Insect diversity at multiple scales: from genes to communities

很少有单一的生物多样性计划跨越基因，物种和社区，但三者是相互联系的：遗传多样性是物种形成的原材料;物种是比较栖息地和地点的货币;社区受到物种相互作用的强烈影响。通过在所有三个尺度上评估多样性，我们可以更好地理解多样性的机制和由此产生的模式。我探索昆虫在遗传，物种和生态尺度的多样性。我的研究分类是苍蝇（双翅目），加拿大最多样化的昆虫。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地区。我的长期目标是建立一个系统发育和生态框架，以解决苍蝇的多样性和优势的问题。我们探讨三个主题：

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:
