As part of our Reef Matters Seminar Series, we are pleased to present the work of Professor Maria Byrne (2019 ACRS Established Researcher) and her student Dione Deaker (2020 ACRS Terry Walker awardee) from the University of Sydney. Their talks, titled “Filling in pieces of the crown-of-thorns puzzle” explores the fascinating life history and behaviour of the crown of thorns starfish and how these findings may help shape future management decisisons for Australia’s coral reefs.
