Dynamics of labile soil organic carbon during the development of mangrove and salt marsh ecosystems

TL;DR: In this article , the nitrogen and phosphorus cycling varied in mangrove and salt marsh, having significant implication on coastal waters, and the nitrogen transformation rates and microbiological activities were also investigated to explain the variability in nitrogen concentrations.

TL;DR: Wang et al. as discussed by the authors used a structural equation modeling (SEM) to part the direct and indirect effects of factors on soil organic carbon dynamics based on the covariance structures, and showed that environmental factors influenced carbon pools through different pathways.

TL;DR: In this paper, the authors tried to capture such capacity of soils and sediments of coastal natural ecologies (like estuary, mangrove, mudflat, tidal marsh, seagrass, lagoon, continental shelf etc.) and croplands collectively in a mechanistic way.

TL;DR: This work has suggested that several environmental constraints obscure the intrinsic temperature sensitivity of substrate decomposition, causing lower observed ‘apparent’ temperature sensitivity, and these constraints may, themselves, be sensitive to climate.

TL;DR: The relationship between soil structure and the ability of soil to stabilize soil organic matter (SOM) is a key element in soil C dynamics that has either been overlooked or treated in a cursory fashion when developing SOM models as discussed by the authors.

TL;DR: In this article, the authors quantified whole-ecosystem carbon storage by measuring tree and dead wood biomass, soil carbon content, and soil depth in 25 mangrove forests across a broad area of the Indo-Pacific region.

TL;DR: It is proposed that labile plant constituents are the dominant source of microbial products, relative to input rates, because they are utilized more efficiently by microbes, and become the main precursors of stable SOM by promoting aggregation and through strong chemical bonding to the mineral soil matrix.
