在撒哈拉以南非洲，淡水无脊椎浮游动物的分布和物种/谱系多样性研究不足。本文对尼日利亚东南部裸腹蛤科（甲壳纲：枝角类）物种的谱系多样性和区域分布进行了研究。三种Moinidae确定，形态学的基础上，在11个尼日利亚的32个湖泊检查。基于线粒体dna序列（细胞色素氧化酶c亚基i基因; coi）和两个核内转录间隔区（its-1和its-2）研究了它们的系统发育关系。检测到三个品系的大肠杆菌，对应的形态物种。其中两个是新报道的，但一个是全球性分布的，这表明moinids能够长距离传播。有趣的是，两个在形态上属于M。参见macrocopa的线粒体DNA序列具有该种的典型等位基因，参见微型。此外，一个个体在形态上与M.参见macrocopa（也具有M.参见micrura）有一个its-2等位基因，为该种的典型等位基因，一个为M.参见微型。线粒体DNA和核同源性之间的这种不一致性表明了属内不同物种之间的基因渐渗和/或杂交。我们的数据显示谱系分布/多样性和基因渐渗/种间杂交的存在下moinid物种从热带地区。
The distribution and species/lineage diversity of freshwater invertebrate zooplankton is understudied in Sub-Saharan Africa. In the present study, we explored the lineage diversity and regional distribution of Moinidae (Crustacea: Cladocera) species in Southeast Nigeria. Three species of Moinidae were identified, based on morphology, in 11 of 32 Nigerian lakes examined. Their phylogenetic relationships were investigated based on mitochondrial dna sequences (cytochrome oxidase c subunit I gene; coi) and two nuclear internal transcribed spacer regions (its-1 and its-2). Three coi lineages were detected, corresponding to the morphological species. Two of the coi lineages are newly reported, but one coi lineage (and the haplotype found) is globally distributed, suggesting an ability of moinids to disperse over long distances. Interestingly, two individuals that were morphologically M. cf. macrocopa and had its alleles typical of that species had mtDNA sequences typical of M. cf. micrura. Additionally, one individual that corresponded morphologically to M. cf. macrocopa (and also had a mitochondrial sequence typical of M. cf. micrura) had one its-2 allele typical of that species and one typical of M. cf. micrura. This discordance between mtDNA and nuclear phylogenies suggests gene introgression and/or hybridization between different species within the genus. Our data shows the lineage distribution/diversity and the presence of gene introgression/interspecific hybridization among moinid species from a tropical region.
