Using NOAA Satellite Data to Keep Watch on Coral Reefs Biology Diagrams It could also have knock-on effects between species and up the food chain, she added. Human-driven climate change has spurred mass coral bleaching as the world's oceans get warmer. Coral reefs provide shelter, spawning grounds, and protection from predators. They also support organisms at the base of ocean food chains. As reef ecosystems collapse, already at-risk species may face extinction. How does coral bleaching impact humans? Coral bleaching impacts peoples' livelihoods, food security, and safety.
Coral bleaching has a variety of causes. It may result from increases in seawater temperature, particularly when associated with elevated levels of solar irradiance (e.g., ultraviolet radiation), or it may be caused by changes in seawater chemistry (e.g., due to ocean acidification or pollution), increased levels of sediment in seawater, or a coral's exposure to sodium cyanide (a chemical

The Importance of Coral Reefs (image credits: pixabay) Coral reefs are vital to marine ecosystems, offering a habitat for a vast array of marine species. They serve as nurseries for fish, providing shelter and food. Coral reefs support over 25% of all marine life, despite covering less than 1% of the ocean floor.
Coral reef mesopredators switch prey, shortening food chains, in ... Biology Diagrams
The effects of this changing prey community on reef-associated mesopredators remains poorly understood. This study found that the total diversity, abundance and biomass of piscivorous mesopredators was lower on regime-shifted reefs than recovering reefs, 16 years after the 1998 mass coral bleaching event. Introduction. Coral bleaching is a global issue that threatens the persistence of coral reefs, the world's most diverse marine ecosystems , , .Over the past 15 years, several major bleaching events have occurred around the globe and caused widespread mortality of corals .Consequently, coral cover on reefs throughout the Indo-Pacific region is declining at a rate of approximately 3,100 km 2 per
