Abstract
Both Hemibarbus labeo and H. medius (Cypriniformes: Cyprinidae: Gobioninae) are primary freshwater fishes and are widely distributed. As such, they provide an ideal model for phylogeographical studies. However, the similarity in morphological characters between these two species made the description of their distributions and the validation of species quite challenging. Here we employed variations in the DNA sequences of mitochondrial COI and ND5 genes (2151 bp) to solve this challenge and to study the population genetics structure of these two species. Among the 130 specimens belonging to 8 populations of H. labeo and 9 populations of H. medius from 17 drainage systems in southern China,196 variable sites (9.1% in the full sequences) falling into 50 haplotypes were identified. The haplotype diversity (h) and the nucleotide diversity (π) were 0.964 and 0.019, respectively, indicating a high level of genetic diversity and an evolutionary potential in both species. The result of neighbor-joining tree based on composite nucleotide sequences of the mtDNA COI and ND5 genes showed that the H. labeo and H. medius fell into two major clades (clade1and clade2): clade1was composed of some specimens of Oujiang River, all the specimens of Hanjiang River and Jiulongjiang River, whereas all remaining populations fell in clade2. The genetic distance between clade I and clade II was 0.036, while that between H. labeo and H. medius was 0.027. The haplotype network analyses indicated that the populations of Hanjiang River and Jiulongjiang River had relatively high genetic variation with the rest rivers. The po-pulations of Hainan Island migrated northward to Moyangjaing River. Haplotypes of the rivers of Hainan Island and Moyangjang River had relatively higher genetic variation with the Yangtze River than Pearl River. The populations of Xiangjiang River had no genetic variation with the populations of Guijiang River and Liujiang River. Analysis of molecular variance (AMOVA) indicated that the genetic variance mainly presented in individuals between geographical regions. The genetic variation of populations among regions was 71.2%, the genetic variation among populations within regions was 16.6%, and that within populations within the regions was 12.2%, indicating that most of the genetic variations resided in the populations among regions. The results of mismatch distribution and tests of neutrality suggested that in all populations, H. labeo, H. medius, clade1and clade2 were relatively stable.

Abstract
The Old Order Amish populations in the US are one of the Plain People groups and are descendants of the Swiss Anabaptist immigrants who came to North America in the early eighteenth century. They live in numerous small endogamous demes that have resulted in reduced genetic diversity along with a high prevalence of specific genetic disorders, many of them autosomal recessive. Mitochondrial respiratory chain deficiencies arising from mitochondrial or nuclear DNA mutations have not previously been reported in the Plain populations. Here we present four different Amish families with mitochondrial respiratory chain disorders. Mutations in two mitochondrial encoded genes leading to mitochondrial respiratory chain disorder were identified in two patients. In the first case, MELAS syndrome caused by a mitochondrial DNA (mtDNA) mutation (m.3243A>G) was identified in an extended Amish pedigree following a presentation of metabolic strokes in the proband. Characterization of the extended family of the proband by a high resolution melting assay identified the same mutation in many previously undiagnosed family members with a wide range of clinical symptoms. A MELAS/Leigh syndrome phenotype caused by a mtDNA mutation [m.13513G>A; p.Asp393Asn] in the ND5 gene encoding the ND5 subunit of respiratory chain complex I was identified in a patient in a second family. Mutations in two nuclear encoded genes leading to mitochondrial respiratory chain disorder were also identified in two patients. One patient presented with Leigh syndrome and had a homozygous deletion in the NDUFAF2 gene, while the second patient had a homozygous mutation in the POLG gene, [c.1399G>A; p.Ala467Thr]. Our findings identify mitochondrial respiratory chain deficiency as a cause of disease in the Old Order Amish that must be considered in the context of otherwise unexplained systemic disease, especially if neuromuscular symptoms are present.

Abstract
Malaria is a major public health problem in north-east India mainly transmitted by Anopheles baimai and An. minimus while Anopheles nivipes plays an important supportive role. The genetic diversity of An. nivipes in north-east India was investigated by employing two mitochondrial DNA markers namely NADH dehydrogenase 5 (ND5) and cytochrome oxidase sub unit II (COII). High genetic diversity in An. nivipes was observed by the detection of 16 haplotypes among 30 sequences of ND5 gene and 29 haplotypes among 29 COII sequences. Anopheles nivipes of north-east India was significantly differentiated genetically with that of neighboring South-east Asian An. nivipes as revealed by pairwise FST values of 0.127 (p < 0.01) and 0.044 (p < 0.001) for ND5 and COII genes, respectively, suggesting geographical barriers to gene flow in this species between the two geographical areas resulting in significant population structuring.

Abstract
An approach to deduce the mechanism of stabilization of the hybrid-derived populations in the Ohomopterus ground beetles has been made by comparative studies on the phylogenetic trees of the mitochondrial and nuclear DNA. A phylogenetic tree based on the internal transcribed spacer (ITS) of nuclear ribosomal gene roughly reflects the relations of morphological species group, while mitochondrial NADH dehydrogenase subunit 5 (ND5) gene shows a considerable different topology on the tree; there exist several geographically-linked lineages, most of which consist of more than one species. These results suggest that the replacement of mitochondria has occurred widely in the Ohomopterus species. In most cases, hybridization is unidirectional, i.e., the species A (♂) hybridized with another species B (♀) and not vice versa, with accompanied replacement of mitochondria of A by those of B. The results also suggest that partial or complete occupation of the distribution territory by a hybrid-derived morphological species. The morphological appearance of the resultant hybrid-derivatives are recognized as that of the original species A. Emergence of a morphological new species from a hybrid-derived population has been exemplified.
