The Effects of the Operational Sex Ratio on Female and Male Mate Choice in the Jamaican Field Cricket (Gryllus assimillis)
Bibliographic record
Abstract
The operational sex ratio (OSR; ratio of sexually available females to sexually available males) is a social environment that greatly influences mate choice, but how it concurrently affects mate choice in both sexes in species with mutual mate choice remains poorly understood.In this thesis, I experimentally investigated the potential influence of variation in the OSR (male-biased, even sex ratio, and female-biased) on which sex is the choosiest in the Jamaican field cricket, Gryllus assimilis.I also tested the consistency of individual mate choice as quantified using a dichotomous mate choice test and a full-interaction choice test under different OSR levels.OSR did not influence female or male mate choice, but it did influence how potential mates interact.Females and males did not consistently choose the same mate between the two types of mate choices tests, and OSR did not affect the likelihood of consistently choosing the same mate.

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.
