    • Phylogeography of Oligoryzomys longicaudatus (Rodentia : Sigmodontinae) in temperate South America 
      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) from ...
    • Phylogeography of Oligoryzomys longicaudatus (Rodentia : Sigmodontinae) in temperate South America 
      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) ...
    • Predicting effects of ecosystem engineering on species richness along primary productivity gradients 
      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 ...
    • Priority areas for the conservation of coastal marine vertebrates in Chile 
      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 ...
    • Rain forest islands in the chilean semiarid region: Fog-dependency, ecosystem persistence and tree regeneration 
      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 ...
    • Rarity in Chilean forest birds: which ecological and life-history traits matter? 
      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 ...
    • 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 ...
    • Scaling metabolic rate fluctuations 
      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 ...
    • Selective extinction of late Neogene bivalves on the temperate Pacific coast of South America 
      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 ...
    • 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. ...
