Abstract
Northern lakes, for which we have little long‐term data, are predicted to experience profound impacts with greenhouse warming. In order to assess the usefulness of chrysophytes as paleoenvironmental indicators, stomatocysts were enumerated from the surface sediments of 51 Alaskan lakes distributed along a strong climatic gradient. A total of 142 cyst morphotypes were described using light microscopy, of which 13 are believed to be new forms. Principal components analysis of the stomatocyst assemblages showed a limited amount of variation (Λ 1 = 0.11, Λ 2 = 0.09). However, redundancy analysis identified total phosphorus (TP), sodium (Na), and altitude (ALT) as significant variables in terms of their ability to describe the distribution of stomatocysts. Major ion and nutrient concentrations were also found to be strong predictors of diatom variation from the same lake set. In comparison to the diatom assemblages from the same lakes, the cysts were less abundant and showed a lower amount of species variation. Reasons for the lack of variation may be due to the predominance of unornamented and collective category cysts (i. e. cysts which cannot be differentiated under the light microscope).

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 it
