Abstract

fetched live from OpenAlex

Genealogical relationships among Gasterosteidae (Teleostei: Gasterosteiformes) were tested with 84 morphological, 48 behavioral, and 2879 molecular characters. Phylogenetic analysis of the combined data set identified a single (CI = 0.735) best-supported hypothesis (Spinachia (Apeltes ((Pungitius + Culaea)(Gasterosteus aculeatus + G. wheatlandi)))). This hypothesis is identical to previous phylogenetic propositions proposed on the basis of behavioral, and behavioral plus morphological data. Our hypothesis, however, differed from a molecular-based phylogeny in the placement of Apeltes. This analysis highlights the importance of combining all available evidence in order to produce the best-supported proposition of genealogical relationships.

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.

Not 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.
