Condition-dependent behaviour among damselfly populations
Bibliographic record
Abstract
Body condition is predicted to influence behaviours such as activity, which in turn affects energy gain and survival. In this study we investigated (i) whether populations of the damselfly Lestes sponsa (Hansemann, 1823) differ in body condition and activity among lakes, and (ii) which body condition factors affect behaviour. We estimated last instar larval behaviour (measured as activity), body condition (measured as size, body mass, muscle mass, fat content, and time to emergence), and fish presence/absence in eight lakes. Body condition of larvae differed among lakes but the presence/absence of fish in lakes had no effect on body condition. Activity did not differ among lakes and was not affected by the presence/absence of fish in lakes. Activity was negatively related to size, body mass, muscle mass, and fat content, and positively related with time to emergence, suggesting that final-instar larvae in good condition are favouring development over growth to emerge earlier. This study highlights the importance of differences in condition among populations and among individuals.

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.
