概括
研究人员开发了MPG牧场关节动物图书馆 (MPG-AL),这是蒙大拿州关节动物的DNA条形码参考图书馆. 这大大扩展了区域DNA条形码数据,有助于北方落基山脉的生态研究.
科学领域:
- 生态生态学 生态生态学
- 基因组学就是基因组学.
- 生物多样性 生物多样性
背景情况:
- 关节动物DNA条形码参考图书馆对于生态研究至关重要,但在美国西部的覆盖范围有限.
- 蒙大拿州现有的图书馆是不完整的,阻碍了全面的生态研究.
研究的目的:
- 开发MPG牧场关节动物图书馆 (MPG-AL),这是蒙大拿州中西部关节动物的细胞氧化酶I (COI) DNA条形码参考图书馆.
- 为了提高关节动物DNA条形码的分类学覆盖范围,在北方洛基山脉生态区域.
主要方法:
- 在2017年至2019年期间,从蒙大拿州中西部的各种息地收集了86,533只节肢动物标本.
- 产生了52 270个关节动物类的DNA条形码,分布在38个类.
- 将MPG-AL数据与现有的公共数据库进行比较 (BOLD,蒙大拿州自然遗产计划).
主要成果:
- MPG-AL将5154个条形码索引号 (BIN) 添加到生活条形码数据库 (BOLD),代表蒙大拿州增加了280%.
- 对于以前缺乏参考条形码序列的类型,新增了1140个BIN.
- 图书馆涵盖38个顺序,389个家族,1668个属和1793个物种.
