Population genetics of Bull Trout ( <i>Salvelinus confluentus</i> ) in the Upper Athabasca river basin
Bibliographic record
Abstract
Abstract Across its native range, Bull Trout ( Salvelinus confluentus ) extent and abundance are in decline due to historic overharvest and habitat degradation. Because Bull Trout are dependent on extensively connected, cold, clean headwater habitats, fragmentation from land use changes causes difficulty when determining the true extent and health of their populations, with Bull Trout of Alberta’s Eastern Slope region being no exception. Across this region, 431 Bull Trout from 20 sites were sampled from the Athabasca and Saskatchewan River basins and compared using 10 microsatellite loci to characterize within- and among-population genetic variation. The Saskatchewan and Athabasca River basins contained similar levels of heterozygosity but were differentiated from one another. Within the Athabasca River basin, five genetically differentiated clusters were found. Additionally, no isolation-by-distance pattern was observed between these sites. These results suggest these populations have ample genetic diversity, but genetic differentiation should be considered when deciding whether and how to alter connectivity between populations.

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.
