PHYLOGEOGRAPHY AND CONSERVATION GENETICS OF SOUTHERN FLYING SQUIRRELS (GLAUCOMYS VOLANS) FROM NOVA SCOTIA
Bibliographic record
Abstract
Mitochondrial cytochrome-b (Cytb) and control region (CR) sequence data were used to investigate the phylogeography of the disjunct population of southern flying squirrels (Glaucomys volans) from Nova Scotia. Consistent with previous studies, there is little differentiation in Cytb sequences (0–1.3% sequence divergence) across the entire range of G. volans in North America. Nested clade phylogeographic analysis of CR sequences (which exhibited 0.5–5.7% sequence divergence) provided a finer scale of differentiation and allowed for inferences to be made regarding the phylogeographic history of the population from Nova Scotia. We propose that G. volans rapidly expanded its range from a southern refugium after the Wisconsin glaciation (∼ 12,000 years ago) and was then isolated in southwestern Nova Scotia during subsequent climactic fluctuations. More specifically, the population from Nova Scotia was isolated from extant populations in Ontario by the loss of intermediate populations. Although the population of G. volans in Nova Scotia would not be considered an evolutionarily significant unit under some definitions, examination of CR sequence data suggests that this population may nevertheless be diverging from other 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.
