Summary: Sea spray droplets play a significant role in the exchange of gases between oceans and atmosphere. Considering this spray-mediated pathway may improve the accuracy of modeling air-sea interactions and understanding the ocean's response to climate change.

Summary: This study investigates the effects of the dgt mutation on plant hydraulics and leaf gas exchange in tomato plants. The dgt mutant shows reduced vessel diameter and conduit number in petioles and stems, resulting in lower hydraulic conductivities. Interestingly, despite similar root characteristics, the dgt mutant has lower root hydraulic conductance. Additionally, the increased vein and stomatal density in the dgt mutant does not lead to higher leaf gas exchange due to compromised hydraulic efficiency.

Summary: Subtropical tree species may face severe drought stress in the future due to variable rainfall, and the ability to restore hydraulic function after drought may vary among species with different leaf habits. The links between hydraulic recovery and physiological and morphological traits related to water-carbon availability are still not well understood.

Summary: In a 58-year common garden experiment, we tested the phenological sensitivity of northern red oak populations to temperature changes and whether these differences were associated with differences in productivity and survival. We found that spring leaf out consistently advanced in warmer years, but fall phenology was less responsive to temperature changes. Southern populations had larger shifts in phenology in response to springtime warming, but lower long-term survival. However, higher phenological sensitivity to spring warming was not strongly linked to increased productivity, and fitness was more closely linked to latitudinal gradients.

Summary: Northern Red Oak, a non-native deciduous tree species native to North America, has become the most common non-native deciduous tree species in Germany, covering over 350,000 hectares in Europe. This study analyzes the growth performance of Northern Red Oak in Germany, focusing on common provenances from North America and Germany. The results show that German provenances have a higher productivity on humid sites, while provenances from Canada perform well in dry environments. The study also assesses the provenance sensitivity across different environments and classifies the provenances into generalists and specialists, providing important insights for the broader use of Northern Red Oak in forest restoration in Germany.

Summary: Bark wounding induces limited embolism spreading. The impacts of bark wounding may not significantly limit water delivery to distal organs and leaf gas exchange.

Summary: Plant populations at the leading edge of the species' native range often exhibit genetic structure as a result of genetic drift and adaptation. This study examines the genetic structure of northern red oak populations, finding pronounced genetic differentiation between island and mainland/peninsular populations. Additionally, strong fine-scale spatial genetic structure is observed in all locations, with more pronounced structure in colder and drier regions. The study suggests that the harsh environment of leading edge populations influences population density and seed shadow overlapping, leading to the observed patterns of genetic structure.

Summary: The study found that photosynthesis undergoes complex changes throughout the season, with a peak in photosynthetic capacity and rate occurring towards the end of the season, correlated with higher summer temperatures and vapor pressure deficit. The simulated results of photosynthesis were closely associated with the maximum carboxylation capacity of Rubisco.

Summary: This study compared the growth and yield of northern red oak and native oak in southern Sweden, showing that red oak had slightly higher volume growth and larger diameter at the same stand age as native oak.

Summary: The use of biostimulants in modern agriculture has expanded rapidly in recent years due to their beneficial effects on crop yield and product quality. In this study, the efficacy of two plant-derived biostimulants on lettuce cultivars was evaluated, showing cultivar-dependent responses to biostimulant types. Biostimulants can potentially improve lettuce yield and quality by stimulating plant physiological processes and increasing the biosynthesis of various compounds.

Summary: The study investigated the physiological status of S. hermaphrodita plantations growing on two different marginal lands, one contaminated with heavy metals and one nutrient-poor sandy soil. Higher biomass yield was found on the heavy metal contaminated site, indicating that soil quality was the main factor affecting yield. S. hermaphrodita is a more suitable option for fertile but heavy metal polluted soils, but further research on biomass quality is needed.

Summary: Mining activities alter critical soil properties for plant establishment. Microbial inoculations can potentially improve vegetation restoration. This study evaluates the feasibility of using commercially available inoculants to enhance plant performance in a non-toxic and infertile mine-waste substrate, finding that water availability has a greater effect on plant growth than inoculation treatments.
