Reproductive biology and floral variation in the endangered Braya longii and threatened B. fernaldii (Brassicaceae) : implications for conservation management of rare plants
Bibliographic record
Abstract
The closely related, endangered Braya longii and threatened Braya fernaldii (Brassicaceae) are endemic to the limestone barrens of the Great Northern Peninsula of Newfoundland. This project determines potential breeding systems, levels of population differentiation, potential hybridization between these species and implications for conservation management. Morphological species differences are also summarized to ensure proper identification of new populations. Results indicate field identification using only single morphological characters is insufficient to unambiguously identify species. Both species were found to be primarily autogamous but B. longii has a greater potential for outcrossing than B. fernaldii. Cleistogamy was found to occur within some populations of B. fernaldii, but not in B. longii. Evidence of population differentiation in floral morphology was found for both species and potential hybridization was indicated by floral morphology and hand-pollinations. The results of this study provide guidance for potential conservation management tools and must be addressed before reintroduction and population restoration are implemented.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
