Disturbance, Functional Diversity and Ecosystem Processes: Does Species Identity Matter?
… on vegetation dynamics, physicochemical soil properties, and ecosystem processes. Additionally, plant functional diversity has been suggested as the key to ecosystem processes such as productivity and nutrient dynamics. I investigated how disturbance and functional composition both singly …

Carbon fluxes at an upland blanket bog in the north Pennines
The peat soils found in blanket bogs are significant stores of carbon. The degree to which these ecosystems are currently functioning as sinks or sources of carbon is not clear. There is a paucity of measurements from suitable sites but the available evidence suggests that certain sites might be …

Spatial and temporal variation In greenhouse gas flux as affected by mowing on grasslands of hummocky terrain In Saskatchewan
… of topography and mowing on carbon dioxide (CO2), methane (CH4) and nitrous oxide (N2O) flux and to correlate them with environmental and plant community characteristics. The study site was located in the Northern Mixedgrass Prairie of the Missouri Coteau near Macrorie, SK. April mowing and …

Heat transfer, evaporation and carbon dioxide transfer in soil
<p>Latent heat flux associated with soil water evaporation connects the surface water balance with the surface energy balance. Soil water evaporation and soil carbon dioxide (CO2) fluxes both involve soil gas transport processes and properties, and both impact the soil environment and physical, …

The Effect of Prescribed Burning on Soil Microbial Communities, Nutrients, and Carbon Dioxide Fluxes Under and Between Sagebrush Canopies in the Semi-Arid Rangelands of Northern Nevada
… to cause immediate and long-term changes to soil microbial communities, nutrient dynamics, and carbon dioxide (CO2) fluxes. These changes can have direct and indirect effects on soil biochemistry and respiration. The effects of fire on soil largely depend on time and seasonality, frequency, …
