PHYLOGEOGRAPHY OF KEEN'S MOUSE (PEROMYSCUS KEENI) IN A NATURALLY FRAGMENTED LANDSCAPE
Bibliographic record
Abstract
Phylogenetic methods were used to analyze cytochrome-b sequences (n = 257; 560 base pairs) from Peromyscus keeni (Keen's mouse) collected from 23 islands of the Alexander Archipelago and 6 mainland locations in southeast Alaska and western Canada. Although P. keeni is ubiquitous across this region, island populations are genetically distinctive. Genetic structure of extant populations of P. keeni appears to have been more heavily influenced by vicariance than post-glacial colonization. Populations of P. keeni might have survived in coastal refugia during the last glacial maximum (15 × 103 years ago). Island area was significantly correlated with 2 of 3 genetic diversity measures whereas island isolation was not. Areas with divergent populations were discovered, but were largely inconsistent with 3 of 5 currently recognized subspecies. Cryptic variation was detected in 8 areas not previously identified by morphologic analyses.
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.
