Rising seawater heat may collapse coral oxygen flow before bleaching appears

Tropical coral reefs support the highest levels of biodiversity in the ocean. This vital ecosystem depends on reef-building corals, which form colonies of thousands of tiny coral animals that secrete calcium carbonate skeletons, ...

Genes without borders: Coral babies can travel vast distances across the Pacific Ocean

The offspring of a common coral branching species set up a new home up to 100 kilometers or more from their parents in one of the longest dispersal distances ever measured, according to new international research.

Nutrient imbalance may drive coral disease more than heat stress

Scientists led by the University of Southampton have revealed that an imbalance of nutrients in seawater can cause coral disease—possibly to a greater extent than that from heat stress of warming oceans. New research conducted ...

Massive reef expansion 20 million years ago may explain modern coral life's origins

New research published in Science Advances reveals that the largest expansion of coral reefs in the past 100 million years happened about 20 to 10 million years ago, between Australia and Southeast Asia.
