Selective foraging in the white sucker (<i>Catostomus commersoni</i>)
Bibliographic record
Abstract
The white sucker (Catostomus commersoni) is a widespread and often abundant North American species. This benthivore can play an important role in the ecology of both fish and benthic communities in lakes and streams. However, the feeding behaviour and ecology of the white sucker have received limited study beyond a description of gut contents from small samples of fish. In this study, the diet of white suckers was determined in relation to season and depth distribution of the fish, as well as to the abundance and type of zoobenthos sampled at the site of fish capture. Suckers fed predominantly on either zoobenthos or zooplankton, with some seasonal variation. They specialized on particular prey and also on the largest individuals within their "speciality," thus exhibiting both resource partitioning and size-selective predation. These findings demonstrate that white suckers can be extremely flexible in their use of resources as opposed to being simple generalist feeders. This attribute, plus their tolerance of a range of environmental conditions, partly explains the abundance of white suckers and their wide distribution in temperate lakes and streams.

Full frame machine prediction
Teacher imitationNot 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.
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 source (direct Gemma or distilled Codex), not a consensus.
