Coral death is impacting oceans worldwide as a consequence of climate change. The concern is that corals cannot keep pace with the rate of ocean warming. In particular, because a temperature increase of only one degree Celsius can make the difference between healthy and dying coral reefs. Some corals, however, are more resistant to increasing temperatures.
In order to effectively protect coral reef habitats, it is important to identify which corals and reef sites are more resistant and thus have a greater chance of survival. For this purpose, the research team led by Konstanz biologist Professor Christian Voolstra developed a rapid stress test to assess coral thermotolerance.
The “Coral Bleaching Automated Stress System” (CBASS) makes it possible to assess coral thermotolerance on site and within a single day – much faster than current experimental procedures that typically take several weeks to months in a laboratory. A description of the test and a demonstration of its utility to resolve thermotolerance differences between close-by reef sites was published as an online early article on 21 June 2020 in the journal Global Change Biology.
