However, the effects of increased nitrogen (N) availability on DOM dynamics and the underlying mechanisms remain unclear in northern peatlands. We conducted a 14-year N addition experiment (0, 3, 6, and 12 g N·m^-2·a^-1) in a peatland located in the continuous permafrost region of the northern Greater Khingan Mountains. We examined the effects of N addition on DOM chemical composition and biodegradability in surface water and soil pore water (0-15 cm) using the excitation-emission matrix (EEM) fluorescence spectroscopy and laboratory incubation experiments. We found that dissolved organic carbon (DOC) and dissolved total nitrogen (DTN) concentrations in surface water initially increased and then decreased with the increases of N addition levels. Compared with control, N addition at 6 g N·m^-2·a^-1 had 44.8% and 944.5% higher DOC and DTN concentrations, respectively. In contrast, dissolved total phosphorus (DTP) decreased from 0.20 mg·L^-1 to 0.08 mg·L^-1 with increasing N addition levels. These changes resulted in the increases in the DOC:DTP and DTN:DTP ratios, showing the shift in the nutrient limitation status from N to P. Fluorescence analysis revealed that N addition increased the proportion of relatively labile components such as protein-like components, but reduced the proportion of humic-like components. A 42-day incubation experiment showed that DOM biodegradability initially increased and then decreased with increasing N addition levels. In surface water, N addition at 6 g N·m^-2·a^-1 had the highest DOM biodegradability (30.3%), while in soil pore water, N addition at 3 g N·m^-2·a^-1 had the greatest DOM biodegradability (28.8%). Furthermore, the stepwise regression analyses showed that DOM biodegradability correlated significantly with C quality and nutrient availability in surface water, but correlated significantly with the intrinsic aromaticity in soil porewater. Overall, our findings demonstrated that N enrichment could alter DOM chemical composition and biodegradability in northern peatlands, with implications for understanding C cycling in these ecosystems.</p>","PeriodicalId":35942,"journal":{"name":"应用生态学报","volume":"37 9","pages":"3151-3158"},"PeriodicalIF":0.0,"publicationDate":"2026-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149165328","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Previous studies primarily focus on vertical carbon sequestration in carbon sink assessments, often overlooking the key pathway of lateral carbon exchange. We systematically reviewed the biogeochemical transformation processes, key measurement methods, and driving mechanisms of key components in lateral carbon exchange (dissolved inorganic carbon, dissolved organic carbon, and particulate organic carbon) in coastal wetlands. Compared to vertical carbon burial rates, lateral carbon export rates in coastal wetlands are higher, with no differences among different types of coastal wetlands. The key processes include porewater exchange driven by tidal pumping and submarine groundwater discharge (SGD). Tidal processes drive periodic porewater exchange between sediments and overlying water bodies, promoting the release of dissolved substances from sediments. Meanwhile, multiple geophysical processes, including hydraulic gradients, tidal-induced seabed pressure variations, wave action, and density differences between seawater and groundwater collectively govern the occurrence and intensity of SGD. In terms of driving mechanisms, the tidal pumping effect, porewater exchange, and SGD are the core drivers of lateral carbon export, while extreme weather events (<i>e.g</i>., typhoons, heavy rainfall) dominate short-term carbon flux variations through triggering effects and hydrodynamic intensification. Carbon exported laterally to offshore areas achieves long-term sequestration via pathways such as the carbonate system buffering and sedimentation into deep-sea sediments, yet remains strongly perturbed by human activities and climate change.

Recently, studies have achieved critical transitions from macroscopic factors to microscopic mechanisms, and from single interfaces to multi-interface coupling. We examined the cascading feedback theories of seasonal rainfall variation on soil organic carbon dynamics in estuarine wetlands. The academic community has gradually clarified its core evolutionary pathways. At the carbon input end, drying-rewetting pulses drive the spatiotemporal decoupling of above- and below-ground primary productivity, reshaping the carbon supply pattern. At the carbon emission end, moisture fluctuations prompt shifts in resource acquisition strategies of plants to regulate autotrophic respiration and reorganize microbial niches to trigger pulsed greenhouse gas releases. Regarding fractions and chemical structure, drying-rewetting cycles accelerate the phase transformation between labile and stable carbon and the selective enrichment of micro-molecules. Finally, from the perspective of sources and stability, the deterioration of physicochemical stabilization mechanisms, such as microaggregate breakdown and the failure of iron-carbon complexation, acts as the core pivot triggering fundamental carbon source-sink transitions. Although the theoretical outline has emerged, there are significant deficiencies in quantitative analysis and mechanistic coupling of multi-interface ecological processes. Future research should focus on: identifying the critical drought thresholds that trigger carbon source-sink abrupt shifts, unraveling the response mechanisms of deep carbon dynamics to plant carbon allocation decoupling, exploring the ecological buffering roles of multi-trophic interaction networks in maintaining carbon stability, and developing process-based predictive models coupling fine carbon fractions with multiple stabilization mechanisms.</p>","PeriodicalId":35942,"journal":{"name":"应用生态学报","volume":"37 9","pages":"3019-3027"},"PeriodicalIF":0.0,"publicationDate":"2026-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149169606","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Wetland vegetation can alter the source-sink status of P at this interface by modifying hydrodynamic conditions, rhizosphere redox environments, plant uptake, and microbial processes. We synthesized the mechanisms by which wetland vegetation regulates P transport and transformation across the sediment-water interface, including physical sediment stabilization, radial oxygen loss, and iron-phosphorus coupling, plant-microbe interactions, and litter decomposition feedbacks. We further compared the regulatory effects of different plant life forms and community characteristics. Emergent plants generally exhibit strong rhizosphere oxygenation and sediment-stabilizing capacities, thereby favoring P retention at the interface. Submerged plants can reduce P release by increasing near-bottom dissolved oxygen, taking up P, and suppressing sediment resuspension. By contrast, the long-term effects of floating-leaved and free-floating plants depend more strongly on vegetation coverage, litter management, and bottom-water oxygen conditions. The effectiveness of vegetation-mediated P regulation is jointly constrained by hydrological fluctuations and wetting-drying cycles, temperature, dissolved oxygen, pH, sediment properties, initial P speciation, and external P loading. During the growing season, plant P uptake and interfacial P retention generally predominate, whereas senescence or disturbance may increase P release risks through litter return, oxygen depletion, and weakened sediment stabilization. Consequently, the long-term effect of wetland vegetation on P cycling is strongly context dependent. Future research should focus on identifying thresholds under multiple interacting factors, elucidating functional plant-microbe interactions, developing high-resolution <i>in situ</i> monitoring approaches, and evaluating the long-term stability of P source-sink dynamics, thereby providing a scientific basis for wetland vegetation restoration and precise management of internal P loading.</p>","PeriodicalId":35942,"journal":{"name":"应用生态学报","volume":"37 9","pages":"2945-2962"},"PeriodicalIF":0.0,"publicationDate":"2026-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149170172","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, a systematic understanding of such effect remains insufficient. We systematically reviewed the effects of wetland vegetation changes on land surface temperature from three perspectives: distribution patterns, vegetation coverage, and phenological dynamics. The regulation of key biophysical processes such as evapotranspiration, surface albedo, and turbulent exchange by wetland vegetation changes exhibits pronounced spatiotemporal heterogeneity, thereby leading to divergent surface energy partitioning and temperature feedbacks. Changes in vegetation distribution patterns can alter surface roughness and evaporation potential, thereby modifying the spatial configuration of turbulent exchange and water-heat fluxes, with consequences on land surface temperature. Increases in vegetation coverage drive daytime cooling by enhancing evapotranspiration, but this effect displays marked spatial variability. For example, it is more pronounced in semi-arid regions than in humid ones, and reverses to a warming effect during winter at high latitudes. Seasonal variations in the physiological activity of wetland vegetation can regulate the intensity of water vapor exchange, alter the temporal allocation of surface energy, and thus drive seasonal fluctuations in land surface temperature. There are some limitations of current research: inadequate differentiation and mechanistic quantification of the coupled interactions between wetland vegetation dynamics and hydrological processes, and insufficient process-based attribution of energy balance components, particularly latent, sensible and ground heat fluxes. The improved parameterization and ground validation of models that simulate wetland vegetation-hydrology-energy exchange processes are critically needed. In the future, it is necessary to integrate multi-source data and models, quantitatively separate the contributions of radiative and non-radiative processes, and couple biogeochemical processes to construct a unified framework for assessing climate effects, which will provide theoretical support for wetland conservation and restoration and accurate prediction of wetland climate-regulation functions under the background of global change.</p>","PeriodicalId":35942,"journal":{"name":"应用生态学报","volume":"37 9","pages":"2897-2907"},"PeriodicalIF":0.0,"publicationDate":"2026-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149165345","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
