Abstract Wetlands are the largest natural source of methane (CH 4 ) globally. Climate and land use change expected to alter CH emissions but current future wetland budgets remain uncertain. One important predictor flux, plants, play an role in providing substrates for ‐producing microbes, increasing consumption by oxygenating rhizosphere, transporting from soils atmosphere. Yet, there various mechanistic knowledge gaps regarding extent which plant root systems their traits influence emissions. Here, we present a novel conceptual framework relationships between range processes wetlands. Based on literature review, propose four main ‐relevant categories function: gas transport, carbon substrate provision, physicochemical influences system architecture. Within these categories, discuss how individual production, consumption, transport (PCT). Our findings reveal concerning trait functions influences, mycorrhizae temporal dynamics PCT. We also identify priority research needs such as integrating measurements different function measuring root‐CH linkages along environmental gradients, following standardized ecology protocols vocabularies. Thus, our identifies relevant belowground that will help improve predictions reduce uncertainties budgets.

Abstract The Legal Amazon of Brazil holds vast mangrove forests, but a lack awareness their value has prevented inclusion into results-based payments established by the United Nations Framework Convention on Climate Change. Based an inventory from over 190 forest plots in mangroves, we estimate total ecosystem carbon stocks 468 ± 67 Megagrams (Mg) ha −1 ; which are significantly higher than Brazilian upland biomes currently included national offset financing. Conversion mangroves results potential emissions 1228 Mg CO 2 e , 3-fold land use conversion rainforest. Our work provides foundation for Brazil’s intended Nationally Determined Contribution, and here show that halting deforestation would generate avoided 0.9 0.3 Teragrams (Tg) yr is equivalent to annual accumulation 82,400 secondary forests.

Abstract Agriculture is one of the major sources global emissions that cause climate change while agricultural value added helps to boost economy in developing countries like China. Therefore, this study aims investigate long- and short-term influences added, economic growth (GDP), energy use on carbon dioxide (CO 2 ) The autoregressive distributed lag (ARDL) method was used by using annual time series data from 1990 2021. empirical outcomes revealed a 1% increase would cut CO 1.37% long-run 0.65% short-run.

Abstract Redox processes, aqueous and solid‐phase chemistry, pH dynamics are key drivers of subsurface biogeochemical cycling methanogenesis in terrestrial wetland ecosystems but typically not included carbon cycle models. These omissions may introduce errors when simulating systems where redox interactions fluctuations important, such as wetlands saturation soils can produce anoxic conditions coastal sulfate inputs from seawater influence biogeochemistry. Integrating redox‐sensitive elements could therefore allow models to better represent greenhouse gas production. We describe a model framework that couples the Energy Exascale Earth System Model (E3SM) Land (ELM) with PFLOTRAN biogeochemistry, allowing geochemical processes be integrated land surface simulations. implemented reaction network including aerobic decomposition, fermentation, reduction, sulfide oxidation, methanogenesis, methanotrophy well along iron oxide mineral precipitation dissolution. simulated tidal subject either saltwater or freshwater driven by hydrological dynamics.

Abstract Sinuous channel networks dissecting tidal wetlands are highly dynamic and often abandoned as a result of captures meander cutoffs. However, the effects dynamics on blue carbon fluxes remain unclear. Analyses channels in Venice Lagoon (Italy) demonstrate that they take up organic at significantly faster rates than neighboring marshes. This is because, despite slightly lower sediment density, yield higher vertical accretion owing to topographic accommodation reduced flow velocities, which facilitate deposition particulate matter debris. We estimate capture 17 tons annually, equivalent 21 ha marshes, covering only 3.5 total. Hence we argue serve hotspots for blue‐carbon accumulation should be considered improve estimates coastal wetlands.

Anaerobic methane oxidation (AMO) is a key microbial pathway that mitigates emissions in coastal wetlands, but the response of AMO to changing global climate remains poorly understood. Here, we assessed change brackish wetland using 5-year field manipulation warming and elevated carbon dioxide ( e CO 2 ). Sulfate (SO 4 2− )–dependent (S-DAMO) was predominant process at our study site due tidal inputs SO . However, dynamics responded differently treatments; reduced concentration by enhancing reduction, while increased regeneration. S-DAMO rates mirrored these trends, with decreasing stimulating them. These findings underscore potential alter soil activities through dynamics, highlighting need incorporate processes predictive models for more accurate representations dynamics.
