Funding Acknowledgements

Funding for this research was provided by Melbourne Water Corporation, the Victorian Department of Business and Innovation through support of the Centre for Aquatic Pollution Identification and Management, and the Australian Research Council through their Fellowship scheme. Chemical analyses of overlying water, pore water and sediment were carried out by ALS Group, Environmental Division Melbourne and Sydney, and by CSIRO Land and Water (Lucas Heights, NSW). Thank you to: Sandra Lagauzere for providing valuable suggestions on the methodology; Sara Long (CAPIM) for providing acute, water-only, ammonia toxicity data to C. tepperi; Mark Stevens (NSW Department of Primary Industries) for the original supply of C. tepperi eggs. We are thankful to the two anonymous reviewers whose constructive comments and suggestions greatly improved this manuscript.
