Insect visitation and pollination of a culturally significant plant, Hopi tobacco (Nicotiana rustica)
Bibliographic record
Abstract
Nicotiana rustica is a monecious member of the Solanaceae family, distributed across North America where it is grown for ceremonial purposes. Flowers of N. rustica open in the morning and are receptive to pollen until the following day. This study investigates the role of diurnal and nocturnal pollinators in reproductive success (seed weight, seed set, seediness) and insect visitation rate in N. rustica in eastern North America using floral bagging techniques. Results show that N. rustica benefits most from open (open day and night) and day open (closed at night) pollination. Fruit weight was higher with the presence of diurnal pollinators; fruit set and seediness were unaffected. Video recordings show that the most abundant floral visitors are small bees. These results provide information that will be useful in making management decisions surrounding the continued growth of this culturally significant plant species.
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.

Full frame machine prediction
Teacher imitationNot 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.
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 source (direct Gemma or distilled Codex), not a consensus.
