    • Palma, R. Eduardo; Rivera Milla, Eric; Salazar Bravo, Jorge; Torres Pérez, Fernando; Pardiñas, Ulyses F. J.; Marquet, Pablo A.; Spotorno Oyarzún, Ángel; Meynard, Andrés P.; Yates, Terry L. (ALLIANCE COMMUNICATIONS GROUP DIVISION ALLEN PRESS, 2005-02)
      Phylogeographic relationships were evaluated at the intraspecific level using nucleotide sequence data from the mitochondrial cytochrome b gene of representative specimens of ‘‘colilargo’’ (Oligoryzomys longicaudatus) ...

      Phylogeographic relationships were evaluated at the intraspecific level using nucleotide sequence data from the mitochondrial cytochrome b gene of representative specimens of "colilargo" (Oligoryzomys longicaudatus) from ...
    • Badano, Ernesto I.; Marquet, Pablo A.; Cavieres, Lohengrin Alexis (ELSEVIER, 2010)
      Physical ecosystem engineering is the process by which some species change the distribution of materials and energy in ecosystems. Although several studies have shown that this process is a driver of local species ...
    • Tognelli, Marcelo F.; Silva García, Celeste; Labra, Fabio A.; Marquet, Pablo A. (ELSEVIER, 2005-12)
      In the past decade, there has been growing concern about the rapid degradation of marine ecosystems due to anthropogenic causes. Consequently, identifying priority areas for the conservation of marine biodiversity has ...
    • del-Val, Ek; Armesto, Juan J.; Barbosa, Olga; Christie, Duncan A.; Gutiérrez, Alvaro G.; Jones, Clive G.; Marquet, Pablo A.; Weathers, Kathleen C. (SPRINGER, 2006-06)
      Tree presence in semiarid ecosystems is generally constrained by insufficient annual rainfall. However, in semiarid Chile, rainforest patches dominated by Aextoxicon punctatum are unexpectedly found on coastal mountaintops ...
    • Cofré, Hernán L.; Bohning Gaese, Katrin; Marquet, Pablo A. (BLACKWELL, 2007-03)
      While it is a truism that species rarity is non-randomly distributed across regions, habitats, and taxa, there is little consensus on which factors are the best predictors of low abundances and restricted geographical ...
    • 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 ...
    • Labra, Fabio A.; Marquet, Pablo A.; Bozinovic, Francisco (NATL ACAD SCIENCES, 2007-06-26)
      Complex ecological and economic systems show fluctuations in macroscopic quantities such as exchange rates, size of companies or populations that follow non-Gaussian tent-shaped probability distributions of growth rates ...
    • Rivadeneira, Marcelo; Marquet, Pablo A. (PALEONTOLOGICAL SOC INC, 2007)
      We assessed selective extinction patterns in bivalves during a late Neogene mass extinction event observed along the temperate Pacific coast of South America. The analysis of 99 late Neogene and Quaternary fossil sites ...
    • 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. ...
