Time from injection of luteinizing hormone‐releasing hormone analog affects sperm quality in the critically endangered Mississippi gopher frog (<i>Lithobates sevosus</i>)
Bibliographic record
Abstract
The objective of this study was to investigate variation in sperm quality metrics (motility, velocity, and concentration) in the critically endangered Mississippi gopher frog (Lithobates sevosus) over three sampling time points after a luteinizing hormone-releasing hormone analog (LHRHa) induction injection. Sperm was repeatedly collected from 11 individuals over three sampling times (30, 60, and 120 min) after injection. Variation in sperm quality was investigated using a repeated-measures mixed model approach. Repeated measures analyses of variance showed a significant effect of sampling time for percent motility and velocity. Concentration was found to be marginally related to sampling time, while progressive motility was not significantly related to time after injection. Our findings are important for optimizing assisted reproduction-related fertilization success and increasing the successful propagation of endangered species of imperiled frogs in captive breeding programs.

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.
