Population sizes of species go up and down and often we do not know why. This is a problem because changes in population size underpin more complex ecological change, and understanding why population sizes change affects our ability to manage environmental impacts, and threatened, harvested and pest species. The aim of this project is to discover how rapid evolution – evolution occurring over just a few generations – drives changes in population sizes of plants in Australian freshwater ecosystems. By focusing on this fundamental yet poorly understood process, our results promise to rewrite our understanding of the causes of change in ecological communities, while highlighting a unique and little studied component of Australia’s biota.

物种的种群规模会上下波动，但我们常常不知道原因。这是一个问题，因为人口规模的变化支撑着更复杂的生态变化，而了解人口规模变化的原因会影响我们管理环境影响以及受威胁、收获和害虫物种的能力。该项目的目的是发现快速进化（仅在几代内发生的进化）如何驱动澳大利亚淡水生态系统中植物种群规模的变化。通过关注这一基本但知之甚少的过程，我们的研究结果有望改写我们对生态群落变化原因的理解，同时强调澳大利亚生物群中一个独特且鲜为人知的组成部分。
