New research from Edith Cowan University (ECU) has identified a smarter, more effective way to protect fragile marine ecosystems from invasive species—an approach with global relevance for island regions around the world. The study, led by Professor Marnie Campbell, Executive Dean of ECU's School of Science, draws on her long-standing research in the Galápagos Islands, where introduced marine pests pose a growing threat to one of the world's most iconic natural environments.
