自然资源和野生动物管理者必须平衡不同利益相关者的不同优先事项。为了管理这些优先事项，需要对公众突出的主题有坚定的理解。媒体经常报道对公众重要的问题;因此，这些报道可能是衡量公众利益的一个有用尺度。然而，有效的方法来区分媒体报道的野生动物管理问题的相关的不同主题和这些主题的显着性的变化一直缺乏。我们使用潜在的狄利克雷分配，贝叶斯混合模型，定量评估周围的灰狼（狼），这是重新引入到爱达荷州（美国）的主题的显着性。1995年我们分析了1960年至2015年发表在爱达荷州报纸上的文章。我们确定了6个与灰狼相关的不同主题：政策，狩猎，生物状态，管理实施，恢复和人狼冲突。在引入狼之前和之后（1995年）以及从美国濒危物种法案（2009年）中删除狼之前和之后，主题的突出性显着不同，强调这些事件是如何公开讨论和构建问题的转折点。当地记者撰写的文章更有可能报道有关人与狼之间冲突的主题，而来自国家媒体的文章则更多地报道有关狼政策和生物状况的主题。在管理一个有争议的、分布广泛的、长寿的野生动物物种的背景下，我们的方法可以帮助指导一套管理策略的位置和时间（例如，媒体关系计划和利益相关者参与），促进人类与野生动物在不同景观中的共存。
Natural resource and wildlife managers must balance the disparate priorities of a diversity of stakeholders. To manage these priorities, a firm understanding of topics salient to the public is needed. The media often report on issues of importance to the public; therefore, these reports may be a useful measure of public interest. However, efficient methods for distinguishing diverse topics related to a wildlife management issue reported in the media and changes in the salience of those topics have been lacking. We used latent Dirichlet allocation, a Bayesian mixture model, to quantitatively assess the salience of topics surrounding the gray wolf (Canis lupus), which was reintroduced to Idaho (U.S.A.) in 1995. We analyzed articles published from 1960 to 2015 in an Idaho newspaper. We identified 6 distinct topics associated with gray wolves: policy, hunting, biological status, implementation of management, recovery, and human-wolf conflict. The salience of topics pre- and postreintroduction of wolves (1995) and pre- and postdelisting of wolves from the U.S. Endangered Species Act (2009) differed significantly, underscoring that these events were turning points in how issues were being publicly discussed and framed. Articles written by the local reporters were more likely to report on topics regarding conflict between humans and wolves, whereas articles sourced from a national outlet reported more on topics pertaining to wolf policy and biological status. In the context of managing a contentious, far-ranging, and long-lived wildlife species, our methods can help guide the location and timing of a suite of management strategies (e.g., media relation plans and stakeholder engagement) that promote human-wildlife coexistence across different landscapes.
