Growth and physiological measurements of Leontodon hispidus and Succisa pratensis after ozone exposure and elevated nitrogen input from an ozone field release system, North Wales, 2016-2018
The data presented are growth and physiological measurements from an ozone exposure experiment, during which grassland forbs, Leontodon hispidus and Succisa pratensis were exposed to low, medium and high ozone treatments over three growing seasons, using an outdoor Free Air Ozone Enrichment system, and with and without the addition of nitrogen during the first year. The plants were planted in April 2016 and were exposed to Low, Medium and High ozone treatments over three growing seasons (May to September 2016-2018). Measurements were taken of light-saturated photosynthesis, stomatal conductance, chlorophyll index, number of flowering stems, leaf ground cover, and the dried weight of litter. 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. For 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. These 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.

The plants were planted directly into the ground in 1m separate square blocks, with the two species alternating in a Latin square design, within nine Free Air Ozone Enrichment (FAOE) rings (4m diameter). 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. Light-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. Data was recorded onto field sheets and transferred to Excel sheets and subsequently exported to comma separated value files for deposit into the EIDC.
