dc.descriptionAbstracts: Using a sample of 10 low x-ray luminosity galaxy clusters (Nilo Castellón et al. 2013B), we studied the properties of 146 galaxies classified as members in a redshift range of 0.185 < z < 0.701. Following Concelice et al. 2000, we define the galaxy concentration index (C) , as the ratio of two circular radii which contain 80 and 20 percent of the total Petrosian flux. Mainly, we observed an increment of C for early-type and lenticular galaxies at redshifts lower than 0.3, that can be related to the presence of giant galaxies in these low redshift clusters (C > 4). Contrary to these results, for late-type galaxies we found smaller C values for the lower redshift clusters. These results could be associated to the morphological evolution of galaxies, as proposed by different authors (Poggianti et al. 2009, Dressler et al. 2009) for rich clusters.en
