Flight and hearing: ultrasound sensitivity differs between flight-capable and flight-incapable morphs of a wing-dimorphic cricket species
Bibliographic record
Abstract
We studied frequency sensitivity of flight-capable and flight-incapable forms of the wing-dimorphic cricket Gryllus texensis, using both behavioral and neurophysiological measurements. Behavioral thresholds for negative phonotaxis in response to ultrasound stimuli are lower for long-winged (i.e. flight-capable) crickets than for short-winged (flight-incapable) individuals, whereas thresholds for positive phonotaxis in response to a calling-song model do not differ. Similarly, thresholds of the identified interneurons ON1 and AN2 differ between flight morphs for high sound frequencies but not for the frequency of calling song. Our results show that sensitivity to ultrasound is closely linked to flight ability, and thus to the risk of predation from aerially hawking bats. We suggest that sensitivity to ultrasound is one of a suite of flight-associated characteristics, the development of which may be under common hormonal regulation.

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.
