摘要识别种群遗传结构有助于推断进化过程，并将所得结构与亚种边界进行比较，有助于物种管理。美国红隼（Falco sparverius）是一种分布广泛且高度多样的物种，共有17个亚种，其中只有2个在美国北部被发现。墨西哥边境（F。S. paulus仅分布于美国东南部，而F. S. Sparverius在美国和加拿大分布的其余部分中繁殖）。在美国和加拿大的许多地区，美洲红隼的数量一直在下降，但如果不更清楚地了解种群之间的基因流动，就很难解释人口趋势。在这里，我们对第一个美国红隼基因组进行测序，并扫描来自美国和加拿大12个采样点的197个个体的基因组，以确定种群结构。为了验证种群结构的特征并填补美国和加拿大范围内的采样空白，我们从34个采样地点的另外376个样本中筛选了192个离群位点。总体而言，我们的分析支持存在5个遗传上不同的种群的美国红隼东部，西部，得克萨斯州，佛罗里达，阿拉斯加。有趣的是，我们发现，虽然我们的全基因组遗传数据支持先前描述的美国和加拿大亚种边界的存在，但整个采样范围的遗传差异与推定的迁移表型（居民，长途和短途移民）相关性更高，而不是先验描述的亚种边界本身。根据我们的研究结果，我们建议由此产生的5个遗传上不同的种群作为美国红隼保护和管理的基础，面对未来的威胁。美洲红隼（Falco sparverius）是一种分布广泛的标志性猛禽物种，在过去的几十年里，它的丰度呈现出高度可变的趋势。在这里，我们对第一个美国红隼基因组进行测序，并扫描基因组的遗传变异，以确定美国和加拿大育种范围内的五个遗传上不同的种群。由此产生的遗传变异图（基因图谱）可以作为检验假设的基础，以解释观察到的特定人群对气候变化和其他压力的反应。
ABSTRACT Identifying population genetic structure is useful for inferring evolutionary process and comparing the resulting structure with subspecies boundaries can aid in species management. The American Kestrel (Falco sparverius) is a widespread and highly diverse species with 17 total subspecies, only 2 of which are found north of U.S./Mexico border (F. s. paulus is restricted to southeastern United States, while F. s. sparverius breeds across the remainder of the U.S. and Canadian distribution). In many parts of their U.S. and Canadian range, American Kestrels have been declining, but it has been difficult to interpret demographic trends without a clearer understanding of gene flow among populations. Here we sequence the first American Kestrel genome and scan the genome of 197 individuals from 12 sampling locations across the United States and Canada in order to identify population structure. To validate signatures of population structure and fill in sampling gaps across the U.S. and Canadian range, we screened 192 outlier loci in an additional 376 samples from 34 sampling locations. Overall, our analyses support the existence of 5 genetically distinct populations of American Kestrels—eastern, western, Texas, Florida, and Alaska. Interestingly, we found that while our genome-wide genetic data support the existence of previously described subspecies boundaries in the United States and Canada, genetic differences across the sampled range correlate more with putative migratory phenotypes (resident, long-distance, and short-distance migrants) rather than a priori described subspecies boundaries per se. Based on our results, we suggest the resulting 5 genetically distinct populations serve as the foundation for American Kestrel conservation and management in the face of future threats. LAY SUMMARY The American Kestrel (Falco sparverius) is a widespread iconic raptor species that has shown highly variable trends in abundance over the last several decades. Here we sequence the first American Kestrel genome and scan the genome for genetic variation in order to identify five genetically distinct populations across the U.S. and Canadian breeding range. The resulting map of genetic variation (the genoscape) can serve as a foundation for testing hypotheses to explain observed population-specific responses to climate change and other stressors.
