The role of cotton-grass (Eriophorum vaginatum) in the cardon dioxide and methane dynamics of two restored peatlands in eastern Canada /
Bibliographic record
Abstract
The role of Eriophorum vaginatum in carbon dioxide (CO 2) and methane (CH4) dynamics of two restored peatlands in eastern Canada was examined. Sites were established in Riviere-du-Loup, Quebec from May to October of 1999 and 2000, and Shippagan, New Brunswick from May to October of 2001. CH4 emissions from E. vaginatum collars were positively related to maximum photosynthesis in 1999 and 2001, when the water table was close to the surface. CH4 emissions were also positively related to end of season above ground plant biomass at both sites. CH4 emissions from E. vaginatum collars ranged from -0.015 to 14.7 mg CH4-C m-2 h-1 at Riviere-du-Loup and -0.15 to 5.4 mg CH4-C m -2 h-1 at Shippagan. It is likely that E. vaginatum provides substrate for methanogenesis through plant production and acts as a conduit transporting CH4 to the atmosphere. Patterns of NEE from E. vaginatum depended on site-specific and year-specific conditions. E. vaginatum was a net sink for CO2 at high and low light levels at Shippagan, and a net source of CO2 at low light levels at Riviere-du-Loup.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
