Coastal wetlands capture carbon dioxide from the atmosphere at high rates and store large amounts of “blue carbon” in soils. These habitats are home to a variety microbial communities that break down organic matter cycle nutrients, playing substantial role coastal biogeochemical balance. Rising sea levels make more susceptible saltwater intrusion, which might disrupt processes, such as sulfur methane generation/consumption by bacteria thus disrupting existing equilibria. A change equilibria may produce important climate-related feedback because these systems, while involved sequestration, also have potential emit greenhouse gases, with reported higher emissions freshwater ecosystems compared brackish ones. In this study, we characterize community geochemical properties soils three temperate along salinity gradient assess effect on decomposition related gas emissions.

Summary Climate and edaphic properties drive the biogeographic distribution of dominant soil microbial phylotypes in terrestrial ecosystems. However, impact plant species their root nutritional traits on coastal wetlands remains unclear. Here, we investigated 100 halophyte samples bacterial communities corresponding from across eastern China. This study spans 22° latitude, covering over 2500 km north to south. We found that 1% accounted for nearly 30% community abundance, suggesting a few dominated wetlands. These could be grouped into three ecological clusters as per preference climatic (temperature precipitation), (soil carbon nitrogen), factors (halophyte vegetation, carbon, nitrogen). further provide novel evidence traits, especially C N, can strongly influence these clusters. Taken together, our provides solid revealing dominance specific complex interactions with environment, highlighting importance microbiome wetland

The soil microbial community plays a crucial role in the elemental cycling and energy flow within wetland ecosystems. temporal dynamics spatial distribution of communities are central topics ecology. While numerous studies have focused on structures at low altitudes, diversity across seasons depths their environmental determinants remain poorly understudied. To test seasonal variation with contrasting fluxes greenhouse gases, total 36 samples were collected from different Namco Tibetan Plateau four seasons. We found significant bacterial composition, most pronounced Winter, but not archaea. In particular, Proteobacteria decreased by 11.5% Winter compared other (p < 0.05). alpha showed hump-shaped patterns lower whereas archaea no depths. A PERMANOVA further revealed differences structure between three addition, archaeal differed surface (0–5 cm) deeper (5–30 soils 0.01).

Soil microbes play a vital role in tidal flat ecosystems but are highly susceptible to disturbances from land reclamation. This study investigated the dynamics of bacterial communities and their environmental drivers across 50-year reclamation chronosequence under three vegetation types (bare flats, reed beds, rice fields). The results showed that, after 50 years reclamation, total dissolved salts decreased significantly vegetated zones, particularly fields, where Cl− dropped by 54.71% nutrients (SOC, TN, TP) increased substantially. Key ions, including HCO3−, Cl−, K+, were primary microbial community structure, exerting more influence than salinity (TDS) or pH. Bacterial abundance diversity over time, with fields showing highest values years. Actinobacteriota Proteobacteria positively correlated HCO3− while negatively affected Acidobacteriota. Genus-level analyses revealed that specific taxa, such as Sphingomonas Gaiella, exhibited ion responses diverging broader phylum-level patterns, exemplifying niche-specific adaptations regimes. These findings underscore pivotal type individual ions driving succession during A phased strategy, starting colonization followed cultivation, can enhance soil quality diversity. research provides important insights for optimizing management monitoring sustainable

Soil bacteria are crucial components of terrestrial ecosystems, playing an important role in soil biogeochemical cycles. Although bacterial community diversity and composition regulated by many abiotic biotic factors, how physiochemical properties impact the wetland ecosystems remains largely unknown. In this study, we used high-throughput sequencing technology to investigate a community, as well structural equation modeling (SEM) method relationships soil's physicochemical (i.e., pH, organic carbon (SOC), total nitrogen (TN), ammonium (NH4+N), electrical conductivity (EC) nitrate (NO3-N)), structures three typical sites Sanjiang Plain wetland. Our results showed that significantly changed α β-diversity communities, e.g., TN, NH4+N, NO3-N, SOC were main factors affecting α-diversity. The TN pH key community. suggest changes indirectly affect communities altering nitrogenous nutrient content.

In situ contaminant degradation and detoxification mediated by microbes minerals is an important element of green remediation. Improved understanding microbe-mineral interactions on the nanoscale offers promising opportunities to further minimize environmental energy footprints site this Perspective, we describe new methodologies that take advantage array multidisciplinary tools─including multiomics-based analysis, bioinformatics, machine learning, gene editing, real-time spectroscopic microscopic computational simulations─to identify key microbial drivers in real environments, characterize dynamic interplay between with high spatiotemporal resolutions. We then reflect how knowledge gained can be exploited modulate binding, electron transfer, metabolic activities at interfaces, develop detoxication technologies combined merits efficacy, material longevity, low impacts. Two main strategies are proposed maximize synergy microbes, including using mineral nanoparticles enhance versatility microorganisms (e.g., tolerance stresses, growth metabolism, directed migration, selectivity, transfer), synthesize regenerate highly dispersed nanostructures desired structural/surface properties reactivity.
