The effect of Myriophyllum aquaticum on freshwater bodies in British Columbia
Bibliographic record
Abstract
Myriophyllum aquaticum is an invasive plant species originating from the Amazon River and is currently found in British Columbia. We hypothesized that freshwater sources with Myriophyllum aquaticum would have lower dissolved oxygen content compared to areas without Myriophyllum aquaticum . During this experiment, 40 water samples were collected from each of our four sites: Serpentine Fen (Surrey, B.C.), Nicomekl River (Surrey, B.C.), Alpine Garden Pond and Meyer Glade at the University of British Columbia Botanical Garden (Vancouver, B.C.). Serpentine Fen had Myriophyllum aquaticum while the other three sites were control sites. The dissolved oxygen content (mg/L) was measured with an oxygen meter and recorded for comparison. When comparing the data from Serpentine Fen to Nicomekl River, Alpine Garden Pond and Meyer Glade, a paired t-test was used. P-values of 2.2753E-22, 1.082E-29 and 9.0394E-29 were obtained for these sites. Since they are all less than 0.05, the null hypothesis was rejected and support was provided for the alternate hypothesis that Myriophyllum aquaticum decreases the dissolved oxygen content in freshwater bodies. The results also suggest that a decrease in temperature may increase the dissolved oxygen content because numerous biota cannot survive the colder temperatures, thus less oxygen is being used.

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.
