• Drift-kelp suppresses foraging movement of overgrazing sea urchins

  Australian Ocean Data Network (AODN)

  Sea urchins have the capacity to destructively overgraze kelp beds and cause a wholesale shift to an alternative and stable ‘urchin barren’ state. However, their destructive grazing behaviour can be highly labile and contingent on behavioural shifts at the…

• Pollution markers at ecological monitoring sites (NESP MB C2)

  Australian Ocean Data Network (AODN)

  Investigations of the impact of sewage and heavy metal inputs on inshore rocky reef communities have been limited to date because the scale of information on levels of pollutants has been much broader than the span of transects at sites investigated. As a…
