Overview of thesis

Coastal ecosystems and the services they provide are under immense pressure due to a wide range of human influences. Seagrasses provide critical coastal ecosystem and socioeconomic services, but there is substantial evidence indicating that they are declining at disturbing rates across the globe. They form the foundation of many major aquatic food chains and are a main food source for herbivores such as waterfowl, dugongs and turtles. Herbivory plays a key role in influencing the community structure and ecological processes within the seagrass ecosystem. Climate change is predicted to have profound impacts upon marine ecosystems, and seagrasses are no exception. My research will investigate the combined effects of herbivory and temperature increases that are induced by climate change on the resilience of seagrass in Western Australia.
