Abstract Mangrove ecosystems are highly productive, sequestering large amounts of carbon from the atmosphere while emitting relatively low levels greenhouse gases. Large organic matter and nitrogen river discharge may stimulate production emission gases including N2O, thus reducing blue storage capacity mangrove wetlands. However, it is unclear how input affect fluxes these in In this study, we compared effluxes N2O between estuarine non-estuarine wetlands near seven major rivers on Hainan...
Peatlands cover only 3% of Earth’s land surface but contain about 30% the global soil carbon pool. Derived predominantly from plant litter and moss accretions, peat deposits are critically sensitive to environmental dynamics such as temperature moisture levels. This vulnerability has raised concerns potential positive feedback mechanisms in relation climate change. However, current models present disparities projected emissions, sensitivities peatland stocks changing environments a...
Ericaceous shrubs adapt to the nutrient-poor conditions in ombrotrophic peatlands by forming symbiotic associations with ericoid mycorrhizal (ERM) fungi. Increased nutrient availability may diminish role of ERM pathways shrub uptake, consequently altering biogeochemical cycling within bogs. To explore significance fungi peatlands, we developed model MWMmic (a peat cohort-based model) into MWMmic-NP explicitly incorporating plant-soil nitrogen (N) and phosphorus (P) processes. The new was...
The effects of acid deposition on pine forest ecosystems in Longli Guizhou Province, southwestern China are studied using indoor experiments and model simulations. Indoor designed to explore the aluminum toxicity seedlings, long-term soil acidification (LTSAM) a terrestrial biogeochemistry (CENTURY) used simulate influences ecosystems. experiment results show that ions solution limit plant growth enhances this effect by facilitating release from soil. Pine seedling biomass root elongation...
Peatlands cover only 3% of Earth’s land surface but contain about 30% the global soil carbon pool. The strong sensitivity C cycle to environmental factors such as temperature and moisture has let concerns potential positive feedbacks climate change. However, models disagree magnitude spatial distribution emissions, partially due missing representations peatland relevant processes a scarcity in situ observations. Spruce Peatland Responses Under Changing Environments (SPRUCE)...
<p>Northern peatlands have sequestered a huge amount of carbon through exceptionally low microbial activity which is partly attributed to their nutrient-poor conditions. Evergreen shrubs, dominant species in ombrotrophic bogs, adapt this condition by developing organic nutrient acquisition strategies, mediated ericoid mycorrhizal association. However, the symbionts together with cycling been omitted peatland models, precluding our ability simulate significance limitation...
