Abstract

Coral reefs are one of the most biologically diverse ecosystems on the Earth. Besides their great ecological importance, they are also of considerable importance for human societies. In recent time, a lot has been written and told about threats for these marine ecosystems, especially about coral reef bleaching. The aim of this work is presentation of coral reef bleaching issues. Global climate change leads to increasing temperatures that are the main cause of more frequent and more severe mass coral bleaching events. During these events, corals eject algal symbionts of genus Symbiodinium (zooxanthellae) from their tissues and this leads to the breakdown of symbiosis. Corals typically experience high mortality during severe coral bleaching events. Besides corals and zooxanthellae, bleaching also affects a lot of other organisms that live on coral reefs. More frequent and more intense coral reef bleaching events are predicted in the coming decades. It is purely clear that coral bleaching will be a severe threat to continued coral survival for the next 30-50 years even under the most optimistic climate scenarios. Corals can respond to higher temperatures through adaption and acclimation. However, the critical question is whether corals can respond to higher temperature quickly enough to keep up with global warming.
