The effects of increased flow rates on linear dominance hierarchies and physiological function in brown trout, <i>Salmo trutta</i>
Bibliographic record
Abstract
The formation of dominance hierarchies within groups of salmonid fish is well documented and stream tanks are often used to create environmentally relevant conditions in which to study this aspect of fish behaviour. Although stream tanks simulate the natural environment of the fish in many ways, they have limitations in that they provide the fish with a rather predictable and constant habitat. The present study illustrates that under these constant conditions, the behaviour of fish in their natural environment may not be truly represented. Under constant conditions hierarchies were formed among groups of four brown trout, Salmo trutta, and the dominant fish displayed physiological advantages. However, when an environmental perturbation of increased water flow, simulating a spate, was imposed, the social behaviour of the fish was altered and the physiological advantages of dominance were lost. Clearly, environmental changes affect the behaviour, and consequently the physiology, of salmonid fish, therefore the importance of taking environmental disturbances into consideration in studies of salmonid behaviour should not be underestimated.

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.
