    • On the relationship between productivity and food chain length at different ecological levels 
      Arim, Matías; Marquet, Pablo A.; Jaksic, Fabián (UNIV CHICAGO PRESS, 2007-01)
      The effects of energy on food web structure have been debated for at least 80 years. Nevertheless, the empirical evidence is meager, especially from terrestrial ecosystems. We analyzed long-term temporal variation in food ...
    • On the relationship between trophic position, body mass and temperature: reformulating the energy limitation ... 
      Arim, Matías; Bozinovic, Francisco; Marquet, Pablo A. (BLACKWELL, 2007-09)
      Understanding the factors that constrain and drive changes in food chain length represents an open challenge in ecology. Although several explanatory hypotheses have been proposed, no synthesis has yet been achieved. The ...
    • Scaling and power-laws in ecological systems 
      Marquet, Pablo A.; Quiñones, Renato A.; Abades, Sebastián R.; Labra, Fabio A.; Tognelli, Marcelo F.; Arim, Matías; Rivadeneira, Marcelo (COMPANY OF BIOLOGISTS LTD, 2005-05)
      Scaling relationships (where body size features as the independent variable) and power-law distributions are commonly reported in ecological systems. In this review we analyze scaling relationships related to energy ...
    • Spread dynamics of invasive species 
      Arim, Matías; Abades, Sebastián R.; Neill, Paula E.; Lima, Mauricio; Marquet, Pablo A. (NATL ACAD SCIENCES, 2006-01-10)
      Species invasions are a principal component of global change, causing large losses in biodiversity as well as economic damage. Invasion theory attempts to understand and predict invasion success and patterns of spread. ...
