  • Nitrous oxide nitrification and denitrification 15N enrichment factors from Amazon forest soils 

    Perez, Tibisay; Garcia-Montiel, Diana; Trumbore, Susan E.; Tyler, Stanley; de Camargo, Plinio; Moreira, Marcelo; Piccolo, Marisa C.; Cerri, Carlos C. (Ecological Society of America, 2006-12)
    The isotopic signatures of 15N and 18O in N2O emitted from tropical soils vary both spatially and temporally, leading to large uncertainty in the overall tropical source signature and thereby limiting the utility of isotopes ...
  • Soil respiration at mean annual temperature predicts annual total across vegetation types and biomes 

    Bahn, Michael; Reichstein, M.; Davidson, Eric A.; Grunzweig, J.; Jung, M.; Carbone, M. S.; Epron, D.; Misson, L.; Nouvellon, Y.; Roupsard, O.; Savage, K.; Trumbore, Susan E.; Gimeno, C.; Curiel Yuste, J.; Tang, Jianwu; Vargas, Rodrigo; Janssens, Ivan A. (Copernicus Publications on behalf of the European Geosciences Union, 2010-07-09)
    Soil respiration (SR) constitutes the largest flux of CO2 from terrestrial ecosystems to the atmosphere. However, there still exist considerable uncertainties as to its actual magnitude, as well as its spatial and interannual ...
