    • Bofedales: high altitude peatlands of the central Andes 
      Squeo, Francisco A.; Warner, Barry; Aravena, Ramón; Espinoza, Diana (SOCIEDAD BIOLOGIA CHILE, 2006-06)
      There is an exceptional group of alpine peatlands in the world situated in the and grasslands of the central Andes. The peatlands in northern Chile occur in the most arid part of their range. Members of the Juncaceae are ...
    • Bottom-up control of consumers leads to top-down indirect facilitation of invasive annual herbs in semiarid Chile 
      Madrigal, Jaime; Kelt, Douglas A.; Meserve, Peter L.; Gutiérrez, Julio R.; Squeo, Francisco A. (ECOLOGICAL SOC AMER, 2011-02)
      The abundance of exotic plants is thought to be limited by competition with resident species (including plants and generalist herbivores). In contrast, observations in semiarid Chile suggest that a native generalist rodent, ...
    • Extreme climatic events shape arid and semiarid ecosystems 
      Holmgren, Milena; Stapp, Paul; Dickman, Chris R.; Gracia, Carlos; Graham, Sonia; Gutiérrez, Julio R.; Hice, Christine; Jaksic, Fabián; Kelt, Douglas A.; Letnic, Mike; Lima, Mauricio; López, Bernat C.; Meserve, Peter L.; Milstead, W. Bryan; Polis, Gary A.; Previtali, M. Andrea; Richter, Michael; Sabaté, Santi; Squeo, Francisco A. (ECOLOGICAL SOC AMER, 2006-03)
      Climatic changes associated with the El Nino Southern Oscillation (ENSO) can have a dramatic impact on terrestrial ecosystems worldwide, but especially on arid and semiarid systems, where productivity is strongly limited ...
    • Herbivory and plant growth rate determine the success of El Nino Southern Oscillation-driven tree establishment ... 
      Holmgren, Milena; López, Bernat C.; Gutiérrez, Julio R.; Squeo, Francisco A. (BLACKWELL, 2006-12)
      While climatic extremes are predicted to increase with global warming, we know little about the effect of climatic variability on biome distribution. Here, we show that rainy El Nino Southern Oscillation (ENSO) events can ...
    • Reduced herbivore pressure under rainy ENSO conditions could facilitate dryland reforestation 
      Gutiérrez, Julio R.; Holmgren, Milena; Manrique, Rosa; Squeo, Francisco A. (ACADEMIC PRESS LTD ELSEVIER SCIENCE LTD, 2007-01)
      Most semi-arid and and regions around the world have lost a major part of their original vegetation.. Restoration of once shrublands and woodlands is often challenged by low seedling establishment success due to water ...
    • Reduced herbivory during simulated ENSO rainy events increases native herbaceous plants in semiarid Chile 
      Manrique, Rosa; Gutiérrez, Julio R.; Holmgren, Milena; Squeo, Francisco A. (SPRINGER, 2007-07)
      El Nino Southern Oscillation (ENSO) events have profound consequences for the dynamics of terrestrial ecosystems. Since increased climate variability is expected to favour the invasive success of exotic species, we conducted ...
    • A synthesis of ENSO effects on drylands in Australia, North America and South America 
      Holmgren, Milena; Stapp, Paul; Dickman, Chris R.; Gracia, Carlos; Graham, Sonia; Gutiérrez, Julio R.; Hice, C.; Jaksic, Fabián; Kelt, Douglas A.; Letnic, Mike; Lima, Mauricio; López, Bernat C.; Meserve, Peter L.; Milstead, W. Bryan; Polis, Gary A.; Previtali, M. Andrea; Richter, Michael; Sabaté, Santi; Squeo, Francisco A. (2006)
    • Tree establishment along an ENSO experimental gradient in the Atacama desert 
      Squeo, Francisco A.; Holmgren, Milena; Jiménez, Milagros; Alban, Luis; Reyes, José; Gutiérrez, Julio R. (OPULUS PRESS UPPSALA AB, 2007-04)
      Questions: (1) What are the roles of regional climate and plant growth rate for seedling establishment during ENSO rainy pulses along the western coast of South America? (2) What is the water threshold for tree seedling ...
