“…Payne et al (2011) identified O 3 as a key driver of compositional changes in species in British acid grassland, in addition to N deposition, although it was not associated with a reduction in species richness or diversity indices. In general, field evidence for compositional changes remains very scarce, and most evidence for the potential impact of O 3 on plant diversity therefore rests on data from controlled experiments with either artificial model communities or intact ecosystems in which O 3 levels are varied while other factors are kept constant (Weigel, Bergmann, & Bender, 2015).…”

Risks associated with exposure of individual plant species to ozone (O3) are well documented, but implications for terrestrial biodiversity and ecosystem processes have received insufficient attention. This is an important gap because feedbacks to the atmosphere may change as future O3 levels increase or decrease, depending on air quality and climate policies. Global simulation of O3 using the Community Earth System Model (CESM) revealed that in 2000, about 40% of the Global 200 terrestrial ecoregions (ER) were exposed to O3 above thresholds for ecological risks, with highest exposures in North America and Southern Europe, where there is field evidence of adverse effects of O3, and in central Asia. Experimental studies show that O3 can adversely affect the growth and flowering of plants and alter species composition and richness, although some communities can be resilient. Additional effects include changes in water flux regulation, pollination efficiency, and plant pathogen development. Recent research is unraveling a range of effects belowground, including changes in soil invertebrates, plant litter quantity and quality, decomposition, and nutrient cycling and carbon pools. Changes are likely slow and may take decades to become detectable. CESM simulations for 2050 show that O3 exposure under emission scenario RCP8.5 increases in all major biomes and that policies represented in scenario RCP4.5 do not lead to a general reduction in O3 risks; rather, 50% of ERs still show an increase in exposure. Although a conceptual model is lacking to extrapolate documented effects to ERs with limited or no local information, and there is uncertainty about interactions with nitrogen input and climate change, the analysis suggests that in many ERs, O3 risks will persist for biodiversity at different trophic levels, and for a range of ecosystem processes and feedbacks, which deserves more attention when assessing ecological implications of future atmospheric pollution and climate change.

“…Two of the factors that influence sensitivity to ozone are control of the flux of ozone into the leaf, and the capacity for detoxification and repair processes (Wieser and Matyssek, 2007). Ozone damage can trigger a cascade of defence reactions, which can further affect plant responses including growth or resource partitioning (Weigel et al, 2015). Many species of (semi-)natural vegetation are known to be sensitive to ozone pollution, based on ozone-exposure experiments and can show significant impacts with average ozone concentrations less than 70 pbb (e.g.…”

“…Whilst this topic rapidly became the object of much research in the 1980s [39], the improved forest health conditions in the following decade, likely due to reduced air pollution and rarer acid rain events, both in North America and in Europe, resulted in a decreased use of this keyword. However, research on the links between forest health and air/soil pollution continued after the 1980s [40][41][42]. The forest damages due to air pollution currently observed in China [43][44][45] do not seem to be leading to a resurgence in the literature of the use of the term "Waldsterben".…”

Abstract:Maintaining forest health is a worldwide challenge due to emerging tree diseases, shifts in climate conditions and other global change stressors. Research on forest health is thus accumulating rapidly, but there has been little use of scientometric approaches in forest pathology and dendrology. Scientometrics is the quantitative study of trends in the scientific literature. As with all tools, scientometrics needs to be used carefully (e.g., by checking findings in multiple databases) and its results must be interpreted with caution. In this overview, we provide some examples of studies of patterns in the scientific literature related to forest health and tree pathogens. Whilst research on ash dieback has increased rapidly over the last years, papers mentioning the Waldsterben have become rare in the literature. As with human health and diseases, but in contrast to plant health and diseases, there are consistently more publications mentioning "tree health" than "tree disease," possibly a consequence of the often holistic nature of forest pathology. Scientometric tools can help balance research attention towards understudied emerging risks to forest trees, as well as identify temporal trends in public interest in forests and their health.
