Climate change to affect fish sizes and complex food webs

Global climate change will affect fish sizes in unpredictable ways and, consequently, impact complex food webs in our oceans, a new Institute for Marine and Antarctic Studies (IMAS)-led study has shown.

Led by IMAS and Centre for Marine Socioecology scientist Dr Asta Audzijonyte and published in the journal Nature Ecology and Evolution, the study analysed three decades of data from 30,000 surveys of rocky and coral reefs around Australia.

Dr Audzijonyte said the study confirmed that changes in water temperature were responsible for driving changes in average sizes of fish species across time and spatial scales. MORE
