Parental Plant Elevation Does Not Affect Nonnative Poa annua's Seed Germination and Propagation Potential
Bibliographic record
Abstract
Nonnative species are a threat to biodiversity as their numbers are increasing in protected areas globally, impacting many ecological processes such as hydrological cycles, fire regimes, and competition. These species possess traits that ease their progression into alpine habitats, which could be a threat to rare and endemic plants in these areas. A prime example of this is in the Gaspésie National Park (Québec) where many nonnative species, such as Poa annua, are progressing in elevation, establishing in alpine habitats inhabited by rare and endemic species. In the case of this study, the impacts of elevation on parental plants and date of collection on seed germinability was determined for mature seeds of P. annua on three mountains in the Gaspésie National Park. Elevation as well as the date of collection did not influence germination of seeds of P. annua, and total germination remained very high (>80%) at high elevations. Therefore, because seed germination is not affected by maternal plant elevation, we assume that the abundance of P. annua may increase in disturbed alpine areas, and management strategies should be developed to counter or mitigate the effects of these invasions.

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.
