Surface Ozone in Northern Scandinavia and Implications on Local Vegetation - A Case Study.
Show summary
The Arctic biosphere is subject to comprehensive changes induced by climate change. The highly specialized subartic vegetation will be challenged by both, changing environmental conditions as well as further interference through human activity. Permission of exploitation of natural resources in the Artic is likely to increase the levels of air pollutants which are precursors to ozone.
n the course of our project (OzoNorClim: The Double Punch), we had an ozone monitor installed at the Norwegian Institute for Bioeconomic Research (NIBIO) Svanhovd Research Station operated by the Norwegian Institute for Air Research (NILU). In 2018, a long-lasting heatwave accompanied by extensive forest fires across Europe and Scandinavia enhanced surface ozone concentrations by about 2 ppt above the climatological mean in Northern Scandinavia. Ozone sensitive glover species in the ozone garden at Svanhovd showed clear signs of ozone damage in 2018 but not in 2019. We study these two years as example for probable future scenarios in which both heat stress and ozone stress affect vegetation negatively. We look at the corresponding surface ozone concentrations, accumulated ozone dose, and implications on natural and semi-natural vegetation especially in the Pasvik valley in Northern Norway, put these in a larger regional context, and give an outlook on further modelling work.

Plant responses to ozone stress under northern light conditions.
Show summary
Ground level ozone is a major air pollutant affecting plants worldwide by reducing crop productivity and the growth and diversity of natural vegetation. Ozone is taken up into the leaves causing oxidative tissue damage, premature leaf aging and visible lesions such as flecking, bronzing and necrotic spots (Krupa et al. 2001). Plants at northern latitudes often show more ozone injury than plants at lower latitudes, despite lower ambient ozone concentrations. It has been postulated that the summer nights at high latitudes are too short to allow sufficient recovery of ozone injury. Another hypothesis is that the dim light during northern summer nights interferes with repair of ozone damage (Vollsnes et al. 2009). Experiments were performed to identify which wavelength regions of light and hence photoreceptors were involved in altering ozone repair capacity. The results point to phytochrome which is involved in plant development, photomorphogenesis and photoperiodism. It appears that phytochrome mediated processes activated by light during nighttime impaired ozone repair. It was also investigated whether the increased ozone sensitivity during northern summer nights was dependent on latitude of origin of the species. Ozone sensitivity of northern species adapted to northern conditions should be unaffected by northern summer nights whereas more southern species should show increased sensitivity. This does not appear to be the case. Rather, the response is species dependent suggesting that constitutive defence prior to ozone exposure is important.

Detecting and quantifying ozone damage on leaves.
Show summary
Ground level ozone is one of the most important air pollutants damaging plants worldwide. Ozone causes premature leaf aging, leaf visible lesions, necrotic spots and damages leaf temperature regulation. Determining if and how much of a leaf is damaged, is usually done by visual inspection which is time-consuming and observer dependent. The aim of this study was to evaluate methods for automated classification of leaves as healthy or damaged using different feature detectors and PLS Discriminant Analysis. Classification performance depended upon the choice of feature detector and image colour channel. The study shows that it should be possible to develop automated classification of healthy and damaged leaves.

A method for visualising ozone damage on clover leaves.
Show summary
Ground level ozone is one of the most important air pollutants damaging plants worldwide. Ozone causes premature leaf aging, leaf visible lesions and necrotic spots and damages leaf temperature regulation. Infrared imaging was used to detect leaf temperature changes. Visible images were taken to capture leaf lesions and necrosis. Feature detectors were extracted from the images and analysed with multivariate statistics. All feature detectors were quite good at separating injured and healthy leaves.
