Mean number of placental scars in wolves from throughout MN wolf range ( Table 5 ) did not maximize until females were 6-years old, except for one 10-year-old wolf, and the difference between the mean number of placental scars in 2-5-year-old wolves (5.95) and those ≥ 6 (6.86) was marginally significant ( P = 0.577; t = 1.92; d.f. = 90).
