Overview of thesis

I am investigating herbivory within temperate southwest Australian seagrass meadows. Temperate seagrass habitats are characterized by predominantly omnivorous fishes that exert very little direct control on seagrass production. Climate change-induced tropicalisation has seen the arrival of the tropical herbivore Siganus fuscescens in temperate coastal waters. I am exploring questions regarding the diets of a number of temperate fish species, and comparing them to S. fuscescens, and additionally comparing the diet of S. fuscescens across different climate zones.
