Summary: This study investigates the relationship between hydroscape area (HA) and climatic conditions and functional traits across 10 Eucalyptus species in the Hawaiian Islands. The results show that HA decreases with increased P/E-p, and larger HA coincides with species that have higher sensitivity to mesophyll photosynthetic capacity.

Summary: The study revealed that under drought conditions, stomatal conductance (g(s)) was more sensitive than mesophyll conductance (g(m). ABA was involved in coordinating reductions of g(s) and g(m), thereby regulating net photosynthesis (A(n)) and intrinsic water use efficiency (WUEi).

Summary: Potassium is an essential nutrient for plants and its deficiency can impact the photochemical phase of photosynthesis, leading to rearrangement of PSII complexes and increased energy dissipation. Different hybrid cultivars of radish show varying growth and photosynthetic characteristics under potassium deficiency, with some cultivars exhibiting tolerance.

Summary: As the frequency of heatwaves increases, they are more likely to coincide with other disturbances like insect defoliation. This study found that defoliation exhibited strong thermal acclimation during a simulated spring heatwave, while stomatal conductance and net photosynthesis of oak saplings increased. Heatwave did not affect leaf area recovery or carbohydrate storage of defoliated saplings, but reflush leaves had higher minimum leaf conductance than undefoliated leaves, and this effect was amplified by the heatwave. Higher minimum leaf conductance was associated with higher daytime stomatal conductance and a lower turgor loss point.

Summary: Leaf rolling is a physiological response to drought that can reduce water loss, but its contribution to drought tolerance is uncertain. This study evaluated leaf rolling in four rice genotypes subjected to drought and found that stomatal conductance decreased before complete closure of the stomata, leading to leaf rolling. Rolled leaves had significantly reduced water loss compared to flattened leaves. Leaf rolling was found to be linked to drought avoidance and tolerance traits, making it a potential phenotypic trait for rice breeding in future drought scenarios.

Summary: Leaf rolling is a physiological response to drought that helps reduce water loss. The study found that leaves roll up before the stomata close completely during drought, which effectively reduces water loss. Additionally, leaf rolling is closely related to gas exchange and leaf hydraulic conductance in plants.

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: This study quantifies agricultural drought severity for spring wheat at the jointing stage by analyzing the response of leaf physiological parameters to progressive soil drying. Five stages of agricultural drought were defined based on the different response mechanisms of the net photosynthesis rate to soil drying. This approach of quantifying agricultural drought severity during the crop growth period can be useful for modeling crop growth and development under water deficit conditions.

Summary: Drought has a significant impact on crop growth, and understanding the short-term and long-term responses of crops to drought is crucial. Field data analysis showed that different water supply treatments strongly influenced leaf and canopy gas exchange, as well as cumulative growth in winter wheat and maize. The long-term morphological responses of winter wheat played a larger role in regulating transpiration and assimilation rates, while maize exhibited physiological advantages and morphological adjustments under drought conditions. Improved modeling of gas exchange and crop growth should consider dynamic changes in leaf area and stomatal regulation.

Summary: The study found that nocturnal stomatal conductance varies greatly among different tree species under wet soil conditions, with Populus tremula showing the highest conductance and Quercus robur the lowest. As drought progressed, species tended to close their stomata at night, leading to disappearance of differences between anisohydric and isohydric species.

Summary: The autochthonous mycorrhizal consortium Rhizolive significantly reduced disease severity and incidence, as well as defoliation rate, in olive trees infected with Verticillium dahliae. This consortium enhanced lignin deposition and phenylpropanoid pathway activity, contributing to the suppression of the pathogen.

Summary: This study provides insights into the effects of arbuscular mycorrhizal fungi (AMF), vermicompost (Vc), and their combination on growth and biochemical responses of prickly pear under severe water stress. The results demonstrate that the use of AMF and Vc can effectively mitigate growth limitations and improve physiological and biochemical parameters of prickly pear under drought stress. The AMF + Vc treatment showed the highest AMF colonization and growth parameters under drought stress conditions. The application of these biostimulants increased physiological and biochemical parameters, while reducing levels of malondialdehyde (MDA) and hydrogen peroxide (H2O2) in plants, particularly in the AMF + Vc treatment.

Summary: This study proposes an eco-efficient scheme (EES) that is both selective and environmentally viable, and compares it to a conventional activated sludge scheme (CAS). The results show that CAS and EES have optimal process operation and significant differences in organic load and nutrient removal efficiencies. Statistical analysis also reveals a positive correlation between influent/effluent wastewater parameters, performance indicators, and process configuration. The eco-efficient process exhibits promising potential as a sustainable and eco-friendly technology.
