Abstract
Roscoe DW, Hinch SG, Cooke SJ, Patterson DA. Behaviour and thermal experience of adult sockeye salmon migrating through stratified lakes near spawning grounds: the roles of reproductive and energetic states. Ecology of Freshwater Fish 2010: 19: 51–62. © 2009 John Wiley & Sons A/S Abstract – Little is known about physiological factors underlying thermal behaviour in Pacific salmon ( Oncorhynchus spp.). We implanted acoustic transmitters and temperature loggers into migrating adult sockeye salmon ( Oncorhynchus nerka ) and nonlethally assessed their reproductive hormone levels and energetic states immediately prior to their passing through natal lakes en route to spawning grounds. We tested the hypothesis that energetic and reproductive status influence thermoregulatory and other in‐lake behaviours. More reproductively advanced females with lower levels of energy transited through cooler temperatures compared to less mature females with high levels of energy, possibly to reduce metabolic energy expenditure and delay final maturation. Transit temperatures of males were not related to physiological variables. Salmon travelled on average 13.6 km·day −1 through two lakes, and often circled or held for more than 1 day before moving upstream, but these behaviours were generally not related to physiological variables.

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 it
