      MARAS (Monitoring of Arid and Semiarid Regions) consists of 379 ground monitors in Patagonia, a 624.500 km2 semiarid area of southern Argentina and Chile. The objective of this paper was to describe the system and analyze ...
    • 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 ...

      Gaitan, Juan Jose; Bran, Donaldo Eduardo; Oliva, Gabriel Esteban (Elsevier, 2019)
      The Argentinian Patagonia is a vast area (790,000-km2) of southern South America between 36° and 55°S. Almost 90% of the area is arid, semiarid or dry- subhumid (drylands) and covers important and heterogeneous ecological ...
    • 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 ...

    • Remotely‐sensed primary productivity shows that domestic and native herbivores combined are overgrazing Patagonia 

      Oliva, Gabriel Esteban; Paredes, Paula Natalia; Ferrante, Daniela; Cepeda, Carla Tamara; Rabinovich, Jorge Eduardo (Wiley; British Ecological Society, 2019-04)
      1.Carrying capacity is the maximum animal density an area can sustain without deterioration of its resources. Overgrazing has degraded Patagonia, but sheep stocks decreased and gave way to mixed systems with cattle, goats ...
    • The MARAS dataset, vegetation and soil characteristics of dryland rangelands across Patagonia 

      Oliva, Gabriel Esteban; Dos Santos, Eder; Osiris, Sofia; Umaña, Fernando; Massara Paletto, Virginia; Garcia Martinez, Guillermo Carlos; Caruso, Cecilia Alejandra; Cariac, German; Echevarria, Daniela Carola; Fantozzi, Anabella Giselle; Butti, Lucas Ramiro; Bran, Donaldo Eduardo; Gaitan, Juan Jose; Ferrante, Daniela; Paredes, Paula Natalia; Dominguez, Erwin; Maestre, Fernando Tomás (Nature Research, 2020)
      We present the MARAS (Environmental Monitoring of Arid and Semiarid Regions) dataset, which stores vegetation and soil data of 426 rangeland monitoring plots installed throughout Patagonia, a 624.500 km2 area of southern ...
    • The role of facultatively nectarivorous birds as pollinators of Anarthrophyllum desideratum in the Patagonian steppe: a geographical approach 

      Paiaro, Valeria; Cocucci, Andrea Aristides; Oliva, Gabriel Esteban; Sérsic, Alicia N. (2017-12)
      The endemic shrub Anarthrophyllum desideratum appears to be the only ornithophilous plant offering nectar as reward in the extensive Patagonian steppe. The identity of its floral visitor assemblage and to what extent this ...
    • La variación temporal del índice NDVI predice los cambios temporales de la cobertura vegetal en las tierras secas de la Patagonia argentina
