Diets of the Arkansas River Shiner and Peppered Chub in the Canadian River, New Mexico and Texas
Bibliographic record
Abstract
ABSTRACT We examined the digestive tract contents of 1,437 Arkansas River shiners (Notropis girardi) and 1,943 peppered chubs (Macrhybopsis tetranema) collected from the Canadian River in New Mexico and Texas from September 1996 to August 1998. Both the Arkansas River shiner and peppered chub are generalist feeders, with terrestrial and aquatic insects representing 28 and 31%, respectively, by weight, of their diets. Detritus, plant materials, and sand-silt represented 26, 6, and 40%, respectively, of the Arkansas River shiner diet and 25, 28, and 17% of the peppered chub diet. The presence of sand-silt in the diets of both species suggests they forage among sediments on the river bottom. The common occurrence of terrestrial insects (i.e., Coleoptera, Hymenoptera) in the diet of the Arkansas River shiner indicates this species also feeds in the water column on drifting invertebrates.

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.
