soil respiration) along a natural precipitation gradient in southern Great Plains. Our results show that ...
The ecology and biogeochemistry of sulfate reduction in the terrestrial subsurface.
(1999)
I believe that the ubiquity and importance of sulfate reduction in subsurface environments is a reflection of the diversity of the hydrological and biogeochemical processes which contribute to the availability of sulfate. ...
Experimental and modeling studies of canopy radiation and water use efficiencies, soil respiration and net ecosystem carbon exchange.
(2002)
Canopy radiation and water use efficiencies (RUE and WUE), soil respiration and interannual availability in net ecosystem carbon exchange (NEE) are important issues in global climate change study. This thesis summarized ...
Interactions between ecosystem carbon, nitrogen and water cycles under global change: Results from field and mesocosm experiments.
(2005)
N additions increased NEE by enhancing light interception, RUE, and extending growing seasons. Different N application methods (PF versus GF) caused differential seasonal dynamics of LAI, NEE and RUE due to their different ...
