BILLINGS, Mont. — The killing during hunting season of two collared wolves will affect a study examining wolf pack dynamics in and around Yellowstone National Park, a park biologist says. Doug Smith, the Yellowstone Wolf Project leader for the wolf reintroduction program, said the killing of the Cottonwood Pack's 7-year-old alpha female and her collared 2-year-old daughter means the pack's movements are no longer being tracked for the study by the park.
