The global warming-driven poleward expansion of mangrove habitats (e.g., Avicennia germinans and Rhizophora mangle) into temperate salt marshes Spartina alterniflora Juncus roemerianus) has been shown to alter coastal soil organic carbon (SOC) storage. However, the taxa-specific consequences this vegetation shift on origin size SOC sub-fractions (particulate OC (POC); mineral-associated (MAOC); reactive iron-associated (FeR-MAOC)) remain largely unexplored. In study, we used a particle size-based fractionation method compare quantity δ13C composition bulk each in cores collected from Apalachicola Bay barrier islands Florida, USA, highest latitude where monospecific communities all four aforementioned plants co-occur. Depth-dependent variation clearly showed replacement S. by mangroves, as well reciprocal substitutions J. roemerianus, probably driven changes wetland elevation. Higher burial rates suggested that soils were principally developed deposition. contrast, comparatively lower but higher stocks marsh illustrated subsurface input roots.

Abstract. Reactive iron (Fe) oxides are vital for long-term soil or sediment organic carbon (SOC) storage. However, the patterns and drivers of Fe-associated (Fe-OC) over global geographic scales under various ecosystem types remain controversial. Here, we provided a systematic assessment distribution determinants Fe-OC content its contribution to SOC (fFe-OC) by assembling dataset comprising 862 observations from 325 sites in distinct ecosystems. We found that across ecosystems ranged 0 83.3 g kg−1 (fFe-OC % 82.4 %), reflecting high variability pool. contents varied with type being greater wetlands molar ratio / dithionite-extractable Fe (Fed) compared marine terrestrial Furthermore, fFe-OC was significantly lower than other due rich (OC). In contrast climate variables pH, random forest modeling multivariate analysis showed : Fed were predominant predictors ecosystems, whereas primary driver Based on upper estimates storage types, further estimated 83.84 ± 3.8, 172.45 8.74, 24.48 0.87 Pg preserved association wetland, terrestrial, respectively. Taken together, our findings highlighted importance reactive preservation, their controlling factors specific.
