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 ...
Habitat relationships and habitat variability of the wood warblers (Parulidae)
(1981)
Based on 13 structural variables, the habitat structure of 16 species of wood warblers breeding in north-central Minnesota can be divided into three general habitat types: open country, shrub-forest edge, and mature forest. ...
Remote sensing analysis of croplands, woody plant encroachment and carbon fluxes of woody savanna
(2017-05-12)
Since 1990s, much attention has been paid to Land use/land cover change (LULCC) studies because it is an important component of global change. The vegetation change is a critical factor of land cover changes, which interacts ...
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 ...
Responses of a tallgrass prairie to experimental warming.
(2002)
I also examined the potential responses of C and N processes to elevated temperature. The results suggest that there was a time lag between the response of peak aboveground biomass (AGB) and that of net N mineralization. ...
Plant competition theory: Empirical tests from the tallgrass prairie.
(1997)
Depending upon the parameter and scale of measurement, evidence for each model exists. Further studies of "natural" resource and disturbance regimes (e.g, fire, urine patches, grazing) with greater temporal complexity are ...
Description and dynamics of some western oak forests in Oklahoma.
(1983)
Ordination and classification techniques were used to analyze patterns of forest vegetation, species diversity and soil type in the Wichita Mountains Wildlife Refuge. Cluster analysis based on species composition of the ...
