Abstract

fetched live from OpenAlex

This chapter focuses on diffuse knapweed ( Centaurea diffusa ) and spotted knapweed ( Centaurea maculosa ) invading rangelands and grasslands in Canada, and provides an overview of the insects ( Agapeta zoegana, Chaetorellia acrolophi, Cyphocleonus achates, Larinus minutus, Larinus obtusus, Metzneria paucipunctella, Pelochrista medullana, Pterolonche inspersa, Sphenoptera jugoslavica, Terellia virens and Urophora spp.) and fungi ( Sclerotinia sclerotiorum and Puccinia jaceae [ Puccinia hieracii var. hieracii ]) that have been used for their management, and the evaluation of effectiveness of these biological control agents. Future research prospects are recommended.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
