The effect of experimental warming on the root-associated fungal community of <i>Salix arctica</i>
Bibliographic record
Abstract
The effect of experimental warming on the root-associated fungal community of arctic willow (Salix arctica) was studied in three distinct habitats at a tundra site in the Canadian High Arctic. Plots were passively warmed for 5-7 years using open-top chambers and compared to control plots at ambient temperature. Fungal communities were assessed using terminal restriction fragment length polymorphisms. We found the following: (1) the root-associated fungal community in these high arctic tundra habitats is highly diverse; (2) site and soil characteristics are the most important drivers of community structure and (3) warming increased the density of different genotypes on individual root sections but has not (yet) affected the composition, richness or evenness of the community. The change in genotype density in the warmed plots was associated with an increase in PCR amplification efficiency, suggesting that increased C allocation belowground is increasing the overall biomass of the fungal community.

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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
