    • Aridity and overgrazing have convergent effects on ecosystem structure and functioning in Patagonian rangelands 

      Gaitan, Juan Jose; Bran, Donaldo Eduardo; Oliva, Gabriel Esteban; Aguiar, Martín Roberto; Buono, Gustavo Gabriel; Ferrante, Daniela; Nakamatsu, Viviana Beatriz; Ciari, Georgina; Salomone, Jorge Manuel; Massara Paletto, Virginia; Garcia Martinez, Guillermo Carlos; Maestre, Fernando Tomás (2018-02)
      Over 65% of drylands are used for grazing of managed livestock. Understanding what drives grazing effects on the structure and functioning of rangelands is critical for achieving their sustainability. We studied a network ...
    • La competitividad del cluster ovino del noreste del Chubut 

      Salomone, Jorge Manuel (Facultad de Ciencias Económicas Sede Trelew, Universidad Nacional de la Patagonia San Juan Bosco, 2012)
      Las actividades productivas predominantes de la Provincia del Chubut están ligadas al uso y aprovechamiento de sus recursos naturales. Se destacan en este sentido la extracción y exportación de petróleo y gas, el aluminio, ...
    • Evaluating the performance of multiple remote sensing indices to predict the spatial variability of ecosystem structure and functioning in Patagonian steppes 

      Gaitan, Juan Jose; Bran, Donaldo Eduardo; Oliva, Gabriel Esteban; Ciari, Georgina; Nakamatsu, Viviana Beatriz; Salomone, Jorge Manuel; Ferrante, Daniela; Buono, Gustavo Gabriel; Massara Paletto, Virginia; Humano, Gervasio; Celdran, Diego Javier; Opazo, Walter Javier; Maestre, Fernando Tomás (2013-11)
      Assessing the spatial variability of ecosystem structure and functioning is an important step towards developing monitoring systems to detect changes in ecosystem attributes that could be linked to desertification processes ...
    • Manual para la instalación y lectura de monitores MARAS. Monitoreo Ambiental para Regiones Áridas y Semiáridas 

      Oliva, Gabriel Esteban; Gaitan, Juan Jose; Bran, Donaldo Eduardo; Nakamatsu, Viviana Beatriz; Salomone, Jorge Manuel; Buono, Gustavo Gabriel; Escobar, Juan Maria; Frank, Federico Carlos; Ferrante, Daniela; Humano, Gervasio; Ciari, Georgina; Suarez, Diego; Opazo, Walter Javier; Adema, Edgardo Osvaldo (EEA Santa Cruz, INTA, 2010)
      Los pastizales naturales de la Patagonia son ecosistemas únicos en su tipo y constituyen la base de la ganadería ovina tradicional. Los pastizales proveen de importantes servicios ambientales, ya que son ricos en diversidad ...

      Los pastizales naturales de la Patagonia son ecosistemas únicos en su tipo y constituyen la base de la ganadería ovina tradicional. Éstos proveen de importantes servicios ambientales, ya que son ricos en diversidad biológica, ...
    • Monitoring Patagonian Rangelands: The MARAS System 

      Oliva, Gabriel Esteban; Escobar, Juan Maria; Siffredi, Guillermo Lorenzo; Salomone, Jorge Manuel; Buono, Gustavo Gabriel (U.S. Department of Agriculture, Forest Service, 2006)
      Rangelands in Patagonia have been managed with a lack of regulation since the introduction of sheep in the late 1880’s. Most rangelands are under private freehold in ‘estancias’ and the rest are public and managed by small ...
    • Plant species richness and shrub cover attenuate drought effects on ecosystem functioning across Patagonian rangelands 

      Gaitan, Juan Jose; Bran, Donaldo Eduardo; Oliva, Gabriel Esteban; Maestre, Fernando Tomás; Aguiar, Martín Roberto; Jobbagy Gampel, Esteban Gabriel; Buono, Gustavo Gabriel; Ferrante, Daniela; Nakamatsu, Viviana Beatriz; Ciari, Georgina; Salomone, Jorge Manuel; Massara Paletto, Virginia (2014-10-22)
      Drought is an increasingly common phenomenon in drylands as a consequence of climate change. We used 311 sites across a broad range of environmental conditions in Patagonian rangelands to evaluate how drought severity and ...
    • Vegetation structure is as important as climate for explaining ecosystem function across Patagonian rangelands 

      Gaitan, Juan Jose; Oliva, Gabriel Esteban; Bran, Donaldo Eduardo; Maestre, Fernando Tomás; Aguiar, Martín Roberto; Jobbagy Gampel, Esteban Gabriel; Buono, Gustavo Gabriel; Ferrante, Daniela; Nakamatsu, Viviana Beatriz; Ciari, Georgina; Salomone, Jorge Manuel; Massara Paletto, Virginia (2014-11)
      1. Drylands cover about 41% of Earth’s land surface, and 65% of their area supports domestic livestock that depends on the above-ground net primary productivity (ANPP) of natural vegetation. Thus, understanding how biotic ...
