Seasonal grazing by Canada geese (<i>Branta canadensis</i>) on South Island highcountry pasture

Abstract
Sclerotium cepivorum is the casual agent of onion white rot. Dormancy is the term used here to describe why sclerotia sometimes do not germinate in response to onion root exudates, e.g. diallyl disuphide (DADS). Overseas studies suggest that dormancy lasts 1-3 months. We tested for dormancy using three isolates of S. cepivorum in two soil types. We compared two methods. The first one involved removing sclerotia, after conditioning, into Petri dishes before application of DADS. The second involved applying DADS to sclerotia buried in bags in the field. We found that dormancy lasted a minimum of 8 weeks and occurred in all isolates tested. Soil type had minimal influence on the breaking of dormancy. The method involving Petri dishes was prone to problems caused by contaminating fungi, which grew over the sclerotia and made the scoring of germination difficult. The alternative method was more effective and more closely imitated field conditions. This work continues using a greater number of isolates and supports ongoing studies on the use of DADS for disease control.

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.
