Emission of Nitrogen Gas, Nitrous Oxide, and Carbon Dioxide on Rehydration of Dry Feathermosses
Bibliographic record
Abstract
Two experiments were conducted to examine the fate of N in feathermosses when mosses were dehydrated and then rewetted. In the first experiment, dry feathermoss shoots were sealed in containers where the N 2 was replaced by He. After rewetting and incubating for 20 h, gas in the containers had significant amounts of N 2 and N 2 O and had elevated levels of CO 2 compared with mosses maintained in a moist condition or dried mosses that had not been rewetted. In the second experiment, samples of feathermoss were subjected to five dry–wet cycles. By the fifth cycle, there was a 9% reduction in mass of the moss and a similar decline in quantity of N. The results of this study suggest that in forests undergoing dry–wet cycles, there is a potential for N volatilization directly from the moss layer. After drying and rewetting, the moss releases sugars and soluble forms of N into the substrate, creating a suitable environment for aerobic denitrification. Thus, more N is lost from an already N‐deficient ecosystem.

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.
