Changes in rodent communities according to the landscape structure in an urban ecosystem
We analyzed the relation between rodent communities composition and diversity and the landscape structure in the city of Buenos Aires. Between October 2002 and December 2005 rodent samplings were conducted in a natural reserve, three parklands, three shantytowns and two industrial-residential neighb...

We analyzed the relation between rodent communities composition and diversity and the landscape structure in the city of Buenos Aires.

Landscape structure at each site was characterized by the proportion of the surface occupied by different land-cover types, and the proportion covered by buildings. We caught 413 rodents of the following species: the native Oligoryzomys flavescens, Deltamys kempi, Calomys musculinus and Cavia aperea; and the introduced Rattus norvegicus, R. rattus and Mus musculus.
