No supplied record reports growing-degree-day sums, canopy closure values, anthesis status, or any 2026 observations from Gaina-Lucina or the three lower Bucovina bogs. The evidence records address berry phenolics (), microbiota, peroxidase biochemistry, rat models, and British Isles habitat preferences (montane heath at ~900 m; pH 3.5β5.8 soils) () β none directly relevant to a thermal-sum/anthesis comparison.
What is missing: site-level GDD base-5Β°C sums for all four bogs in 2026 and prior years, canopy measurement protocols, flowering phenology data, and controls for confounders (late frost, soil moisture, shrub age, prior-year resource status). The hypothesis is plausible but untestable with current evidence.
