    • 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 ...
    • Ecological drivers of group living in two populations of the communally rearing rodent, Octodon degus 
      Ebensperger, Luis A.; Sobrero, Raúl; Quirici, Verónica; Castro, Rodrigo A.; Ortiz Tolhuysen, Liliana; Vargas, Francisco; Burger, Joseph Robert; Quispe, René; Villavicencio, Camila P.; Vásquez Salfate, Rodrigo; Hayes, Loren D. (Springer, 2012)
      Intraspecific variation in sociality is thought to reflect a trade-off between current fitness benefits and costs that emerge from individuals' decision to join or leave groups. Since those benefits and costs may be ...
    • Microclimate and microhabitat selection in nocturnal rodents of central Chile: A test between biophysical ... 
      Ebensperger, Luis A.; Simonetti Zambelli, Javier Andrés (Walter de Gruyter GmbH, 1996)
      We contrasted two approaches to test the hypothesis that microclimate influences selection of microhabitat by two species (Abrothryx longipilis and Phyllotis darwini) of nocturnal rodents of central Chile. Microhabitats ...
    • Relatedness does not predict vigilance in a population of the social rodent Octodon degus 
      Quirici, Verónica; Palma, Macarena; Sobrero, Raúl; Faugeron, Sylvain; Ebensperger, Luis A. (Springer, 2013)
      The possibility that social foragers adjust and coordinate their scanning activity when in the presence of close relatives to attain inclusive fitness benefits remains controversial and scarcely examined. To this aim, ...
    • Vigilance and collective detection of predators in degus (Octodon degus) 
      Ebensperger, Luis A.; Hurtado, María José; Ramos Jiliberto, Rodrigo (BLACKWELL, 2006-09)
      Individuals of social and partially social species typically reduce their vigilance activity when foraging in groups. As a result, per capita risk of predation decreases and individuals allocate more time to foraging and ...
