Rapid cycling of recently fixed carbon in a Spartina alterniflora system: a stable isotope tracer experiment
Carbon dynamics in vegetated ecosystems are influenced by plants, belowground bacteria, and their interactions. Consequently, quantifying the fate of new plant production, identifying bacterial carbon sources, and evaluating plant—microbe interactions can provide insight to carbon cycling and storag...

description | Carbon dynamics in vegetated ecosystems are influenced by plants, belowground bacteria, and their interactions. Consequently, quantifying the fate of new plant production, identifying bacterial carbon sources, and evaluating plant—microbe interactions can provide insight to carbon cycling and storage. To follow short-term carbon transformations in a Spartina alterniflora—soil system, we applied ¹³C-labeled CO₂ to aboveground leaves and chased it belowground into roots and bacterial lipids. Plant mesocosms were exposed to ¹³CO₂ for 0, 1, 3, or 6 h. Incorporation of ¹³CO₂ by plants and soil microbes was measured immediately after the incubation (Day 0) and 24 h later (Day 1). During a 24 h period, 41–64 % of the ¹³CO₂ fixed by S. alterniflora was retained in leaves, 2.7–6.4 % was transferred to roots, and 30–55 % was lost via respiration. Small fractions of ¹³C assimilated by aboveground leaves were detected belowground in bacterial lipids on Day 1. Enrichment of lipids specific to sulfate reducing bacteria (10-methyl C16:0, cy-C17:0) indicated tight coupling between aboveground plant production and belowground anaerobic metabolisms. Overall, we found that a substantial fraction of new production was returned to the atmosphere within 24 h and that belowground bacteria were tightly coupled to plant dynamics. |
