What the study actually shows

The 2026 field study monitored two chambers for 136 recording days and divided observations into P1–P4. A. flavicollis remained predominantly nocturnal and initiated all reported interspecific agonistic encounters; A. agrarius shifted away from nocturnal activity in P2 and P4. In those periods, it visited significantly fewer clock-hours during which A. flavicollis was active: P2, p=0.019; P4, p=0.033.Reported P1–P4 activity results

Why the proposed coordinate claim is unresolved

“Minutes after civil dusk” requires each visit to be transformed as visit time − that day’s civil-dusk time, followed by a comparison of the two species’ activity distributions across P1–P4. The supplied results provide civil-twilight definitions and supplementary dawn/dusk times, but not the required event-level transformed data, effect estimates, confidence intervals, or a model testing clock time against photoperiod-relative time. Thus, the evidence supports temporal niche segregation, not specifically a dusk-anchored rule.

Best-supported conclusion

Confidence: moderate that avoidance occurred in P2 and P4; low that it was coordinated by minutes after dusk. Seasonal changes are relevant: mean daytime length increased from 650.1 minutes in P3 to 813.4 minutes in P4, while maximum temperature increased from 3.1°C to 8.4°C, so fixed clock-hour comparisons could be confounded by changing light and temperature. However, the study’s single peri-urban site, two chambers, observational design, and approximately 15 interspecific encounters limit causal and general conclusions.

A stronger test would compare competing models using the complete timestamped data: fixed clock time, minutes after dusk, minutes before dawn, and light intensity, with period, temperature, chamber, and individual identity accounted for.
