Genetic divergence and phylogeography of the alpine plant taxon <i>Onobrychis transsilvanica</i> (Fabaceae)
Bibliographic record
Abstract
Although the Carpathians represent one of the main elements of the European Alpine System and an important area of endemism, only a few phylogeographic studies concerning this region have focused on the detailed intraspecific variation in alpine plant species. Using two molecular marker systems, we (1) aimed to elucidate the controversy concerning the status of the endemic Carpathian taxon Onobrychis transsilvanica Simonk. in relation to the more widespread Onobrychis montana DC. and (2) determined the phylogeographic structure of O. transsilvanica within the Carpathians. For O. transsilvanica, our data suggest either a recent postglacial speciation with incomplete lineage sorting or genetic divergence followed by subsequent continuous gene flow during the glacial period. The genetic structure of the complex does not support O. transsilvanica as a distinct species from O. montana. Within the Carpathians, the extant populations of O. transsilvanica comprise two major allopatric lineages, which have been isolated from each other for a long period of time. Unexpectedly, the major genetic break was not in line with a classical biogeographical boundary in the Carpathians but rather separated a group from the southwestern edge of the mountains. We also discovered an additional divergent haplotype lineage, with weaker genetic support, within the O. transsilvanica populations.

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.
