Nitrogen cycling and dynamics in a macrophyte-rich stream
1. A N-NH4 tracer release study was conducted in a macrophyte-rich stream, the River Lilleaa in Denmark. The objectives of the study were to compare uptake rates per unit area of NH4 by primary producers and consumers in macrophyte and non-macrophyte habitats, estimate wholestream uptake rates of NH4 and compare this to other stream types, and identify the pathways and estimate the rate at whic...
متن کاملModeling soil microbial dynamics in carbon and nitrogen cycling
Goal To determine the relative importance of different mechanisms that influence carbon loss from soil under variable soil-moisture conditions. The soil contains more carbon than the atmosphere and plants combined (Scurlock and Hall 1998). This carbon is important for maintaining soil fertility, controlling erosion, and the long-term storage of carbon that could be released into the atmosphere....
متن کاملLiquid chromatography/mass spectrometry stable isotope analysis of dissolved organic carbon in stream and soil waters.
A commercial interface coupling liquid chromatography (LC) to a continuous-flow isotope ratio mass spectrometry (CF-IRMS) instrument was used to determine the δ(13) C of dissolved organic carbon (DOC) in natural waters. Stream and soil waters from a farmland plot in a hedgerow landscape were studied. Based on wet chemical oxidation of dissolved organics the LC/IRMS interface allows the on-line ...
متن کاملLC/MS stable isotope analysis of dissolved organic carbon in stream and soil waters
A commercial interface coupling liquid chromatography (LC) to a continuous-flow isotope ratio mass spectrometer (IRMS) was used to analyse δ 13 C of dissolved organic carbon (DOC) in natural waters. Stream and soil waters from a farmland plot in a hedgerow landscape were selected for application. Based on wet chemical oxidation of dissolved organics the LCIRMS interface allows on-line injection...
متن کاملSoil Nitrogen Dynamics in Organic and Mineral Soil Calcareous Wetlands in Eastern New York
C of wetlands is often highly problematic due to the need to consider soil, plant, and Calcareous wetlands are of great interest in conservation biology. Previous research has suggested that there are significant differences hydrologic factors as fundamental components of these in soil microbial N cycle processes between calcareous wetlands develecosystems (Bridgham et al., 1996). The term wetl...
