Thermally tolerant corals have different mechanisms for responding to heat stress. This is the conclusion of a current study by an international team of researchers including the Konstanz biologist Professor Christian Voolstra that was published in Molecular Ecology. The team examined responses to heat stress in the smooth cauliflower coral (Stylophora pistillata) in the Red Sea by combining the Coral Bleaching Automated Stress System (CBASS) – a mobile rapid heat stress test—with molecular analyses, in order to identify different types of thermal tolerance. The procedure is to be used worldwide, and the respective results could help provide corals with more targeted protection from the effects of climate change.
