Understanding speciation, the splitting of one species into two, is essential for our understanding of biodiversity and sound conservation policy. My research group has made key discoveries regarding speciation, using model systems of birds and salamanders of western Canada as well as other regions of North America and Eurasia. Given our prior research on a variety of species complexes (i.e. groups of closely related species or subspecies that hybridize where they meet), we are now well poised to conduct pioneering research on the relationship between patterns of genomic evolution (i.e. changes in DNA) and patterns of trait differentiation and reproductive isolation among populations. During the next five years, we will conduct research that advances

了解物种形成，即一个物种分裂成两个物种，对于我们理解生物多样性和合理的保护政策至关重要。我的研究小组利用加拿大西部以及北美和欧亚大陆其他地区的鸟类和蝾螈的模型系统，在物种形成方面取得了重大发现。鉴于我们之前对各种物种复合体（即密切相关的物种或亚种在相遇时杂交的群体）的研究，我们现在已经准备好对基因组进化模式（即DNA变化）与种群间性状分化和生殖隔离模式之间的关系进行开创性的研究。在接下来的五年里，我们将进行更先进的研究
