Few single biodiversity programs span genes, species and communities, yet the three are linked: genetic diversity is the raw material for speciation; species are the currency for comparison of habitats and sites; and communities are strongly influenced by species interactions. By assessing diversity at all three scales, we move toward a greater understanding of mechanisms and resulting patterns of diversity. I explore insect diversity at genetic, species and ecological scales. My study taxon is the flies (Diptera), Canada's most diverse order of insects. My short-term objective is to document patterns of diversity at all three levels at multiple spatial scales, especially in the arctic where flies dominate. My long-term objective is to build a phylogenetic and ecological framework to address questions on the diversity and dominance of flies. We explore three themes:

很少有单一的生物多样性项目跨越基因、物种和群落，但这三者是联系在一起的：遗传多样性是物种形成的原材料；物种是比较生境和地点的货币；群落受到物种相互作用的强烈影响。通过在这三个尺度上评估多样性，我们对多样性的机制和结果模式有了更深入的了解。我在遗传、物种和生态尺度上探索昆虫的多样性。我的研究分类是苍蝇（双翅目），这是加拿大种类最多的昆虫。我的短期目标是在多个空间尺度上记录所有三个层次的多样性模式，特别是在苍蝇占主导地位的北极。我的长期目标是建立一个系统发育和生态框架，以解决有关苍蝇多样性和优势性的问题。我们探讨了三个主题：
