Complete mitochondrial genomes of <i>Callospermophilus lateralis</i> and <i>Urocitellus richardsonii</i> (Rodentia: Sciuridae)
Bibliographic record
Abstract
The complete mitochondrial genomes of Callospermophilus lateralis and Urocitellus richardsonii (Rodentia: Sciuridae) were sequenced to analyze the gene arrangement and discuss the phylogenetic relationship of species within the Xerinae. The genomes are circular molecules of 16,457 bp and 16,460 bp in length, respectively, including the 37 genes typically found in other squirrels. The AT content of the overall base composition is 63.2% for both species. The length of control region for C. lateralis is 1009 bp with 62.8% AT content; the corresponding values for U. richardsonii are 1012 bp and 62.0% AT content. In BI and ML phylogenetic trees, the monophyly of the family Sciuridae and subfamilies Callosciurinae and Sciurinae are well supported, but the monophyly of Xerinae is not supported. Within the Xerinae, the relationship of (Tamias sibiricus + (Callospermophilus lateralis + (Marmota himalayana + (Urocitellus richardsonii + (Ictidomys tridecemlineatus + (Cynomys leucurus + Cynomys ludovicianus)))))) is well supported. However, Tamiops swinhoei (Xerinae) within the subfamily Callosciurinae is a clade sister to Dremomys rufigenis (Callosciurinae). Spermophilus dauricus (Xerinae) within subfamily Sciurinae is a sister clade to Sciurus vulgaris (Sciurinae). The monophyly of Xerinae is failed to support in this study.
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.
