“…To date, research has focused on the O 3 effect on the defensive capacity of plants, as suppression of defensive capacity leads to increased susceptibility to damage by insects. In recent research, serious insect grazing damages on avenue trees were found at relatively low O 3 concentrations (urban centers) in northeast Asia, but such damages were not found on the same species at suburban sites with higher O 3 levels (Takahashi et al 2020). Plant-insect communication via biogenic volatile organic compounds (BVOCs) should be considered as a possible explanation for these observations (Agathokleous et al 2020;Masui et al 2020).…”

Ozone disrupts the communication between plants and insects in urban and suburban areas: an updated insight on plant volatiles

Plant–insect interactions are basic components of biodiversity conservation. To attain the international Sustainable Development Goals (SDGs), the interactions in urban and in suburban systems should be better understood to maintain the health of green infrastructure. The role of ground-level ozone (O3) as an environmental stress disrupting interaction webs is presented. Ozone mixing ratios in suburbs are usually higher than in the center of cities and may reduce photosynthetic productivity at a relatively higher degree. Consequently, carbon-based defense capacities of plants may be suppressed by elevated O3 more in the suburbs. However, contrary to this expectation, grazing damages by leaf beetles have been severe in some urban centers in comparison with the suburbs. To explain differences in grazing damages between urban areas and suburbs, the disruption of atmospheric communication signals by elevated O3 via changes in plant-regulated biogenic volatile organic compounds and long-chain fatty acids are considered. The ecological roles of plant volatiles and the effects of O3 from both a chemical and a biological perspective are presented. Ozone-disrupted plant volatiles should be considered to explain herbivory phenomena in urban and suburban systems.

“…On the other hand, particulate matter that floats in air particles would act as a physical barrier for optimal photosynthesis, as the particle matter clogs the stomata openings and shields the leaves from receiving maximum sunlight. This is evident in the research conducted by Takahashi, et al [71] where they concluded that the tree and forest deterioration is due to SO2 and NOx. Even though ecosystems thrive in optimal levels of nitrogen, excess nitrogen (N) results in biodiversity loss and increased stress on tree vitality.…”

Water, Soil and Air Pollutants’ Interaction on Mangrove Ecosystem and Corresponding Artificial Intelligence Techniques Used in Decision Support Systems - A Review

et al. 2021

The feasibility of artificial intelligence (AI) as a predictive model for thorough efficacy analysis on environmental pollution applied on mangrove forests are discussed. Mangrove forests are among the most productive and biological diverse ecosystems on the planet. However, due to environmental pollution and climate change, mangrove forests are in serious decline. Despite crucial issues pertaining mangrove forests, the law enforcement on the ecosystem is still dubious due to the lack of evidence and data that could provide accurate analysis and prediction. The main highlight of this review elaborates on pollutant markers in soil, water, and air, by correlating these three aspects to the sustainability of mangrove ecosystem. The research gap identified from this review suggests the application of an integrated environmental prediction system for practical environmental insights. A predictive model for environmental decision-making could be developed by integrating meteorological, climatological, hydrological, atmospheric, and heavy metal concentration to understand the interaction between each factor for an efficient solution of pollutant reduction scheme involving mangrove ecosystems. INDEX TERMS Mangrove estuarine; pollutant interaction; environmental quality modelling; integrated environmental decision system.

“…The mechanism of these pollutants reaching mountainous areas has been examined based on analyses of aerosols (Suzuki et al 2008), rain and fog (Uehara et al 2015), snow (Yamamoto et al 2018), lake sediments (Hosono et al 2016), and alpine vegetation (Oishi 2018(Oishi , 2019. Notably, transboundary pollutants are signi cantly associated with forest decline in Japan, having harmful effects on trees by injuring plant tissues, inhibiting the growth, and accelerating senescence (Takahashi et al 2020). Despite these risks, pollutant monitoring in Japan's mountainous areas remains limited owing to the di culties of installing measuring equipment in mountainous terrane.…”

Long-range transported atmospheric pollutants (or transboundary pollutants) include trace metals with isotope ratios and compositions that vary from those of domestic pollutants, which threaten mountain ecosystems. These differences can be applied as indices (trace metal indices) to evaluate the influence of transboundary pollutants on mountain ecosystems. Mosses play important ecological functions in mountains and are sensitive to atmospheric deposition. Therefore, using these indices for moss biomonitoring can provide a more accurate indication of ecosystem health. However, few studies have examined which indices are appropriate for moss biomonitoring. In this study, the effectiveness of moss biomonitoring using trace metal indices was examined for evaluating transboundary pollutants in mountainous areas in Japan. Transboundary pollutants in these areas originate from mainland Asia and are characterized by high lead isotope ratios, lead to zinc (Pb/Zn) ratios, and arsenic to vanadium (As/V) ratios. Given that the abundance of transboundary pollutants decreases with distance from mainland Asia, moss isotope indices are also expected to vary with distance. Based on observations, Pb isotope ratios were found to decrease with distance from mainland Asia; in contrast, Pb/Zn and As/V ratios did not display any notable relationship with distance. These results are likely attributed to biological and environmental factors that affect trace metal contents in moss. Thus, moss Pb isotope ratios are useful indicators of transboundary pollutants in Japan’s mountains, offering an important tool for comparable moss biomonitoring studies in East Asia.
