Abstract Our knowledge of the factors that can influence stock organic carbon (OC) is stored in soil seagrass meadows evolving, and several causal effects have been used to explain variation stocks observed at local national scales. To gain a global‐scale appreciation drivers cause OC stocks, we compiled data on published species‐specific traits from monospecific mixed multiple geomorphological settings. Species identity was recognized as an influential driver despite their large intraspecific variation. The most important species associated with were number leaves per shoot, belowground biomass, leaf lifespan, aboveground lignin, breaking force plus coastal geomorphology area, particularly for lagoon environments. A revised estimate global average 20 cm depth 15.4 Mg C ha −1 lower than previously reported. largest still recorded Mediterranean meadows. results specifically identify Posidonia oceanica and, more generally, persistent key providing climate regulation services, priority conservation this specific ecosystem service.

Abstract Seagrass conservation is critical for mitigating climate change due to the large stocks of carbon they sequester in seafloor. However, effective and its potential provide nature-based solutions hindered by major uncertainties regarding seagrass extent distribution. Here, we describe characterization world’s largest ecosystem, located The Bahamas. We integrate existing spatial estimates with an updated empirical remote sensing product perform extensive ground-truthing seafloor 2,542 diver surveys across tiles. also leverage assessments movement data obtained from instrument-equipped tiger sharks, which have strong fidelity ecosystems, augment further validate predictions. report a consensus area at least 66,000 km 2 up 92,000 habitat Bahamas Banks.

Coastal vegetated ecosystems are acknowledged for their capacity to sequester organic carbon (OC), known as blue C. Yet, C global accounting is incomplete, with major gaps in southern hemisphere data. It also shows a large variability suggesting that the interaction between environmental and biological drivers important at local scale. In southwest Atlantic salt marshes, account space occupied by crab burrows, it key avoid overestimates. Here we found marshes store on average 42.43 (SE = 27.56) Mg OC·ha-1 (40.74 2.7) belowground) bury 47.62 g OC·m-2·yr-1 (ranging from 7.38 204.21). Accretion rates, granulometry, plant species burrowing crabs were identified main factors determining belowground OC stocks. These data lead an updated estimation stocks of 185.89 (n 743; SE 4.92) burial rate 199.61 193; 16.04), which lower than previous estimates.

Abstract Seagrass meadows are important sinks for organic carbon and provide co-benefits. However, data on the stock in seagrass sediments scarce many regions, particularly The Bahamas, which accounts up to 40.7% of documented global area, limiting formulation blue strategies. Here, we sampled 10 across an extensive island chain Bahamas. We estimate that Bahamas store 0.42–0.59 Pg top-meter with accumulation rate 2.1–2.9 Tg annually, representing a substantial hotspot. Autochthonous decreased from ~1980 onwards, concomitant increases cyanobacterial mangrove contributions, suggesting disturbance ecosystems, likely caused by tourism maritime traffic activities.

Abstract Since seagrasses are efficient sinks for marine organic carbon, there is growing interest in incorporating seagrass protection and restoration into climate mitigation schemes, that is, offering credit accumulated carbon to offset dioxide emissions. However, patterns drivers of storage by not well resolved, especially at scales relevant management decisions. Here, we quantified geographic variation standing stocks sedimentary (Mg C org ha −1 ) associated with along the northern Florida Gulf Coast using field surveys sediment cores. We measured plant biomass, composition each core. Using a multivariate modeling approach, evaluated relative importance ecological, physical, oceanographic, seascape drivers, developing first spatially explicit predictions seagrass‐associated this region. Applying model confirmed beds potential recovery areas, also estimated value conservation as resulting stock enhancement per hectare (Δ Mg ). found stored sediments varied considerably across region, significantly increasing cover, proximity oyster reefs, distance from river outlets, highlighting synergies coordinated management. current could offer nearly double emphasizing restoration. Our results have important implications management, restoration, understanding biogeographic ecosystem services.
