Abstract:  We estimate the abundances of carbon, nitrogen, magnesium,
calcium, and iron for 176 globular clusters (GCs) in M31.  The analysis is
based on high S/N, intermediate resolution, integrated GC spectra obtained
with MMT/Hectospec and state-of-the-art single stellar population models.
The results are discussed in light of current chemical evolution models.  A
follow-up program using adaptive optics-assisted NIR spectroscopy with
Gemini is briefly described.
