The aim of this research was to compare the abundance, growth, age structure and reproductive patterns of Rattus norvegicus and Mus musculus populations of a shanty town and a parkland in the city of Buenos Aires, Argentina. Live trapping of rodents was conducted in each area every 2 months, from September 2006 to August 2007. Abundance of R. norvegicus and M. musculus was significantly higher in the shanty town than in the parkland. Abundance of both species showed significant differences between trapping sessions in both study sites. Both species showed a peak in abundance in summer in the parkland and also in autumn in the shanty town. Age structure of both species differed between summer-autumn and winter-spring in the shanty town. In the parkland, pregnant females of both species were only found in spring-summer. No significant differences were found in any of the reproductive parameters compared between the shanty town and the parkland. Our results suggest that the shanty town represents a favourable but not constant habitat for rodents throughout the year.
