    • 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 ...

    • El clima modula los efectos del pastoreo sobre la productividad primaria en ecosistemas áridos de Argentina 

      Calvo, Dianela Alejandra; Peter, Guadalupe; Gaitan, Juan Jose (Asociación Española de Ecología Terrestre, 2021-09-13)
      La introducción de fuentes de agua artificiales para uso ganadero en ecosistemas donde el agua ha estado ausente durante su evolución ha provocado cambios en la vegetación. Se ha demostrado que existe una atenuación radial ...

    • Climate mediates the biodiversity–ecosystem stability relationship globally 

      García Palacios, Pablo; Gross, Nicolás; Gaitan, Juan Jose; Maestre, Fernando Tomás (2018-08)
      The insurance hypothesis, stating that biodiversity can increase ecosystem stability, has received wide research and political attention. Recent experiments suggest that climate change can impact how plant diversity ...

    • 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 ...

    • 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 ...
