Using a sample of galaxies in groups (with halo masses less than $ \\simeq 10^{14} \\, \\mathrm{M_{\\odot}}$) from the Galaxy And Mass Assembly Survey, we find signatures of environmental quenching in high-mass groups ($M_{G} > 10^{12.5} \\, \\mathrm{M_{\\odot}}$). The mean integrated specific star formation rate of star-forming galaxies in high-mass groups is lower than for galaxies in low-mass groups or that are ungrouped, with $\\Delta \\log(sSFR/\\mathrm{yr^{-1}}","authors_text":"A.
