Abstract

fetched live from OpenAlex

Diversification of threespine stickleback trophic morphology in relation to habitat has been studied extensively, but dentition has been ignored. Using samples of threespine stickleback from a range of habitats in the Pacific and Atlantic Basins, we characterize the morphology of individual teeth and their arrangement on the premaxilla. Although tooth morphology does not vary conspicuously, we observed striking differences in tooth arrangement between Pacific and Atlantic populations, significant variation among populations within basins, and pronounced sexual dimorphism in tooth number and arrangement within all populations from both basins.

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.

Teacher imitation

Not 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.
