In the current paradigm globular clusters (GCs) were formed during major starburst episodes, due to galaxy mergers and interactions, or accreted from satellite galaxies. This implies a directconnection between the GC system and the evolutionary history of the host galaxy, and particularly its mass accretion history.We analysed the GCs radial distribution for a sample of intermediate luminosity early-type galaxies located in different environments, and supplemented it with literature results. In comparison with previous studies, our compilation expands the sample to fainter luminosities. A change in the scaling relations between the properties of the GC systems and those of the host galaxies might exist at M*~5×10^10 solar masses. We statistically compared our sample with the properties of the halos from a dark matter only simulation. The results point that the extension and effective radii of the GC systems scales with the virial radii and the projected effective radii of the halos.
