Ocean warming and acidification are changing shark behaviour

Posted on August 23, 2016 by Noby Leong

sharks 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 Sean Connell has uncovered the climate-sensitive metabolic and behavioural changes of large predators.

The paper, entitled “Antagonistic effects of ocean acidification and warming on hunting sharks” was published in August, 2016 in Oikos.

The research has already received extensive media coverage, with Channel 9 producing a news special. The video was broadcast during the 6pm news on the 17th of August, and the Facebook upload received more than 50,000 hits within 24 hours. For more from this research group, you can read an interview by Assoc. Prof Nagelkerken with Discover Magazine.

Media Release: Baby fish led astray by high CO2 in oceans

Baby fish will find it harder to reach secure shelters in future acidified oceans – putting fish populations at risk, new research from the University of Adelaide has concluded. Published today in the Nature journal Scientific Reports, the researchers described how barramundi larvae in high CO2 conditions, predicted for the turn of the century, turn […]

LISTEN: Radio Adelaide Interview about how Climate Change is collapsing food webs

Environment Institute members Professor Sean Connell, Associate Professor Ivan Nagelkerken, and PhD candidate Silvan Goldenberg spoke to Radio Adelaide recently. They discussed their recently published work on how climate change could possible destabilise our coastal food webs, and what we can do to help. Listen to their full interview Radio Adelaide’s website, or read their […]

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 […]

Seminar: New methods to assess ocean oxygenation

The next Sprigg Seminar will be presented by Dr Babette Hoogakker from the University of Oxford with her talk entitled “New methods to assess ocean oxygenation in the past; examples from the Atlantic and Southern oceans.” Title: New methods to assess ocean oxygenation in the past; examples from the Atlantic and Southern oceans When: 4pm, Thursday 27 October, […]

Podcast: Jumping the shark

Global warming of our oceans is having an impact across the marine environment. Associate Professor Ivan Nagelkerken from the University of Adelaide’s Environment Institute was interviewed recently by Ewart Shaw on Radio Adelaide about his research into the challenges faced by sharks due to increasing ocean temperatures.

Media release: Sharks’ hunting ability destroyed under climate change

The hunting ability and growth of sharks will be dramatically impacted by increased CO2 levels and warmer oceans expected by the end of the century, a University of Adelaide study has found. Published in the journal Scientific Reports, marine ecologists from the University of Adelaide’s Environment Institute report long-term experiments that show warmer waters and […]

Saving the Grey Nurse Shark.

The number of grey nurse sharks around the world has declined, in Australia they are now classified as Critically Endangered. Associate Professor Corey Bradshaw, from the University of Adelaide’s Environment Institute, was invited by the Department of the Environment, Water, Heritage and the Arts to attend a forum held at the Sydney Institute of Marine […]
