Surface-sediment diatom assemblages and water chemistry from 42 subarctic lakes in the southwestern Yukon and northernBritish Columbia, Canada
Bibliographic record
Abstract
Modern diatom assemblages were related to surface-water chemistry from 42 lakes in the southwestern Yukon and in northern British Columbia. The lakes were alkaline (pH ranged from 7.5 to 9.4) with high specific conductance (mean = 379 µS cm-1). The lakes spanned a relatively wide range of trophic conditions, with the majority being oligotrophic or meso-eutrophic. Lake water depth, alkalinity, lake surface area, and Mg accounted for most of the variation in the diatom assemblages. Diatom assemblages most closely resembled those of the southern interior of British Columbia, where high conductance lakes are numerous, although many of the taxa were common to other northern regions, including Siberia, Alaska, and other parts of the Yukon. These data may be used in conjunction with other data from northern regions, including the Yukon and Alaska, to provide broader descriptions of environmental preferences of diatom taxa by extending the range of environmental variables such as alkalinity and specific conductance.

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.
