Water resource management is a key issue for environmental sustainability in Australia and strategies that include ecological principles are important to improve present conditions and reduce further degradation. Current biomonitoring methods suffer from a low degree of sensitivity that can seriously impact their effectiveness as early warning signals of ecological disturbance. We propose to combine molecular and ecotoxicological assessment of the effect of zinc toxicity on microbial communities to provide rapid pollution sensitive bioassessment. Our research will lead to a better understanding of the cause and effect of heavy metal pollution within aquatic ecosystems and greater insight on how to reduce and repair the negative effects.

水资源管理是澳大利亚环境可持续性的一个关键问题，包括生态原则在内的战略对于改善目前的状况和减少进一步退化十分重要。目前的生物监测方法灵敏度低，可能严重影响其作为生态扰动预警信号的有效性。我们建议联合收割机的分子和生态毒理学评估锌毒性对微生物群落的影响，提供快速的污染敏感的生物评估。我们的研究将导致更好地了解水生态系统中重金属污染的原因和影响，并更深入地了解如何减少和修复负面影响。
