Photosynthesisrespiration balance of a prairie ecosystem: North and South Saskatchewan River watersheds
Bibliographic record
Abstract
The location of the hypothesized "missing carbon sink" has become a subject of open debate in the scientific community, with North America considered to be a prime location for such a sink. While forest ecosystems are considered to be the major candidate, Prairie ecosystems, with their large capacity to store carbon in their soils, may or may not be an ancillary candidate. The North and South Saskatchewan River watersheds are a prime example of such prairie ecosystems and, with this in mind, I attempted to quantify their role as potential sources or sinks of atmospheric CO2. The sequestration of atmospheric CO2 by plants via photosynthesis requires that water and CO2 be utilized at a specific ratio called the water utilization efficiency (WUE). Thus, knowing the hydrological budget of a watershed, specifically the transpiration component, it is possible to calculate its net primary productivity (NPP). This, combined with biological model estimates for heterotrophic soil respiration (Rh), enables evaluation of source and sink tendencies in the watershed. (Abstract shortened by UMI.)

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.
