On 3 October, a few weeks after Montana opened its first legal wolf-hunting season in decades, a hunter killed the alpha female of Yellowstone Park's Cottonwood Pack, whose behavior, travels, life history, and genealogy had been studied in detail by scientists for years. Her death, and that of five other pack members also shot outside Yellowstone, has irrevocably changed what had been a unique long-term study, the researchers say.
