“Changes in soil bacterial community: diversity, composition and function triggered by drought-induced gap succession preceded changes in soil C stocks and quality ” Curiel-Yuste J., Barba J., Fernandez-Gonzalez A.J., Fernandez-Lopez M., Mattana S., Martinez-Vilalta J., Pau Nolis, Lloret F. Ecology and Evolution. Accepted 2012.
We investigated soil bacterial taxonomic composition, soil respiration and soil organic matter quantity and quality in a mixed Mediterranean forest where the Scots pine (Pinus sylvestris) population is affected by climatic drought-induced die-off, and replaced by Holm-oak (Quercus ilex) populations as the dominant tree species.

Dynamic Nuclear Polarization is the method for obtaining strongly polarised nuclear spins, resulting in enhanced NMR signals for 13C and 15N nuclei in solution-state
Our NMR facility (SeRMN) has recently installed a HyperSense® (Oxford Instruments), a new instrument capable of delivering a huge sensitivity enhancement for your in-vitro and in-vivo applications allowing an easy and quick switching between both applications.
Liquid-state NMR spectroscopy is an important technique into a wide range of applications. However, it is limited by an intrinsically lack of sensitivity due to the low gyromagnetic ratio and natural abundance of the nuclei usually under study (13C, 15N, etc.) as compared with other analytical methods.
