We have experimentally demonstrated that the c-axis magnetoresistance peak effect is determined by the subgap resistance of intrinsic Josephson junctions in Bi{sub 2}Sr{sub 2}CaCu{sub 2}O{sub 8+{delta}} (Bi2212). Given a Bi2212 single crystal, the effect may be predicted from the c-axis current-voltage (I-V) characteristics in {ital zero} magnetic field. At high magnetic field H, the I-V characteristics preserve their overall nonlinear shape at the transition temperature T{sub c}(H){le}T{sub c}(0) suggesting a smooth change of the vortex system with temperature. Observation of the gap feature below T{sub c}(0) at all {mu}{sub 0}H{le}7 T means that the upper critical field is not attained at these fields. {copyright} {ital 1997} {ital The American Physical Society}
