Abstract
ABSTRACT A 2024 paper in Science described the realised and potential thermal niches of 188 North American tree species in terms of mean annual temperature (MAT). Using PlantSearch data from outside species‐native distributions, it was found that species potential niches displayed a ‘centrifugal organisation’ of thermal niches. As a result, ‘potential niches of cold‐adapted species extend to warmer temperatures, whereas potential niches of warm‐adapted species extend to cooler temperatures’. These patterns could have important implications for tree species management under climate change, and the study described here aimed to determine if similar patterns could be found with the MAT niches of eucalypt species. The realised niches of 48 eucalypt species and subspecies were assessed in terms of MAT range using maps from a 2016 book and 2022 paper as well as the Atlas of Living Australia (ALA). Potential niches for 44 species and subspecies were examined using ex situ data from the PlantSearch database of Botanic Gardens Conservation International (BGCI). Results from the study described here were less clear‐cut than the North American study, but some similarities were found. For example, potential niches of cold‐adapted species extended to warmer temperatures, whereas potential niches of warm‐adapted species extended to cooler temperatures. In summary, there was some support for the conclusions of the North American study. However, data from arboreta and botanic gardens should be used with care or levels of species climatic tolerance may be exaggerated. The collation of data from commercial trials, which would be more representative of broadscale areas and could also include provenance as well as species information, is recommended.

Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
