Single nucleotide polymorphisms across a species' range: implications for conservation studies of Pacific salmon

Studies of the oceanic and near-shore distributions of Pacific salmon, whose migrations typically span thousands of kilometers, have become increasingly valuable in the presence of climate change, increasing hatchery production, and potentially high rates of bycatch in offshore fisheries. Genetics data offer considerable insights into both the migratory routes as well as the evolutionary histories of the species. However, these types of studies require extensive datasets from spawning populations originating from across the species? range. Single nucleotide polymorphisms (SNPs) have been particularly amenable for multi-national applications because they are easily shared, require little inter-laboratory standardization, and can be assayed through increasingly efficient technologies. Here we discuss the development of a dataset for 114 populations of chum salmon through a collaboration among North American and Asian researchers, termed PacSNP. PacSNP is focused on developing the database...针对迁徙距离通常可达数千公里的太平洋鲑鱼海洋及近岸分布的研究，在气候变化、孵化场养殖规模持续扩大以及近海渔业可能存在较高兼捕率的背景下，其学术与应用价值日益凸显。遗传学数据可为该物种的迁徙路径与演化历史提供极具价值的见解。然而，此类研究需要覆盖该物种整个自然分布范围内所有产卵种群的大规模数据集。单核苷酸多态性（Single Nucleotide Polymorphisms, SNPs）尤其适用于跨国研究场景，因其具备易于共享、无需复杂实验室间标准化流程、可通过日益高效的技术手段完成分型检测等优势。本文探讨了由北美与亚洲研究人员合作构建的、针对114个狗鲑（chum salmon）种群的数据集PacSNP的开发历程。PacSNP项目旨在构建该数据库……
