The objective of this study was to apply phospholipid fatty acid (PLFA)-based stable isotope probing to assess the temporal variation of active microorganisms associated with rhizosphere-C flow in a natural wetland. We applied 13CO2 pulse labeling at three different times throughout the vegetation period: spring (April), early summer (June), and early(More)
Radar remote sensing has shown its potential for retrieving soil moisture from bare soil surfaces. Since the backscattering process is also determined by the soil roughness , the characterisation of the roughness is crucial for an accurate soil moisture retrieval. However, several field experiments have shown a large variability of the roughness parameters.(More)
—It is widely recognized that Synthetic Aperture Radar (SAR) data are a very valuable source of information for the modeling of the interactions between the land surface and the atmosphere. During the last couple of decades, most of the research on the use of SAR data in hydrologic applications has been focused on the retrieval of land and biogeophysical(More)
