Sediment; Not That Bad for Coral Reefs After All?

Sediment; Not That Bad for Coral Reefs After All?

Rapid rates of coral reef growth have been identified in sediment-laden marine environments, conditions previously believed to be detrimental to reef growth. A new study has established that Middle Reef — part of Australia’s iconic Great Barrier Reef — has grown more rapidly than many other reefs in areas with lower levels of sediment stress. Rapid rates of coral reef growth have been identified in sediment-laden marine...

Coral Bleaching Maybe Caused by Viruses

Coral Bleaching Maybe Caused by Viruses

Scientists have discovered two viruses that appear to infect the single-celled micro algae that reside in corals and are important for coral growth and health, and they say the viruses could play a role in the serious decline of coral ecosystems around the world. These viruses, including an RNA virus never before isolated from a coral, have been shown for the first time to clearly be associated with these micro algae called Symbiodinium. If...

How to Prepare your Reef Tank for the Holidays

How to Prepare your Reef Tank for the Holidays

It’s a fact that all aquarists, sooner or later, take a holiday. But our Reef tanks stay home, waiting for us to return. As Murphy’s Law teaches, if something can go wrong, it will do so in the  worst time and in the worst way. And with many years of experience I can say that I’ve seen that everything can happen. To avoid unpleasant surprises, we have to be prepared for the worse, because it can happen. So let us analyze the problem from...

Corals Hosting a Single Type of Zooxanthellae can have Different Levels of Thermal Tolerance

Corals Hosting a Single Type of Zooxanthellae can have Different Levels of Thermal Tolerance

Recent experiments conducted at the Australian Institute of Marine Science (AIMS) produced striking results, showing for the first time that corals hosting a single type of zooxanthellae can have different levels of thermal tolerance – a feature that was only known previously for corals with a mix of zooxanthellae. Zooxanthellae are single-celled plants that live in the tissues of animals. They are dinoflagellates, a group of microscopic...

AEFW Treatment, How To Get Rid Of Them

AEFW Treatment, How To Get Rid Of Them

Now that I’m starting a new tank and introducing a lot of new Acropora colonies to my precious colonies, I will thing again how to prevent an AEFW outbreak, because it can be heartbreaking. I will also think about ways to control them in case just a few survive a quarantaine treatment and multiply over the next months and years. In this article I will explain how to deal with this pest, after learning from previous outbreaks and using the...

Semporna (Borneo, Malaysia) May Have the World’s Highest Marine Biodiversity

The preliminary results of the Semporna Marine Ecological Expedition (December 2010) indicate that Semporna may have the world’s highest marine biodiversity. The expedition yielded a record number of 43 species of mushroom corals. Furthermore, some new species were discovered, among which at least two shrimps and possibly a number of gall crabs. The health of the reefs was judged to be relatively poor: 36% of the transects had fair,...
