Summary: Compared to evergreens, deciduous tree species have higher photosynthetic capacity, which is evolutionally associated with increased stomatal conductance and mesophyll conductance. The difference in mesophyll conductance between the two groups is mainly determined by mesophyll and chloroplast surface area exposed to intercellular air space. Deciduous trees also display a faster induction speed of photosynthesis, mainly due to the maintenance of higher stomatal conductance. These cell-level traits allow deciduous trees to achieve carbon gains comparable to evergreen species despite their shorter growing season.

Summary: This study found a decreasing trend in ozone exposure at Yellowstone National Park and no trend at Grand Teton National Park using different metrics. The traditional method and the Big-leaf model showed discrepancies in estimating high stomatal ozone flux values. A new multivariate function developed through machine learning improved the estimation of stomatal ozone flux variability.

Summary: Dry deposition is a significant sink for tropospheric ozone, influenced by the spatial structure in turbulence which affects the efficiency of leaf ozone uptake. Organized turbulence separates areas of efficient leaf uptake from areas of high or low ozone mixing ratios, suggesting that the impact of organized turbulence on dry deposition can be disregarded in dry deposition parameterizations and interpretations of ozone flux observations.

Summary: Deforestation has led to the presence of heterogeneous patches of old-growth and secondary forests in Southeast Asia, posing challenges for understanding the hydrological and carbon cycles. However, research suggests that forest succession may not directly influence gas exchange, rather, canopy development associated with forest stage appears to have the main effect.

Summary: This study compared the leaf hydraulic functionality of co-occurring evergreen and deciduous shrubs grown on Olympus Mountain. The results demonstrated different hydraulic tactics between the deciduous and evergreen shrubs, with higher hydraulic conductance and lower stomatal conductance observed in the deciduous plants. Positive correlations were also found between water potential and transpiration in the deciduous shrubs.

Summary: Stomata play a crucial role in regulating the exchange of trace gases between terrestrial vegetation and the atmosphere, impacting atmospheric composition and climate. Vegetation acts as a major sink for ground-level ozone, with the rate of dry deposition largely controlled by stomatal diffusion. The choice of stomatal conductance parameterization is critical for accurate quantification of ozone deposition rates.

Summary: This study investigates the efficiency of nitrogen (N) amendments in managing ozone (O-3) stress in two varieties of Indian bean. The results show that Kashi Sheetal is more tolerant to O-3 compared to Kashi Harittima. Nitrogen amendments are effective in partially alleviating O-3 stress, with N2 being the most effective dose. Kashi Sheetal is determined to be O-3 tolerant due to higher levels of endogenous H2O2 accumulation and enzymatic antioxidant contents.

Summary: This study found evidence of hydraulic vulnerability segmentation (HVS) in compound-leaved tree species during drought, with stems showing higher embolism resistance compared to petioles and leaflets. The coordinated variation in embolism vulnerability between organs suggests that shedding more expendable organs such as leaflets and petioles can protect the hydraulic system of stems, enabling compound-leaved trees to better withstand drought stress.

Summary: This study investigated how tropical trees acclimate to long-term drought stress by measuring various parameters such as photosynthetic capacity and NSC storage. The results showed that surviving trees after drought treatment exhibited altered strategies for carbon storage and use, with changes mainly observed in trees with canopies exposed to high radiation. This study emphasizes the importance of understanding the impact of full-canopy light environment on long-term responses to drought stress in tropical forests.

Summary: The study found that deciduous trees maintain a high level of nitrogen uptake throughout the non-growing season, challenging the traditional view that deciduous trees remain dormant during this time. Soil nitrogen transformation remained active in winter, with microbial nitrogen immobilization reaching its peak in late winter. Evergreen and deciduous trees showed higher uptake rates for NH4+ and glycine than NO3- and tyrosine, while deciduous shrubs and herbs preferred NO3- over other forms of nitrogen.

Summary: Urban extreme high temperatures, harmful to human health and plants, can be alleviated by trees through transpiration and shading. A newly developed model integrating soil water balance and energy calculations evaluates the physiological responses and microclimate effects of street trees on temperature regulation. The shading effect of trees contributes the most to temperature reduction at midday.

Summary: This study shows that warmer spring temperatures cause earlier stem diameter growth in deciduous trees, but have no consistent effect on growing season length, maximum growth rates, or annual growth. Furthermore, tree-ring chronologies indicate that annual ring width is more sensitive to temperatures during the peak growing season than in the spring. These findings suggest that warmer spring temperatures are unlikely to increase woody productivity enough to strengthen the long-term CO2 sink of temperate deciduous forests.

Summary: Date palms are economically important species in hot arid regions but little is known about their sensitivity to O-3 pollution. Our study found that resistance mechanisms in date palms against elevated O-3 include restricting stomatal O-3 uptake and enhancing metabolism for detoxification and repair. Despite impacts on photosynthesis, most growth parameters were not affected by O-3 exposure.

Summary: Elevated O-3, particularly in interaction with N and/or P levels, induced tissue- and cell type-specific changes in the anatomical structure of poplar roots. The effects of O-3 in combination with N and P on anatomical structure and hydraulic properties were investigated, revealing complex interactions between these factors. Elevated O-3 suppressed the effects of N and P on vessel grouping and size, indicating a need for further research on carbon-saving mechanisms in response to environmental stressors.

Summary: Chronic ozone exposure selectively disrupts metabolic processes in the roots rather than the shoot, affecting mineral uptake and partitioning between roots and shoots. However, there were no significant changes in total carbon and nitrogen concentrations and their partitioning between different metabolic pools. The effects of chronic ozone exposure on mineral acquisition and partitioning between leaves and roots are discussed.

Summary: This study tested a new phenotypic ozone index (LIF) for assessing the tolerance capacity of vegetation to O-3 stress, based on measurements of stomatal O-3 flux and Leaf Mass per Area (LMA). The results showed a strong correlation between LIF and visible foliar injury (VFI), indicating that LIF is a promising index for evaluating O-3 risk potential for forest woody species.

Summary: The study reveals that the concentration of tropospheric ozone exceeds the safety levels in tropical and subtropical regions, posing a threat to crops, forests, and human health. The ozone concentration exceeds the allowed range in certain areas, negatively impacting human health, forest productivity, and food security. Ozone risk assessment includes concentration-based and flux-based metrics.

Summary: The functional responses of two Mediterranean pine species, P. halepensis and P. pinea, to long-term ozone exposure were examined. It was found that P. halepensis, with thin needles, was sensitive to ozone and showed a significant decrease in photosynthesis, while P. pinea, with thicker needles, was resistant to ozone and did not show clear effects on photosynthesis. These findings are important for understanding the response mechanisms and adaptability of Mediterranean pine forests to ozone pollution.

Summary: This study compared the sustainability of active monitoring (AM) and passive monitoring (PM) of phytotoxic tropospheric ozone in forest sites. The results showed that AM had lower environmental, economic, and social costs compared to PM, leading to savings in the long term and suggesting that passive monitoring is not environmentally sustainable, especially over extended periods.
