Irreversible behavioural impairment of fish starts early: Embryonic exposure to ocean acidification

Researchers from the Marine Biology Program at the University of Adelaide have made critical discoveries about the impacts of embryonic exposure to ocean acidification. Long-term species responses to ocean acidification depend on their sensitivity during different life stages. Scientists tested for sensitivity of juvenile fish behaviour to ocean acidification by exposing eggs to control and […]

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 […]

Sea Snails adapt to extreme acidity levels, living in CO2 vent off NZ

New research published today in Current Biology describes a species of gastropod (sea snail) which lives in very acidic water near a CO2 vent in the southwest Pacific near New Zealand. This is the first instance of Sea snails growing in such acidic conditions, which is more than 30 times higher than normal seawater. Sea snails grow their […]

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 […]

New Paper: Rising CO2, Ocean Acidification and Food Web Collapse

A new paper published in Global Change Ecology shows our coastal food webs could be on the brink of collapse due to rising CO2 levels causing oceans acidification. The research led by Environment Institute Member, Silvan Goldenberg, a PhD candidate found that increased temperature and CO2 levels had an overall detrimental effect on their simulated ocean environment. Environment […]

Best Student Oral Presentation

The Environment Institute would like to congratulate PhD student Tullio Rossi on winning the best student oral presentation at the 4th International Symposium on the Ocean in a High CO2 World in Hobart recently, for his presentation, ‘Ocean acidification leaves dispersing fish larvae lost at sea,’ Rossi.T, Nagelkerken.I, Connell.S.D (2016). This is the largest global […]

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 […]

Ocean acidification leaves fish lost at sea

Associate Professor Ivan Nagelkerken, Professor Sean Connell, Tullio Rossi and Jennifer Pistevos from the University of Adelaide were involved in an article published in the journal Biology Letters, entitled, “Lost at sea: ocean acidification undermines larval fish orientation via altered hearing and marine soundscape modification.” Their research highlights future complications for fish due to stresses […]

Podcast: Ocean acidification could cause fish to be lost at sea

New research shows that increased CO2 levels interfere with the ability of baby fish to find a home. Sarah Martin from Radio Adelaide spoke with University of Adelaide marine biology PhD student Tullio Rossi about his research into the effects of ocean acidification on fish behaviour. Listen to the full interview.

Media release: Baby fish will be lost at sea in acidified oceans

The ability of baby fish to find a home, or other safe haven, to grow into adulthood will be severely impacted under predicted ocean acidification, University of Adelaide research has found. Published today in the journal Proceedings of the Royal Society B, the researchers report the interpretation of normal ocean sound cues which help baby […]
