We present the analysis of medium-resolution spectra obtained at the Southern African Large Telescope ( SALT ) for nuclear globular clusters ( GCs ) in two dwarf spheroidal galaxies ( dSphs ) .
The galaxies have similar star formation histories , but they are situated in completely different environments .
ESO 269-66 is a close neighbour of the giant S0 NGC 5128 .
KKs 3 is one of the few truly isolated dSphs within 10 Mpc .
We estimate the helium abundance Y = 0.3 , age = 12.6 \pm 1 Gyr , \mbox { [ Fe / H ] } = -1.5 , -1.55 \pm 0.2 dex , and abundances of C , N , Mg , Ca , Ti , and Cr for the nuclei of ESO 269-66 and KKs 3 .
Our surface photometry results using HST images yield the half-light radius of the cluster in KKs 3 , r _ { h } = 4.8 \pm 0.2 pc .
We demonstrate the similarities of medium-resolution spectra , ages , chemical compositions , and structure for GCs in ESO 269-66 and KKs 3 and for several massive Galactic GCs with \mbox { [ Fe / H ] } \sim - 1.6 dex .
All Galactic GCs posses Extended Blue Horizontal Branches and multiple stellar populations .
Five of the selected Galactic objects are iron-complex GCs .
Our results indicate that the sample GCs observed now in different environments had similar conditions of their formation \sim 1 Gyr after the Big Bang .
