Changes in marine ecosystems going undetected
Existing ways of calculating biodiversity dynamics are not very effective in detecting wholesale species community change due to the effects of ocean acidification. University of Adelaide research shows that in cases where biodiversity metrics show no change or little change, there may still be reorganisation of ecological communities in our oceans. “The belief that climate […]

Ocean acidification and warming disrupts fish shoals
Researchers from the University of Adelaide have found that the way fish interact in groups is being upset by ocean acidification and global warming. “Fish show gregarious behaviour and cluster in shoals which helps them to acquire food and for protection against predators,” said project leader Professor Ivan Nagelkerken from the University of Adelaide’s Environment […]

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 […]

University of Adelaide research featured in New York Times – Shrimp snaps soften
Climate change is changing the way nature sounds. Professor Ivan Nagelkerken team’s research has been featured in a New York Times article which covers how climate change will silence some species and push others into new habits and habitats, changing when and where they sing, squeak, whistle, bellow or bleat. It will also change the sound […]

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 […]
