For reefs facing huge challenges, more coral larvae doesn’t necessarily translate to increased rates of coral recovery on degraded reefs, a new Queensland study has showed.

The study, published today, was led by former University of Queensland School of Biological Sciences researcher Dr Christopher Doropoulos, now of CSIRO Oceans and Atmosphere, and involved collaboration with CSIRO, the University of Queensland, and Griffith University.

“Overall, our research shows that excessively high or low densities of coral larvae do not contribute to reef recovery,” said Dr Doropoulos.

“When larval supply is too low, corals tend not to attach to the reef because they have aggregative behaviour; they prefer to colonise in groups.

“On the other hand, when larval densities are extremely high, the post-settlement survival of corals is low because internal feedbacks regulate populations so they don’t grow in excess.”
