Abstract
We analyse evolutionary parameters of globular clusters in dwarf galaxies obtained in our medium-resolution spectroscopic observations, and their connection with the properties of the host galaxies. We find that 1) the metallicity spread in globular cluster systems is wider for larger galaxies; 2) metal-rich clusters are young and preferentially found in galaxies more massive than ∼10 9 M ⊙ ; 3) intermediate-age globular clusters in early-type dwarf galaxies are richer in metals than star clusters representing dynamically cold gas-rich environments in dwarf irregulars; 4) the age-metallicity relation is special for each galaxy, and depends not only on its mass, but also on some other factors, probably environmental conditions.
