University of Adelaide researchers have constructed a marine food web to show how climate change could affect our future fish supplies and marine biodiversity.
Published today in Global Change Biology, the researchers found that high CO2 expected by the end of the century which causes ocean acidification will boost production at different levels of the food web, but ocean warming cancelled this benefit by causing stress to marine animals, preventing them using the increased resources efficiently for their own growth and development. The result was a collapsing food web.
“Humans rely heavily on a diversity of services that are provided by ocean ecosystems, including the food we eat and industries that arise from that,” says project leader Professor Ivan Nagelkerken, from the University’s Environment Institute.
