University of Guam Marine Lab associate professor, Alexander Kerr, is senior author of a paper on the evolutionary origins of coral sex published in the Proceedings of the Royal Society B. The paper, "Correlated evolution of sex and reproductive mode in corals" finds that ancient corals consisted of mostly separate sexes and needed to pass through an evolutionarily period in which they brooded their young before they could become spawning hermaphrodites. "Most species of corals on tropical...

An Australian scientist has discovered what could be the world's rarest coral in the remote North Pacific Ocean. The unique Pacific elkhorn coral was found while conducting underwater surveys of Arno atoll in the Marshall Islands, by coral researcher Dr Zoe Richards of the ARC Centre of Excellence for Coral Reef Studies (CoECRS). The coral bears a close physical resemblance to the critically endangered and fast-vanishing elkhorn coral (Acropora palmata) of the Atlantic Ocean, but genetic...

Scientists say that a species of coral in the Red Sea could stop growing by 2070 if current warming trends continue. A team of researchers said they used 3D technology to find that the rate of growth of Diploastrea heliopara declined by 30 percent since 1998. They found that rising sea surface temperatures were already "driving dramatic changes" in the growth rate of the important reef-building organism. Co-author Anne Cohen, a research specialist at Woods Hole Oceanographic Institution...

Concrete evidence found Improving the quality of local water increases the resistance of coral reefs to global climate change, according to a study published in June in Marine Ecology Progress Series. Florida Institute of Technology coral reef ecologist Robert van Woesik and his student Dan Wagner led the study, which provides concrete evidence for a link between environmental health and the prospects for reefs in a rapidly changing world. Van Woesik and his team showed that when waters in...

International law failing to protect coral reefs and tropical fish International law has failed to protect coral reefs and tropical fish from being decimated by a growing collectors market, but U.S. reforms can lead the way towards making the trade more responsible, ecologically sustainable and humane. That's the view of 18 experts, including Washington State University marine ecologist Brian Tissot, writing in the journal Marine Policy. "Our actions have a big impact on what happens in these...

Biologist Mikhail Matz uses next-generation sequencers and a massive, NSF-supported supercomputer to study corals at the genomic level and look for evolutionary changes Our oceans are getting warmer and more acidic every year; as a result, coral reefs are rapidly declining. Biologist Mikhail Matz is monitoring this process at the genomic level, in anticipation of evolutionary developments that may signal better news. "Corals have a substantial potential to evolve, and this is the high time...

Discoveries about tropical coral reefs, published on June 23, 2010, are expected to be invaluable in efforts to restore the corals, which are succumbing to bleaching and other diseases at an unprecedented rate as ocean temperatures rise worldwide. The research gives new insights into how the scientists can help to preserve or restore the coral reefs that protect coastlines, foster tourism, and nurture many species of fish. The research, published in the journal PLoS One, was accomplished by...

Corals right out on the exposed edges of the world's great coral reef zones may hold an important clue to the survival of coral ecosystems facing intensifying pressure from human activities and climate change. In a paper in the international journal Science, researchers Professor John Pandolfi of the ARC Centre of Excellence for Coral Reef Studies and University of Queensland and Professor Ann Budd of the University of Iowa have released new evidence showing that the evolutionary action on...

Evolutionary potential, edge zones, should be considered as factors Conservation efforts aimed at protecting endangered Caribbean corals may be overlooking regions where corals are best equipped to evolve in response to global warming and other climate challenges. That's the take-home message of a paper published in this week's issue of the journal Science by researchers Ann Budd of the University of Iowa and John Pandolfi of the University of Queensland, Australia. Budd and Pandolfi focus on...

Researchers at the University of Gothenburg have discovered a new sea anemone that is thought to have established itself in Swedish waters. Larvae from similar anemones cause skin problems for sea bathers in the USA. Researchers at the Department of Marine Ecology at the University of Gothenburg have been following the invasion of the American comb jellyfish, Mnemiopsis, for several years. They have now discovered that it contains larvae from another species: a sea anemone that lives on it as...

Knotted Fan Coral, (Melithaea ochracea), is a species of colonial soft coral that is found in tree-like fans on shallow reefs in the South China Sea between Taiwan and Indonesia, including Singapore and Malaysia. In Taiwan, it is the most widespread coral in its family Gorgonacea. It is found on the higher parts of reef fronts where its numerous small polyps can feed at water flow rates varying from 1.6 to 16 inches per second. This species usually grow to about 8 inches in length, with...

Octopus Coral, (Galaxea fascicularis), also known as Fluorescence Grass Coral, Galaxy Coral. Star Coral, Crystal Coral, Brittle Coral and Starburst Coral, is a species of colonial stony coral commonly found on reef slopes in the Indian and Pacific ocean regions, as well as the Red Sea and the Gulf of Aden. It is most commonly found where wave action is weak, usually at a depth of 79 inches to 49 feet below sea level. It is a common coral species among reef aquarium enthusiasts. This coral...

Chalice Corals, are a family of stony corals in the Pectiniidae family. Members of this family are mostly colonial but at least one species, Echinomorpha nishihirai, is solitary. These corals are endemic to the Indian and Pacific oceans. Pectiniids have a number of different forms but are basically streamlined and smooth. Polyps are large and brightly colored and resemble those of members of the Mussidae family of corals. The polyps are only extended at night. Tentacles are translucent,...

Siderastreidae is a family of colonial, reef building stony corals. Members of this family include symbiotic algae in their tissues which help provide their energy requirements. The World Register of Marine Species lists 7 genera within this family: Anomastraea, Coscinaraea, Craterastrea, Horastrea, Psammocora, Pseudosiderastrea, and Siderastrea. Corals in this family vary in form and include massive, thickly encrusting, columnar, and irregular forms. Corallites are linked by flowing...

Leaf Plate Montipora, (Montipora capricornis), also known as Vase Coral, Cap Coral, or simply Montipora, is a species of stony coral found in the Indian and Pacific oceans. It is also found in reefs in the Red Sea. It usually inhabits the top half of the reef where photosynthesis can occur. It branches out from the foundation into an area with adequate sunlight. This species forms flat, plating colonies. The colonies expand by adding to their foundations and further spreading out....
