    • Direct and indirect effects of climate and vegetation on sheep production across Patagonian rangelands (Argentina) 

      Castillo, Daniel Alejandro; Gaitan, Juan Jose; Villagra, Edgar Sebastian (Elsevier, 2021-05)
      Extensive sheep production is an important agricultural industry in the Patagonia region of Argentina, where the most important production metric is the effective lambing rate of the sheep (L%). Climate factors can affect ...

    • Efecto de la severidad de quemado sobre la regeneración de la vegetación en el Monte Austral 

      Bran, Donaldo Eduardo; Cecchi, Gustavo; Gaitan, Juan Jose; Ayesa, Javier Alejandro; Lopez, Carlos Rodolfo (Asociación Argentina de Ecología, 2007-06)
      El fuego es un fenómeno recurrente en los ecosistemas del norte de la Patagonia y ocurren, fundamentalmente, luego de una serie de años húmedos que promueve el crecimiento de pastos. La acumulación de material combustible ...

    • 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 ...

    • Una herramienta para monitorear sequías en regiones áridas y semiáridas de Patagonia Norte 

      Easdale, Marcos Horacio; Lopez, Dardo Ruben; Bianchi, Emilio; Bruzzone, Octavio Augusto; Villagra, Edgar Sebastian; Siffredi, Guillermo Lorenzo; Gaitan, Juan Jose; Umaña, Fernando; Oricchio, Patricio (Gerencia de Comunicación e Imagen Institucional, DNA SICC, INTA, 2012-08)
      La variabilidad ambiental es una característica de regiones pastoriles áridas y semiáridas, siendo la sequía uno de los principales problemas en sistemas ganaderos extensivos, con implicancias productivas y económicas tanto ...

    • 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 ...

    • Soil fungal abundance and plant functional traits drive fertile island formation in global drylands 

      Ochoa-Hueso, Raúl; Eldridge, David J.; Delgado-Baquerizo, Manuel; Soliveres, Santiago; Bowker, Matthew A.; Gross, Nicolás; Le Bagousse-Pinguet, Yoann; Quero, José L.; García-Gómez, Miguel; Valencia, Enrique; Arredondo, Tulio; Beinticinco, Laura; Bran, Donaldo Eduardo; Cea, Alex; Coaguila, Daniel; Dougill, Andrew J.; Espinosa, Carlos I.; Gaitan, Juan Jose; Guuroh, Reginald T.; Guzmán, Elizabeth; Gutiérrez, Julio R.; Hernández, Rosa M.; Huber-Sannwald, Elisabeth; Jeffries, Thomas; Linstädter, Anja; Mau, Rebecca L.; Monerris, Jorge; Prina, Anibal; Pucheta, Eduardo; Stavi, Ilan; Thomas, Andrew; Zaady, Eli; Singh, Brajesh K.; Maestre, Fernando Tomás (2018)
      Dryland vegetation is characterized by discrete plant patches that accumulate and capture soil resources under their canopies. These “fertile islands” are major drivers of dryland ecosystem structure and functioning, yet ...

    • Surface indicators are correlated with soil multifunctionality in global drylands 

      Eldridge, David John; Delgado-Baquerizo, Manuel; Quero, José Luis; Ochoa, Victoria; Gozalo, Beatriz; García-Palacios, Pablo; Escolar, Cristina; García-Gómez, Miguel; Prina, Anibal; Bowker, Mathew Alan; Bran, Donaldo Eduardo; Castro, Ignacio; Cea, Alex; Derak, Mchich; Espinosa, Carlos Ivan; Florentino, Adriana; Gaitan, Juan Jose; Gatica, Gabriel; Gómez-González, Susana; Ghiloufi, Wahida; Gutierrez, Julio Roberto; Gusmán-Montalván, Elizabeth; Hernández, Rosa Mary; Hughes, Frederic Mendes; Muiño, Walter; Monerris, Jorge; Ospina, Abelardo; Ramirez, David A.; Ribas-Fernández, Yanina Antonia; Lisboa Romão, Roberto; Torres-Díaz, Cristian; Koen, Terrance B.; Maestre Gil, Fernando Tomás (Wiley, 2020-02)
      1. Multiple ecosystem functions need to be considered simultaneously to manage and protect the several ecosystem services that are essential to people and their environments. Despite this, cost effective, tangible, relatively ...

    • 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 ...
