Owl monkeys (genus ), or "night monkeys" are platyrrhine primates in the Aotidae family. Early taxonomy only recognized one species, , until 1983, when Hershkovitz proposed nine unique species designations, classified into red-necked and gray-necked species groups based predominately on pelage coloration. Recent studies questioned this conventional separation of the genus and proposed designations based on the geographical location of wild populations. retrotransposons are a class of mobile element insertion (MEI) widely used to study primate phylogenetics. A scaffold-level genome assembly for one species, [Anan_2.0], facilitated large-scale ascertainment of nearly 2000 young lineage-specific insertions. This study provides candidate oligonucleotides for locus-specific PCR assays for over 1350 of these elements. For 314 elements across four taxa with multiple specimens, PCR analyses identified 159 insertion polymorphisms, including 21 grouping and (red-necked species) as sister taxa, with and (gray-necked) being more basal. DNA sequencing identified five novel elements from three different taxa. The datasets reported in this study will assist in species identification and provide a valuable resource for phylogenetics, population genetics and conservation strategies when applied to wild populations.
鸮猴属(属),或“夜猴”,是 Aotidae 科的阔鼻猴。早期的分类学只承认一个物种,直到 1983 年,赫什科夫茨(Hershkovitz)提出了九个独特的物种命名,根据主要基于皮毛颜色的分类,分为红颈种和灰颈种。最近的研究对这种传统的属的分类提出了质疑,并根据野生种群的地理位置提出了命名。逆转录转座子是一类广泛用于研究灵长类系统发育的移动元件插入(MEI)。一个鸮猴物种的支架水平基因组组装, ,[Anan_2.0],促进了近 2000 个年轻谱系特异性插入的大规模确定。这项研究为超过 1350 个这些元素的基因座特异性 PCR 检测提供了候选寡核苷酸。对于四个具有多个标本的分类单元的 314 个元素,PCR 分析鉴定出 159 个插入多态性,包括将和(红颈种)作为姐妹分类单元,和(灰颈种)更为基础。DNA 测序从三个不同的分类单元中鉴定出五个新的 元素。本研究报告的数据集将有助于物种鉴定,并为种系发生学、群体遗传学和保护策略提供有价值的资源,应用于野生种群。
