Narrow thresholds of canopy disturbance determine the microclimate buffering potential of tropical forests
Bibliographic record
Abstract
The importance of protecting logged and recovering tropical forests has gained much attention. Disturbed forests can, however, have hotter microclimates, exacerbating the effects of future climate change. Using thermal imaging we captured understory surface temperatures along a gradient of tropical forest disturbance, and compared these to the upper thermal limits (CT max ) of invertebrates within the same forests. Surface temperatures exceeding the CT max of invertebrate groups occurred once canopy cover fell below 76%. In highly degraded forests, surface niche space was reduced by 22% for the most sensitive taxa, and this doubled following simulated warming of +3°C. In contrast, all invertebrate groups were buffered in sites that retained 80% canopy cover or higher even following severe warming. We demonstrate a narrow threshold of canopy disturbance beyond which microclimate buffering is significantly diminished. These findings illustrate the importance of conserving high canopy cover forests to protect tropical biodiversity in a hotter future.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
