Cold Water Coral Fusion Documented for First Time

For the first time ever researchers from Scotland and Germany have documented fusion of coral skeletons in cold water coral known as Lophelia pertusa. “Normally it is very hard to see where one coral ends and another begins. But on our dives with JAGO, we were able to find reefs where orange and white types of the coral fused together,” says Dr. Sebastian Hennige of the Heriot-Watt University Edinburgh. “Coming from a tropical coral research background, seeing coral fusing like this instantly grabbed my attention, so we were able to successfully sample some corals for genetic and skeletal tests to prove that fusion happens between different individuals,” added Dr. Hennige. 141030102852 large Cold Water Coral Fusion Documented for First TimeThrough analysis the team was able to determine that this particular type of coral can recognize itself on a species level, fusing together to form the reef, as opposed to batteling for territory like their tropical counterparts. The response of fusion is counterintuitive to what researchers know about tropical species of coral that behave much more aggressively towards invading colonies. “Cold-water corals build their reefs in the dark and are not supported like this. But they seem to have found another way to attain stability,” explains Dr. Armin Form, a marine biologist at GEOMAR and co-author of the paper. “Either the corals actually fuse and form a joint stock, or a branch grows over another one without interference.” Dr. Form: “Given this plasticity [of Lophelia pertusa], we hope that the coral will be able to cope with future climate changes. But we are not sure if they can keep track with the rapid environmental changes we are already experiencing.” Read more here!More:

Reef Building Corals Responding to Acidification

An international team led by the James Cook University CoralCoE has provided some promising news for corals dealing with rising levels of acidification. “Our aim was to explore the effect of a more acidic ocean on every gene in the coral genome,” adds lead author Dr Aurelie Moya, a molecular ecologist with the ARC Centre of Excellence for Coral Reef Studies at James Cook. Staghorn corals are known to be the number one reef building species of reefs worldwide and researchers gathered fragments of wild colonies collected from the Great Barrier Reef of Australia and subjected them to elevated levels of Co2 in the lab.141203111222 large Reef Building Corals Responding to Acidification  “We found that, whereas 3 days of exposure to high CO2 disrupts formation of the coral skeleton, within nine days the baby corals had re-adjusted their gene expression to pre-exposure levels. Longer exposure seems to be less detrimental to coral health than we had assumed based on shorter-term studies,” states Dr Aurelie Moya, a molecular ecologist with the ARC Centre of Excellence for Coral Reef Studies at James Cook. “We saw that within a few days juvenile coral adapted to CO2 levels double those experienced today with no obvious disruption to its life processes,” adds study co-author, Professor David Miller, who heads up the molecular biology group at CoralCoE.

One Coral May Benefit from Climate Change

In another positive spin on climate change, researchers from North­eastern University’s Marine Sci­ence Center and the Uni­ver­sity of North Car­olina at Chapel Hill have discovered one species of coral that can actually benefit from a rise in ocean acidification. The amount of change that would typ­i­cally occur in about 10 mil­lion years is being con­densed into a 300-​​year period,” Co-author and associate professor at Northeastern Justin Ries says. “It’s not the just the mag­ni­tude of the change that mat­ters to the organ­isms, but how quickly it is occurring.” siderastrea siderea01 One Coral May Benefit from Climate Change Sideras­trea siderea courtesy of coralpedia.bio.warwick.ac.ukThe study showed that this species of coral (Sideras­trea siderea) exhib­ited a peaked or par­a­bolic response to both warming and acid­i­fi­ca­tion, that is, mod­erate acid­i­fi­ca­tion and warming actu­ally enhanced coral cal­ci­fi­ca­tion, with only extreme warming and acid­i­fi­ca­tion neg­a­tively impacting the corals. This was sur­prising given that most studies have shown that corals exhibit a more neg­a­tive response to even mod­erate acidification. Ries added. Acid­i­fi­ca­tion of the sur­rounding sea­water is cer­tainly impor­tant for marine organ­isms, but what is equally as impor­tant — per­haps even more impor­tant — is how the chem­istry of their internal cal­ci­fying fluid responds to these changes in sea­water chem­istry.” Read more here!More:

Blue Light Photos, Great Star Coral Polyps

Good morning all, it’s Black Friday!! I have been so busy this week with Holiday parties, work and cycling that my poor daily blog is just not getting done! I have a crazy beautiful colony of Great Star Coral, Montastraea cavernosa that we photographed the other night with our alien looking blue-lights. Shooting “OPEN POLYPS” like you see above has turned out to be a real challenge! Why you ask, go ahead ask why!!

CT Coral Scans Highlight Ocean Acidification

Research from the Hawaii Institute of Marine Biology (HIMB), based at the University of Hawaii at Mānoa (UHM), has highlighted another damaging effect of rising ocean acidity. “It was surprising to discover that small-scale changes in the environment can influence ecosystem-level reef processes,” said Nyssa Silbiger, lead author of the study and doctoral candidate at HIMB. “We saw changes in pH on the order of meters and those small pH changes drove the patterns in reef accretion-erosion.” The noted increase in erosion has scientists battling two fronts in the understanding of the accretion vs erosion balance of reefs.

Orange Fungia Plate Coral Timelapse Feeding

This is a quick time-lapse of a beautiful orange plate coral I took footage of at Aquatic Experience in Chicago. It was Midwest Coral Connection’s coral at their booth and was fed with BENOFISHAL fish food. Overall this fungia loved the food and even though the video didn’t come out perfect, it is still pretty cool.

Neptunes Cove Boasts Rainbow Carpet Nem

RainbowCarpetAnemone14b1 Neptunes Cove Boasts Rainbow Carpet Nem
Lately we have seen a surge in our hobby through avenues such as facebook and instagram. Communities within mediums like facebook are growing, and pages are created with their own regional attachments and colorful groups of people. Instagram is showcasing the latest and greatest coral imported through an instant feed, and the days of sifting through page after page to view comments or pictures are quickly disappearing. Everyday it seems the newest, biggest and baddest, coral hits the market and its no wonder why vendors are gravitating towards these mediums. With that said Im going to my best to bring you the latest and greatest in the “For Sale” worlds slowly being crafted here on the internet. For our first showcase were featuring a “Rainbow Carpet Anemone” from the retailer Neptune’s Cove. This thing is one of the most righteous nems ever imported and I can only imagine how it gleamed in person. Enjoy the eye candy because this beautiful specimen sold promptly for $1600 shipped.… More:
