Population structure and microphylogeographic patterns of dolly varden (Salvelinus malma) along the Yukon North Slope
Bibliographic record
Abstract
This study investigated the genetic relationships among closely adjacent populations of dolly varden charr, 'Salvelinus malma', to infer recent evolutionary events on the Yukon north slope. Specifically, microphylogeographic patterns were ascertained, relationships among different life history types of charr were determined, and the potential role of dispersal and philopatry on past and present gene flow was assessed. The possibility of employing genetic markers for stock discrimination and for conservation were also examined. Microsatellite and mitochondrial D-loop data on eight populations of 'S. malma' were concordant, revealing that gene flow was restricted between drainages but common among sites within drainages. Two phylogroups were observed in the Firth drainage, but the other three drainages were dominated by a single phylogroup. Furthermore, the Firth drainage contained the highest genetic diversity, while the other drainages possessed a subset of the variation found in it. These results suggest that recolonization of the Yukon north slope likely came from Alaskan populations and that the Firth drainage should receive priority for conservation.

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.
