Why table corals matter in reef regeneration

Remember those large table corals (tabular Acropora) at the Great Barrier Reef?

A new study had shown them to be “extraordinary ecosystem engineers”, with the ability to regenerate coral reef habitats at the iconic reef at a rate 14 times higher—more than 20 years faster—than any other coral type.

In essence, the research indicated that overall reef recovery would slow significantly if these corals declined or disappeared at the reef.

Humpback whale breaching

Humpback whale numbers soar off Australia

After hitting a low of 300 individuals 30 years, humpback whale numbers off Australia’s east coast are soaring. Researchers from Australia’s Organization for the Rescue and Research of Cetaceans (ORRCA) are hoping for an increase in whale migration numbers this year. Census results from the past 21 years indicate an annual 10-15 per cent increase in whale migration numbers.

The crown-of-thorns starfish can sometimes be hard to spot using traditional survey methods.

New test to detect crown-of-thorns starfish

Outbreaks of crown-of-thorns starfish (CoTS) are bad news for coral reefs, so it is essential that they are detected and dealt with as soon as possible.

But detecting an outbreak in its early stages is not easy. What’s more, they sometimes hide under coral plates, while the younger ones can be as small as just a few millimetres.

To counter this, the researchers at the Australian Institute of Marine Science (AIMS) developed a new test to detect the presence of the starfish on coral reefs.

Migrating humpback whales have poor health on return journey

Every summer, East Australian humpback whales migrate from the feeding grounds in Antarctica to their breeding grounds in the Great Barrier Reef. They remain there for about several months, before making their way around the southern Australian coast back to Antarctica for the winter.
