Native fish populations in Australian ephemeral rivers are highly valued but are subject to widespread decline. During drought waterholes serve as critical refuges for native fish, however thermal extremes and hypoxia (lack of oxygen) have led to regular fish-kill events. Whilst we know the general conditions that lead to fish-kills, we do not have a clear understanding of why some species are more tolerant than others, or how we can help decision-makers anticipate fish-kill risks. This project will combine laboratory ecophysiology investigations and novel field monitoring techniques to develop a next-generation fish habitat model for stakeholders to use to assess fish-kill risks and plan for restoration.

澳大利亚短暂河流中的本地鱼类种群价值很高，但正在普遍下降。在干旱期间，水坑是本地鱼类的重要避难所，然而极端高温和缺氧（缺氧）导致经常性的鱼类死亡事件。虽然我们知道导致鱼类死亡的一般条件，但我们并不清楚为什么有些物种比其他物种更宽容，或者我们如何帮助决策者预测鱼类死亡风险。该项目将结合联合收割机实验室生态生理学调查和新的现场监测技术，开发下一代鱼类栖息地模型，供利益相关者用于评估鱼类死亡风险和恢复计划。
