In northern Israel freshwater wetland sediments, EA3 and EN showed distinct methane accumulation patterns under carbon enrichment, with EA3 reaching 18.8 mmol CH4 kg-1 during Days 22–29 and EN peaking Days 29–36.
- Why it matters: Methane buildup in wetlands depends on coupled organic matter, sediment chemistry, and microbes, but how these factors diverge across habitats under labile-carbon addition is not well resolved.
- What they did: They combined depth-resolved field measurements across four habitats (Rock-Eval, porewater chemistry, oxygen profiling, and mcrA amplicon sequencing) with 36-day sucrose-amended bottle incubations using sediments from EA3 and EN.
- The result: EA3 displayed a transient CH4 maximum and methane proportions that rose before a large output increase, while EN’s highest collected CH4 occurred later; community and chemical oxygen demand trajectories also differed, supporting methanogenic potential even in low-CH4 sediment.
