    • 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 ...

    • Biotic and Abiotic Drivers of Topsoil Organic Carbon Concentration in Drylands Have Similar Effects at Regional and Global Scales 

      Gaitan, Juan Jose; Maestre, Fernando Tomás; Bran, Donaldo Eduardo; Buono, Gustavo Gabriel; Dougill, Andrew J.; Garcia Martinez, Guillermo Carlos; Ferrante, Daniela; Guuroh, Reginald Tang; Linstadter, Anja; Massara Paletto, Virginia; Thomas, Andrew David; Oliva, Gabriel Esteban (Springer, 2019-11)
      Drylands contain 25% of the world’s soil organic carbon (SOC), which is controlled by many factors, both abiotic and biotic. Thus, understanding how these factors control SOC concentration can help to design more sustainable ...

    • Coexistence of grasses and shrubs in Patagonian steppes. Norm or exception? 

      Biancari, Lucio; Oñatibia, Gastón Rafael; Gaitan, Juan Jose; Aguiar, Martín Roberto (Wiley, 2023-02-08)
      Community ecology’s central challenge is to define and corroborate theoretical frameworks that predict -at least in general terms- the composition of communities. The predictive power of a theory based on interspecific ...

    • Eruption, transport mechanisms and deposition of Paleogene ignimbrites, southwestern North Patagonian Massif, Argentina 

      Salani, Flavia; Contardo, Lucia Clarisa; Chernicoff, Carlos J. (Elsevier, 2023-11-01)
      The Paleocene-Eocene Catán Lil Ignimbrite (CLI) is one of the few occurrences within the explosive acid volcanism of this age in the extra-Andean region of the North Patagonian Massif. It represents a small-scale explosive ...

    • La variación temporal del índice NDVI predice los cambios temporales de la cobertura vegetal en las tierras secas de la Patagonia argentina 

      Gaitan, Juan Jose; Ciano, Nicolas Francisco; Oliva, Gabriel Esteban; Bran, Donaldo Eduardo; Butti, Lucas Ramiro; Cariac, German; Caruso, Cecilia Alejandra; Opazo, Walter Javier; Ferrante, Daniela; Echevarria, Daniela Carola; Buono, Gustavo Gabriel; Fantozzi, Anabella Giselle; Guirado, Emilio; Maestre, Fernando T. (Asociación Española de Ecología Terrestre (AEET), 2021-08-23)
      La variación temporal del índice NDVI predice los cambios temporales de la cobertura vegetal en las tierras secas de la Patagonia argentina. En las tierras secas, la vegetación natural es una fuente importante de sustento ...
