Star clusters are fundamental building blocks of galaxies. Their formation is related to the density and pressure in progenitor molecular clouds and their environmental conditions. To understand better the dynamical processes driving star formation and chemical evolution, we compare ages, metallicities, and alpha-element abundance ratios of globular clusters in nearby dwarf galaxies of different luminosities and morphological types, and situated in different environments. The data are based on our 6m telescope medium-resolution spectroscopic observations. We find that a mean metallicity of GCs in a galaxy at a given age is higher for early-type dwarfs, than for late-type dwarf irregulars and spirals.
