The sensitivity of moderate ${\mathit{p}}_{\mathit{T}}$\ensuremath{\lesssim}8 GeV/c singles inclusive spectra in nuclear collisions to gluon shadowing and jet quenching is estimated using the higing Monte Carlo model. We show how the systematic study of the nuclear dependence of those spectra in p+A can be used to determine the magnitude of gluon shadowing and how the enhanced suppression in A+A would provide information on the energy-loss mechanisms in dense partonic matter.
