An understanding of processes generating temporal and spatial patterns of genetic diversity in perennial plants must underpin successful conservation. Our long-term study will exploit systems in the family Proteaceae in which we have completed foundation studies. We will develop and extend molecular techniques to measure (i) genetic changes from seed to adult, (ii) gene flow by different pollinator classes, and (iii) genetic contamination by foreign gene pools, in systems affected by introduced pollinators and natural and cultivar hybridization. Most importantly, we will use fire as an accelerant of generational change and test fitness consequences of changes in genotypic diversity.

了解多年生植物遗传多样性的时空格局的产生过程，是成功保护的基础。我们的长期研究将利用我们已经完成基础研究的Proteaceae家族中的系统。我们将开发和扩展分子技术，以测量（一）从种子到成人的遗传变化，（二）不同传粉者类的基因流，和（三）外来基因库的遗传污染，在引入传粉者和自然和品种杂交的影响系统。最重要的是，我们将使用火作为世代变化的促进剂，并测试基因型多样性变化的适应性后果。
