    • A case of allosuckling in wild guanacos (Lama guanicoe) 
      Zapata, Beatriz; Gaete, Gabriela; Correa, Loreto A.; González, Benito A.; Ebensperger, Luis A. (2009)
      Although allosuckling, the lactation of non-filial offspring, can be a costly behavior, it has been reported in several species across a wide range of mammalian orders. Monotocous species such as ungulates exhibit this ...
    • Allonursing in Captive Guanacos, Lama guanicoe: Milk Theft or Misdirected Parental Care? 
      Zapata, Beatriz; González, Benito A.; Ebensperger, Luis A. (2009)
      Females in several ungulates transfer milk to non-filial (NF) offspring, in a process known as allonursing. This behavior is less common in monotocous species, including most ungulates, and it has been associated ...
    • Avian ecosystem functions are influenced by small mammal ecosystem engineering 
      Root-Bernstein, Meredith; Fierro, Andres; Armesto, Juan J.; Ebensperger, Luis A. (2013)
      Background: Birds are important mobile link species that contribute to landscape-scale patterns by means of pollination, seed dispersal, and predation. Birds are often associated with habitats modified by small mammal ...
    • Effects of Habitat and Social Complexity on Brain Size, Brain Asymmetry and Dentate Gyrus Morphology in Two ... 
      Sobrero, Raúl; Fernández Aburto, Pedro; Ly-Prieto, Álvaro; Delgado, Scarlett E.; Mpodozis Marín, Jorge; Ebensperger, Luis A. (Karger, 2016)
      Navigational and social challenges due to habitat conditions and sociality are known to influence dentate gyrus (DG) morphology, yet the relative importance of these factors remains unclear. Thus, we studied three natural ...
    • Octodon degus kin and social structure 
      Garrett T., Davis; Vásquez Salfate, Rodrigo; Poulin, Elie; Oda, Esteban; Bazan León, Enrique; Ebensperger, Luis A.; Hayes, Loren D. (Oxford University Press, 2016-04)
      A growing body of evidence showing that individuals of some social species live in non-kin groups suggests kin selection is not required in all species for sociality to evolve. Here, we investigate 2 populations of Octodon ...
    • Toward an integrative understanding of social behavior: New models and new opportunities 
      Blumstein, Daniel T.; Ebensperger, Luis A.; Hayes, Loren D.; Vásquez Salfate, Rodrigo; Ahern, Todd H.; Burger, Joseph Robert; Dolezal, Adam G.; Dosmann, Andy; González-Mariscal, Gabriela; Harris, Breanna N.; Herrera, Emilio A.; Lacey, Eileen A.; Mateo, Jill; McGraw, Lisa A (2010)
      Social interactions among conspecifics are a fundamental and adaptively significant component of the biology of numerous species. Such interactions give rise to group living as well as many of the complex forms of cooperation ...
    • Validation of a radioimmunoassay for measuring fecal cortisol metabolites in the hystricomorph rodent, ... 
      Soto-Gamboa, Mauricio; Gonzalez, Sandra; Hayes, Loren D.; Ebensperger, Luis A. (2009)
      Determination of fecal steroid metabolites is a noninvasive technique that characterizes the physiological state of organisms without the physiological and psychological stress of handling. Although this technique has many ...
