Abstract

fetched live from OpenAlex

AbstractNorthern gannets Sula bassanus consume thousands of tons of pelagic prey in Newfoundland waters. To evaluate the hypothesis that harvests by seabirds and humans are similarly influenced by local fluctuations in prey availability, the annual catches of mackerel Scomber scombrus and squid Illex illecebrosus by gannets and humans over a 10-year period off northeastern Newfoundland were compared. Comparisons of annual fluctuations in the percentage by mass of different prey in the food loads of gannets with commercial fishery landings in nearby bays indicated that extreme reductions of dominant prey in the birds' diet were directly associated with subsequent local pelagic fishery failures. Dietary data collected from marine birds also provided information about the availability of prey that are neither commercially fished nor systematically surveyed.

Full frame distilled prediction

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.
