What does this research mean for the field?

Female urinary 17β-oestradiol levels exhibit marked seasonality and influence male orientation behavior through chemical cues, though they do not act as a standalone determinant of mate choice in salamanders. Novelty: ClaimNovelty.NOVEL_FINDING. Consensus alignment: ConsensusAlignment.SUPPORTS_CONSENSUS.

Behavioral and endocrine study reveals urinary oestradiol influences male attraction in salamanders, indicating chemical cues guide orientation rather than definitive mate choice.

Key Points

To quantify seasonal urinary 17β-oestradiol dynamics in female Salamandrina perspicillata and assess whether female endocrine cues influence male orientation and mate choice.
Quantified female urinary 17β-oestradiol (E2) concentrations across the reproductive cycle using non-invasive urine sampling.
Assessed male behavioral responses across two Y-maze experiments: an orientation assay comparing female odor against a control, and a forced-choice assay between two females with differing E2 levels.
Female urinary E2 concentrations exhibited marked seasonality, peaking in late winter during vitellogenesis prior to oviposition.
Males oriented toward female chemical cues more frequently when female E2 levels were lower in the single-cue orientation assay.
Males demonstrated no significant preference between females with high versus low E2 levels in the forced-choice assay.
