    • Between-population differences in digestive flexibility in the olivaceous field mouse 
      Bozinovic, Francisco; Rojas, José M.; Maldonado, Karin; Sabat Kirkwood, Alejandro Pablo; Naya, Daniel (ELSEVIER GMBH, 2010-08-28)
      The flexibility of digestive traits characterizes a standard model of physiological flexibility, demonstrating that animals adjust their digestive attributes in order to maximize overall energy return. Using an intraspecific ...
    • Digestive and metabolic flexibility allows female degus to cope with lactation costs 
      Naya, Daniel; Ebensperger, Luis A.; Sabat Kirkwood, Alejandro Pablo; Bozinovic, Francisco (UNIV CHICAGO PRESS, 2008-11-01)
      Lactation is the most energetically demanding period in the life cycle of female mammals, and its effects on digestive flexibility and the size of internal organs have been extensively studied in laboratory mice and ...
    • Digestive morphology and enzyme activity in the Andean toad, Bufo spinulosus: hard-wired or flexible physiology? 
      Naya, Daniel; Farfán, Gonzalo; Sabat Kirkwood, Alejandro Pablo; Méndez, Marco; Bozinovic, Francisco (ELSEVIER SCIENCE INC, 2005-02)
      Gut plasticity is a trait with implications on animal performance. However, and despite their importance as study models in physiology, research on gut flexibility in amphibians is scarce. In the present work, we analyse ...
    • Gut size variation among Bufo spinulosus populations along an altitudinal (and dietary) gradient 
      Naya, Daniel; Veloso Iriarte, Claudio; Bozinovic, Francisco (Finnish Zoological and Botanical Publishing Board, 2009)
      To date, digestive flexibility has been studied in dozens of vertebrate species. However, practically all of these works has ignored the importance of intraspecific physiological variability across populations inhabiting ...
    • Physiological flexibility and climate change: The case of digestive function regulation in lizards 
      Naya, Daniel; Veloso Iriarte, Claudio; Sabat Kirkwood, Alejandro Pablo; Bozinovic, Francisco (Elsevier, 2011)
      Our planet is undergoing fast environmental changes,which are referred as global change. In this newscenario, it is of paramount relevance to understand the mechanistic basis of animal responses to environmental change. Here ...
    • Seasonal Flexibility in Organ Size in the Andean Lizard Liolaemus moradoensis 
      Naya, Daniel; Veloso Iriarte, Claudio; Sabat Kirkwood, Alejandro Pablo; Bozinovic, Francisco (WILEY-LISS, DIV JOHN WILEY & SONS INC, 2010-10-21)
      The understanding of animal functioning in fluctuating environments is a major goal of physiological and evolutionary ecology. In temperate terrestrial habitats, one of the most pervasive changes in environmental conditions ...
