Although widespread declines in insect biomass and diversity are increasing concerns within the scientific community, it remains unclear whether attention to pollinator declines has also increased within information sources serving the general public. Examining patterns of journalistic attention to the pollinator population crisis can also inform efforts to raise awareness about the importance of declines of insect species providing ecosystem services beyond pollination. We used the Global News Index developed by the Cline Center for Advanced Social Research at the University of Illinois at Urbana-Champaign to track news attention to pollinator topics in nearly 25 million news items published by two American national newspapers and four international wire services over the past four decades. We found vanishingly low levels of attention to pollinator population topics relative to coverage of climate change, which we use as a comparison topic. In the most recent subset of ∼10 million stories published from 2007 to 2019, 1.39% (137,086 stories) refer to climate change/global warming while only 0.02% (1,780) refer to pollinator populations in all contexts, and just 0.007% (679) refer to pollinator declines. Substantial increases in news attention were detectable only in US national newspapers. We also find that, while climate change stories appear primarily in newspaper "front sections," pollinator population stories remain largely marginalized in "science" and "back section" reports. At the same time, news reports about pollinator populations increasingly link the issue to climate change, which might ultimately help raise public awareness to effect needed policy changes.
尽管昆虫生物量和多样性的广泛减少引起了科学界的广泛关注,但尚不清楚为公众服务的信息来源是否也更加关注传粉媒介的减少。研究新闻对传粉媒介种群危机的关注模式,也有助于提高人们对除授粉以外的为生态系统提供服务的昆虫物种减少的重要性的认识。我们使用伊利诺伊大学厄巴纳-香槟分校克莱恩先进社会研究中心开发的全球新闻索引,追踪了两家美国全国性报纸和四家国际通讯社在过去四十年中发布的近 2500 万条新闻中与传粉媒介主题相关的新闻报道。我们发现,与气候变化的报道相比,传粉媒介种群主题的报道几乎没有得到关注。气候变化是我们用作比较主题的报道。在最近的约 1000 万条故事中,从 2007 年到 2019 年出版,只有 0.02%(1780 篇)涉及所有情况下的传粉媒介种群,而只有 0.007%(679 篇)涉及传粉媒介的减少,这仅占 0.02%(1780 篇)。只有在美国全国性报纸中,新闻关注度的显著增加才是可以检测到的。我们还发现,虽然气候变化的报道主要出现在报纸的“头版”,但传粉媒介种群的报道在“科学”和“后版”的报道中仍然处于次要地位。与此同时,关于传粉媒介种群的新闻报道越来越多地将这一问题与气候变化联系起来,这最终可能有助于提高公众意识,从而推动所需的政策变革。
