Abstract

AUSTRICH, Ailin; STEINMANN, Andrea R; BONATTO, Florencia  and  GOMEZ, Daniela. Efecto de adultos en el establecimiento de juveniles de Calomys musculinus (Rodentia: Sigmodontinae). Mastozool. neotrop. [online]. 2014, vol.21, n.1, pp.101-107. ISSN 0327-9383.

Under the hypothesis that in enclosure populations reproductively active individuals of Calomys musculinus exclude juveniles of the same sex, we test the predictions that: 1) home range overlap degree is lower between adults and juveniles of the same sex; 2) juveniles do not establish within the home range of adults of their same sex. Our results partially support the hypothesis; although reproductively active adults affected the establishment of juveniles, this effect was clearly sex-specific as regards the spatial location of juvenile in relation to adult male home ranges.
