Table corals form table-like structures and often have fused branches. Elkhorn coral has large, flattened branches. Foliose corals have broad plate-like portions rising in whorl-like patterns. Encrusting corals grow as a thin layer against a substrate. Massive corals are ball-shaped or boulder-like and may be as small as an egg or as large as a ...

2024年11月13日 · The majority of corals are found across the Indo-Pacific. The global assessment of reef- building corals includes 85 Atlantic coral species highlighted in a PLOS One journal article also published today. Atlantic coral species are particularly highly threatened due to annual severe bleaching events, pollution and the impacts of disease.

Bleaching is the process by which corals lose their symbiotic algae, Zooxanthellae, that give them their distinctive colours and main energy sources, due to environmental stressors. Thus a bleached coral appears pale or white, and are more susceptible to disease and death. But bleached corals are not dead corals and can recover.

2025年1月14日 · New 5-km Coral Bleaching Products - Higher spatial resolution is the improvement to NOAA Coral Reef Watch remote-sensing products most requested by coral reef ecosystem scientists and resource managers. NOAA Coral Reef Watch and its partners have developed a new experimental daily global 5 km coral bleaching thermal stress monitoring …

Among the largest threats to corals are siltation and eutrophication, caused by deforesta-tion and sewage and fertilizer runoff. Eutrophication leads to increased growth of turf- and macroalgae, which compete with corals for space, shade smaller colonies and bind sedi-ment, which can lead to suffocation of corals.

Coral reefs are often called the rainforests of the sea, both due to the vast amount of species they harbour, and to the high productivity they yield.

The Coral Restoration Database is now being hosted on the ICRI Forum it was previously hosted by the team at James Cook University who developed the Database after synthesising the available knowledge of coral restoration methods in a review paper (published January 2020), incorporating data from the peer-reviewed scientific literature, complemented with grey …

have negative effects on corals and other marine organisms under certain circumstances. The chemical UV filter oxybenzone has been studied most intensively and the following effects have been described: • Bleaching of coral fragments and coral cells from various species of hard coral. This effect is more pronounced at higher water temperatures.
