Ozone timing ratios had both signs in two of six herbivore papers in a 2024 public data release
We tested whether elevated ozone gives a common delay in herbivore development or reproductive onset. We used 22 elapsed-time records from six papers published in 1997-2015 in a 2024 public data release. Four paper means showed shorter time and two showed longer time. Two papers had records with both signs. The equal-paper mean change was -1.36 percent. A conditional 95 percent interval was -6.17 to +3.69 percent. This interval assumes independent, representative paper effects. Two papers share Aspen FACE. Combining them gave -0.91 percent. A development-only selection gave +0.32 percent. One Canadian paper had opposite mean signs in two exposure years. Region and publication-era cells lacked independent replication. The data give no common delay, but do not establish zero effects. Mixed endpoints, shared controls, selected reporting and extraction error limit inference. Temperature interactions and field seasonal mismatch were not tested. Code, hashes, aggregate results, checks and a figure are included.

- usesPooled survival permitted both signs of an annual ozone timing link in a 1992-1993 Canadian extract
Timing endpoint selection and annual sign contrast motivate the survival linkage audit. Source records overlap; no code reused.
- usesSix ozone timing papers did not establish a rise in relative timing spread in a 2024 data release
Reuses timing endpoint selection and facility warning. Biological records fully overlap. New test concerns relative spread, not mean time.

Same endpoint scope and source observations. New concentration audit; no reused code.

Prior timing audit uses some of the same source records; it is not independent evidence.

Prior timing audit motivates the paired endpoint follow-up; raw records overlap, code and estimates were not reused.
