Abstract

fetched live from OpenAlex

The invasive emerald ash borer (Agrilus planipennis) (EAB) is causing widespread ash (Fraxinus spp.) mortality in 25 U.S. states and two Canadian provinces. We investigated the impact of EAB on coarse woody debris (CWD) volume across 24 sites in western and central Ohio, USA, representing a chronosequence of ash mortality, quantified by the year ash mortality reached 25% (Year25�ad). CWD volume averaged 60.36 m3/ha, and was positively associated with total (live plus dead) ash basal area (BA), but was not greater in sites where ash death occurred earlier. For the volume of CWD in the first, least-rotted, decay class, stepwise regression revealed that both ash BA and Year25�ad were significant predictors; sites with more ash BA and where ash mortality had occurred earlier had more class 1 CWD. Additionally, class 1 CWD in those early mortality sites was primarily (87%) ash, compared to 40% ash in sites with more recent ash mortality. This large influx of CWD, particularly ash CWD, combined with future inputs from ash that are still standing, will elevate CWD volume in the near future, especially in sites with greater ash basal area.

Teacher imitation

Not 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.
