The physiological effects of social status in the cooperatively breeding cichlid <i>Neolamprologus pulcher</i>
Bibliographic record
Abstract
The physiological effects of social rank were examined in three different experiments with Neolamprologus pulcher a cooperatively breeding cichlid, endemic to Lake Tanganyika, East Africa. The effects of rank on physiology between pairs of dominant and subordinate size‐matched fish (experiment 1) and among groups of four size‐matched fish (experiment 2) were examined. A third experiment mimicked the natural social structure in the wild; pairs were observed with other group members including breeders. The effect of social position was investigated on growth rates, liver concentrations of adenosine triphospate (ATP), lipids, proteins, creatine phosphate (CrP), glucose and glycogen as well as plasma cortisol. In naturalistic group settings, dominants displayed higher levels of liver protein and plasma cortisol. In the absence of breeders, dominant individuals (of helper pairs) had higher liver glycogen levels and dominant fish (held in groups of four) grew most. These results support previous cooperatively breeding mammal studies and suggest that dominant individuals experience higher cortisol levels as well as higher growth rates.

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.
