MCINTYRE, Nancy E. et al. Ecological correlates of serological status for Bayou virus in Oryzomys palustris (Rodentia: Sigmodontinae). Mastozool. neotrop. [online]. 2009, vol.16, n.1, pp.83-94. ISSN 0327-9383.

Home range size and habitat use of seropositive Oryzomys palustris, primary host for the Bayou strain of hantavirus, were compared to that of seronegative individuals from March 2002 - August 2003 in a longitudinal field population study. There were significant macrohabitat associations with serological status, but selection for most microhabitat variables did not differ between seropositive and seronegative animals. Seropositive adult males moved farther (had larger home ranges) than did seronegatives and were larger in terms of mass and testes size. These patterns may reflect the influence of infection on rodent ecology in terms of dominance and access to preferred habitats.
