Abstract

fetched live from OpenAlex

The present paper analyzes the diet, feeding strategy and niche width of Bathyraja albomaculata over the Patagonian continental shelf and upper slope. The diet comprised a variety of 14 small invertebrates, although the most important prey were polychaete worms. The opheliid polychaete Travisia sp. and the gammarid amphipod Cirolana sp. were the main prey present in stomach contents of B. albomaculata. No differences were found between the diets of males and females, however ontogenetic changes were detected. Skates <40 cm of disk width (DW) preyed on amphipods, and sizes >40 cm DW largely consumed polychaetes. As size increased, polychaetes became more important and the importance of amphipods decreased. B. albomaculata showed a narrow food niche and a marked specialization towards polychaetes.

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.
