Heritability of acoustic signalling time in the Texas field cricket, Gryllus texensis
Bibliographic record
Abstract
Hypothesis: Heritability estimates of total nightly signalling time will be equal for a contemporary data set in Austin (Texas) and an earlier data set collected 127 km away in San Antonio (Texas). Organism: Texas field cricket, Gryllus texensis (Gryllidae: Orthoptera). Background: A corpus of work has been done on Gryllus texensis in Austin, Texas with the underlying assumption that heritability values from San Antonio, Texas apply. Methods: Previous study – realized heritability estimated using an artificial selection experiment. Current study – narrow sense heritability estimated using parent–offspring, full-sib/half-sib, and restricted maximum likelihood methods. Results: Heritability of total nightly signalling time was previously computed as 0.50 and 0.53 for the San Antonio crickets. However, heritability of total nightly signalling time in the Austin crickets is estimated at only 0.006 ± 0.045. In Austin, only a small portion (1.5 ± 11%) of the genetic variance in total signalling time is additive.

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.
