“…To incorporate the O 3 effects on tree growth into UVAFME, we first classify the 32 species into three categories based on their relative sensitivity to O 3 stress: resistant, intermediate, and sensitive ( Supplementary Table 1 ). This categorization derives from the current literatures including review studies 4 7 8 43 44 and reports on individual species 45 46 47 48 49 50 51 . A growth reduction of 0, 10%, and 20% is exerted on resistant, intermediate and sensitive species, respectively (For a validity check of these specific reduction values, see Supplementary Fig.…”

Tropospheric ozone is a serious air-pollutant, with large impacts on plant function. This study demonstrates that tropospheric ozone, although it damages plant metabolism, does not necessarily reduce ecosystem processes such as productivity or carbon sequestration because of diversity change and compensatory processes at the community scale ameliorate negative impacts at the individual level. This study assesses the impact of ozone on forest composition and ecosystem dynamics with an individual-based gap model that includes basic physiology as well as species-specific metabolic properties. Elevated tropospheric ozone leads to no reduction of forest productivity and carbon stock and to increased isoprene emissions, which result from enhanced dominance by isoprene-emitting species (which tolerate ozone stress better than non-emitters). This study suggests that tropospheric ozone may not diminish forest carbon sequestration capacity. This study also suggests that, because of the often positive relationship between isoprene emission and ozone formation, there is a positive feedback loop between forest communities and ozone, which further aggravates ozone pollution.

“…L. tulipifera has been used as a bioindicator of O 3 in eastern US forests for a long time due to its sensitivity to O 3 (Davis and Skelly 1992). However, no information is available on L. chinense, the other species within the genus Liriodendron, in response to O 3 .…”

Effects of ozone exposure on growth and photosynthesis of the seedlings of Liriodendron chinense (Hemsl.) Sarg, a native tree species of subtropical China

Little is known about the response of trees to elevated ozone (O 3 ) in the subtropical region of China, where ambient O 3 concentrations are high enough to damage plants. In this study, pigment content, gas exchange and chlorophyll (Chl) a fluorescence in leaves of Liriodendron chinense (Hemsl.) Sarg seedlings, a deciduous broadleaf tree species native in subtropical regions, were investigated at 15, 40, and 58 days after O 3 fumigation (DAF) at a concentration of 150 mm 3 m -3 (E-O 3 ). At the end of experiment, seedlings were harvested for biomass measurement. E-O 3 caused visible injuries on the mature leaves e.g. necrotic patches and accelerated early defoliation. Relative to the charcoal-filtered air (CF) treatment, E-O 3 significantly decreased shoot and root biomass, pigment content, light-saturated net photosynthesis (P Nsat ), stomatal conductance (g s ), maximum rate of carboxylation (V cmax ) , photochemical quenching coefficient (q p ) and effective quantum yield of PSII photochemistry (Ф PSII ), and also caused a slight reduction in relative increase of basal diameter. Therefore, L. chinense can be assumed to be an O 3 -sensitive tree species, which will be threatened by increasing ambient O 3 concentrations in China.
