The short ninespine stickleback, , is a small gasterosteid species complex containing three geographical lineages: ND, NE and SE. Here, complete mitochondrial genomes of these three lineages were analyzed to estimate the genetic differentiation among them and to identify their phylogenetic placement in genus . Although the overall genome structure was identical among those three lineages, the genome sizes were slightly different from each other, ranging from 16,489 to 16,500 bp. Upon robust phylogenetic tree inferred by Bayesian algorithm, ND and SE showed relatively higher affinity, and those three lineages formed a monophyletic group with Russian , clearly supporting previous studies.
短九刺鱼是一种小型的刺鱼科物种复合体，包含三个地理谱系：ND、NE和SE。在此，对这三个谱系的完整线粒体基因组进行了分析，以估计它们之间的遗传分化，并确定它们在刺鱼属中的系统发育位置。尽管这三个谱系的整体基因组结构相同，但基因组大小彼此略有不同，范围从16,489到16,500 bp。根据贝叶斯算法推断出的稳健系统发育树，ND和SE显示出相对较高的亲缘关系，并且这三个谱系与俄罗斯刺鱼形成了一个单系群，这明显支持了先前的研究。
