Phylogeny of members of the rockfish (<i>Sebastes</i>) subgenus<i>Pteropodus</i>and their relatives
Bibliographic record
Abstract
The Sebastes Cuvier, 1829 subgenus Pteropodus Eigenmann and Beeson, 1893 includes six species from the northeastern Pacific Ocean (NEP) and four species from the northwestern Pacific Ocean (NWP). Several NEP species assigned to other subgenera are similar to NEP Pteropodus species. Restriction site variation in the mitochondrial NADH dehydrogenase subunit 3 and 4 genes and the 12S and 16S ribosomal RNA genes were used to evaluate their relationships. Phylogenetic reconstruction showed that six NEP species of Pteropodus formed a monophyletic group that also included three NEP species currently assigned to other subgenera: Sebastes atrovirens (Jordan and Gilbert, 1880) (subgenus Mebarus Matsubara, 1943) and Sebastes auriculatus Girard, 1854 and Sebastes dalli (Eigenmann and Beeson, 1894) (both subgenus Auctospina (Eigenmann and Beeson, 1894)). The small average nucleotide divergence (0.0124 per nucleotide) observed among members of this group of species was similar to that observed among species of the monophyletic subgenus Sebastomus Gill, 1864 (0.0089 per nucleotide). The NWP species of Pteropodus did not cluster with their NEP consubgeners but, generally, were similar to other NWP species. We recommend that S. atrovirens, S. auriculatus, and S. dalli be included in subgenus Pteropodus with the other NEP species and that the NWP species of Pteropodus be removed from the subgenus. Our results indicate that the morphological characteristics used to distinguish species often may not be useful for phylogenetic analysis.

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.
