We present detailed chemical abundances of Fe, Ca and Ba for 17 globularclusters (GCs) in 5 Local Group dwarf galaxies: NGC 205, NGC 6822, WLM, the SMCand LMC. These abundances are part of a larger sample of over 20 individualelements measured in GCs in these galaxies using a new analysis method for highresolution, integrated light spectra. Our analysis also provides age andstellar population constraints. The existence of GCs in dwarf galaxies with arange of ages implies that there were episodes of rapid star formationthroughout the history of these galaxies; the abundance ratios of theseclusters suggest that the duration of these burst varied considerably fromgalaxy to galaxy. We find evolution of Fe, Ca, and Ba with age in the LMC, SMC,and NGC 6822 that is consistent with extended, lower-efficiency SF betweenbursts, with an increasing contribution of low-metallicity AGB ejecta at latetimes. Our sample of GCs in NGC 205 and WLM are predominantly old andmetal-poor with high [Ca/Fe] ratios, implying that the early history of thesegalaxies was marked by consistently high SF rates.
