In this work, we aim to study the evolutionary history of massive elliptical galaxies in low density environments, through the characterization of their globular cluster systems (GCS). In particular, we focus on bright elliptical galaxies, typical of cluster environments rather than of the groups they inhabit, which might show signs of interaction with their neighbors. The two photometric studies correspond to the GCSs of NGC 6876 and NGC 3613, both of them observed with the GMOS camera in Gemini South. These two galaxies inhabit different poor groups and fall under the previous description.
