Abstract

We summarize our results on the photometric metallicities and on the presence of metallicity gradients for nine M 81 group dSphs. The majority of our studied dSphs contains a significant fraction of intermediate–age stellar populations, which we consider as a function of the deprojected distance from the dominant galaxy of the group.
