- the effects of disturbances on reef communities and processes of subsequent recovery.
- the ecology of Acanthaster planci, the crown-of-thorns starfish, which has been the major cause of losses of living coral on the GBR in recent decades
- "ecosystem health" particularly as applied to coral reefs
- the effects of marine reserves.
