  • First semester 2017 (Day)


This unit investigates the organisms and the processes that drive marine ecosystems. We deal with the trophic structure of marine ecosystems, including primary and secondary production, microbial loops, food webs and their importance for marine fisheries. The implications of the characteristic life cycles of marine organisms to their geographical distribution are also considered. These topics are placed in the context of specific marine ecosystems including coastal habitats, coral reefs, open oceans, the deep sea and polar ecosystems. The practical component comprises a field trip (fee payable) either to Heron Island in December or the Queenscliff Marine Station in February where students work in small groups on specific aspects of marine biology.


On completion of this unit students will be able to:

  1. Describe the diversity and ecological importance of marine life;
  2. Explain the fundamental physiochemical and physiological processes underlying the productivity of marine environments;
  3. Explain the ecological dynamics of marine ecosystems;
  4. Discuss the impact of human activity on the sustainability of marine ecosystems;
  5. Demonstrate advanced scientific skills in project design, data collection, analysis and writing.


Examination (2.5 hours): 50%
