Exploring the Relationship Between Physiological Performance and Reproductive Investment in Wild Fish Using Heart Rate Biologgers
Bibliographic record
Abstract
Given that reproductive behaviours involve high-energy activities, scientists have hypothesized that reproductive fitness is related to an organism's physiological performance. The present thesis explored this hypothesis by relating heart rate performance to parental care behaviour in smallmouth bass (Micropterus dolomieu), and dominance behaviour in sockeye salmon (Oncorhynchus nerka). The results did not detect a relationship between overall heart rate performance and reproductive behaviour in either species. Instead, heart rate was found to follow a diel pattern irrespective of behaviour. It is therefore proposed that reproductive behaviour is mediated by the combined effects of intrinsic (e.g. hormones, cardiac performance) and extrinsic (e.g. photoperiod, predator burden) factors. Hence, this thesis demonstrates the complex relationship between cardiac performance and reproductive behaviours in wild fish. Future studies are required to explore the relationship between physiological performance and reproductive fitness to better understand mechanisms driving animal life history and evolutionary ecology in changing environments.

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.
