A University of Adelaide study of shallow-water fish communities on rocky reefs in south-eastern Australia has found climate change is helping tropical fish species invade temperate Australian waters. The work is published in the Journal of Animal Ecology.
"The fish are traveling into these Australian ecosystems as larvae caught in the Eastern Australian Current, which is strengthening due to the warming climate," said the University of Adelaide's Professor Ivan Nagelkerken, Chief Investigator of the study.
