Most Caribbean coral reefs may disappear within 20 years, if something isn’t done, a new report warns – but for once global warming is not to blame.
Warming seas around the world are threatening corals. But scientists from the Hebrew University of Jerusalem and Bar-Ilan University have noticed that corals in Eilat, at the North of the Red Sea, remain healthy even when exposed to higher temperatures. They suggest that the area could be a unique refuge for coral reefs in the […]
Scientists have learned that coral’s symbiotic algae can scoop up available nitrogen, store the excess in crystal form and slowly feed it to the coral as needed. Although it has been known for years that the algae serve nitrogen to their coral hosts, it was not known that they could store the nitrogen for later. […]
Researchers solve some of pulsating soft coral (Xenid) mysteries, but their siestas still unanswered.
How do corals evolve into separate species when their larvae can drift around the ocean over extremely long distances?
Corals in the genus Acropora generate much of the structural complexity upon which coral reefs depend, but they are susceptible to damage from toxic seaweeds. Acropora nasuta minimises this damage by chemically calling goby fishes who within minutes start chomping on the seaweed.
Proposed marine protected areas will cover just 30% of the UK’s deep sea coral reefs and 3% of the sponge fields, according to the first-ever set of maps detailing where vulnerable deep-sea habitats are likely to be found in the North East Atlantic.
Jobs, ecotourism and diving industries can benefit from having a diverse supply of weed-eating fish on the world’s coral reefs, scientists say. Despite their small size, relative to the sharks and whales that often get more attention, herbivorous fish play a vital role in maintaining the health of coral reefs, which support the livelihoods of 500 million people worldwide, according to a study published this month in the journal Ecology.
Nearly one-third of CO2 emissions due to human activities enters the world’s oceans, making them less alkaline and affecting calcification of corals. By the middle of the century, corals at the Northern edges of the tropics will be in trouble with the Hawaiian island reefs will be among the first to feel the impact.
Scientists have long believed soft corals, one of the many endangered elements of marine life, are only minor contributors to the structure of coral reefs. But that’s not true, says new research from Tel Aviv University. A new in-depth analysis of reefs in the South China Sea has revealed that massive parts of the reefs […]
