Sequence analysis revealed three different domains and two feature sequences of the control region. The estimated haplotype and nucleotide diversity were 9 and 0.0023, respectively. Genetic structure analysis showed a high-level genetic diversity of B. lenok tisnlingensis (h = 0.6060 ± 0.1499). The AMOVA analysis indicated that 26.02% of total variation came from individual populations, and 73.98% from variation within the four geographic populations, which showed low genetic differentiation between the four geographic groups. Test of neutral evolution and mismatch distribution indicated that no historical expansion occurred in these populations. The high genetic diversity and low genetic differentiation would provide new information for conservation and exploitation of this species.","PeriodicalId":49805,"journal":{"name":"Mitochondrial Dna","volume":"26 4","pages":"532-7"},"PeriodicalIF":0.0,"publicationDate":"2015-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.3109/19401736.2013.865168","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"32017675","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A period of extended isolation on Tobago could result in the Hyalinobatrachium population becoming distinct from the mainland H. orientale. Here, we use 12S and 16S rDNA gene fragments from nine H. orientale specimens from Tobago and the mainland to assess their relationship and taxonomy, as well as the tempo and mode of speciation. The results suggest H. orientale from Venezuela and Tobago are monophyletic and the two populations diverged about 3 million years ago. This estimate corresponds with the drier climate and lower sea levels of the Pliocene glaciation periods. We hypothesize that lower sea levels resulted in land-bridge formations connecting the mainland and Tobago, with a corridor of habitat allowing H. orientale to colonize Tobago to the west of Trinidad.

This study examined genetic variability among P. ambiguus isolated from naturally infected rabbits in four different provinces in China. The partial mitochondrial (mt) cytochrome c oxidase subunit 1 (pcox1), cytochrome b (pcytb) and NADH dehydrogenase subunits 1 and 5 (pnad1 and pnad5) were amplified separately from individual nematodes by PCR and sequenced. The results showed that pcox1, pcytb, pnad1 and pnad5 were 714, 663, 645 and 546 bp in length, respectively. The intra-specific sequence variations within P. ambiguus were 0-1.1% for pcox1, 0-1.2% for pcytb, 0-0.6% for pnad1 and 0-1.3% for pnad5, whereas inter-specific sequence differences with other members of the Oxyuridae were 16.2-17.3% for pcox1, 27.8-30.4% for pcytb, 20.2-24.0% for pnad1 and 27.1-30.3% for pnad5. Phylogenetic analyses using Bayesian inference (BI), maximum likelihood (ML) and maximum parsimony (MP) methods, based on the combined sequences of the four partial mtDNA sequences, revealed that all the P. ambiguus samples form monophyletic groups. This study demonstrated the existence of low-level intra-specific variation in cox1, cytb, nad1 and nad5 genes among P. ambiguus isolates from different geographic regions in China, and these four mtDNA sequences can be used as genetic markers for the population genetic studies of P. ambiguus, as well as the differentiation of P. ambiguus from other oxyurid nematodes.","PeriodicalId":49805,"journal":{"name":"Mitochondrial Dna","volume":"26 4","pages":"501-4"},"PeriodicalIF":0.0,"publicationDate":"2015-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.3109/19401736.2013.855898","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"32016252","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The population genetic structure of O. punctatus in East China Sea and Yellow Sea was examined with a 658-bp segment of the mtDNA COI gene. A total of 60 individuals were collected from five locations and 48 haplotypes were obtained. Mean haplotype diversity and nucleotide diversity for the five populations were 0.9876 ± 0.0068 and 0.0074 ± 0.0041, respectively. Analysis of molecular variance (AMOVA) detected no significant differences at all hierarchical levels, and all FST values were non-significant, indicating that no significant population genetic structure exists in the East China Sea and Yellow Sea. These results supported the null hypothesis that O. punctatus within the East China Sea and Yellow Sea constitutes a panmictic mtDNA gene pool. Neutrality tests and mismatch distribution supported population expansion in this species, indicating that climate change could play an important role in affecting the demographic history of marine species. Strong dispersal capacity of larvae and adults, and ocean currents in the studied area could be the reasons for genetic homogeneity in this species in the East China Sea and Yellow Sea. Another explanation for the lack of phylogeographic structure in O. punctatus might reflect a recent range expansion after the last glacial maximum and insufficient time to attain migration-drift equilibrium.","PeriodicalId":49805,"journal":{"name":"Mitochondrial Dna","volume":"26 4","pages":"559-65"},"PeriodicalIF":0.0,"publicationDate":"2015-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.3109/19401736.2013.873894","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"32042033","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
