Degree heating weeks fail to reach alert thresholds yet coral bleaching is widespread: structural insensitivity of anomaly-based metrics across Japan's latitudinal gradient

Hiroki Fukui

The paper shows that Degree Heating Weeks (DHW) underperform in predicting coral bleaching in Japan's latitudinal gradient, with a simpler temperature metric outperforming DHW in detecting bleaching.

Bimodal distribution of coral bleaching prevalence is consistent with state transition dynamics in thermal stress response: five years of standardised monitoring in Japan

Hiroki Fukui

The paper analyzes five years of coral bleaching data from Japan, finding a bimodal distribution and showing that ecological severity thresholds are inseparable from metric design.
