We present a summary of measurements of single-bunch collective effects in the Advanced Light Source (ALS). These effects include bunch lengthening, energy spread increase, HOM loss measurements, head-tail damping rates, current-dependent tune shifts, and transverse mode coupling instability threshold. The longitudinal measurements are consistent with a broadband impedance {vert_bar}{ital Z}{sub {parallel}}/{ital n}{vert_bar}{sub eff}=0.22{plus_minus}0.07 {Omega} and transverse measurements indicate broadband impedances of {ital Z}{sub {ital y},eff}=155 k{Omega}/m and {ital Z}{sub {ital x},eff}=58 k{Omega}/m. {copyright} {ital 1996 American Institute of Physics.}
