Abstract (from CDS):

The specific globular cluster frequencies (SN) for 24 dwarf elliptical (dE) galaxies in the Virgo and Fornax Clusters and the Leo Group that were imaged with the Hubble Space Telescope are presented. Combining all available data, we find that for nucleated dE (dE, N) galaxies, which are spatially distributed like giant elliptical galaxies in galaxy clusters, S{d1}NdE, N=6.5±1.2 and SN increases with MV, while for nonnucleated dE (dE, noN) galaxies, which are distributed like late-type galaxies, S{d1}NdE, noN=3.1±0.5 and there is little or no trend with MV. Thus, the SN values for dE galaxies are, on average, significantly higher than those for late-type galaxies, which have SN≲1. This suggests that dE galaxies are more akin to giant elliptical galaxies than to late-type galaxies. If there are dormant or stripped irregular galaxies hiding among the dE population, they are likely to be among the nonnucleated dE galaxies. Furthermore, the similarities in the properties of the globular clusters (GCs) and in the spatial distributions of dE, N galaxies and giant elliptical galaxies suggest that neither galaxy mass nor galaxy metallicity is responsible for the high values of SN. Instead, most metal-poor GCs may have formed in dwarf-sized fragments that merged into larger galaxies.
