Summary: This study found that precipitation history has an impact on the microbial community's response to rewetting, which is related to the nitrogen status. Regardless of precipitation or nitrogen input history, active bacteria showed a small shift in community composition within 1 hour of rewetting, but did not change further for the remaining 28 hours analyzed. Active fungi did not respond to rewetting within 29 hours. These findings are important for understanding the short-term response of soil microbial communities and their effects on food web stability and soil biogeochemical cycling.

Summary: Overexploitation of natural forest resources in the tropical semiarid region of Brazil leads to soil degradation, reduction in microbial and plant biomass, and loss of C and N from soils. This study found that degraded soils had significantly lower C and N stocks, abundance and activity of total bacteria and fungi, and decreased abundance of diazotrophic and phosphorus-mineralizing bacteria compared to preserved or partially degraded soils. However, the abundance of total bacteria and fungi genes and glomalin content remained unchanged. The alkaline phosphatase activity indicated that mineralizing microorganisms can still make phosphorus constantly available in soils without vegetation cover.

Summary: This study found that the microbial biofilm communities near mariculture areas can affect the settlement of coral larvae. The biofilm farthest from the mariculture area had a higher effectiveness in inducing the settlement of Acropora tenuis larvae. These biofilms were characterized by a greater proportion of crustose coralline algae and gammaproteobacterial taxa, while biofilms closer to the mariculture zone had a higher proportion of cyanobacteria and no crustose coralline algae. These findings suggest that nutrient enrichment from mariculture activities can alter the composition of biofilm-associated microbiome and indirectly affect coral larval settlement.

Summary: Microbes play a critical role in plant litter decomposition and the fate of carbon in rivers and riparian zones. The process of nutrient immobilization, whereby microbes acquire nitrogen and phosphorus from the environment during the decomposition of low-nutrient plant litter, is influenced by nutrient loading and changing climate. However, environmental controls on immobilization are poorly understood due to the complex interplay between environmental factors and plant litter chemistry.

Summary: This study investigates the microbial interactions in organic matter decomposition (OMD) and the influence of environmental factors on microbial interactions in river ecosystems. The researchers use cotton strip as a substitute for organic matter in the Luanhe River Basin in China. The results show that bacteria and fungi cooperatively form an interaction network to achieve the decomposition of cotton strip. The key modules in the network, mainly composed of Proteobacteria and Ascomycota, are identified as the effective decomposers. Water temperature and total nitrogen are dominant environmental factors positively influencing the decomposition process.

Summary: The increasing production, use and emission of synthetic chemicals into the environment is a major driver of global change. Recent advances in biomolecular and computational methods show promise for improving our capacity to predict the effects of these chemicals. However, the complexity of the chemicals, limited knowledge on exposure patterns and effects, and the lack of data covering different levels of biological organization pose challenges to prediction.

Summary: Trait-based approaches are increasingly used in ecology to understand the influence of individual-level trait variation on communities and species. This study examined the responses of individual trait variation of the diatom genus Aulacoseira to environmental changes in the Pearl River Delta. The results showed that different factors regulated the trait richness, trait evenness, and trait dispersion of Aulacoseira, with abiotic factors having a stronger direct influence than biotic factors. This study highlights the potential of multidimensional trait variation as an effective indicator for tracking environmental changes.

Summary: Changes in land use and land cover significantly influence river water quality. This study utilized spatial data from 39 catchments in the southern basin of the Caspian Sea to investigate the impact of landscape structure on water quality. The findings reveal that landscape structure metrics, particularly the shape index, contiguity index, and fractal metric, can predict variations in total dissolved solids (TDS) and magnesium (Mg) concentrations. Optimizing landscape structure metrics in land use planning can help reduce river pollution and improve water quality.

Summary: Biodiversity loss caused by human activities poses a threat to human well-being, but the combined effects of multiple stressors on community diversity, both alpha and beta, are not well understood. A long-term experiment on the Songhua River in China from 2012 to 2019 revealed a decline in alpha and beta diversity indices, particularly in impacted river sections. Despite improved water quality, human-caused stressors have led to biotic homogenization of macroinvertebrate communities, with land use being a significant factor. Different facets of diversity have distinct response mechanisms to stressors, providing complementary information in assessing ecological changes. This study highlights the importance of long-term monitoring and the need for timely control of nutrient input and land use expansion to protect river ecosystems.
