Uncovering the concealed daily life of ‘dead’ coral reefs – UQ Information

Uncovering the hidden life of ‘dead’ coral reefs - UQ News

‘Dead’ coral rubble can help much more animals than stay coral, according to University of Queensland researchers trialling a high-tech sampling approach.

UQ’s Dr Kenny Wolfe mentioned that reef rubble habitat was generally ignored as desolate, unattractive and ‘dead’, nevertheless reef rubble was really much alive.

“When individuals consider of coral reefs they usually think of greater invertebrates that are conveniently discovered, this sort of as sea cucumbers, starfish and large clams,” Dr Wolfe said.

“But curiously, lifeless coral rubble supports far more of what we contact ‘cryptic’ animals than are living coral.

“Cryptic animals are merely concealed creatures, that incorporate tiny crabs, fishes, snails and worms – all of which cover in the nooks and crannies of the reef to avoid predation.

“And just like on land with little bugs and bugs, biodiversity in the sea can be dominated by these small invertebrates.”

As these creatures test to continue being concealed, getting and surveying them needs certain care and notice.

Dr Wolfe teamed up with UQ Innovate to structure 3D-printed coral stacks referred to as RUBS (RUbble Biodiversity Samplers), to study cryptic animals on coral reefs.

The 3D-printed ‘coral’ mimics the surrounding reef rubble, seamlessly inviting concealed reef organisms to be unknowingly monitored.

“Every piece of coral or rubble is diverse,” Dr Wolfe stated.

“RUBS deliver a uniform method to study the hidden bulk on coral reefs.

“By sampling the RUBS’ buildings about time, the team had been able to establish changes in the cryptic population, adding parts to the puzzle and filling in the unknowns of coral reef food stuff webs.

“This knowledge fills important know-how gaps, this sort of as how smaller cryptic animals support coral reefs from the bottom of the food stuff chain, all the way up to greater predators.”

Dr Wolfe believes that the new system is one more step in far better understanding our precious reefs – whether considered ‘alive’ or ‘dead’.

“We’re truly pulling back the curtain on just how alive these ‘degraded’ reefs are,” he mentioned.

“These are significant habitats, which support coral reef biodiversity and critical meals webs.

“This new technology is a new opportunity for reef management, notably for reef education and recognition.

“We’re energized to study about and celebrate the range of life in this misunderstood habitat.”

The research has been published in Methods in Ecology and Evolution (DOI: 10.1111/2041-210X.13462).

It was a collaboration in between UQ’s College of Biological Sciences and the ARC Centre of Excellence for Coral Reef Scientific tests.
