Abstract
To explore the beneficial qualities or detrimental consequences of cultureable soil yeasts, it is important to understand which physicochemical soil properties most impact populations of these unicellular fungi in their natural habitat. The goal of this study was to determine which soil properties dictate yeast numbers in pristine sandy, low nutrient soils within a semi-arid region. A correlation matrix of the data obtained for 19 different environmental variables indicated a negative correlation between soil pH and yeast numbers. Using general regression models, it was demonstrated that soil pH and copper concentration were the 2 variables that correlated best with soil yeast counts in these soils. However, soil moisture content was found to be the environmental factor with the most impact on cultureable actinomycetes and heterotrophic microbes. The study also demonstrated that divalent cation availability might impact the size of both yeast and prokaryote populations in these soils.

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
