  "searched": "Read the counted Nature Communications passage and checked time range, population, denominator, baseline, sampling, jurisdiction, and translation. The passage specifies a synthesis of 4,748 sites within 129 studies spanning terrestrial, freshwater, and marine ecosystems; the target result is specifically the marine and terrestrial subset, so I recorded that scope as a qualifier."
