Denitrification dominates dissimilatory nitrate reduction across global natural ecosystems

Global Change Biology, Год журнала: 2024, Номер 30(3)

Abstract Denitrification, anaerobic ammonium oxidation (anammox), and dissimilatory nitrate reduction to (DNRA) are three competing processes of microbial that determine the degree ecosystem nitrogen (N) loss versus recycling. However, global patterns drivers relative contributions these N cycling soil or sediment remain unknown, limiting our understanding balance management. Here, we compiled a dataset 1570 observations from wide range terrestrial aquatic ecosystems. We found denitrification contributed up 66.1% total globally, being significantly greater in estuarine coastal Anammox DNRA could account for 12.7% 21.2% reduction, respectively. The contribution increased with longitude, while anammox decreased. local environmental factors controlling included concentrations organic carbon, ammonium, nitrate, ferrous iron. Our results underline dominant role over transformation, which is crucial improving current cycle model achieving sustainable

Porewater exchange drives the dissolved silicate export across the wetland‐estuarine continuum

Frontiers in Marine Science, Год журнала: 2023, Номер 10

Coastal wetlands are an important hotspot for nutrient cycling and transport from the land to ocean. Silicon (Si) as a vital biogenic element affects plant growth health of coastal ecosystems. The understanding key factors processes controlling dissolved silicate (DSi) exchange between water has been limited due lack measured data. We carried out intensive investigations time-series DSi concentrations porewater across Sediment-Water Interface (SWI) along tidal creek with mangrove-salt marsh gradient during neap spring tides in 2020. Seasonal observations surface Zhangjiang Estuary (Fujian Province, China) were conducted 2017 results showed that there was net export mangroves rates 2.11 2.40 mmol m -2 d -1 respectively, suggesting served source DSi. However, salt marshes had import one or two orders magnitude lower than mangroves. wetland‐estuarine continuum largely controlled by exchange, groundwater geochemistry (pH, temperature) root uptake.

This study provides new insights into wetland Si sustaining ecosystem health.

Soil Organic Nitrogen Mineralization and N₂O Production Driven by Changes in Coastal Wetlands

Global Biogeochemical Cycles, Год журнала: 2024, Номер 38(6)

Abstract Plant invasion and land reclamation have drastically transformed the landscape of coastal wetlands globally, but their resulting effects on soil organic nitrogen (SON) mineralization nitrous oxide (N 2 O) production remain unclear. In this study, we examined 21 across southern China that undergone habitat transformation from native mudflats (MFs) to Spartina alterniflora marshes (SAs), subsequently earthen aquaculture ponds (APs). We determined SON net rate presence pertinent enzyme‐encoding genes, namely chiA , pepA pepN . The increased by 46.7% following conversion MFs SAs decreased 33.1% in response APs. Nevertheless, there was no significant difference estimated efficiency microbes among types. results structural equation modeling showed N‐mineralization gene abundance played a major role regulating mineralization. Although less than 20% be labile/semi‐labile, important sustaining N O production, with 5.8% mineralized being fed into production. Overall, our findings S. both content rate, which would turn promote further proliferation exotic plant along coast. APs partially mitigated positive turnover.
