All measurements were made by members of the project. The experiments were carried out in the UKCEH Bangor Air Pollution Facility. Work was funded by the UK Centre for Ecology & Hydrology under the Natural Environment Research Council (UK) grant/award NEC05574.\n\nFor L. hispidus a lower leaf cover was observed with elevated ozone, and there was an increase in litter with added nitrogen. For S. pratensis, elevated ozone reduced flowering and increased foliar damage. Increased litter and accelerated winter die-back with both ozone and nitrogen were also recorded for S. pratensis.\nThese effects have implications for inter- and intra-specific competition, seed establishment, nutrient cycling, as well as the provision of general pollinator resources and highlight the need for concerted action to reduce pre-cursor ozone emissions to go alongside habitat management efforts to protect biodiversity.","distributionFormats":[{"name":"Comma-separated values (CSV)","type":"text/csv","version":"unknown"}],"distributorContacts":[{"organisationName":"NERC EDS Environmental Information Data Centre","organisationIdentifier":"https://ror.org/04xw4m193","role":"distributor","email":"info@eidc.ac.uk"}],"funding":[{"funderName":"Natural Environment Research Council","funderIdentifier":"https://ror.org/02b5d8509","awardTitle":"Natural Environment Research Council (UK) grant/award ","awardNumber":"NEC05574","orcid":false,"ror":true}],"id":"382baaf2-7795-4aa8-a434-56c9e6bd1516","incomingCitationCount":1,"incomingCitations":[{"description":"Holder, A., Hayes, F., Sharps, K., & Harmens, H.

Plants were exposed to low, medium and high ozone treatments over three growing seasons (May to September 2016-2018, treatment means: 24, 40 and 57 parts per billion, respectively), with and without the addition of nitrogen (40 kg ha-1 yr-1) during the first year.  Irrigation occurred naturally from precipitation, and no supplementary watering was required apart from that associated with the nitrogen addition.\n\nLight-saturated photosynthesis and stomatal conductance was recorded on healthy leaves using a LI-COR 6400XT. The chlorophyll index was measured on healthy leaves using an Opti-Sciences CCM200 meter. Plants were oven-dried at 60 degrees Celsius to determine dry weight. Ground cover was determined from grids (containing 100 squares) overlain onto photographs of the plant blocks, with total leaf area and the proportion of damaged leaves assessed.\n\nData was recorded onto field sheets and transferred to Excel sheets and subsequently exported to comma separated value files for deposit into the EIDC.","metadataDate":"2026-06-29T18:12:54","notGEMINI":false,"onlineResources":[{"url":"https://data-package.ceh.ac.uk/data/382baaf2-7795-4aa8-a434-56c9e6bd1516","name":"Download the data","description":"Download a copy of this data","function":"download","type":"OTHER"},{"url":"https://data-package.ceh.ac.uk/sd/382baaf2-7795-4aa8-a434-56c9e6bd1516.zip","name":"Supporting information","description":"Supporting information available to assist in re-use of this dataset","function":"information","type":"OTHER"}],"pointsOfContact":[{"familyName":"Holder","givenName":"A.J.","organisationName":"UK Centre for Ecology & Hydrology","organisationIdentifier":"https://ror.org/00pggkr55","role":"pointOfContact","email":"enquiries@ceh.ac.uk","address":{"deliveryPoint":"Environment Centre Wales, Deiniol Road","city":"Bangor","administrativeArea":"Gwynedd","postalCode":"LL57 2UW","country":"United Kingdom"},"fullName":"Holder, A.J.","pointOfContact":"UK Centre for Ecology & Hydrology"}],"publicationDate":"2020-11-12T00:00:00.000Z","publishers":[{"organisationName":"NERC Environmental Information Data Centre","organisationIdentifier":"https://ror.org/04xw4m193","role":"publisher","email":"info@eidc.ac.uk"}],"resourceIdentifiers":[{"code":"https://catalogue.ceh.ac.uk/id/382baaf2-7795-4aa8-a434-56c9e6bd1516"},{"code":"10.5285/382baaf2-7795-4aa8-a434-56c9e6bd1516","codeSpace":"doi"}],"resourceMaintenance":[{"frequencyOfUpdate":"notPlanned"}],"resourceType":{"value":"dataset"},"responsibleParties":[{"familyName":"Holder","givenName":"A.J.","organisationName":"UK Centre for Ecology & Hydrology","organisationIdentifier":"https://ror.org/00pggkr55","role":"author","email":"enquiries@ceh.ac.uk","fullName":"Holder, A.J."},{"familyName":"Hayes","givenName":"F.","organisationName":"UK Centre for Ecology & Hydrology","organisationIdentifier":"https://ror.org/00pggkr55","role":"author","email":"enquiries@ceh.ac.uk","nameIdentifier":"https://orcid.org/0000-0002-1037-5725","fullName":"Hayes, F."},{"familyName":"Sharps","givenName":"K.","organisationName":"UK Centre for Ecology & Hydrology","organisationIdentifier":"https://ror.org/00pggkr55","role":"author","email":"enquiries@ceh.ac.uk","nameIdentifier":"https://orcid.org/0000-0003-3265-1505","fullName":"Sharps, K."},{"familyName":"Holder","givenName":"A.J.","organisationName":"UK Centre for Ecology & Hydrology","organisationIdentifier":"https://ror.org/00pggkr55","role":"pointOfContact","email":"enquiries@ceh.ac.uk","address":{"deliveryPoint":"Environment Centre Wales, Deiniol Road","city":"Bangor","administrativeArea":"Gwynedd","postalCode":"LL57 2UW","country":"United Kingdom"},"fullName":"Holder, A.J.","pointOfContact":"UK Centre for Ecology & Hydrology"},{"organisationName":"NERC Environmental Information Data Centre","organisationIdentifier":"https://ror.org/04xw4m193","role":"publisher","email":"info@eidc.ac.uk"},{"organisationName":"UK Centre for Ecology & Hydrology","organisationIdentifier":"https://ror.org/00pggkr55","role":"rightsHolder","email":"enquiries@ceh.ac.uk"},{"organisationName":"NERC EDS Environmental Information Data Centre","organisationIdentifier":"https://ror.org/04xw4m193","role":"custodian","email":"info@eidc.ac.uk"},{"familyName":"Harmens","givenName":"H.","organisationName":"UK Centre for Ecology & Hydrology","organisationIdentifier":"https://ror.org/00pggkr55","role":"author","email":"enquiries@ceh.ac.uk","nameIdentifier":"https://orcid.org/0000-0001-8792-0181","fullName":"Harmens, H."}],"rightsHolders":[{"organisationName":"UK Centre for Ecology & Hydrology","organisationIdentifier":"https://ror.org/00pggkr55","role":"rightsHolder","email":"enquiries@ceh.ac.uk"}],"spatialReferenceSystems":[{"code":"http://www.opengis.net/def/crs/EPSG/0/4326","title":"WGS 84"}],"spatialRepresentationTypes":["textTable"],"spatialResolutions":[{"distance":"1","uom":"urn:ogc:def:uom:EPSG::9001"}],"supplemental":[{"name":"Solardomes and ozone field release system website","url":"https://www.ceh.ac.uk/our-science/research-facility/solardomes-and-ozone-field-release-system","function":"website"},{"description":"Agathokleous et al.
