Strong Links Between Corals Reefs Key to Preserving Fish and Marine Resources

An international scientific team has shown that strong links between the corals reefs of the south China sea, West Pacific and Coral Triangle hold the key to preserving fish and marine resources in the Asia-Pacific region. Research by Dr Johnathan Kool of the ARC Centre of Excellence for Coral Reef Studies and James Cook University, and his colleagues, has established that the richest marine region on Earth — the Coral Triangle between...

Great Barrier Reef Dissolved by Sea Cucumbers?

Coral reefs are extremely diverse ecosystems that support enormous biodiversity. But they are at risk. Carbon dioxide emissions are acidifying the ocean, threatening reefs and other marine organisms. New research led by Carnegie’s Kenneth Schneider analyzed the role of sea cucumbers in portions of the Great Barrier Reef and determined that their dietary process of dissolving calcium carbonate (CaCO3) from the surrounding reef accounts for...

Deep-Reef Coral Prefers the Shade, Hates the Light

Coral reefs are among the most diverse ecosystems on the planet, second only to tropical rain forests. Bird’s nest coral (Seriatopora hystrix) is common throughout the Indo-Pacific and is able to live across a range of depths. However, there is little gene flow between the coral populations at each depth and even the algal endosymbionts (Symbiodinium), which provide energy for the corals to survive, are genetically different across...

Nature by Numbers

This beautiful video below shows how the Golden Ratio exists and appears in nature, from the shell of a Nautilus to the shape of a sunflower. Not only can you keep it in the back of your mind when diving or watching a Trochus snail cleaning you front pane, but also when designing and creating an aquascape for your tank, and arranging corals. Because the Golden Ratio is appearing everywhere in nature, using it to design and create an Aquascape...

Reefs have been Successful in Surviving Large Environmental Disturbances

Fossil corals, up to half a million years old, are providing fresh hope that coral reefs may be able to withstand the huge stresses imposed on them by today’s human activity. Reef ecosystems were able to persist through massive environmental changes imposed by sharply falling sea levels during previous ice ages, an international scientific team has found. This provides new hope for their capacity to endure the increasing human ...

Warmer Seas may Prevent Coral Reefs from Producing Clouds

Five years ago Graham Jones and his team at Southern Cross University in Lismore, New South Wales, Australia, demonstrated that algae living in coral tissue produce a gas called dimethyl sulphide (DMS). When released into the atmosphere, DMS helps clouds form over coral reefs. Jones says that the clouds block sunlight and cool the sea. His team have now discovered that a rise in ocean temperature of only 2 °C causes some algae to stop ...
