Description Temperate freshwater, estuarine and marine aquatic ecosystems play vital roles in providing food, water, recreation and other ecosystem services to human society and habitats for important species that make up global biodiversity. Yet aquatic habitats are the most threatened ecosystems on earth, under threat from global climate change and urbanisation. Through inquiry and problem solving this subject will equip students with the necessary techniques in experimental design and analysis needed to investigate aquatic ecosystems and knowledge of the main animal and plants in aquatic and marine ecosystems. The logic and philosophy of science, scientific studies and experimental analyses will be used to understand temperate aquatic ecosystems throughout this subject. On completion students will have the background knowledge and skills communicate to a range of audiences, so that they can contribute beneficially to management and/or conservation of waterways and oceans and the biodiversity within.

Assumed Knowledge
Concepts of classification, evolution, taxonomy, cellular processes plant and animal structure and function, normal distribution, representative sampling, probability and uncertainty.
Learning Outcomes
- Describe the main characteristics of aquatic habitats including estuarine, freshwater and marine and use taxonomic keys and other methods to identify organisms where appropriate to species level in freshwater, estuarine and marine habitats.
- Describe, use and evaluate methods of experimental design and analysis of statistical data in studies in freshwater, estuarine and marine aquatic habitats.
- Describe the main models which explain factors affecting macrofaunal and floral assemblages in estuarine and marine aquatic habitats.
- Use and critically evaluate scientific studies to support or reject hypotheses developed and tested within freshwater, estuarine and marine aquatic habitats.
- Construct experimental designs developed to assess human impacts on aquatic systems and explain these using a philosophical and historical basis of thinking.
- Demonstrate scientific thinking and communication through the preparation of scientific reports which describe student investigations of aquatic habitats. This involves planning and implementing of experimental designs, selection of appropriate tools to collect representative samples, analyse data and synthesis ideas from the literature to support the main conclusions reached in the investigation.
- Demonstrate and discuss your appreciation that 70% of our world is covered by aquatic environments and that humans have a responsibility to conserve the biodiversity within for future generations.
