Tidal flats are widely distributed and provide a variety of ecosystem services. Nevertheless, the consequences tidal flat loss implications for services such as carbon (C) sequestration have not been assessed. In unvegetated ecosystems, sediment is most important reservoir, similar to that vegetated coastal wetlands (i.e., mangroves, salt marshes, seagrass). We examined C stocks accumulation rate (CAR) reported from 123 locations around world compared these results with data seagrass...
The ubiquitous occurrence of microplastics in coastal habitats is widely reported. As an anthropogenic material with high carbon content, the contribution to sediment stock still unassessed. Here, we report pattern (20–2000 μm) and estimate their different sediments Hong Kong, a metropolis Pearl River estuary part Greater Bay Area population 70 million. Our data reveal that are more concentrated surface vegetated sediments. We also at present from contributes between 0.001% 1.197% pool...
Cold seeps are hotspots of biodiversity. However, the quantification microbial diversity, particularly that microeukaryotes, remains scarce and little is known about active groups. In this study we investigated diversity activity prokaryotes microeukaryotes in Haima cold seep sediments northern South China Sea using both DNA (whole community) RNA (active signatures. We found that, general, had lower sediment than non-seep regions while showed opposite pattern. This finding could be explained...
Analyzing the molecular composition change of dissolved organic matter (DOM) during transportation in estuaries can enhance our understanding fate DOM. However, impact hydrologic conditions resulting from large river plumes on DOM cycle are less explored, and previous studies were insufficient to capture that occur process. In this study, we used a range bulk optical techniques, as well Fourier transform ion cyclotron resonance mass spectrometry (FT-ICR MS), determine concentration...
Abstract Coastal ecosystems are recognized as important carbon reservoirs. However, assessments of coastal dioxide (CO 2 ) fluxes often neglect unvegetated tidal flats, particularly in peri-urban areas. This study investigated the gross primary production (GPP), net (NPP), and total respiration (TR) three flats Hong Kong, one largest cities South China, during both summer winter seasons to understand their CO fluxes. Results showed that GPP was significantly higher than summer. no...
