Marine food webs struggle as climate change increases sea temperatures

Scientists at the University of Adelaide have found growing evidence that marine ecosystems will not cope well with rising sea temperatures caused by climate change. “Healthy food webs are critical for ecosystems so that the world’s oceans can continue to provide an important source of food for humans,” says lead author Professor Ivan Nagelkerken, from the University […]

A broad diet helps tropical fish survive a range shift due to climate change

The global redistribution of marine and terrestrial species due to climate change is a major concern for conservation planners and resource managers. Now new research, using data from long term surveys of tropical fishes, indicates that traditional studies of this range shift phenomenon largely ignore the sequential nature of species movement. The study, published in […]

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 […]

Can we meet the UN challenge to restore coastal wetlands by 2030?

As the UN declares the 2020s the ‘Decade of Ecosystem Restoration’, Professor Ivan Nagelkerken has collaborated with scientists worldwide to overcome the challenges of costal restorations. Leading coastal scientists from all over the world have joined forces calling for unified action on the future of coastal ecosystem conservation and restoration. This call comes in response to a declaration […]

PAPER: Tropical and temperate species are living well together under climate change

Researchers at the University of Adelaide have found tropical and temperate coral reef fish can co-exist. As our climate changes, many terrestrial and marine species are forced to extend their ranges poleward, to stay within the bounds of their thermal tolerances. However, when such species enter higher latitude ecosystems, they engage in innovative interactions with local […]

Climate change drives collapse in marine food webs

A new study has found that levels of commercial fish stocks could be harmed as rising sea temperatures affect their source of food. University of Adelaide scientists have demonstrated how climate change can drive the collapse of marine “food webs”. To be published on 10 January in the open access journal PLOS Biology, the study’s […]

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: 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’, […]
