FRACASSI, Natalia G. et al. New species of mammals for the Lower Delta of the Paraná River and the adjacent flooding plain, Buenos Aires, Argentina. Mastozool. neotrop. [online]. 2010, vol.17, n.2, pp.367-373. ISSN 0327-9383.

We report the first records of presence of four mammal species (Dasypus novemcinctus, Cerdocyon thous, Procyon cancrivorus, and Axis axis) for the Lower Delta of the Paraná river and adjacent coastal lowlands, Buenos Aires province, Argentina. The absence of previous records of these species in the area, although it is a previously well surveyed area, suggests that their dissemination would be recent. The obtained number of records, their dispersion in the area, and comments from local people regarding the frequency of sightings would suggest that these species currently have established populations in the area.

Palavras-chave : Axis axis; Cerdocyon thous; Dasypus novemcinctus; Lower Delta of the Paraná River; Procyon cancrivorus.
