Impacts of Climate Change on Blue Carbon Stocks and Fluxes in Mangrove Forests

Forests, Journal Year: 2022, Volume and Issue: 13(2), P. 149 - 149

Mangroves store blue carbon (693 Mg CORG ha−1) disproportionate to their small area, mainly (74%) in deep soil horizons. Global stock estimates for mangroves (5.23–8.63 Pg CORG) are equivalent 15–24% of those the tropical coastal ocean. Carbon burial mangrove soils averages 184 g m−2 a−1 with global (9.6–15.8 Tg a−1) reflecting importance sequestration. Extreme weather events result losses and declines cycling export.

Mangrove-associated Pacific oysters (Magallana gigas) influence estuarine biodiversity

NeoBiota, Journal Year: 2025, Volume and Issue: 98, P. 1 - 26

Published: March 7, 2025

Estuarine ecosystems are often characterised by endemic foundation organisms which facilitate ecosystem interactions and processes established over millennia. Introduction of non-native species can significantly alter ecological communities functions. Here, we assessed the effects introduced, reef-forming Pacific oyster Magallana gigas , within a temperate Australian mangrove-dominated estuary. Specifically, investigated whether mangrove-attached M. reefs influenced intertidal fish invertebrate communities, foraging behaviour. We measured contrasted benthic structure faunal fringing bare sediment, Avicennia marina mangrove reef habitats using combination quadrats, fyke nets remote unbaited video (RUV) surveys. showed no impacts on pneumatophore density or morphology, but were positively associated with higher seedling densities. Furthermore, community metrics (e.g. richness, biomass, length) typically in compared to other habitats. However, several mobile, predominantly detected reefs, including exotic gobies European shore crabs Carcinus maenas declared marine pest. Overall, found that forests biodiverse fisheries-targeted species, also facilitated species. These outcomes highlight some pros cons complexity managing estuaries globally where oysters increasingly co-occur habitat-forming

Microbial functional assemblages predicted by the FAPROTAX analysis are impacted by physicochemical properties, but C, N and S cycling genes are not in mangrove soil in the Beibu Gulf, China

Ecological Indicators, Journal Year: 2022, Volume and Issue: 139, P. 108887 - 108887

Mangroves and their global significance in climate change based on the storage of blue carbon release CO2, CH4, N2O have attracted great attention. Microbial communities functions are essential for biogeochemical cycle (C), nitrogen (N), sulfur (S). Therefore, assessment microbial mangrove habitats, which suffer from different external environments, is necessary to evaluate unique ecological service functions. In present work, functional profiles four reserves (one sandy three muddy, Beibu Gulf, China) were detected by 16 s RNA gene amplicon-based Functional Annotation Procaryotic Taxa (FAPROTAX) analysis as well C, N, S q-PCR chips. The FAPROTAX showed that metabolic potential cycling indicated a difference regions. Moreover, some groups involved significantly correlated with physicochemical characteristics.

Refining the Global Estimate of Mangrove Carbon Burial Rates Using Sedimentary and Geomorphic Settings

Geophysical Research Letters, Journal Year: 2022, Volume and Issue: 49(18)

Published: Sept. 21, 2022

Abstract This study provides updated analysis of multi‐decadal mangrove organic carbon (OC) burial rates. The available data indicate mangroves bury 138.6 (120.3–158.8, 95% C.I.) g OC m −2 yr −1 locally, or 20.18 (17.52–23.12) Tg globally. We contend that this common approach upscaling from a single local‐scale rate obscures critical environmental differences in By implementing recently formalized, spatially explicit global typology, we find carbonate setting have lower rates than terrigenous settings, and based on representative for sedimentary alone combination geomorphic increased the scale annual to 22.10 (18.26–26.05) 24.17 (19.77–25.50) , respectively. propose future work should focus less consolidating confidence interval rates, instead explore drivers spatial variability settings.
