Dynamics of above- and belowground organic matter in a high latitude macrotidal saltmarsh
Bibliographic record
Abstract
Seasonal variations in above-and belowground biomass were examined over the 1994 growing season (May to October) in the 3 major plant zones of a saltmarsh located on the Bay of Fundy.Standing crop of aboveground biomass was measured over the growing season.Belowground samples were processed at depth intervals of 2 cm, providing high-resolution vertical profiles to a depth of 40 cm.Spartina alterniflora showed evidence of the translocation of belowground biomass to aboveground tissue in the early part of the growing season, when the rate of aboveground growth is at a maximum.Shifts in S. alterniflora organic matter storage were most dynamic in the surface 16 cm.Biomass translocation generally was not significant in the S. patens stands, where the rate of aboveground growth was consistent throughout the growing season.All seasonal changes associated with Plantago maritima biomass seem to occur before July, since no changes in above-and belowground biomass were observed between July and October.P. maritima contributes the least to marsh soil organic matter.

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.
