人们怀疑加拉戈莫霍里亚的栖息地在很大程度上是支离破碎的，而该物种被认为正在进一步扩展到其活动范围的最南端，以及人类定居点。到目前为止，还没有关于种内分子遗传学的研究发表。moholi。在此，我们估计了g群的遗传多样性和连通性。使用两个线粒体基因区域，细胞色素C氧化酶亚基I基因（COI）和控制区位移环（D-loop）。样本来自南非北部5个地方的档案收藏。对这两个线粒体DNA基因区域进行扩增和测序，以提供群体汇总统计、分化[一个群体的总遗传变异相对于所有群体的总遗传变异的比例（FST）、群体内区域间的分化（ΦST）]、遗传距离和结构。个体之间存在明显的遗传结构，2个coi和6个D-loop单倍型属于两个遗传不同的群体。区域间存在种群分化（FST= 0.670； ΦST= 0.783；P< 0.01）。然而，种群间的分化程度很低，因为单倍型在遥远的种群之间是共享的。邻近种群之间的差异与遥远种群之间的差异一样大。结果表明，遗传渗入可能导致种群之间的连通性，这很可能是由于过去的迁徙或最近包括动物贸易在内的无意易位。
The habitats ofGalago moholiare suspected to be largely fragmented, while the species is thought to be expanding further into the southernmost fringe of its range, as well as into human settlements. To date, no intraspecific molecular genetic studies have been published onG. moholi. Here we estimate the genetic diversity and connectivity of populations ofG. moholiusing two mitochondrial gene regions, the cytochrome C oxidase subunit I gene (COI) and the displacement loop of the control region (D-loop). Samples from five localities in northern South Africa were obtained from archived collections. The two mitochondrial DNA gene regions were amplified and sequenced to provide population summary statistics, differentiation [proportion of the total genetic variation in a population relative to the total genetic variance of all the populations (FST), differentiation within populations among regions (ΦST)], genetic distance and structure. There was discernible genetic structure among the individuals, with twoCOIand six D-loop haplotypes belonging to two genetically different groups. There was population differentiation among regions (FST= 0.670; ΦST= 0.783;P< 0.01). However, there were low levels of differentiation among populations, as haplotypes were shared between distant populations. Adjacent populations were as divergent from each other as from distant populations. The results suggest that genetic introgression, most likely due to past migrations or recent unintentional translocations that include the animal trade, may have led to connectivity among populations.
