Detection histories of grizzly bears in Grand Teton National Park, 2014-2015

This dataset contains detection histories of grizzly bears in areas of Grand Teton National Park that are open for elk harvest as part of the Elk Reduction Program. Sampling followed a robust design analysis with 6 primary sampling periods of 4 weekly secondary sampling periods each during 2014-2015. In both years, primary sampling periods were in July-August (no elk hunt), September-October (no elk hunt), and November-December (elk hunt). Detections were based on genetic sampling (hair samples from barbed-wire hair corrals, tree rubs or other structures, and elk carcasses). Detection histories were derived from a total of 274 grizzly bear hair samples of 31 individuals. Twenty-six unique individuals (4 F, 22 M) were retained for analysis.本数据集收录大提顿国家公园（Grand Teton National Park）内纳入麋鹿缩减计划（Elk Reduction Program）的开放狩猎区域内的灰熊检测历史数据。2014至2015年期间，采样采用稳健设计分析框架，共设置6个一级抽样周期，每个一级周期包含4个每周执行的二级抽样周期。两年的一级抽样周期均覆盖7-8月（无麋鹿狩猎活动）、9-10月（无麋鹿狩猎活动）以及11-12月（开展麋鹿狩猎活动）。本次检测基于基因采样开展，样本来源包括带刺铁丝网毛发收集栏、树木蹭痕或其他附着物上的毛发样本，以及麋鹿尸体样本。本检测历史数据总计源自31头灰熊的274份毛发样本，最终保留26头独立个体（雌性4头、雄性22头）用于后续分析。
