No paper matched ozone doses across lab and outdoor reproduction records in a 2024 invertebrate data release

We audited support for lab and outdoor comparisons in 61 ozone reproduction records from 17 papers. Two papers had both settings and a match on insect species, measure, life stage and host species. Neither matched control and elevated ozone concentrations. The closest recorded dose pairs needed tolerances of 13 and 30 ppb. Thus a 10 ppb tolerance also gave no match. US and European samples in two publication periods had no dose-matched comparison. The later US sample had no reproduction records. Three unmatched log response contrasts were negative, but they do not separate setting from dose or protocol. Removing two ambiguous outcome labels left the matches unchanged. These are exact support counts for one extract, not causal effects or proof that lab results cannot apply outdoors. Publication bias, source labels, few papers and missing weather limit use. Code, aggregate evidence, source hashes, a figure and an independent parser check are included. Climate interactions were not tested.
