Environmental disturbances shape the dynamics of the world's ecosystems. However, we do not understand how they influence biodiversity at its most fundamental level, genetic diversity. This is important, because genetic diversity affects the fitness of individuals, the viability of populations and the adaptability of species. This project will study fire in the Australian environment to discover how disturbance affects genetic diversity. By integrating landscape genomics and computational modelling with long-term field studies, the research will significantly advance our understanding of how genetic diversity is distributed, and improve our ability to predict the responses of natural populations to changes in the frequency and severity of wildfire.

环境干扰影响着世界生态系统的动态。然而，我们不了解它们如何影响生物多样性的最基本层面，即遗传多样性。这一点很重要，因为遗传多样性影响到个体的适应性、种群的生存能力和物种的适应性。该项目将研究澳大利亚环境中的火灾，以发现干扰如何影响遗传多样性。通过将景观基因组学和计算建模与长期实地研究相结合，这项研究将大大提高我们对遗传多样性如何分布的理解，并提高我们预测自然种群对野火频率和严重程度变化的反应的能力。
