Recently, a new hypothesis has\u00a0been formed that air pollution could act as a further stress factor contributing towards pollinator declines.<\/p>\n<p>The mechanism\u00a0proposed is that air pollutants chemically alter, deplete or mask the volatile organic compounds (VOCs) emitted by flowers\u00a0(i.e. their floral scents), which pollinators use to locate flowers. However, prior to our study, the only evidence to support\u00a0this theory resulted from small-scale laboratory assays, and atmospheric chemistry models. Using a novel free-air\u00a0fumigation facility, we provided field-scale experimental evidence to demonstrate that even moderate increases in\u00a0the\u00a0concentration of common ground-level air pollutants (diesel exhaust and ozone) result in severe reductions in visits from\u00a0insects to flowers and consequently a reduction in successful pollination.<\/p>\n<p>This original research demonstrates that air pollutants can significantly disrupt natural ecological processes\u00a0that are critical for ecosystem functioning. The results have wide ecological ramifications, because VOCs are critical\u00a0mediators of important life events for many insect species (e.g. mate location using pheromones). The article in\u00a0Environmental Pollution has received 19 citations so far this year and has been reported domestically and internationally in\u00a0more than 80 news outlets, including Wall Street Journal, New Scientist, The Times, ABC News, ITV and BBC. It currently\u00a0has an Altmetric score of 781. As such, the article has resonated with a wide audience.<\/p>\n<p>The reviewers considered that the paper made a new and significant contribution to research. It focused on observational methods rather than underpinning mechanisms but the move away from laboratory to open field testing is novel. It was not entirely clear at which scale of the landscape\u00a0the results apply (e.g., farm level, regional\u00a0level etc) \u2013 alternatively, how\u00a0the experimental design would need to calibrated for different\u00a0scales. Mitigation measures or policy\u00a0implications\/interventions not considered. The relevance and\u00a0potential impact of the research is very high in terms of the impact on\u00a0agricultural\u00a0production and its sustainability.<\/p>\n<p><a href=\"https:\/\/www.reading.ac.uk\/sustainable-land-management\/our-staff\/james-ryalls\">James Ryalls<\/a>\u00a0is a Research Fellow in the Centre for Agri-Environmental Research at the University of Reading and winner of the University\u2019s 2023 Research Output Prize (Agriculture, Food &amp; Health theme) for his paper as first author in<em>\u00a0Environmental Pollution<\/em>,\u00a0<a href=\"https:\/\/www.sciencedirect.com\/science\/article\/pii\/S0269749122000616?via%3Dihub\">\u2018Anthropogenic air pollutants reduce insect-mediated pollination services\u2019<\/a>.[\/vc_column_text][vc_column_text]Find out more about this work on <a href=\"https:\/\/research.reading.ac.uk\/research-blog\/the-effects-of-air-pollution-on-pollinators\/\">Connecting Research<\/a>.[\/vc_column_text][\/vc_column][\/vc_row]<\/p>\n","protected":false},"excerpt":{"rendered":"<p>[vc_row][vc_column][vc_column_text] Anthropogenic air pollutants reduce insect-mediated pollination services Declines in the numbers and diversity of insects that pollinate our food crops and wild plants are currently considered to be the&#8230;<a class=\"read-more\" href=\"&#104;&#116;&#116;&#112;&#115;&#58;&#47;&#47;&#114;&#101;&#115;&#101;&#97;&#114;&#99;&#104;&#46;&#114;&#101;&#97;&#100;&#105;&#110;&#103;&#46;&#97;&#99;&#46;&#117;&#107;&#47;&#101;&#110;&#103;&#97;&#103;&#101;&#109;&#101;&#110;&#116;&#45;&#97;&#110;&#100;&#45;&#105;&#109;&#112;&#97;&#99;&#116;&#47;&#114;&#101;&#115;&#101;&#97;&#114;&#99;&#104;&#45;&#111;&#117;&#116;&#112;&#117;&#116;&#45;&#112;&#114;&#105;&#122;&#101;&#45;&#50;&#48;&#50;&#51;&#45;&#106;&#97;&#109;&#101;&#115;&#45;&#114;&#121;&#97;&#108;&#108;&#115;&#47;\">Read More ><\/a><\/p>\n","protected":false},"author":469,"featured_media":1885,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"_monsterinsights_skip_tracking":false,"_monsterinsights_sitenote_active":false,"_monsterinsights_sitenote_note":"","_monsterinsights_sitenote_category":0,"__cvm_playback_settings":[],"__cvm_video_id":"","footnotes":""},"categories":[206],"tags":[100],"coauthors":[90],"class_list":["post-1828","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-ecr-output-prize-2023","tag-sustainable-agriculture-food-systems"],"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v21.8.1 -
