We study the ultraviolet to far-infrared spectral energy distributions of a sample of intermediate-redshift (0.2 ≤ z ≤ 0.7) UV-selected galaxies from the ELAIS-N1 and ELAIS-N2 fields by fitting a multiwavelength dataset to a library of GRASIL templates. The dust attenuation of low mass galaxies increases as redshift decreases, and this trend seems to disappear for galaxies with M* ≥ 1011 M&sun;. This result is consistent with a mass-dependent evolution of the dust to gas ratio, which could be driven by a mass-dependent efficiency of star formation in star-forming galaxies. The specific star formation rates decrease with increasing stellar mass at all redshifts, and for a given stellar mass the specific star formation rate decreases with decreasing redshift.
