These reef-building corals may be at risk of extinction • Earth.com
Reef-building corals in the Red Sea may be at risk of extinction due to the way that spawning events have changed over time, according to a new study.
Broadcast spawning involves the release of both eggs and sperm into open water. But in recent years, spawning events of reef-building corals in the Red Sea are out of sync due to climate change and human activities, which has reduced fertilization success.
