    • 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 ...
