  • The Amazon frontier of land-use change : croplands and consequences for greenhouse gas emissions 

    Galford, Gillian L.; Melillo, Jerry M.; Mustard, John F.; Cerri, Carlos E. P.; Cerri, Carlos C. (American Meteorological Society, 2010-10-28)
    The Brazilian Amazon is one of the most rapidly developing agricultural frontiers in the world. The authors assess changes in cropland area and the intensification of cropping in the Brazilian agricultural frontier state ...
  • Historical carbon emissions and uptake from the agricultural frontier of the Brazilian Amazon 

    Galford, Gillian L.; Melillo, Jerry M.; Kicklighter, David W.; Mustard, John F.; Cronin, Timothy W.; Cerri, Carlos E. P.; Cerri, Carlos C. (Ecological Society of America, 2011-04)
    Tropical ecosystems play a large and complex role in the global carbon cycle. Clearing of natural ecosystems for agriculture leads to large pulses of CO2 to the atmosphere from terrestrial biomass. Concurrently, the remaining ...
  • 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 ...
