Abstract
Abigail Scott studied how herbivore grazing can modify seagrass meadows in the Great Barrier Reef. She found that herbivores act as ecosystem engineers in these seagrass meadows, particularly green turtles and dugong. Abigail's results will be used to inform seagrass monitoring on the Great Barrier Reef.
