      Novoa, F. Fernando; Rivera Hutinel, Antonio; Rosenmann, Mario; Sabat Kirkwood, Alejandro Pablo (Sociedad de Biologia de Chile, 2005)
      Studies of metabolic capacities in rodents have been largely studied at an inter-specific levels, but physiological capacities of populations belonging to the same species have received lesser attention. Here we studied ...
    • Lizards and rabbits may increase Chagas infection risk in the Mediterranean-type ecosystem of South America 
      San Juan, Esteban; Araya Donoso, Raúl; Sandoval Rodríguez, Alejandra; Yáñez Meza, Andrea; Quiroga, Nicol; Botto Mahan, Carezza (Nature, 2020)
      Studies of host-parasite relationships largely benefit from adopting a multifactorial approach, including the complexity of multi-host systems and habitat features in their analyses. Some host species concentrate most ...
