Evaluating out-planting success and mycorrhizal status of endangered Geum peckii Pursh (Rosaceae), the Eastern Mountain Avens, in Nova Scotia
Bibliographic record
Abstract
Geum peckii (Rosaceae), the Eastern Mountain Avens, is a small herbaceous plant that is listed as endangered federally and provincially. In Canada, this species is found in bogs on Brier Island and Harris Lake, Digby County, Nova Scotia. The only other population outside of Canada is in New Hampshire (USA). To enhance conservation research of this species, a seed sample from the native species seed bank at Acadia University was used to establish a plant tissue culture of G. peckii plants. Survival of out-planted material was then assessed in both the greenhouse and the field. The field test site was within 20km of the existing plant populations in Digby County. Our study also revealed that G. peckii grows in association with arbuscular mycorrhizal fungi (AMF). During out-planting, plants received a mycorrhizal inoculum with the goal of enhancing survival. We used either a commercial mycorrhizal inoculum, or a native inoculum. Control plants were left untreated. Survival was 97-100 % among all the treatments by the end of the 2016 planting season. The results to date underscore the potential value of seed banking for protection of endangered native plant species. This study marks the first time in Nova Scotia that an endangered plant species has been successfully retrieved from seed bank storage, propagated by tissue culture, and out-planted back into a natural habitat.

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.
