“…The spiny frog Quasipaa robertingeri is endemic to a narrow region of southwest China and its taxonomic validation is still controversial. Based on COI gene sequences of 110 individuals from seven populations of Q. robertingeri and its related species, we investigated the phylogenetic position and population genetic structure of the species. …”

“…Phylogenetic analyses show that the new species is a member of the C. wayakonei species group and a sister taxon to a clade consisting of C. wayakonei and C. martini based on Maximum Likelihood analyses and Bayesian Inference and differs from its congeners by at least 12.0% genetic divergence in a fragment of the COI gene.…”

“…Caridina incolorsp. nov., a new atyid shrimp from an underground stream of Yaoshui Cave, Daqikong scenic area, Libo County, Guizhou Province, southwestern China is described based on morphology and DNA analysis (mitochondrial COI). Caridina incolorsp. nov. differs from epigean congeners by its smaller eyes which range from reduced to completely blind; colorless body and appendages; long stylocerite and sixth abdominal segment; and relatively large eggs. …”

“…Bangladesh isolates of A. galli constituted a monophyletic clade along with other geographical isolates in the cytochrome c oxidase subunit I (COI) phylogenetic tree, however, we could not clarify the phylogenetic relationships between A. galli and other Ascaridia spp., because their available sequences in GenBank were very few. …”

“…The population structure of three tropical species, A. marmorata, A. bicolor bicolor and A. bengalensis bengalensis, which are distributed widely in the Indo-Pacific region, were explored by means of DNA sequence analysis of mitochondrial cytochrome c oxidase subunit I (COI). This study suggests that A. bicolor bicolor might have two genetically distinct populations (fixation index, F(ST) = 0.891; p < 0.001) that co-occur geographically in the Indo-Pacific region, while A. marmorata and A. bengalensis bengalensis might have a panmictic-population structure in this region. …”

“…The pattern of expression of the genes encoding the mitochondrial forms of aconitase and fumarase corresponded to the profile of the increase of the stress marker gene ZmCOI6.1. It is concluded that the mitochondrial and cytosolic forms of aconitase and fumarase are regulated via the epigenetic mechanism of promoter methylation of their genes in the opposite ways in response to salt stress. …”
