    • Contrasting Genetic Structure and Diversity of Galaxias maculatus (Jenyns, 1848) Along the Chilean Coast: Stock Identification for Fishery Management 

      González Wevar, Claudio; Salinas, Pilar; Hüne, Mathias; Segovia, Nicolás; Vargas Chacoff, Luis; Oda, Esteban; Poulin, Elie (Oxford Univ Press, 2015)
      Galaxias maculatus (Pisces: Galaxiidae) commonly known as "puye" has a disjunct distribution along the Southern Hemisphere including landlocked and migratory populations at latitudes over 30 degrees S in South America, ...
    • Field assessment of Trypanosoma cruzi infection and host survival in the native rodent Octodon degus 

      Botto Mahan, Carezza; Bacigalupo, Antonella; Correa, Juana P.; Oda, Esteban; Solari Illescas, Aldo (2012)
      Chagas disease is a zoonosis caused by the flagellated parasite Trypanosoma cruzi and transmitted by triatomine insects to several mammalian species acting as reservoir hosts. In the present study, we assess T. cruzi-prevalence, ...
    • 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 ...
    • Parasitic infection alters rodent movement in a semiarid ecosystem 

      Jiménez, Carolina; Fontúrbel, Francisco E.; Oda, Esteban; Ramírez, Patricia A.; Botto Mahan, Carezza (Elsevier, 2015)
      Parasite-mediated behavioral changes in their hosts have been documented in many species, but field evidence is scarce. The protozoan Trypanosoma cruzi is transmitted by insect vectors to several mammal species. Although ...
    • Spatial distribution of an infectious disease in a small mammal community 

      Correa, Juana P.; Bacigalupo, Antonella; Fontúrbel, Francisco E.; Oda, Esteban; Cattan Ayala, Pedro; Solari Illescas, Aldo; Botto Mahan, Carezza (Springer, 2015)
      Chagas disease is a zoonosis caused by the parasite Trypanosoma cruzi and transmitted by insect vectors to several mammals, but little is known about its spatial epidemiology. We assessed the spatial distribution of T. ...
    • Temporal fluctuation in shrub species preferences of two native rodents: The effect of infection status on habitat use 

      Donoso, M. Isabel; Fonturbel, Francisco E.; Cares, Rocio A.; Oda, Esteban; Ramírez, Patricia A.; Botto Mahan, Carezza (Wiley-Blackwell, 2016)
      Small mammals use plant species for gathering food resources and for shelter. Preferences for certain plant species are related to nutritional restrictions and behavioural patterns, which could be altered in the presence ...
