Dr Casey Benkwitt
Casey is broadly interested in the behavioural, population, and community ecology of reef fishes, with a focus on how human activities influence these processes. Examples of previous research projects include investigating the effects of an invasive marine predator on native coral-reef fishes and the effects of different fishing regimes on sex-changing fishes in kelp forests. Casey’s current research focuses on how nutrient subsidies from seabirds nesting on islands influence adjacent coral reefs. Specifically, she is testing whether the presence of seabirds boosts the resistance and/or recovery of coral-reef communities following mass coral bleaching events. She is also investigating how management actions to remove invasive rats and restore seabird populations affect coral reefs.
