    • Comparative basal metabolic rate among passerines and the food habit hypothesis 
      Sabat Kirkwood, Alejandro Pablo; Ramírez Otárola, Natalia; Barceló, Gonzalo; Salinas, Jonathan; Bozinovic, Francisco (ELSEVIER SCIENCE INC, 2010-05-15)
      The food habit hypothesis (FHH) predicts that mass-independent BMR is associated with dietary traits. In spite of decades of research, the FHH remains controversial, in part because ambiguities surrounding diet categorization ...
    • Temporal variation in isotopic composition of Pygoscelis penguins at Ardley Island, Antarctic: Are foraging ... 
      Negrete, Pablo; Sallaberry Ayerza, Michel; Barceló, Gonzalo; Maldonado, Karin; Perona, Franco; McGill, Rona A.R.; Quillfeldt, Petra; Sabat Kirkwood, Alejandro Pablo (Springer Verlag, 2017)
      © 2016, Springer-Verlag Berlin Heidelberg.Several studies have suggested that penguins are undergoing a major restructuring of their feeding habits and distribution after drastic climatic changes in the Antarctic Peninsula ...
    • Thermal history can affect the short-term thermal acclimation of basal metabolic rate in the passerine ... 
      Barceló, Gonzalo; Salinas, Jonathan; Cavieres, Grisel; Canals Lambarri, Mauricio; Sabat Kirkwood, Alejandro Pablo (2009)
      The obligatory cost of living for endotherms is measured by basal metabolic rate (BMR), a variable that is known to change after thermal acclimation. However, the relative timing between variation in ambient temperature ...
