Abstract
Acoustic communication is of fundamental importance in many fish species but it is often unclear what information is present in different calls and how responsiveness varies with reproductive state and the sex of the receiver. The current study investigates reproductive flexibility in acoustic responsiveness through differential attraction between reproductive morphs of the round goby ( Neogobius melanostomus ) to conspecific calls. Parental male (PM) round gobies emit calls and females respond to these calls with high specificity. We used playback experiments to determine the response of gobies to recordings of two conspecific calls, a grunt and a drum. For the grunt, reproductive females (RF) displayed a significantly higher response for first approach than non-reproductive males (NRM), but RFs never responded to the drum call. Upon examining within-morph responses for time spent at a playing speaker, RFs were found to spend the longest time at the grunt call compared to other sound types. In contrast to the female responses, NRMs and sneaker males (SM) displayed a strong preference to the drum call. Overall these results support that the grunt could be for mate attraction while NRMs and SMs may be eavesdropping on the drum call. By determining the relationship between reproductive state and responses to conspecific calls, we show that reproductive state is a critical factor in understanding behavioural responses in fish.

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 it
