- Physiological responses of scleractinian coral to trace metal enrichment and thermal stress. Tu, Ting-Hsuan Hsieh, Hung-Yen Meng, Pei-Jie Chen, Chung-Chi Animals Anthozoa Water Pollutants, Chemical Photosynthesis Stress, Physiological Trace Elements Manganese Iron Climate Change Coral Bleaching Metals Coral bleaching events are increasingly frequent due to global climate change and marine pollution. Trace metals, such as manganese (Mn) and iron (Fe), though toxic at high concentrations, are vital for coral physiology, supporting photosynthesis and antioxidation. This study investigates how thermal stress and trace metal exposure interact to influence the physiology of the scleractinian corals Turbinaria irregularis and Montipora mollis. Corals were exposed to Mn and Fe at varying concentrations under control (25 °C) and elevated (30 °C) temperatures. Mn enhanced photosynthetic efficiency, an increase of 1.7°% in M. mollis at 250 nM and 1.4°% in T. irregularis at 30 °C (p
