World Ocean Day 2022: Restoring our Lost Reef Ecosystems

Today we celebrate World Ocean Day! Environment Institute marine researchers are using the natural relationships between bivalves and macroalgae to enhance the restoration of South Australia’s lost reef ecosystems. Over 150 years ago, oyster reefs, kelp forests, and seagrass meadows lined the South Australian coastline. These ecosystems provided a rich and productive marine environment but […]

Baby oysters follow the crackling sound of snapping shrimp

Though oysters may be brainless bivalves, they can “hear” and swim towards attractive sounds of the sea. We played the crackling sound of snapping shrimp, which indicates a healthy reef, to baby oysters using underwater speakers. We discovered the oysters swim towards the sound.  This opens the possibility of playing marine sounds to attract oysters […]

International joint research reveals how fish adapt to ocean acidification by modifying gene expression

Human-driven global change is challenging the scientific community to understand how marine species might adapt to predicted environmental conditions in the near-future. The effects of the uptake of anthropogenic atmospheric CO2 by oceans affects propagate across the biological hierarchy, from changes in the building blocks of life at nano-scales to organism, physiology and behaviour through ecosystem […]

Research highlights competing impacts of warm waters and acidification in Nature Paper

Warming waters and ocean acidification could have opposing effects on the movements of tropical fish. Under increasing global warming, tropical fish are escaping warmer seas by extending their habitat ranges towards more temperate waters. But a new study from the University of Adelaide, published in Nature Climate Change, shows that the ocean acidification predicted under […]

Fish sex organs boosted under high-CO2

Research from the University of Adelaide has found that some species of fish will have higher reproductive capacity because of larger sex organs, under the more acidic oceans of the future. Published in PLOS Biology, the researchers say that far from the negative effects expected under the elevated CO2 levels in our oceans predicted for the end […]

The world’s leading aquatic scientific societies with 80,000+ members urgently call for cuts to global greenhouse gas emissions

Dire consequences for freshwater and marine resources without significant and fast action. In an unprecedented statement released recently, the American Fisheries Society (AFS) joined forces with 110 aquatic scientific societies representing more than 80,000 scientists across the world to sound a climate change alarm.  The societies call for drastically curtailed global greenhouse gas emissions to […]
