Abstract
Invasion-driven diversity reduction is often attributed to decreased resource availability, but this has rarely been examined. We tested whether the invasion of native grassland by the introduced grass, Bromus inermis, was associated with reduced diversity, increased standing crop (including roots), and decreased resource availability. Diversity and evenness were significantly lower in invaded stands, but richness was not significantly different. Both shoot and root mass were significantly greater in B. inermis stands, suggesting that resource demand should be higher. Light penetration and soil moisture were significantly lower beneath B. inermis. In contrast, most nutrients (including available N) did not vary between vegetation types. Some nutrients (P, K, Ca, and Mn) were significantly more abundant beneath B. inermis, possibly reflecting the invader’s tendency to invade lower landscape positions. Overall, the results are consistent with invasion-driven diversity reduction being caused by increased resource demand and decreased availability of light and water.

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
