Macroalgal and seagrass species generate variable amounts of recalcitrant dissolved organic carbon in coastal Japan

Communications Earth & Environment
Dissolved organic carbon released from marine macrophytes is an important carbon sequestration pathway, but its recalcitrant fraction remains poorly quantified.

Effect of Simulated Drying-Rewetting Cycles on Soil Respiration and Dissolved Organic Carbon and Nitrogen Stability in Zoige Alpine Wetlands

Shuitu baochi yanjiu, 2020
With the global climate change, extreme droughts and heavy precipitation events occur frequently, thus soils are undergoing more complicated and frequent drying-rewetting cycles, which have an important effect on soil respiration.

Characterization of Dissolved Organic Matter in River Water by Conventional Methods and Direct Sample Analysis-Time of Flight-Mass Spectrometry

Journal of Chemistry, 2016
The dissolved organic matter in surface waters is composed of fractions of different molecular weight and polarity, characteristics that determine their capacity for complexing different types of pollutants and their environmental impact.

Latitudinal Gradients in Degradation of Marine Dissolved Organic Carbon

PLoS ONE, 2011
Heterotrophic microbial communities cycle nearly half of net primary productivity in the ocean, and play a particularly important role in transformations of dissolved organic carbon (DOC). The specific means by which these communities mediate the transformations of organic carbon are largely unknown, since the vast majority of marine bacteria have not ...
