    • 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 ...

    • Grazing and ecosystem service delivery in global drylands 

      Maestre, Fernando Tomas; Gaitan, Juan Jose; Aramayo, Maria Valeria Del Lujan; Ahumada, Rodrigo José; Ferrante, Daniela; Leder, Cintia V.; Oliva, Gabriel Esteban; Bran, Donaldo Eduardo; Gross, Nicolas (American Association for the Advancement of Science, 2022-11-25)
      Grazing represents the most extensive use of land worldwide. Yet its impacts on ecosystem services remain uncertain because pervasive interactions between grazing pressure, climate, soil properties, and biodiversity may ...

    • Perspectives on Rangeland Management Education and Research in Argentina 

      Anderson, David Lee; Bonvissuto, Griselda; Brizuela, Miguel Angel; Chiossone, Guillermo; Cibils, Andres Francisco; Cid, Maria Silvia; Feldman, Israel; Fernandez Grecco, Roberto; Kunst, Carlos Roberto; Oesterheld, Martin; Oliva, Gabriel Esteban; Paruelo, José María; Peinetti, Raúl; Villagra, Edgar Sebastian (Society for Range Management, 2011-02)
      Rangelands account for over two-thirds of Argentina’s land area and contribute uniquely to its biodiversity, agricultural livelihood, and cultural identity. Colossal mountain ranges and regional air mass movements create ...

    • 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 ...

    • Programa Nacional de Ecorregiones. La región Patagonia : Centros Regionales Patagonia Norte y Patagonia Sur 

      Mendez Casariego, Hugo; Bran, Donaldo Eduardo; Peralta, Carlos Ramiro; Madariaga, Marta Cecilia; Huerta, Guillermo Jose; Villarreal, Patricia; Oliva, Gabriel Esteban; Lopez Raggi, Facundo; Santagni, Adalberto; Easdale, Marcos Horacio; Sarmiento, Adolfo Carlos; Giraudo, Celso Gabriel; Rial, Pablo Eduardo; Escobar, Juan Maria; Marciani, Santiago Nicolas; Martinez, Roberto Simon; Elissalde, Nestor Osvaldo (EEA Bariloche, INTA, 2005)
      La Ecorregión Patagónica es una vasta región (780.000 km2), que cubre un amplio rango latitudinal (36º a 55º S), limitada al oeste (O) por la Cordillera de los Andes y al este (E) por el Océano Atlántico y se extiende desde ...

    • 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 ...
