Summary: Salinity is a detrimental stress for crop productivity, but can be overcome by growing high value tree species on saline lands. This study evaluated the effect of saline irrigation and different host species on the growth, physiological processes, and salinity tolerance of sandalwood. Results showed that sandalwood grown with Dalbergia sissoo, Azadirachta indica, and Melia dubia exhibited higher growth and tolerance under salinity stress. The growth parameters of sandalwood were negatively correlated with Na+ ion under salinity stress. Hosts Melia dubia, Dalbergia sissoo, and Azadirachta indica showed minimal decline in sandalwood growth and biomass under salinity stress. This study highlights the importance of host species in modulating sandalwood growth and its potential for cultivation in degraded saline soils.

Summary: Batillaridae is a common gastropod family found in the shallow coastal zone of the Pacific Ocean, Australasia, and North America. Batillaria attramentaria, a member of this family, is known for its ability to invade and colonize estuarine and intertidal zones. Through genome sequencing and analysis, we gained insights into its adaptive features in intertidal environments.

Summary: This paper reviews the research progress of using organic carbon sources for mixotrophic and heterotrophic cultivation in diatoms from an aquaculture perspective, aiming to improve diatom growth rate, biomass, and metabolites. The impact of fermented feed on diatom culture is discussed for the first time, guiding the development of a more efficient and practical nutrient supplement.

Summary: Salt stress significantly decreases yield and quality in wheat. This study investigated the physiological, antioxidant enzyme, and transcriptomic responses and mechanisms of salt-tolerant Tritipyrum (Y1805) and salt-sensitive wheat Chinese Spring (CS) to salt stress and recovery. Y1805 exhibited stronger salt tolerance, higher activities of superoxide dismutase and catalase, and higher synthesis of proline and soluble sugars compared to CS under salt stress. Transcriptome analysis revealed differences in the transcriptional regulatory networks of Y1805 not only in response to salt stress, but also during recovery.

Summary: This study demonstrates the use of mollusc shells as high-resolution sea-surface temperature proxies in wave-dominated rocky intertidal ecosystems. Through analyzing oxygen isotope signatures of an endemic Hawaiian limpet, the research provides insights into tropical intertidal climatology and the life-history of molluscs in this unique environment.

Summary: Increasing Arctic temperatures have led to accelerated melting of the Greenland ice sheet, exposing intertidal organisms like Mytilus edulis to high air temperatures and low salinities in the summer. This study found that the combined stressors of high temperature and low salinity push M. edulis towards their tolerance thresholds, leading to an increase in upregulated genes. The organism also exhibits efficient mechanisms, such as intracellular osmoregulation and fluid-filled cavities, to acclimatize to changing salinity levels. These findings demonstrate the resilience of M. edulis to heat stress and lowered salinity in a changing world.

Summary: This work reveals the degradation in properties and molecular mechanisms of colorless transparent polyimide (CPI) films with different functional groups under photo-oxidation. It is found that the mechanical properties and thermal stability of CPI films are decreased, and the yellowness index is increased significantly after photo-oxidation. The molecular mechanisms involved in the degradation process are proposed, and the enrichment of C-O on the surface of CPI films is observed.

Summary: Plants in nature often encounter combined stress scenarios, and their response to such stresses can be unpredictable. This study investigated the metabolomic acclimation of sugar beet roots under the combined stress of salinity, heat, and high light. The results showed that high salt and high temperature significantly decreased the amounts of certain metabolites, while the combination of high light and high salt led to a decline in specific metabolite contents. These findings highlight the complex interaction patterns of environmental factors and emphasize the importance of studying combinatorial stress effects.

Summary: This study compared four different bio-environmental datasets to explore the complex marine ecosystem of the Baffin Bay-Labrador Sea region and the historical links between environmental changes and the ecosystem. The research revealed significant correlations between different trophic levels, culminating in a 'productivity boom' in 2001.

Summary: This study tested the ability of Nepeta cataria L. to grow and synthesize bioactive compounds in soil with different salt concentrations. The results showed that high salinity stress inhibited plant growth, but increased the density of granular trichomes as a defense mechanism. The chlorophyll content varied with salt concentration, while antioxidant activity played a protective role against salinity stress.

Summary: Implementing large-scale restoration programs in salt-affected areas requires understanding the salinity tolerance of native species. This study assessed the survival, growth performance, biomass, and proline accumulation of four native species under different salinity treatments. The results showed species-specific responses to salinity stress, with some species exhibiting higher tolerance than others. The data generated from this study will be valuable for selecting suitable plant species for restoration in salt-affected areas.

Summary: The study found that constructing small shellfish reefs in intertidal areas can alter the composition of diatom communities in biofilms, promoting the growth of smaller cells and species. These small diatoms have higher growth and photosynthesis rates, which explain the higher production and chlorophyll-a concentration in biofilms on natural intertidal shellfish reefs. The results indicate that shellfish reefs play a significant role in biofilm functioning.

Summary: The study analyzed the relationship between diatom assemblages and environmental variables in lakes across the Tibetan Plateau. A diatom-inference model for salinity was developed based on the findings. The study highlights the potential of using diatom reconstructions and changes in diatom community composition to track long-term climate and environmental patterns in the highly complex landscape of the Tibetan Plateau.

Summary: This study investigated the potential of halophytic endophytes from crop wild relatives to improve crop adaptations to various stresses, including salinity tolerance, growth promotion, and phytopathogen antagonistic activities. The researchers identified 115 endophytic isolates, three of which showed in-planta suppression of the phytopathogen Verticillium growth. Genomes of selected isolates were sequenced and three novel species were identified, suggesting the potential use of these endophytes as bio-inoculants for enhancing crop growth and stress tolerance, particularly in high-salinity conditions.

Summary: This study compared environmental conditions and phytoplankton biomass/composition in three Texas estuaries with different freshwater inflow regimes to understand the impact of freshwater inflow on phytoplankton communities. The results showed that despite differences in freshwater inflow, salinity, and nutrient regimes, differences in phytoplankton community composition were relatively small, indicating the influence of other factors.
