Genetic connectivity of boreal woodland caribou (Rangifer tarandus caribou) in central Canada
Bibliographic record
Abstract
Delineating population units is essential for the conservation and management of a species. Applying a genetic approach to delineate units, this study identifies genetic population structure, and landscape resistance to gene flow, of the nationally threatened boreal woodland caribou (Rangifer tarandus caribou) across the ecotypes’ southern range in Saskatchewan. Three genetic clusters were delineated across the study area, with moderate genetic connectivity identified with Manitoba. Isolation-by-distance was found to be significant across Saskatchewan, and within each genetic cluster. Gene flow across clusters in Saskatchewan was high (FST = ~0.01), with genetic connectivity being lowest for the south-central cluster surrounding Prince Albert National Park (FST = ~0.03). Resistance to gene flow was identified with the following landscape variables: water, forestry, roads, wildfire, and low suitability habitat. Careful consideration of these variables in range planning will help to maintain genetic connectivity of boreal caribou across its southern range in Saskatchewan.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
