      In ecosystems, soil microbial variables characterization are used to determine soil biological health and the response of soils to environmental stress. Although there are strong associations between plants and soil ...

    • Extreme drought impacts have been underestimated in grasslands and shrublands globally 

      Smith, Melinda D.; Wilkins, Kate D.; Holdrege, Martin C.; Wilfahrt, Peter A.; Collins, Scott L.; Knapp, Alan K.; Sala, Osvaldo E.; Dukes, Jeffrey S.; Phillips, Richard P.; Yahdjian, Laura; Peri, Pablo Luis; Zuo, Xiaoan (National Academy of Sciences (Estados Unidos), 2024-01-08)
      Climate change is increasing the frequency and severity of short-term (~1 y) drought events—the most common duration of drought—globally. Yet the impact of this intensification of drought on ecosystem functioning remains ...

    • Forage provision is more affected by droughts in arid and semi-arid than in mesic rangelands

      Droughts are projected to increase in magnitude, frequency and duration in the near future. In rangelands, the provision of valuable ecosystem services such as forage supply for livestock productivity is intimately linked ...

    • Higher than expected N2O emissions from soybean crops in the Pampas Region of Argentina: Estimates from DayCent simulations and field measurements 

      Della Chiesa, Tomas; Piñeiro, Gervasio; Del Grosso, Stephen J.; Parton, William J.; Araujo, Patricia Ines; Yahdjian, Laura (Elsevier, 2022-08)
      In developing countries, agriculture generally represents a large fraction of GHG emissions reported in National Inventories, and emissions are typically estimated using Tier 1 IPCC guidelines. However, field data and ...
