The effects of chemical stressors (e.g. salinity, pesticides or metals) on freshwater ecological systems: • The effect of chemicals on individuals, populations and/or community in real streams • Ecosystems functions/processes and services • Comparing the effects of chemicals in the laboratory, mesocosms and real streams • The importance of indirect effects Improved ecological realistic methods of assessing the risk of environmental stressors/contaminants • Obtaining representative samples of species sensitivity to toxicants • New statistical methods How do environmental stressors affect the traits of freshwater organisms? • Stream invertebrates • Diatoms sensitivity to herbicides • Trait based diagnostic biomonitoring The ecology of streams in the Australian Alps along an altitude gradient • Population and community dynamics • Ecosystem functions/processes
