Abstract In the global ecosystem, wetlands are vital carbon sinks, playing a crucial role in absorbing greenhouse gases such as dioxide and mitigating warming. Accurate estimation of wetland content is essential for research on sinks. However, cycle complex, sinking affected by climate, topography, water level conditions, vegetation types, soil other factors. This has caused significant challenges current studies, most focused impact individual factors often ignoring interaction between various factors, which further leads to uncertainty measurements. paper aims elucidate process cycle, summarize affecting explore interplay their influence aiming provide theoretical support study Additionally, this reviews advantages disadvantages measurement methods, proposes directions combining machine learning identifies existing difficulties measurement, offers suggestions serve reference future sink management.

ABSTRACT Microorganisms are a crucial component of lake ecosystems and significant contributors to biogeochemical cycles. However, the understanding how primary microorganism groups (e.g., bacteria fungi) distributed constructed within different habitats is lacking. We investigated bacterial fungal communities Hulun Lake using high-throughput sequencing techniques targeting 16S rRNA Internal Transcribed Spacer 2 genes, including range ecological statistical methodologies. Our findings reveal that environmental factors have high spatial temporal variability. The composition community structures vary significantly depending on differences in habitats. Variance partitioning analysis showed geographical accounted for <20% variation. Canonical correlation among factors, temperature, pH, dissolved oxygen had strong control over microbial communities. (bacterial fungal) were primarily controlled by dispersal limitations stochastic processes. This study offers fresh perspectives regarding maintenance mechanism biodiversity ecosystems, especially responses under identical stress. IMPORTANCE an important part freshwater ecosystem. microorganisms play role material circulation energy flow owing their unique enzymatic metabolic capacity. In this study, we observed varied widely water sediments Lake. factor affecting formation was identified as limitation during Environmental variation communities, with being factors. provide new insights into fungi environment, shed light processes building, deepen our ecosystems. results reference management conservation, particularly respect monitoring response changes.

Plants could affect wetland ecosystem functions by influencing the carbon and nitrogen cycles driven microorganisms. However, underlying mechanisms associated with CO2-fixation rate (CFR) autotrophic microbes denitrification (DR) in relation to emergent plants remain unclear. In this study, we conducted a field experiment analyze effects of on activities community characteristics CO2-fixing bacteria denitrifying two types wetlands lake basin: freshwater brackish water. We found that CFR DR differed between wetlands. Compared wetland, exhibited higher rhizosphere, probably due abundance organic conducive facultative bacteria. lower rhizosphere compared was salt stress. both wetlands, soil increased DR. The microbial communities them were distinct from those non-rhizosphere. Besides, neutral-based processes governed assembly these bacterial communities, while showed more prominent dominance niche-based than Statistical analyses revealed root exudates jointly drove differences metabolic composition CO2-fixation- denitrification-associated Overall, our findings suggest released through plant litter is vital for promoting carbon-fixation alleviating detrimental salinity denitrification.

The soil carbon storage in the Qinghai–Tibet Plateau wetlands is affected by microbiota and wetland types, but response mechanisms of sequestration microorganisms on to different types are still poorly described. To explore differences microbial communities main influencing factors, this study took a marsh wetland, river source lakeside Qinghai Lake as research objects used high-throughput sequencing functional gene, cbbL, microorganisms. results showed that dominant bacterial group was Proteobacteria, Cyanobacteria. alpha diversity, relative abundance Proteobacteria total content were highest followed they lowest wetland. In addition, physical chemical characteristics three significantly different, temperature moisture most important factors affecting community structures carbon-sequestering There little difference nitrogen contents between However, also an factor diversity community. summary, type affects process sequestration.

Till present, natural wetlands have been continuously subjected to intensive pollution stress in recent years, mainly because of the rapidly growing industrialization and urbanization that are associated with a myriad anthropogenic activities land use practices. These man-made sources change chemical properties wetlands, which turn alter their microbial ecological biodiversity functions.

With the intensification of global warming, wetland greenhouse gas (GHG) emissions have attracted worldwide attention. However, scientific understanding GHGs is still limited. To gain a comprehensive and systematic current research status development trends in GHGs. We selected 1627 papers related to GHG from Web Science Core Collection database used bibliometric visualization analysis method reveal annual publication, main core forces, hotspots, this field. The results showed that field shows steady upward trend. United States institutions scholars play key role on "climate change" based three major (carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O)) has been continuously gaining popularity. In recent years, "water" become an emerging topic. More more studies focused enhancing pollutant treatment capacity, improving ecosystem productivity, maintaining water level stability, strengthening blue carbon sink function, exploring remote sensing applications wetlands, promoting restoration reduce emissions. Furthermore, we discussed influencing factors emission CO2, CH4, N2O wetlands summarized potential methods findings provide guidance reference sustainable reduction.

The ecological conservation red line (ECRL) framework plays an increasingly important role in biodiversity practices China. Following the implementation of ECRL, it is essential to systematically assess effectiveness this national policy mitigating negative impacts human disturbances on habitat quality at landscape and regional levels. Combined with remote sensing ground survey data, Integrated Valuation Ecosystem Services Trade-off (InVEST) model was used evaluate impact six major anthropogenic activities, built-up land, roads, mining crop water pollution, grazing, degradation two grassland river corridors (Kherlen River corridor Wuerxun corridor) Northeastern Then, different management scenarios assessed based ECRL framework. Our findings indicated that over 80% attributed grazing followed by pollution. Built-up land played minor roles causing degradation. Comparing scenario no scenario, Kherlen reduced 17.86%, improved 11.11%. Similarly, corridor, compared priority 69.23%, 2.38% scenario. Moreover, optimized including prohibition, enclosure, restoration habitats, further both corridors, resulting a 12.70% improvement for 3.57% corridor. work provides quantitative optimizing measures ECRL.
