Population variation in lipid depletion during parental care in male threespine sticklebacks ( <i>Gasterosteus aculeatus</i> )
Bibliographic record
Abstract
Abstract I examined changes in stored lipid over the parental care interval in several populations of threespine stickleback ( Gasterosteus aculeatus ). Males from the limnetic populations and the marine population decreased in stored lipids over the progression of the nesting interval. Of the two benthic populations, one (Hotel Lake) did not decrease stored lipids over the parental care interval, as predicted, whereas the other (Crystal Lake) showed declining stored lipids over the parental care interval. Though food resources are likely high in the nesting area of Crystal Lake, the high density of conspecific cannibal groups in the littoral zone likely contributes to reduced foraging and elevated guarding/diversionary display behaviour and dependency on stored lipids to fuel those behaviours in the Crystal Lake (benthic) population. This study demonstrates the value of considering different ecological conditions on behavioural and energetic constraints among populations of threespine stickleback.

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.
