Intensive mariculture activities result in eutrophication and enhance coastal deoxygenation. Deoxygenation profoundly influences nitrate reduction processes further the fate of nitrogen (N) systems. Herein, 15N isotope labeling, real-time PCR, high-throughput sequencing techniques were jointly used to investigate participation seasonal dynamics sediment pathways succession functional microbial communities during development deoxygenation a aquaculture zone. Denitrification dominated benthic (46.26-80.91%). Both denitrification dissimilatory ammonium significantly enhanced by summer (dissolved oxygen levels fell 2.94 ± 0.28 mg L-1), while anammox remained unchanged. The abundance nitrous oxide reductase gene nosZ increased community was sensitive deoxygenation, with Azospirillum Ruegeria accounting for majority. Pelobacter overwhelming nrfA (encoding nitrite reductase) community, which less affected variations driven bottom water combined temperature, chlorophyll a, abundances compositions. Our results implicated that oxygen-deficient zones could be substantial N sinks ecosystems important balance. Effective management measures need developed avoid exacerbation maintain sustainable mariculture.

Exotic Spartina alterniflora invasion enhances sediment N-loss while reducing N retention in mangrove wetland

Wide and rapid Spartina alterniflora invasion has threatened the sustainability of coastal wetlands China, a significant impact on sediment biogeochemical cycle. However, effects exotic dissimilatory nitrates (NOx−) reduction processes mechanisms underlying these pathways in mangrove have not been well studied. Here, denitrification (DEN), anaerobic ammonium oxidation (ANA) nitrate to (DNRA) rates, contributions (DEN%, ANA%, DNRA%), associated functional genes (nirS, anammox 16S rRNA nrfA) controlling factors were investigated surface sediments (0–5 cm) communities ecotone Zhangjiang Estuary, China. Significant spatial differences DEN, DNRA, DEN%, DNRA% found among different plant (p < 0.05 for all). DEN is dominant pathway NOx− community (87–89 %) (75–78 %), while (41–51 DNRA (36–51 compete with each other community. Organic matter was most dominating factor rates. Without accounting confounding factors, significantly reduced nitrogen retention index (NIRI), causing large amount (N) loss wetlands. We estimated that increased N-loss (831.09 ± 55.16 t N yr−1) but (783.48 37.73 habitats China within last 40 years (1980–2020). Thus, enhances reducing wetlands, which may threaten buffer function wetland pools protection estuarine ecosystems.

Responses of microbial communities and greenhouse gas production to land use change in mangrove wetland sediments

Limnology and Oceanography, Год журнала: 2025, Номер unknown

Опубликована: Март 13, 2025

Abstract Tidal wetland reclamation is a worldwide issue that profoundly alters ecological functions and ecosystem service provisions; however, its impacts on sediment microbial communities remain poorly understood. Here, we investigated the spatial seasonal patterns of greenhouse gas (GHG) production in response to land use change mangrove wetlands elucidated underlying mechanisms by integrating environmental parameters community characteristics. In time period studied, substantially reduced organic matter content, richness diversity, CO 2 rates. Converting mangroves drier cover types, namely orchard vegetable field, significantly diminished reducing substrates (sulfide, Fe 2+ , NH 4 + ), network complexity stability, CH rates, while increasing N O contrast, these showed opposite trend following conversion flooded aquaculture pond. Overall GHG rate was 399.8 mg e kg −1 d which respectively decreased 68.83%, 69.86%, 30.84% orchard, Microbial stability were strongly related rates O, rather than can be better indicators specialized (CH production). Therefore, preserving “interaction” could important mitigate negative effects diversity loss caused human activities aquatic environments. Future research should consider conditions composition, interactions, gain comprehensive understanding functions.
