Ocean soundscape researchers hit SCOPE TV

Oceans aren’t as silent as you think – it’s a noisy place filled with snapping shrimp and crashing waves, as our researchers explain on the latest episode of SCOPE. Marine animals use sound to navigate through the ocean. Larvae for example use the sounds of the sea to find their way back home. Professor Ivan Nagelkerken […]

Media release: Barramundi populations at risk from acid oceans

Wild barramundi populations are likely to be at risk under ocean acidification, a new University of Adelaide study has found. Published in the journal Oecologia, the study is the first to show that even freshwater fish which only spend a small portion of their lifecycle in the ocean are likely to be seriously affected under […]

Media Release: Climate change will see some males get sexier

A common marine crustacean has shown researchers that it’s all set to beat climate change – the males will get more attractive to the females, with a resulting population explosion. The University of Adelaide study is the first to show how mating behaviour could change under the warmer waters and more acidic oceans brought by […]

Media release: Nutrient pollution is changing sounds in the sea

Nutrient pollution emptying into seas from cities, towns and agricultural land is changing the sounds made by marine life – and potentially upsetting navigational cues for fish and other sea creatures, a new University of Adelaide study has found. Published online in the journal Landscape Ecology, the research found that marine ecosystems degraded by ‘eutrophication’, […]

Ocean warming and acidification are changing shark behaviour

As the Earth’s oceans warms, sea-dwelling creatures experience a raft of changes. While much attention has been directed towards small-bodied fishes, we know relatively little about the effects of ocean warming and acidification on large predators like sharks. A new publication by the Environment Institute’s Jennifer Pistevos, Associate Professor Ivan Nagelkerken, Dr Tullio Rossi and Professor […]

New artificial reef to be built to support local marine habitats

A new $600,000 artificial reef system is to be built south of Ardrossan, informed by research by the Environment Institute’s Professor Sean Connell and PIRSA’s Dr Heidi Alleway. The artificial reef, which is to be constructed from limestone, oyster shells and live native oysters, is part of a $3.52m State Government initiative to enhance the experience […]

Podcast: The silence of the shrimp

PhD candidate Tullio Rossi was interviewed by Radio Adelaide‘s Ewart Shaw. He discusses his research about the silencing of shrimps. Snapping Shrimps are the loudest invertebrate in the ocean, and their peculiar sound, itself a complex scientific phenomenon, is a vital indicator of ocean health and welfare. Tullio Rossi, is also the creator of an award-winning […]

COSMOS Feature: Snapping shrimps silenced

Research showing how shrimps are being silenced, was recently published in Proceedings of the Royal Society B. The research, led by Associate Professor Ivan Nagelkerken, PhD student Tullio Rossi and Professor Sean Connell has been featured in COSMOS Magazine. The researchers recorded the crackle of Alpheus shrimp near naturally acidic underwater vents and found fewer and quieter snaps. Not only does […]

Media Release: Silent oceans: acidification stops shrimp chorus

Snapping shrimps, the loudest invertebrate in the ocean, may be silenced under increasing ocean acidification, a University of Adelaide study has found. Published today in the journal Proceedings of the Royal Society B, the researchers report that under forecast levels of CO2 predicted to be found in oceans by the end of the century, the […]
