Abstract:
Air pollution has the potential to disrupt ecologically- and economically-beneficial services provided by invertebrates, including pollination and natural pest regulation. To effectively predict and mitigate this disruption requires an understanding of how the impacts of air pollution vary between invertebrate groups. Here we conduct a global meta-analysis of 120 publications comparing the performance of different invertebrate functional groups in unpolluted and polluted atmospheres. We focus on the pollutants ozone, nitrogen oxides, sulfur dioxide and particulate matter. We show that beneficial invertebrate performance is reduced by air pollution, whereas the performance of plant pest invertebrates is not significantly affected. Ozone pollution has the most detrimental impacts, and these occur at concentrations below national and international air quality standards. Changes in invertebrate performance are not dependent on air pollutant concentrations, indicating that even low levels of pollution are damaging. Predicted increases in tropospheric ozone could result in unintended consequences to global invertebrate populations and their valuable ecological services.
摘要:
空气污染有可能破坏无脊椎动物提供的生态和经济上有益的服务,包括授粉和自然害虫调控。为了有效地预测和减轻这种破坏,需要了解无脊椎动物群体之间空气污染的影响如何变化。在这里,我们对120种出版物进行了全球荟萃分析,比较了不同无脊椎动物官能团在未污染和污染大气中的表现。我们关注污染物臭氧,氮氧化物,二氧化硫和颗粒物。我们表明,空气污染会降低有益的无脊椎动物性能,而植物害虫无脊椎动物的性能没有显着影响。臭氧污染具有最有害的影响,这些情况的浓度低于国家和国际空气质量标准。无脊椎动物性能的变化不取决于空气污染物浓度,表明即使是低水平的污染也是有害的。对流层臭氧的预测增加可能会对全球无脊椎动物种群及其宝贵的生态服务造成意想不到的后果。
